WATER RECLAMATION IN WASHOE COUNTY The Ongoing Success of the South Truckee Meadows Water Reclamation Facility 2020 Expansion Project Author: Lana Piskorowski

Nestled in the heart of Washoe County, the South Truckee Meadows Water Reclamation Facility (STMWRF) 2020 Expansion Project is underway.

Collaboratively led by joint venture partners MWH Constructors and KG Walters (MWH&KGW, a Joint Venture), this venture seeks to increase plant capacity, ensuring the county’s wastewater and reclamation needs are met well into the future. This article sheds light on the project’s progress, exemplary concrete work, innovative solutions, and the team’s commitment to positively impacting the community.

A SUSTAINABLE FUTURE THROUGH WATER REUSE A significant component of this expansion is water reclamation, a concept gaining significance in today’s environmental landscape. The STMWRF goes beyond conventional treatment through the process of sending treated water into a reservoir, where it receives additional treatment before being distributed to the local community 6

for farm and landscape irrigation, making it a prominent water reuse facility.

One of the standout technologies employed in this journey is the Biological Nutrient Removal (BNR) process, which removes nitrogen and phosphorus from wastewater before its discharge into the ecosystem. The facility’s commitment to advanced treatment processes ensures the water supplied is clean and suitable for irrigation.

REFLECTIONS ON PAST PROJECTS

Transforming Cape Coral’s

WAT E R

Landscape A Journey of Reclamation and Expansion Author: Lana Piskorowski

In the early 2000s, Cape Coral, a rapidly growing city in Florida, faced a pressing need to develop its water and wastewater infrastructure to accommodate its booming population. This challenge prompted city officials to devise a comprehensive master plan that included the Facility and Utilities Expansion Projects. MWH served as the builder, designer, and engineer for this ambitious undertaking.

noted, “We needed to install this collection, treatment, and distribution system of water to bring Cape Coral into the 21st century.”

THE BIRTH OF A VISION In 2001, the City of Cape Coral began an incredible journey to create a complete water and wastewater infrastructure that would serve the city well into the future. Led by MWH Constructors, the Utilities Expansion Project (UEP) involved the installation of an impressive 720 miles of water, gravity sewer, and irrigation pipelines, along with 240 miles of residential roads and 34 wastewater pump stations.

This herculean effort involved meticulous planning and execution. The UEP’s mission was to efficiently moving clean water from existing treatment plants into people’s residences. Additionally, the UEP seamlessly managed the conveyance of wastewater to reclamation facilities for use in non-potable applications such as irrigation. Evans said, “We recognized the city’s urgent need for a comprehensive overhaul of Cape Coral’s water infrastructure. The city’s growth required a forward-thinking approach that could support the rising demands effectively.”

TRANSFORMING THE LANDSCAPE FOR A SUSTAINABLE FUTURE

The subsequent phase, known as the Facility Expansion Program (FEP), began in 2004 and expanded Cape Coral’s INFRASTRUCTURE water and sewage treatment CHALLENGES IN It is my opinion that a facilities on a massive scale.

WHAT IS A PURPLE PIPE SYSTEM? Purple pipe systems deliver recycled water for industrial use, landscape irrigation, and other non-potable purposes. This distribution occurs through a dedicated network that is entirely isolated from the potable water system.

CAPE CORAL’S RECLAIMED WATER REVOLUTION A pivotal aspect of Cape Coral’s transformation was its water reclamation efforts. The project collected and transported wastewater to the Southwest Water Reclamation Facility, which featured advanced treatment that included primary and secondary treatment followed by tertiary treatment utilizing deep bed filters, resulting in the production of high-quality reclaimed water. This water was stored in 5-milliongallon tanks and repurposed through a purple pipe system for various uses, including irrigation for residential properties and golf courses. Evans stated, “The UEP was the infrastructure that brought the wastewater to the water reclamation facility and also distributed the reclaimed water.” He added, “Recycling water has long been a priority for cities in Florida due to the state’s proximity to the ocean, necessitating sustainable wastewater practices.”

A LEGACY OF SUCCESS As the Cape Coral project unfolded over years of dedication and perseverance, it garnered numerous accolades, including the 2011 ENR Southeast Best of 2011 Project Award and the 2011 DBIA National Design-Build Award. Remarkably, the project achieved over 3.3 million work hours with only one lost-time incident, a testament to the meticulous planning and safety measures implemented. Evans concluded, “Cape Coral’s journey was about more than infrastructure; it was about shaping the city’s future. Our success was a collaborative effort that demonstrated what vision and dedication can achieve.”

Leading the Way in For a Sustainable Future Author: Alexis Gee

Water reuse is rapidly emerging as a crucial solution to address water scarcity and promote sustainable water management practices worldwide. While wastewater treatment plants have long been associated with sewage treatment, an underlying role often goes unnoticed; these plants are pivotal water recycling facilities.

