WALNUT CREEK, CA, March 21, 2013 -- Carollo Engineers, a California-based, water-focused consulting engineering firm, announced its recent pledge of $150,000 toward a new Direct Potable Reuse (DPR) research initiative, led by the WateReuse Research Foundation (WRRF). Since July of 2012, the WRRF has raised more than $2.7 million toward the California DPR Initiative, which exists to help California meet its legislative and state-mandated DPR initiatives by 2016.
DPR is a new approach to potable reuse. Indirect Potable Reuse (IPR), through augmentation of aquifers and surface water supplies, has been successfully implemented for more than 30 years. With the support of the industry, WRRF has researched treatment and water management approaches to protect the environment and public health when implementing IPR. Further, Carollo has investigated the use of membranes for trace pollutant removal (WRRF 06-019), the use of advanced oxidation processes to destroy pathogens and EDCs (WRRF 02-009), and the use of soil aquifer treatment (SAT) to remove pathogens (WRRF 10-10).
Though IPR is a viable and safe method for potable reuse, it has large cost impacts and implementation issues. Recently the industry has begun examining DPR -- which is the treatment and reuse of water for potable use without the use of an environmental buffer such as a groundwater basin or lake. WRRF is already at the forefront of this research initiative, with several DPR projects exploring how to properly modify IPR treatment and monitor approaches to deem DPR equally safe and reliable.
"With WRRF’s multi-million dollar research agenda on track to characterize DPR issues and treatment needs, Carollo is proud to be a partner on such a vital industry initiative. We look forward to contributing to the safe, affordable, and reliable implementation of DPR to help address California’s water resource needs," said Andrew Salveson, Water Reuse Chief Technologist and Associate Vice President with Carollo Engineers.
