Specifications include, but are not limited to: replace the connection between the District’s two largest drinking water treatment plant facilities that, together, provide two-thirds of the District’s water supply. The Project would enable the District to efficiently convey drinking water sourced from its existing supplies at Jenkinson Lake and the South Fork American River watershed to areas throughout the District’s service area. The Sly Park Intertie (SPI) is an existing 22- to 24-inch diameter steel pipeline, approximately 4.5 miles in length, which extends between the District’s Reservoir 1 Water Treatment Plant (Reservoir 1) and Reservoir A Water Treatment Plant (Reservoir A), and continues to the Sly Park Hills Tank.
