Highlights of U li es and Engineering staff ac vi es during the 2014-2015 fiscal year

While we work hard to complete the tasks in front of us and look ahead to the many ini a ves that will improve our opera ons and management of the City of Columbia's wastewater system, it is important to look back and recognize how much we have already achieved.

With comple on of the last two major pump sta on upgrades, the City completed all of the Early Ac on Projects required in the Consent Decree (CD). Addi onally, all seven of the first year deliverable deadlines were met, and the City is on track for mee ng future deadlines.

The City is also moving forward with Supplemental Environmental Projects, having completed the ini al steps of working with key stakeholders to iden fy the specific projects that will be undertaken.

This graphic highlights just a few of the activities Utilities and Engineering staff accomplished during the past fiscal year. Our system is one of the largest

From the Desk of the Wastewater Engineer As we embark on year three of the Clean Water 2020 program and the City’s second year a er the entry of the Consent Decree, I want to let you know that I could not be more proud of the extreme effort exerted by our staff. We have exceeded expecta ons and met every deadline outlined in the Consent Decree, including comple on of the Early Ac on Projects, approval of the Sewer Mapping Program, submi al of annual and quarterly reports, and submi al of the following programs: • Transmission System Opera ons & Maintenance Program (TSOMP) • Maintenance Management Systems Program • Con nuing Sewer Assessment Program (CSAP) • Satellite Sewer System Template Agreements Our con nued success, posi ve results to date, and on-going system improvements have driven our City Council approved wastewater CIP budget up to $80M for FY2015-16. Upcoming projects will include a new 30” force main from the Mill Creek Pump Sta on to the WWTP, replacement of the 24” Smith Branch ou all underneath I-277, improvements to Metro’s WWTP's digesters, mul ple capacity enhancement projects, several pump sta on rehabilita ons and improvements, system condi on assessments, and gravity sewer rehabilita on, just to name a few.

The Compensa on and Classifica on study is complete and will soon be implemented, giving our City staff be er and more compe ve pay and clearer job descrip ons. Our WWTP and WWM Divisions will con nue our drive to becoming a world class u lity and being known as “the place everyone wants to work”.

The City is improving many of our processes and tools used to deliver wastewater services to our customers. Examples include an upgrade to the GIS web mapping system, a formal plan for ongoing sewer system condi on assessment, development of a maintenance management system (Cityworks®) at the Metro Wastewater Treatment Plant (WWTP), and many other ini a ves. Many of these efforts are part of the City’s response to the CD and are described in various deliverables to the EPA. Our wastewater staff has been working hard to develop these reports. By November 2015, we will have submitted 13 of the 20 required deliverables. While much work lies ahead to successfully

Introducing John Riggs, PE John Riggs, PE, an engineer with the City of Columbia, U li es and Engineering Department since 2012, was recently promoted to Assistant Wastewater Engineer. He joined the Clean Water 2020 team to serve as the opera ons and maintenance liaison for the design and construc on of the WWTP and WWM Divisions' capital and special projects.

John Riggs, PE, City of Columbia

John works closely with the WWTP and WWM Superintendents, WW Compliance Manager, City Engineer, and Assistant City Engineer for Design. He reports to Wastewater Engineer, Bill Davis, PE. John received his Bachelor of Science degree in Civil Engineering from The Citadel in Charleston, SC. Professionally he has experience in the areas of gravity sewer design, pump sta on design, elevated water storage tank design, sanitary sewer rehabilita on, water system improvements, and u lity planning studies, among other qualifica ons. Regarding his daily efforts John explains, “Every day presents its new challenges. And, for an engineer like myself, that's what makes us drive forward to be er serve the City of Columbia.

Whether it's analyzing flow from a new development through the Capacity Assurance Program, working with our Clean Water 2020 Program, or assis ng city staff with new and exis ng projects, I thoroughly enjoy walking in the door every day knowing I'll be working with some of the best people I know, toward the common goal of keeping the City of Columbia an awesome place to call home.”

Married in 2006, John and his wife Ashley are proud parents of an eight-month-old son, William. John enjoys spending me working in the yard, woodworking, mountain biking, running and going on the occasional fishing trip down the Broad River.

The Cityworks® Pilot Program The Cityworks® pilot program has been successfully initiated at the Metro WWTP. The pilot program included one process at the WWTP as well as two major pump stations (North Columbia and Broad River).

Maintenance staff are receiving preventive work orders on predetermined schedules, which are generally according to manufacturer’s recommenda ons. Addi onally, Cityworks® Clean Water 2020

gives staff the ability to generate correc ve maintenance work orders when it has determined that a piece of equipment requires a en on.

Very soon pump station maintenance staff will have full functionality of Cityworks® at all pump stations. Asset data (equipment informa on) and condi on assessments for all of the remaining pump sta ons have been collected and assigned and are currently being migrated into Cityworks®.

There are thousands of assets at the WWTP that are integral to the overall operation of the WWTP. Proper operation and maintenance of this equipment is vital to ensure compliance with the City’s National Pollutant Discharge Elimination System permit. Asset data have been collected and condition assessment scores have been assigned for all of this equipment. Currently, this information is being reviewed for quality assurance and quality control purposes. Once this data has been determined accurate it will be delivered to a consultant who will work with the City’s IT Department to test the data and migrate it into the Cityworks® environment.

Cityworks® is not just a computerized maintenance management system; it is a management tool. While it is true that Cityworks® tracks and provides schedules for maintenance of equipment, it also gives the WWTP management staff the ability to track the various types of work ac vi es such as preven ve and correc ve work orders, inspec ons and projects, with their associated costs.

This func onality empowers staff at all levels to access the informa on they need to make wise use of their resources in managing those assets. It also allows them to plan for future repairs and replacements, as necessary, much more predic vely than ever before. This represents a significant step forward in managing the valuable assets at the WWTP as well as all of the City’s wastewater pump sta ons.

