Progress Continues on Major Pipeline Relining Project

Construction on a major pipeline relining project is progressing in La Mesa, with steel liners being installed through portals that provide underground access to the large-diameter pipe.

The Lake Murray to Sweetwater Reservoir Pipeline 3 Relining Project will rehabilitate approximately 4 miles of the Water Authority's 66-inch and 69-inch diameter pipe between Lake Murray and Sweetwater Reservoir, extending the pipeline's service life and ensuring continued water system reliability. Construction began in September and is anticipated to continue through summer 2018.

Once the steel liners are installed, the segments are welded along the seams and joints. Later, the space between the old pipe and the new liners is filled with grout, and mortar is applied to the inside of the liners to prevent corrosion.

Free Manure Management and Composting Workshop in Lakeside   

The Solana Center for Environmental Innovation is hosting a free manure management and composting workshop on Saturday, Dec. 9, from 10 a.m. to 12 p.m. at the Wells Family Ranch in Lakeside.

WaterWorld published an article on Nov. 15 about how water utilities in Southern California are embracing water reuse in response to drought, dwindling supply, and the cost of importing supplies.

The article featured Pure Water San Diego, which is expected to provide one-third of the City of San Diego's water supply by 2035.

"Even though our demonstration facility was designed to run from 2011-2012 for the purposes of state reporting, we've never stopped operating and that has been an important tool as a way to provide awareness and outreach to our customers," Brent Eidson, the city's external affairs deputy director, told WaterWorld.
