Document Description
This project is spread over different locations with different goals for each. The first three neighborhoods mentioned, the Trails, Snowcreek Crest, and Juniper Ridge are lateral replacements. Aging water laterals will be replaced with higher quality pipe of similar size. This project will reduce water losses from leaks or bursting pipe and will benefit the community of Mammoth Lakes by increasing water supply reliability through reduction of losses. The work at the intersection of Fairway Drive and Old Mammoth Road will install a new gate valve into the existing water line. This will assist personnel in performing recycled water cross connection tests at Snowcreek Golf Course. This new gate valve will further the ability to isolate parts of the water system, limiting impacts to other customers when the golf course performs their mandated tests.
