2014

SILICON VALLEY ADVANCED WATER PURIFICATION CENTER

Santa Clara Water District, San Jose, CA community needs for irrigation of urban and public grounds and spaces, agricultural use, construction, dust mitigation, industrial uses, and more. These practices can be expanded and better integrated into urban planning practices for communities that do not have immediate reuse needs but are on a trajectory to have climate change and system resilience-driven needs in the near term. The remaining challenge is to incorporate integrated water recycling and total resource management strategies, which include elements of non-potable, indirect potable, and potable reuse, into capital planning. Only then will utilities be able to respond to the cyclic nature of the water cycle and the climate change-driven extreme events in a purposeful manner. Communities can achieve this by coupling thoughtful policy approaches with fitting technology solutions.

Regional approach to augmenting drinking water supplies.

Several technology developments make this a particularly exciting time for reuse.

Treatment intensification. Technology solutions that can enable potable reuse – such as new membrane technologies that serve as alternatives to older technology and also intensify wastewater treatment while producing

PROJECT

Public Utilities Board (PUB), Singapore higher-quality feed water for advanced treatment or integration of biofilm technologies as part of advanced treatment integrated with or downstream of intensified wastewater facilities can result in smaller-footprint facilities, save energy and reduce carbon emissions, and ultimately preserve and retain a valuable resource – water.

System integration and optimization. Further integration of monitoring and targeted removal of chemical compounds of concern can alleviate the risk of occurrence of peaks if any of these compounds were to be observed in a collection system or upstream of an advanced treatment facility. Enhancements in water and energy recovery are being implemented to make sure the water is made available at the lowest cost

Fit-for-purpose technology use. Traditional treatment trains with reverse osmosis (RO) are now being challenged by innovative trains that include ozone and granular activated carbon (GAC). Incorporation of desalination to expand the water portfolio is also part of this trend.

Incorporation of digital, connected solutions. Digital Water solutions and Industry 4.0 revolution that is driven by advanced sensor technologies, expanded and better use of data driven operation and controls decisions, system optimization capabilities that save water and energy, and more are bolstering trust in water systems.

This is truly the golden age for reuse. Advances in treatment equipment, improved monitoring and control, public and regulatory understanding for solutions, and economics are all converging to elevate reuse projects as a preferred means to enhance water resiliency.

Integrated resource management strategies also maximize water resources and resiliency. Integrated resource management looks at all water sources as a supply and available product. But it also extends beyond the One Water mindset. This adjustment in thinking reveals opportunities to extract resources that would otherwise be wasted, enhance water quality, and lower costs through cost-sharing opportunities. A reuse facility can help solve multiple problems, including expansion of drinking water supply and the need for improved wastewater effluent quality. Similarly, planning and development of water infrastructure that effectively considers multiple resources can yield multiple economic and other benefits. Holistic approaches to water management in combination with new technology allow cost effective resource management through tailored solutions.

Dr. Erdal is Black & Veatch’s Integrated Solutions and Capabilities Director, overseeing development of sustainable approaches through thoughtful integration of traditional approaches with system scale and data insights based solutions, such as Digital Water and One Water (Water Supply, Total Water Management & Reuse) efforts. She has worked on some of the largest infrastructure renewal planning and implementation programs including the City of San Diego’s $3B Pure Water Program and the $1B San Mateo CleanWater Program, Singapore PUB NEWater and DTSSI/ II programs that included IPR/DPR facilities, as well as the first sustainable city – Masdar City, statewide climate and sustainability programs such as for California, Arizona.