MWH has a noble reputation as a leading global construction firm that specializes in water infrastructure and delivers innovative water reuse projects. Our commitment to providing resilient, dependable, and high-quality water sources has earned our firm a distinguished reputation in the industry. To get the complete picture of MWH’s impact on the rise of water reuse, we sat down with two MWH subject matter experts: Dr. Marco Aieta, a seasoned MWH alumni currently serving as Senior Consultant, and Kiersten Lee, PE, Vice President and Director of the Construction Services Group.

PAVING THE WAY FOR MODERN-DAY WATER REUSE MWH’s 200-year-old roots are deeply intertwined with water reuse. At the turn of the 20th century, John D. Watson, the source of the “W” in MWH, was a pioneer in the development of sewage purification.

He also constructed the first large percolating filter plant, an innovative departure from age-old methods of land treatment. Then, in the early 1970s, James M. Montgomery, Inc., became part of pioneering research and feasibility studies on some of the first advanced reuse projects in the country, including Orange County Water Factory 21 Thirty years later, MWH developed, designed, and constructed the US’s first semiconductor water reuse facility for a global manufacturing client.

The $417M project addressed the client’s need for additional pre-treatment of industrial wastewater before its discharge to the municipal sewer system.

Now operational, the facility includes advanced water treatment and reuse systems that enable the reclamation of the treated effluent, reducing the client’s need for potable water and making it 16

available for use on-site. Recycled water is vital for manufacturing plants like this due to their immense water requirements for cooling towers, chillers, and scrubbers. By recycling and reusing water, semiconductor manufacturers are making significant strides toward becoming more environmentally conscious.

REDEFINING REUSE Clean potable water is not usually the first thing to come to mind when thinking of wastewater

Thirty years later, MWH developed, designed, and constructed THE FIRST SEMICONDUCTOR WATER REUSE FACILITY IN THE US for a global manufacturing client.

treatment plants. In fact, most people shudder at the idea of treated wastewater ending up in their water supply. However, those concerns can be quelled by understanding the treatment process and the importance of reusing or recycling water.

Dr. Aieta illustrated the concept: “Imagine two cities are geographically linked by their connection to a river system. One city’s municipal wastewater treatment plant is upstream and discharges clean, treated water into the river, while the other city’s water treatment plant is downstream, with an intake from the same river, which it then treats and distributes to its customers--that’s reuse.”

Building on Dr. Aieta’s explanation, Kiersten Lee agreed, “In 99 percent of cases, the water

are just as important. Lee explained that “water is just one resource that you can recover. For example, the intent of one of our major Solids Management projects in Texas is to capture and create energy from methane gas…essentially, waste is getting reduced to a point where energy can actually be created from it. To me, that’s very cool!”

The Riverside Park Water Reclamation Facility in Spokane, WA, is an excellent example of this concept. MWH and Slayden completed significant upgrades to this facility in 2021, adding a new membrane filtration system that significantly reduces phosphorus and other pollutants, commonly referred to as the Next Level of Treatment. This greatly improved the quality of effluent released to the Spokane River.

The San Francisco Public Utilities Commission’s Southeast Treatment Plant Biosolids Digester Facilities project also focuses on resource recovery.

As the Construction Manager/General Contractor for this $1.78B project, MWH is installing an innovative process that turns wastewater sludge into Class A Biosolids, which can be used as fertilizer. This transformation of waste into something with utility bridges the gap between traditional treatment and innovative reuse.

These facilities play a vital role in the future of humanity, especially as water scarcity and fossil fuel depletion become more and more prevalent.

Knowing this, municipalities across the US have been rebranding their wastewater treatment plants as “resource recovery” or “water reuse” facilities for over a decade. The public perception of reusing treated water for potable and non-potable uses is one of the top reasons for this major rebranding, but the valuable resources that these facilities generate

WATER REUSE: AN ESSENTIAL TOOL Water reuse, or water recycling, is the process of intentionally capturing wastewater, stormwater, saltwater, or gray water and appropriately cleaning it for designated beneficial purposes, including drinking, watershed restoration, industrial processes, and surface or groundwater replenishment.

MWH has been a champion for the responsible 17

management and reuse of water for over 200 years. With an ethos of environmental sustainability and community stewardship, MWH has been instrumental in furthering the progress and adoption of water reuse for both public municipal and private semiconductor fab projects.

Semiconductor clients utilize fresh and reclaimed water, drawing from utilities, on-site wells, and even desalination processes in coastal regions. These clients reduce freshwater consumption and enhance overall sustainability by maximizing water reuse and conservation efforts.

