KSN has been assisting the EBRPD since 2016 in identifying improvements to the Del Valle Regional Park water system, including repair and replacement of aging distribution piping and improvements to the water treatment plant. Following a comprehensive study in 2016, KSN is now assisting the District with pilot studies and design of improvements. The scope of this current project includes evaluation of the water treatment plant operational changes including, chemical dosing, bench and scale jar testing, plant-scale testing to control formation of disinfection byproducts. Based on this testing, improvements to the water treatment plant and distribution system have been proposed and will be designed by KSN, including enhanced coagulation, GAC polishing for TOC removal, chlorination, and distribution system improvements.
