Construction starts on purple pipes in Dublin

DSRSD adding recycled water pipes for irrigation to save drinking water during drought

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.

The city of Pleasanton will provide updates to its recycled water project at

Purple Pipes....

I'd like it if the reporter had added specificity about the where and how of connecting the pipes. Where, is west of 580, while "connected to what?" is the missing piece. There is an opportunity for describing much more about how this water conservation infrastructure will actually be put into place and operated.

My kudos to Anton Hacienda, the new apartment complex on W. Las Positas, near the northwest corner of W. Las Positas and Stoneridge Dr. They must be the first customers of the purple pipes. I say this because I drive by there very often, and the grass is very long, lush, and green, and I have seen the water sprinklers on during the middle of the day. So this must be reclaimed water, right? Please tell me, in the middle of this drought, with the grass in many other places of the business park very brown, that Anton Hacienda is using reclaimed water. Please tell me this is true. Please someone at the city or the Weekly please tell me that they are not carelessly putting our water into their landscaping - which could easily have been drought-tolerant landscaping - but instead are using reclaimed water. I doubt this to be the case, but someone please tell me I'm wrong.

Unless something has changed, apartment and school landscaping were excluded from the recycling program. Only business landscaping and the sports park grounds were to be connected with the purple pipes via special meter hook-ups.
