Celebrating the Central Dublin Recycled Water Project

I was pleased to attend the Central Dublin Recycled Water Project Celebration today at Dublin's Kolb Park hosted by the Dublin San Ramon Services District. The Central Dublin Project was DSRSD’s first major retrofit of older facilities, bringing a supply of recycled water to four schools and three parks. Contractors installed 1.5 miles of recycled water distribution pipes under residential streets last fall and converted sprinkler systems at the parks and schools in early 2013. The Central Dublin Project is projected to distribute an additional 44.3 million gallons of recycled water per year, saving enough potable water to serve another 433 households. Zone 7 was proud to partner with DSRSD on this project, providing $39,000 from state water conservation grants to retrofit the sprinkler systems at the schools. A fact sheet from DSRSD with more information about the project and its benefits is available here.

Recycled water is wastewater that has been cleaned through primary, secondary, and tertiary treatment.  The process follows strict standards set by the California Department of Public Health, including disinfection to remove pathogens. According to these standards, tertiary-treated recycled water is safe for all human contact except drinking. Recycled water distribution systems are completely separate from potable water systems and are colored purple for easy identification. DSRSD requires new developments to be plumbed, from the start, for recycled water irrigation at parks, schools, golf courses, commercial areas, and other large landscapes. Older neighborhoods in the DSRSD service area are being retrofitted as funding becomes available.