Speaking about the semiconductor industry’s focus on water reuse and building zero liquid discharge facilities, Lee stated, “Water reuse is important for global manufacturers as well as the communities where their factories are based due to the tremendous impact on local water sources. These large companies are taking a more environmentally sustainable approach because they know how much water they need and care about the water they discharge.”

Lee continued, “People usually think that industrial water reuse plants are so chemical-heavy, and they’re just all advanced treatment processes. The cool thing is that’s just not the case.” Each treatment facility is unique, but for many of MWH’s semiconductor fab projects, a combination of traditional and advanced treatment processes is utilized. “The MWH team actually proposed the idea to utilize a biological process called a BNR, or biological nutrient removal, at the first semiconductor reuse facility in the US. There are nuances to it, but to put it simply, there’s a basin with organisms that actively remove critical constituents, like nitrogen and phosphorous, but for that project, it was ammonia.”

THE NEVER-ENDING CYCLE “The real story is: it’s all water. It begins as rain, ends up as seawater, and eventually cycles back to rain. In between that timeframe, humans use and contaminate it and subsequently make efforts to purify it before it reintegrates into the natural cycle,” Dr. Aieta noted. “If we do a good job of that, we don’t damage the natural system. We can recycle the water and live in harmony with nature. But, if we don’t do a good job of that, it leads to detrimental outcomes. All of these systems are tied together if you think about it.”

MWH’s long-standing dedication to water reuse demonstrates our commitment to promoting sustainable water management practices, and our innovative projects and collaborations with industry leaders signify a promising future for water reuse initiatives. As water scarcity continues to be a pressing global issue, MWH’s expertise will be pivotal in securing a reliable and sustainable water supply for communities and industries worldwide.

REFLECTIONS ON PAST PROJECTS

WATER RECLAMATION AT SPOKANE’S

RIVERSIDE PARK Author: Lana Piskorowski

No discussion on water reclamation would be complete without acknowledging the remarkable accomplishments of the Spokane Riverside Park Water Reclamation Facility.

The facility secured the Award of Merit in the water and environment category during last year’s Engineering News-Record Northwest Best Projects competition.

“It’s incredibly rewarding to be part of a company dedicated to environmental betterment,” noted Andrew Pharis, Director of Operations at Slayden, “In this project, we lowered phosphorus levels and enhanced effluent quality. The restoration of the Spokane River holds the promise of healthier aquatic life and revitalized fish habitats.”

As Spokane’s oldest and most extensive water recycling center, the Riverside Park Reclamation Facility caters to a community of 210,000 residents, providing a combined storm and sanitary sewer system. It processes about 34 million gallons a day (mgd) of wastewater, with peak flows over 150 mgd. The treated water is then released into the Spokane River, underscoring the facility’s crucial impact on the local waterway.

The project utilized an advanced membrane filtration system, the Next Level of Treatment, featuring at the time the largest membrane system of its kind. Opting for the Pall Aria™ FLEX system was motivated by its noteworthy cost efficiencies, superior water recovery, simplified integrity testing, reduced maintenance needs, and streamlined construction process. This customized system successfully met the objective of curbing phosphorus levels, enhancing phosphorus removal from the Spokane River discharge to an impressive 99%.

The new system improved the vitality of the river and increased the removal of heavy metals, PCBs, and hazardous pollutants. Future UV disinfection will advance treated water to Class A standards, paving the way for its reuse in irrigation, wetland augmentation, and groundwater recharge. Jeff Wall, Vice President and Senior Project Manager at Slayden recalled, “Being involved in the Spokane project was truly exciting.

In light of skyrocketing freshwater demands and ever-intensifying weather shifts, the imperative for establishing sustainable water infrastructure becomes even more pronounced. As a firm with a 200-year history steeped in water and wastewater treatment innovation, MWH partners with municipalities, public utility providers, and private industrial clients to effectively tackle water quality and scarcity challenges.

Advancing water reuse is an increasingly attractive solution that will address a diverse array of intricate water management issues, from bolstering the resilience of water supplies in the face of mounting pressures to accommodate growing populations to mitigating saltwater encroachment. Water reuse is important because it aids in mitigating the impacts of severe weather events and sewer overflows, providing a comprehensive approach to adapting our water systems to the changing environment.

We constantly focus on is how to be good stewards of water when there’s no water around.

When discussing non-potable reuse, MWH’s Vice President and Director of Construction Services, Kiersten Lee, PE, explained, “Our team is always focused on reusing water during construction. We seize as many opportunities as possible to use nonpotable water for dust control, hydrostatic testing, concrete, and commissioning.”

Non-potable reuse is not new, but MWH consistently tries to find better ways to drive sustainability. “One of the innovative things that we constantly focus on is how to be good stewards of water when there’s no water around,” remarked Lee. “On the Southern Delivery System project, we built 15 miles of pipeline, three pump stations, and a 50 MGD plant in the middle of nowhere. There was a lot of effort to successfully move and store water so we didn’t have to discharge and bring new water out there. Now, we use the lessons learned from that Colorado Springs project to benefit water-scarce project sites, such as the Portland Water Bureau’s Bull Run Filtration and Pipeline projects.”

