Upper Main Ditch Piping Will Protect Water Quality
The Upper Main Ditch Piping Project includes piping a three-mile section of water supply ditch in Pollock Pines with a buried pipeline. The ditch conveys up to 15,080 acre-feet of raw water each year from Forebay Reservoir to EID’s Reservoir 1 Water Treatment Plant in Pollock Pines.The water that travels through this important district facility can be used to serve our customers in Pollock Pines, Placerville, Cameron Park, and El Dorado Hills. Water sold to the City of Placerville also travels though the ditch.
Piping this section of open earthen ditch will minimize water loss and add as much as 1,300 acre-feet of usable supply each year that would otherwise be lost to seepage. The pipe will also protect water quality and help save money on maintenance and treatment processes.
Over the years many things have ended up at the headworks to the Reservoir 1 plant. These include multiple mattresses thrown into the ditch, many car tires, and a variety of toys.
Dead skunks also show up in the ditch from time to time, as well as garbage discarded from fast food restaurants, blankets, and a variety of clothing items. Yard waste and other household waste can and does end up in the ditch.
“Piping this important artery in EID’s water system will protect drinking water quality by eliminating the risks posed by intentional or unintentional contamination,” said EID General Manager Jim Abercrombie. “This adds important security to a section of EID’s water system that benefits a significant portion of our customers.”
In the short term, piping the ditch has the additional potential to increase hydroelectric revenue by approximately $200,000 per year in normal water years and will help pay for the project.
A draft environmental impact report (EIR) is expected to be released in February of 2017 with a period for public review and comment. After that public review period is complete, a final EIR would be produced later in the spring.
