PICO RIVERA — Work on a multiagency storm water and recycled water pipeline construction project is under way at the intersection of Paramount Boulevard and Mines Avenue, a city representative said.
The project, which is being supervised by the county Department of Public Works, is a cooperative water conservation effort between the county public works, Pico Rivera, the County Flood Control District, the Southern California Water Replenishment District and the Central Basin Municipal Water District.
To reduce traffic impact, work at the intersection will take place only from 9 a.m. to 3 p.m., the representative said.
In order to save money and reduce inconvenience to the public, the project will install two separate pipelines simultaneously in a single trench.
Completion of the project is expected next September.
Access to homes will not be restricted during construction. Work will generally occur on weekdays, the representative said.
The first of the two pipelines, the San Gabriel River Coastal Spreading Grounds Pump Station Pipeline, is a 78-inch concrete pipe connecting the San Gabriel River and Rio Hondo Spreading Grounds.
The spreading grounds are used by the Water Replenishment District to collect storm water runoff, imported water and highly treated recycled water that then percolates from the surface into the aquifers below ground, becoming what is known as groundwater.
Having the ability to move water between the two spreading facilities will allow the district to ensure as much water as possible is captured and used to replenish the groundwater supplies.
By increasing the amount of usable groundwater, the district can reduce the amount of water that needs to be imported to meet the local demand for drinking water, the representative said.
The second line, consisting of a much-smaller 8-inch iron pipe, will be used to transport recycled water for irrigating schools, parks, medians and other public landscaping.
The pipe will eventually tie into Central Basin’s Southeast Water Reliability Project, a 12-mile long pipeline extending from Pico Rivera through Montebello and southeast Los Angeles County that will move recycled water throughout the region.
Bringing recycled water into the community is the single most effective way to conserve the limited supply of drinking water. It is also a way to control overall water costs because recycled water is less expensive to purchase, the representative said.
A Los Angeles County inspector will be on site during construction and may be contacted at (626) 458-3122 to address any concerns regarding the work.