DIRECT & INDIRECT POTABLE REUSE (DPR/IPR) Water reuse for non-potable applications has long been accepted and is a successful means of maintaining freshwater supplies. Though it may not be common knowledge, revitalizing aquifers and augmenting water supplies with reused water has been happening for years and continues to escalate today as the world experiences greater water scarcity.

“Depending on where you live, you’re already consuming reused water, whether you know it or not,” Lee advised. “Municipal wastewater and drinking water are more regulated and more closely monitored than bottled water, which is regulated by the Food and Drug Administration.”

DPR involves treating wastewater to a level that meets or exceeds drinking water quality standards.

This treated water is then introduced directly into the potable water supply. Advanced treatment processes are utilized, including: 6 Microfiltration and Ultrafiltration: These

processes use fine membranes to remove particles, bacteria, and some viruses from the water.

6 Reverse Osmosis: This high-pressure process

forces water through a semipermeable membrane to remove salts, dissolved solids, and contaminants.

6 Advanced Oxidation Processes: Techniques like

UV (ultraviolet) and ozone treatment break down organic and chemical contaminants.

IPR involves injecting treated wastewater into nonpotable water sources, allowing natural processes to purify the water further before it’s used for potable purposes. Key steps include: 6 Advanced Treatment: Similar to DPR, advanced

treatment technologies are employed to ensure high-quality reclaimed water.

6 Aquifer Recharge: Injecting treated water into

underground aquifers provides natural filtration, with the soil and rock acting as a barrier against contaminants.

6 Groundwater Recharge and Recovery: After

a period of underground storage, the water is pumped out and treated further before entering the drinking water system.

“Just because water comes from an aquifer doesn’t mean it hasn’t been blended with treated water from a municipal source,” Lee commented. “If one community is doing deep well injection to recharge its aquifer, wells downstream pull water out of the same aquifer to serve the surrounding community.”

21

INNOVATIVE WATER REUSE TECHNOLOGIES Other cutting-edge water reuse technologies include: 6 Membrane Bioreactors (MBR): Combining biological

treatment with membrane filtration, MBR systems efficiently remove organic matter and pathogens, producing high-quality reclaimed water.

6 Forward Osmosis (FO): FO utilizes osmotic pressure

to draw water through a semipermeable membrane.

It’s being explored for desalination and concentrating wastewater, thus reducing disposal volumes.

6 Electrochemical Processes: Technologies like

electrocoagulation and electrooxidation use electrical currents to treat wastewater, removing contaminants and producing reusable water.

6 Nanotechnology: Nanomaterials can be employed

in water treatment processes, such as nanofiltration and adsorption, to enhance contaminant removal and increase efficiency.

6 Smart Water Management: Integration of sensors, real-

time data monitoring, and predictive analytics enable optimized water reuse operations, minimizing energy and resource consumption.

6 Biofiltration and Natural Systems: Constructed

wetlands, natural filtration basins, and living machine systems mimic biological processes to treat wastewater in a sustainable and ecologically friendly manner.

We are determined to build systems that make people feel confident that reclaimed water is to drink. As an industry, we have to succeed in building confidence in water reuse to ensure water security for the future.

KIERSTEN LEE Vice President and Director of Construction Services

“We are determined to build systems that make people feel confident that reclaimed water is to drink,” Lee explained. “As an industry, we have to succeed in building confidence in water reuse to ensure water security for the future.”

While water reuse technologies offer promising solutions, challenges remain, including public acceptance, regulatory frameworks, and upfront investments. With increasing awareness of water scarcity and sustainability, innovative water reuse technologies have the potential to revolutionize how we manage and conserve water resources for generations to come.

out of college at the time. It was intimidating being around all the senior professionals and the high expectations. It gave me the motivation to excel and learn in order to keep up to speed,” recalled Rusciolelli.

California’s abundant population and susceptibility to arid conditions in the western region positioned it as a focal point for water reuse advancement.

Based in Pasadena, JMM played an active role in this landscape. As the late 1960s ushered in the era of advanced water reuse systems, JMM became deeply involved in numerous projects and feasibility studies. In the next twenty years, they experienced significant growth. JMM designed treatment facilities for the Metropolitan Water District of Southern California (MWD) and San Diego Water in Southern California, expanding with new offices in Northern California and acquiring various

MWH’s Construction Management Services (CMS) West Department proudly carries JMM’s construction management legacy into today. Dean Rusciolelli, now Senior Construction Manager for CMS West, shares his connection to JMM. “My time with JMM was interesting. My dad was an electrical engineer for Cutler-Hammer, who worked with JMM guys way back in the 60s, 70s, and 80s.

