Document Description
The State Water Resources Control Board (State Water Board) is the Lead Agency for the Project. The State Water Board’s Drinking Water State Revolving Fund (SRF) Program is financing the Project. The Project includes two construction components: One portion involves sliplining approximately 200 linear feet of the existing transmission main from the existing wells to a location just north of the northern boundary of the United States Forest Service (USFS) property. The sliplining method will involve pulling a carrier pipe through the existing transmission main from an insertion pit to a receiving pit. These pits are anticipated to measure eight feet in length by eight feet in width. The pits will be excavated and located within the Largo Vista Road right-of-way. The purpose of sliplining is to minimize the impacts to the USFS property and to the drainage located in this area. The other portion involves the replacement of approximately 7,600 linear feet of four-inch diameter high-density polyethylene pipeline from just north of the USFS property (the end of the sliplining portion) to the transmission-distribution system transition point. This portion may be either replaced or sliplined. The existing pipeline will be abandoned in place.
