The Dublin San Ramon Services District has begun construction on a system of purple pipes to bring reclaimed water to areas of western Dublin, hoping to alleviate some symptoms of a four-year drought.
The water retailer, which provides wastewater services to parts of Pleasanton, will add the pipes so residents and agencies can use recycled water, rather than drinkable potable water, for irrigation.
The pipes will be installed at about 40 locations west of Interstate 680. When complete, the district hopes the project will save 49 million gallons of water a year. The pipes will provide irrigation for parks, schools, government facilities, and commercial and multi-family properties, not single-home families, DSRSD spokeswoman Renee Olsen said.
Construction will cost $4.29 million and is part of a roughly $7.9 million project to extend recycled water pipelines to Santa Rita Jail and other Alameda County properties, she said.
She said the project is funded in part by a $2 million state grant from the California Department of Water Resources Integrated Regional Water Management Plan (IRWMP), funded through Proposition 84 -- legislation that authorized the state to sell bonds to fund water and flood control projects.
DSRSD will pay the remaining $5.9 million mostly through developer fees to reserve capacity in district water systems, but it is also receiving some funding through ratepayer funds, Olsen said.
The city of Pleasanton is also breaking ground on recycled water pipes. The city recently announced it will install 10 miles of purple pipes to distribute recycled water to more than 130 irrigation meters, which the city hopes will save 450 million gallons of drinking water.
Pleasanton received a $17 million low-interest loan to install the purple pipes, which will be repaid over the next 30 years by businesses that purchase the recycled water.
Pleasanton's construction is expected to last a year and could affect traffic in the short-term.
DSRSD will install 4.5 miles of purple pipes, including 3.1 miles in western Dublin, Olsen said. Construction in Dublin began in June and will continue through December.
While construction around schools was done during the summer to minimize impact to traffic, some roads will be impacted at some point over the next few months, including Amador Valley Boulevard from San Ramon Road to Penn Drive, San Ramon Road from Dublin Boulevard to Vomac Road, Dublin Boulevard from Silvergate Drive to San Ramon Road, Shannon Avenue, parts of Peppertree Road, parts of Juarez Lane, parts of Castilian Road and parts of Iglesia Drive.
Recycled water is treated wastewater that is safe for irrigation, but not for drinking. DSRSD has also provided recycled water for pick-up for individuals within its service area. Recycled water can be retrieved at the Pleasanton fill station at 7399 Johnson Drive and the Dublin fill station at Clark Ave. at the Dublin Safety Complex.