He always bragged about JMM, emphasizing how they were the elite engineers of the day and how he enjoyed working with them. So, when I joined the company, I was really thrilled and proud. I was right

clients in the water and wastewater sectors. In a significant milestone, JMM published “Water Treatment: Principles and Design” in 1985—a comprehensive work addressing fundamental aspects of water quality crucial for water reuse and still cited in reclamation studies.

This pivotal text was originally intended to be a textbook, but it evolved into something even more impactful. The book became the go-to reference in the industry for water treatment facility design, from basic science and design principles to operational considerations.

Dr. Marco Aieta, an MWH veteran currently serving as Senior Consultant, was recruited by Rhodes Trussell of JMM in 1986 to lead their Applied Research Department. “Back then, the EPA introduced a wave of new regulations, and we would do pilot studies for our clients to determine the best way to meet those regulations. We had over 100 publications,” notes Aieta. “The work we did formed the foundation for the technology that is used today for direct and indirect potable reuse. It also formed the foundation for current technologies used for groundwater cleanup.”

Interestingly, Dr. Aieta’s wife, Jennifer Aieta, wrote all the sample problems and was the technical editor for the third and final edition of Water Treatment: Principles and Design. After working at MWH for a decade, Jennifer went on to start her own firm in the 2000s. “She’s the really smart one in our family,” Dr. Aieta remarked.

Dr. Aieta’s work with JMM began years earlier, in 1975, when Orange County introduced Water Factory 21, a substantial reclaimed water facility utilizing reverse osmosis to treat wastewater.

The treated water was injected into the ground, creating a hydraulic saltwater barrier to counterbalance the overdrawn groundwater aquifers in the area. JMM conducted viral assays and provided technical direction for the virus phase of the project, contributing to wastewater contaminant removal at Orange County Water Factory 21. Over three years, the James M. Montgomery Environmental Research Laboratory was used to conduct virus monitoring. Eventually, Water Factory 21 moved a step further into direct potable reuse, being one of the first facilities in

California to do so. “My history with Water Factory 21 goes way back to my Stanford days. I worked alongside Perry McCarthy, a celebrated professor at Stanford, analyzing data for the facility. It was the early 1980s when computers took up an entire room,” recalled Aieta.

The work we did formed the foundation for the technology that is used today for direct and indirect potable reuse.

JMM’s Applied Research Department, under Aieta’s leadership, tackled a project for the city of Pasadena to address significant groundwater contamination from the Jet Propulsion Laboratory (JPL) in the Devil’s Gate region of the Arroyo Basin. Aieta’s team studied a then-emerging technology called advanced oxidation, focusing on methods such as UV/O3, UV/ H2O2, O3/H2O2, and more to neutralize the toxic compounds. “Advanced oxidation is all based on the fundamental scientific concept of free radicals.

When you generate free radicals, they don’t exist very long, but in the presence of the contaminant, they will oxidize and break apart those target compounds,” explained Aieta.

to remove most of the compounds down to nondetectable levels without detrimental byproducts.”

The team decided to elevate the scale of the pilot study to that of a demonstration project, running at roughly 1000 gallons a minute. “We designed the facility and built it in the North Hollywood wellfield.

It was a turnkey job and may have been the first construction job MWH ever did,” Aieta noted.

Such studies have significantly influenced the development and implementation of modern water reuse technologies and systems. They stand as a testament to JMM’s enduring impact on advancing sustainable water practices. Aieta aptly encapsulates their legacy: “In the very beginning, we developed the science for water reclamation and reuse, then we took the science to the industry and helped them develop the technology that is now being used in the field.”

The focus of JMM’s research efforts shifted to San Fernando Valley, where the Los Angeles Department of Water and Power (LADWP) heavily relied on well water. Collaborative efforts led by Bill Glaze of UCLA and Aieta introduced advanced oxidation processes, seeking to address historical contamination from Lockheed Martin’s World War II activities. Aieta notes the project’s success, “We worked together with LADWP to do a long study for them where we looked at implementing ozone peroxide advanced oxidation. Our research results showed we were able

SAFETY WEEK 2023 Author: Alexis Gee

Safety is the foundation of every MWH project.

Recognizing the importance of ensuring the wellbeing of every individual on the job site, MWH proudly sponsored Construction Safety Week 2023 in May. The core ethos of this annual week-long event is understanding that safety is not just a series of procedures and protocols but a culture that empowers every person on-site to be safe and aware of their surroundings. By joining forces and setting aside competition, MWH and over 70 other construction firms demonstrated their commitment to celebrating the hard work and dedication of those prioritizing safety as the foundation of their work.