The City of Columbia's Capacity Assurance Program

Capacity Assurance was reviewed by the City's new Spirit baseball stadium

In 2013, the City’s U li es and Engineering Department started a Capacity Assurance Program (CAP) with the goal of effec vely managing the capacity of the City’s collec on,

transmission, and treatment systems in order to reduce, eliminate, and prevent sanitary sewer overflows (SSOs). On May 21, 2014, the City entered into a CD with the U.S. Department of Jus ce, the U.S. Environmental Protec on Agency, and SC Department of Health and Environmental Control to resolve alleged Clean Water Act viola ons related to Columbia’s wastewater collec on and treatment system. The CD imposed certain limita ons on the City’s ability to accept wastewater from new service connec ons and on increases in wastewater flow within all areas served by its wastewater system, including all satellite sewer systems that discharge to the City’s wastewater system.

The current CAP enables the City to manage these new service connec ons and increases in wastewater flow to meet the specific requirements mandated by the CD. When performing a capacity analysis, our team employs GIS and water modeling so ware to analyze the exis ng gravity system, pump sta ons, and WWTP capacity downstream of the proposed development to determine if the sewer system has the ability to convey and treat the addi onal wastewater generated from the proposed development. The CAP analysis procedure ensures that our current sewer system is capable of conveying and trea ng the addi onal flow from the proposed development or change-in-use prior to approving the development through the City’s sub-division review staff.

If capacity is not currently available, City staff will work with the developer to plan improvements that will increase the capacity of the wastewater system or provide alterna ve disharge op ons.

Proposed improvements, Crane Creek wet weather SSO or Capacity Enhancement Projects, will enable the system to handle addi onal and future flow to the Metro WWTP. To date, the City has completed 15 major capital improvement projects that have relieved or prevented capacity limita ons across its wastewater service area, with several more in design or in construc on. As a result of the Clean Water 2020

CAP and many other wastewater specific programs, the City has seen a 70% reduc on in the number of SSOs since the 2008/2009 fiscal year.

more reliable and effec ve sewer system in order to allow for future growth and development.

Flow Meters Installed

Sample hydraulic profile used for Pre-CAP review

The CAP enables the City of Columbia to systema cally track and review all new flows prior to their approval for connec on to the wastewater system. Since its implementa on, the CAP has reviewed more than 100 requests to add flow to the City’s wastewater collec on and treatment system resul ng in an addi onal permi ed flow of over 1,000,000 gallons per day. By tracking the exis ng and proposed flows, the City has been able to maintain a well-managed and opera onal sewer collec on and conveyance system.

Through the CAP analysis process, cri cal manholes and high risk areas within the City’s system have been iden fied and have resulted in numerous improvement and capacity enhancing projects. The City con nues working to eliminate capacity related issues, including SSOs, by crea ng a

Flow meter installa on

The City has ini ated a two year temporary and permanent flow metering contract with Woolpert. Installing flow meters fulfills several goals for the City: • Establish Flow Monitoring Standard Procedures under the Con nuing Sewer Assessment Program (CSAP), as described in the CD Ar cle V, Paragraph 14.b.(v) • Long term tracking of inflow and infiltra on trends, in support of the wastewater system hydraulic model calibra on which is referenced in CD Ar cle V, Paragraph 17.

• Assess peak flow capacity of all major Sewer System components under the CAP, as described in CD Ar cle V, Paragraph 12.e.

• Assists the City in their Sewer Overflow Response Program (SORP). Depth sensors in the permanent flow meters can be used to alert City personnel to high water levels.

• Provide the City data necessary to calculate the sewer bill for the City of West Columbia.

“

“

In January of 2015, the City announced the addi on of a Pre-Capacity Assurance Program (Pre-CAP) Analysis which is a new op onal review program for any proposed development that would need new wastewater service.

The Pre-CAP is a planning level tool that provides property owners and developers with an opportunity to have their proposed projects analyzed prior to making a significant investment in the project. While the procedure for the Pre-CAP is essen ally the same as the CAP, the assessment is non-binding for either the City or the developer and can be a useful tool in helping developers be er plan their investments.

Installing flow meters fulfills several goals for the City.

Currently, there are seven permanent rain gauges and 12 permanent meters installed in strategic loca ons of the collec on system. There were 79 temporary meters installed City-wide for two months this spring Flow meter ring installa on in order to complete CSAP requirements and to aid in calibra ng the hydraulic model. The data collected during the metering include base flow, rainfall infiltra on volumes, and peak wet weather flows in different por ons of the collec on system. The data will be used to priori ze areas for inflow and infiltra on reduc on and will also be incorporated into the CSAP and hydraulic model, reducing the projects that result from the priority areas which will help the City present wet weather SSOs and increase capacity in the system.

Willie Abney’s ReƟrement – A er 37 years of service to the City, Wastewater Maintenance Assistant Superintendent, Willie (Blue) Abney, re red on May 31, 2015. To honor Blue for his service, a re rement luncheon was held at Earlewood Park on May 22, 2015. U li es & Engineering Director, Joey Jaco, presented Blue with a beautiful watch, and Wastewater Maintenance Superintendent, Robert Judy, presented him with a commemoratory plaque from the City in apprecia on of his faithful service.

Getac Tablets – In June of 2015, all supervisors and foreman in the WWM Division began using field devices (Getac tablets). These devices, typically used for GIS mapping purposes, will enable staff to identify manhole and line segment asset numbers, direction of flow, and layout of Jason Manchee uses a Getac tablet the surrounding areas.

While tablet use is still in its early stages, foremen are becoming familiar with the tablets functionality while responding to stoppage calls or repairing manholes or mainline brakes.
