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. The work at the Snowflower and Woodland Condos is meter pit replacements. The existing infrastructure is aged and due for replacement to meet current standards. This will assist maintenance workers in addressing potential future issues in these condo complexes. The work on the southern Frontage road along Highway 203 is extension of an existing sewer main. A sewer main was previously constructed in the Frontage Road for local businesses to connect to. This main will be extended an estimated 87 feet. This extension will allow all businesses in the cluster to be serviced by the Frontage road sewer main rather than the Highway 203 main. This will allow for maintenance to be performed off of the Highway, providing safety of maintenance workers and the public.