STRONGER & SAFER TOGETHER This year’s Safety Week focused on strengthening the construction industry’s safety culture and performance. Craft professionals, project leaders, and business executives were empowered to speak up and act on any potential risks, emphasizing the importance of collective responsibility. Safety Week also advocates for improved safety processes, mental health resources, and equipment standards

The efforts that we put into safety week are for our people.

In construction, success is not just measured by the finished project but by the stories of lives protected.

to reduce the risk of injuries and create safer work environments. Building a holistic safety culture encompasses physical well-being, mental health, and a focused mindset.

MWH’s commitment to safety extends far beyond Safety Week, emphasizing the need for continuous improvement and a steadfast dedication to safety on every job site, every day. Senior managers were encouraged to lead from the front by attending and engaging in weekly safety meetings, pre-shift meetings, Improve It walks, and Stretch and Flex sessions. By evaluating the effectiveness of safety culture at each job site, senior managers can provide valuable feedback to improve safety practices companywide. This hands-on involvement of senior managers underscores MWH’s commitment to fostering a safer industry and reinforces the importance of safety at all levels of our organization.

LIFE-SAVING DAILY TOPICS To understand the importance and impact of this critical week, we spoke with MWH Regional Health & Safety Manager Luke Tallant, CHST, and Slayden Regional Health & Safety Manager Lendel Del Cid, GSP. “Safety Week is a good platform for spreading knowledge and cultivating a strong culture of safety that lasts. Each year for Safety Week, we always try to bring in vendors or outside resources to spend 20 to 30 minutes with the crews,” Luke Tallant explained. “We shut the jobs down and do nothing but talk about safety and the daily topics.” Safety Week 2023 covered various topics to promote safety awareness. MWH, Slayden, and Methuen crews across dozens of job sites took part in daily activities and toolbox talks, which provided valuable insights and practical guidance to empower all those on-site to make safe choices.

1

DAY 1: ENGAGEMENT The week began with reflective sessions on the mission of Safety Week and discussions of how to maintain a personal commitment to safety. “You can really tell that it brings safety to the forefront of everyone’s mind,” Tallant remarked while reflecting on how crew members act during and after Safety MWH Crews in Beaverton, Oregon during Safety Week Week. “The efforts that we put and fix or correct the issue,” Tallant remarked. These into safety week are for our people,” stated Lendel weekly safety submissions must be corrective or Del Cid. Building strong teams who work safely serve as a teaching moment and be high quality, is the most important job for everyone on every meaning they must include a photo, a description, construction site, and those who are empowered and a due date based on the severity or risk to step in, speak up, and work together to stop associated with the safety item. anything that risks safety.

2

DAY 2: RISK IDENTIFICATION Day two’s toolbox talk delved into the concept of risk identification. Participants were encouraged to acknowledge error-prone situations and utilize evaluation processes to identify hazards and critical task steps to ensure safety. “People have to be hyper-aware of their surroundings, because so much changes during construction, not just on a daily basis but even minute by minute,” mentioned Tallant.

Not all hazards are apparent or easy to recognize, even to those who see and face them every day-some hide in plain sight.

MWH takes great strides to provide environments where employees are empowered to sharpen their safety skills, help their fellow team members, and maintain a safety-first mindset. Our Improve-Its Program implores field personnel to identify ways to complete tasks related to construction equipment and processes safely and efficiently. “If someone sees something in the field, they can honestly whip out their phone, take a picture, put it in the system, and in real-time, it goes to the people associated with that risk so they can get right back out there

“Improve-Its allow us to rapidly address safety concerns,” Tallant explained, “They give us insight into what topics we should go over with each crew to increase safety awareness and preparedness.”

Logging and categorizing Improve-Its are vital in identifying leading indicators needed to take a proactive approach to safety management and training. In 2022, MWH exceeded the goal of generating 10,000 Improve-Its. This year, MWH updated the Safety Improve-It and Safety Observation quota for project teams, requiring one Improve-It/Observation per person per week.

DAY 3: FALL PREVENTION Safety Week’s Fall Prevention Day aligned with OSHA’s National Safety Stand-Down to Prevent Falls in Construction. Falls are preventable, but in 2021 alone, 38% of construction industry deaths were due to falls from elevation (OSHA, 2023). “We brought in third-party trainers to do fall protection presentations where they bring a special truck and drop a dummy outfitted with an old harness that was known in the industry years and years ago,” Tallant commented. “This allows us to compare the old to the new technology that we have for fall protection

27

with retractable and other critical features like that, which really opens everyone’s eyes to see the difference and the true impact of a fall.”

