Sound Planning is the Foundation of Reliable Services
Environmental and political challenges are decreasing the reliability of the State Water Project, which supplies 80 percent of our drinking water. DSRSD began diversifying its water supplies in the 1990s through efficiency and water recycling. Current efforts focus on further diversification, including studying the feasibility of potable reuse and exploring options for desalination with other Bay Area water agencies.
In addition to ensuring reliable water supplies, the District must ensure that pipes, pumps, treatment plants, and sewer systems are proactively maintained and upgraded. Fees and rates provide for current operations and infrastructure maintenance, capital investments, and a highly-qualified and trained workforce.
The stories below describe some of the ways DSRSD is planning and investing for the future. Click Archived News for items more than six months old.
Purple Pipes Saved Water during Drought
|The Central Dublin project brought recycled water pipes to Kolb Park in 2013, allowing the City of Dublin to keep the park green during the drought that followed.
Situation: Recycled water is key to the district’s efforts to maintain and increase water reliability by diversifying the water supply. In newer areas of Dublin, parks, schools, commercial properties and common areas of many HOA-managed developments are designed and built with recycled water systems in place. Established neighborhoods must be retrofitted to replace potable water irrigation with recycled water, a more expensive, disruptive, and time-consuming process.
Solution: Beginning in 2012, DSRSD extended recycled water pipelines into central Dublin to convert irrigation at four parks and three schools. As the drought intensified in 2014 and 2015, the district expedited conversions of 33 large potable irrigation accounts in central and eastern Dublin and extended “purple” pipes across Interstate 680 to connect another 35 sites in western Dublin.
Together these projects are saving nearly 240 million gallons of potable water every year. A combination of developer and ratepayer funds, plus $3.5 million in state and federal grants, paid the $15 million costs. A California Proposition 84 grant provided more than $3 million of the grant funding; federal WaterSmart and Title XVI grants provided the rest.
Central Dublin Project
The district had connected parks and schools in Dublin’s oldest central neighborhoods to the recycled water distribution system a year before a drought emergency was declared in the Tri-Valley. Beginning in 2012, contractors installed 8,200 feet of new pipes in the residential area near Amador Valley Boulevard and Davona Drive and connected them to the main recycled water supply line that runs along the Iron Horse Trail. The project also involved boring under South San Ramon Creek in two places and retrofitting existing irrigation systems at the schools and parks.
Decades of investment in recycled water infrastructure made it practical to convert 33 irrigation accounts to recycled water in 2014 and early 2015 as the drought worsened. This included the 45-acre Amador Lakes Apartments, the district’s largest potable water irrigator at the time. The district also extended pipelines to Alameda County’s Santa Rita Jail and other nearby government offices.
|Contractors dig a trench on San Ramon Road in 2015 for new pipelines that will deliver recycled water to City of Dublin's Shannon Park and other large irrigation sites west of Interstate 680.
Western Dublin Project
The western Dublin project added another 19,000 feet of purple pipelines during the height of the drought emergency in 2015. Starting where the central Dublin pipeline ended, the contractor crossed under the freeway at Amador Valley Blvd. and branched out to 35 large irrigation sites along San Ramon Road, including schools, parks, shopping centers, and office buildings. Pipeline construction was complete by December and irrigation systems were converted in time for the summer 2016 watering season.
