Document Description
Kernvale Mutual Water Company (KMWC) is a community water system (No. 1500364) with 22 connections serving approximately 52 residents in the unincorporated community of Lake Isabella in Kern County. The system currently receives water through a groundwater well and has exceeded the United States Environmental Protection Agency (USEPA) maximum contaminant levels (MCLs) for arsenic and uranium. Erkine Creek Water Company (ECWC) is a nearby water system and has agreed to allow KMWC to consolidate services for the 52 residents. ECWC has been approved by the California Department of Public Health (CDPH) to act on behalf of KMWC for the Project. The Project purpose is to consolidate KMWC into ECWC by permanently connecting and upgrading the existing water systems to provide more reliable water service and provide safe drinking water that meets USEPA MCLs and California Code of Regulations Title 22 standards. The Project will be built out in two phases as described below: Phase I: • Water Storage Tank - A new 200,000-gallon water storage tank would be instated on an existing gravel pad to replace a smaller existing 120,000-gallon tank located at the east end of Webb Avenue. The new tank would be approximately 48-feet across and 24-feet tall. • Distribution Water Pipeline – Installation of approximately 3,550 feet of 8-inch diameter with 280 feet of 12-inch PVC pipe. The new waterline would travel from the new water tank, over the Borel Canal and east onto School District property, then run north along the Borel Canal, Mountain View Road, turn west between two existing residential homes and then continue north along the back of the remaining homes until reaching Erskine Creek Road, turn west and connect to the existing ECWC pipeline on Erskine Creek Road near Edna Avenue. • Borel Canal Crossing – Canal crossings would be accomplished by installing a 8-inch pipeline within a 16-inch casing and attaching the casing at two bridge locations: one at the pedestrian bridge located between the ECWC tank property and the schools; and the other would be attached to the Erskine Creek Road crossing. • Fire Hydrants – Fire hydrants would be placed along Mountain View Road. • Hydropneumatics Tank – The installation of a 5,000-gallon hydropneumatics tank would be placed at the east side of the ECWC property. • Associated infrastructure – Associated infrastructure components include water meters, fittings, connections, valve boxes, air release valves, shut-off valves, and flushing valves. • Asphalt and Concrete – The new pipeline would be placed in Mountain View Road and Erskine Creek Road right-of-way and the roads would be regraded and repaved to pre-construction conditions. • Vegetation Removal – Minimal vegetation removal may be required and would consists of low-lying grasses and vegetation. One cottonwood tree may also be removed located near the Boral Canal crossing and some trimming of cottonwood trees limbs may also be required. Phase II: • Pipeline - consists of an additional water line to connect at the canal crossing and run east between Kern Valley High School and Woodrow W Wallace Elementary/Middle School to an existing water tank located across Erskine Creek Road. The existing temporary waterline would be abandoned in place. • Pump Station – One new pump station may be installed in the future on ECWC property located at the end of Webb Avenue. The booster pump station would be for the north/ shopping center zone and the school zone areas.