On Fall Prevention Day, Slayden Regional Health & Safety Manager Lendel Del Cid was on-site at the Geren Island Water Treatment Plant Ozone Upgrades project in Salem, OR—a project that requires working in confined spaces. “We had Ritz Safety do a confined space training, and while the trainer was explaining the importance of the air monitors and sufficient oxygen, one of our Superintendents spoke up to share a story.” Del Cid recounted how Kenny Pollard, a Superintendent who’s been with Slayden for over 30 years, shared a harrowing experience with 45 to 50 crew members listening, “he described how a former coworker went down in a confined space and how it could have been a life-threatening situation if all of the proper safety protections had not been in place. When stories come from someone other than the safety guy, it really hits home.”

The most rewarding part of my job is seeing that even when I’m not on site, people still call when they have questions or concerns. They’re not afraid to reach out to the safety department, and that just goes a long way in showing that we have built that culture where everybody wants to be their brother’s keeper.

Although Pollard’s story would be a stark reminder for almost any worker, the crew listening that day was particularly impacted because they had just celebrated one of their team members receiving a spot bonus for vigilantly monitoring air in a confined space. “Had the employee become complacent with the air monitoring procedure…it could have been very, very serious,” Pollard noted.

4

DAY 4: CONTINUE LEARNING Interactive demonstrations led by experienced crew members empowered attendees to share their knowledge while promoting safer and more efficient work practices. “That day gave us the opportunity for seasoned veterans to speak up on some of their own experiences throughout their careers and be able to pass that knowledge along to the newer employees,” Tallant explained.

“Listening to seasoned workers like Kenny tell stories about unforgettable safety situations not only relates to the training but also drives home the idea that no matter how safe we think we’re being, we’re not going to do anything until we have every safety measure in place,” noted Del Cid. “We have to be prepared for the worst, even if we’re doing everything right.”

5

DAY 5: SILICA AWARENESS On the final day of Safety Week, our toolbox talks shed light on silica exposure’s hazards and health effects. “Silica is always a big one for us because it’s still relatively new, even though it’s been about six years since the whole standard changed,” explained Tallant. Participants learned about preventive measures to minimize overexposure and protect their health.

Crystalline silica is a common mineral found in construction materials such as sand, stone, concrete, brick, and mortar. When materials containing crystalline silica are cut, ground, drilled, or crushed, a fine dust known as respirable silica dust is created. Because it’s 100 times smaller than a grain of sand, people can unknowingly inhale silica dust, potentially leading to the development

where everybody wants to be their brother’s keeper.

They work together on a daily basis and use all the resources they have to make sure that they don’t put themselves or anyone else at risk.”

of lung cancer, silicosis (an irreversible scarring and stiffening of the lungs), kidney disease, and chronic obstructive pulmonary disease.

To limit exposure to silica dust, MWH requires all employees and subcontracted personnel to be trained in silica awareness and how to utilize the “Specified Exposure Control Methods When Working with Materials Containing Crystalline Silica” Table issued

by OSHA. MWH also established and implemented a Written Exposure Control Plan, which guides field personnel in limiting operational silica exposure and documenting cases of worker exposure.

Agreeing with Tallant, Del Cid commented, “We celebrate our safety and our people. These kinds of milestone celebrations go a long way. They show our people how much we appreciate their dedication and hard work. In construction, success is not just measured by the finished project but by the stories of lives protected.”

Safety Week 2023 served as a rallying point for the construction industry, uniting companies, workers, and leaders under a common goal: building a stronger, safer industry. The collective efforts of MWH and over 70 other top construction firms exemplify the commitment to making safety a fundamental aspect of every construction project.

Safety Week empowers individuals at all levels to be strong voices and make safe choices through engaging toolbox talks, interactive demonstrations, and hands-on involvement. By continuously improving safety practices and fostering a culture of shared responsibility, the construction industry can create safer work environments, protect workers’ well-being, and positively impact the communities they serve.

Together, we build a safer industry for the present as well as the future.

He was knighted by Austria, Denmark, Brazil and Sweden for his contributions to water infrastructure

In July, we celebrated the birthday of the earliest founding name of MWH: Thomas Hawksley. But who was this innovator from 216 years ago?

In the annals of engineering history, few names shine as brightly as Thomas Hawksley. Born on July 12, 1807, Hawksley’s legacy as the preeminent water engineer of the 19th century remains an indelible mark on the world of infrastructure and innovation.

Hawksley’s journey into the realm of water had humble beginnings. He cut his teeth as an apprentice under the guidance of architect and surveyor Mr. Edward Staveley at the tender age of 15 with limited formal education. Hawksley’s innate curiosity and determination propelled him forward, leading to a path of self-guided learning that would ultimately define his exceptional career.

Just eight years later, at age 23, Hawksley was appointed Chief Engineer of the Trent Waterworks Company. It was a role that would prove pivotal in shaping the trajectory of his contributions to the world of water infrastructure.

