The city of Pleasanton has completed a major milestone in its purple pipes project, which aims to bring approximately 450 million gallons of recycled water a year to three facilities throughout the city.
Construction crews have completed installing the backbones of the piping system that will deliver the recycled water to the Ken Mercer Sports Park, located at 5800 Parkside Drive.
"This whole public works project is quite an undertaking," said Steve Kirkpatrick, director of engineering.
"But the directional boring and subsequent placement of this particular pipe, 1,498 feet of pipeline buried at a depth of 85 feet underground, was a major milestone."
Once the project is complete, the piping system will also deliver recycled water to Hacienda Business Park as well as the Tennis and Community Park.
The entire project will install about 10 miles of a new purple pipeline that will deliver recycled water for irrigation purposes to the three facilities.
The color purple is used to indicate that recycled water is
being used, Kirkpatrick said.
Upon completion, the project will save the city about 10% of its drinking water, he added.
The project is being funded by a $12 million low-interest loan along with a $5 million grant provided by the state to encourage the use of recycled water.