During his lifetime, many engineers resigned themselves to the belief that pressurized water supply systems were an untenable dream due to the seemingly unavoidable occurrence of heavy leaks. However, Hawksley’s unyielding determination and innovative spirit led him to collaborate with an ironworks company and local plumbers. Together, they devised a series of robust and easily repairable pipe fittings, effectively tackling potential leakage.

At age 25, Hawksley’s celebrated his first major achievement with the realization of the Trent Bridge Pumping Station—a groundbreaking project that birthed the country’s inaugural pressurized water system. This system, serving the City of Nottingham, stood as a triumph of Hawksley’s persistence and forward-thinking approach. Little did he know, this achievement would be a saving grace for the city in the coming years.

Sixteen years later, when the specter of cholera reared its deadly head in Nottingham, the city remained remarkably untouched. Thanks to Hawksley’s visionary pressurized water system, Nottingham’s residents were spared from the

devastating effects of the disease.

Hawksley’s impact spread far beyond his homeland as he led the design and construction of over 150 waterworks systems in the United Kingdom and abroad. His influence earned a knighthood from Austria, Denmark, Brazil, and Sweden—a testament to his global contributions to water infrastructure.

At 59, Hawksley joined forces with his son Charles to establish T&C Hawksley, a partnership that would later merge with JD & DM Watson, ultimately giving rise to Watson Hawksley—the namesake of the “W” that now graces MWH. Hawksley also became the president of both the Institution of Civil Engineers and the Institution of Mechanical Engineers—a testament to his stature within the engineering community.

As we reflect on Thomas Hawksley’s life, we honor a man whose indomitable spirit and visionary contributions have left an enduring legacy that we continue to uphold today at MWH. His innovations continue to ripple through time, a source of inspiration for our work, reminding us that the boundless horizons of human achievement are limited only by our imagination and determination.

Dedicated to Water Reuse Author: Alexis Gee

With a career spanning over a decade, Kiersten Lee, PE, PMP, has established herself as a prominent figure in the field of commissioning and start-up management.

Kiersten started her construction journey as an intern at MWH, and she has overseen and participated in the successful launch of numerous high-profile projects, earning her a stellar reputation as a water reuse and resource recovery expert across the industry.

ON THE CUTTING EDGE OF WATER REUSE Of her countless achievements, one of the most significant was Kiersten’s instrumental role in operating the first semiconductor water reuse facility in the US. This was a landmark project for the progress of water reuse adoption nationwide.

“Although MWH built the nation’s first semiconductor water reuse plant, this type of facility is not new. We had a smaller version in Israel, and manufacturers across the Pacific Rim have already been doing this.

The US is a bit behind the curve, but if we want to bring manufacturing back, we need to be thinking about how to manage the waste streams associated with this kind of manufacturing.”

over 100 million gallons of water, and recently they achieved the billion-gallon milestone—a win for the manufacturer, the local community, and the environment.

Lee emphasizes that major industries have a significant role to play in water consumption and discharge, making them central to the conversation about sustainability. “Getting to a point where we can comfortably and confidently use reuse processes for our wastewater in a potable sense—that’s a critical hurdle,” Lee remarked.

PASSION FOR ENVIRONMENTAL SUSTAINABILITY Anyone who works with Kiersten knows that conserving the environment is one of her passions. “I’m Captain Planet at heart, and I’m a huge proponent of eliminating the use of bottled water,” Lee remarked, “Treatment plant discharges are regulated by the EPA, while bottled water is regulated by the FDA. The FDA tries to keep up with the EPA’s drinking water regulations, but sometimes, the FDA’s quality and safety regulations diverge. So bottled water is not as regulated as tap water, and it produces tons of plastic waste.”

Lee’s commitment to sustainability and technical excellence is evident in her work as a key project lead for the $1.3B Bull Run Filtration Facility and Pipeline Program in Portland, OR. In the face of environmental restrictions and a lack of discharge structure, she developed 16 options to effectively treat and reuse nearly 20M gallons of test water.

Releasing the treated water into the environment is impossible, and hauling the water would cost $7 per gallon, equating to $140M for disposal. Having dealt with the same issue on the $825M Southern Delivery System project in 2013, Lee conducted site visits and coordinated with local businesses to develop an option that allowed the test water to be treated before being donated to local landscaping nurseries via the existing irrigation pipelines.

Working with a global semiconductor manufacturing client, MWH constructed the innovative $400M manufacturing facility, which blends traditional and advanced treatment processes to achieve critical water reuse goals. Within the first year of owner operation, the facility’s state-of-the-art water reuse system reclaimed 38

“We didn’t want to take the easy way out by discharging and bringing in more water. We came up with innovative ways to be better stewards of water.”

As a passionate construction professional with a soft spot for the environment, Kiersten Lee continues to raise the bar in engineering excellence. Her expertise, leadership, and innovative problem-solving skills have solidified her position as a trailblazer in the industry.
