Castaic Lake Water Authority/MWD – Santa Clara Valley Foothills Pipeline Turnout

Projectline provided electrical and instrumentation design services for a new MWD turnout to the Castaic Lake Water Agency as a subconsultant to Kennedy Jenks. The new turnout from the 200 inch MWD Foothill Feeder includes a 48” isolation valve and magnetic flow meter in separate underground vaults. A new electrical supply is needed to provide the turnout loads. The flow meter is connected to a new AMR cabinet which connects by phone modem to MWD’s monitoring center. The local RTU is also connected to CLWA’s existing PLC cabinet close by. In a related assignment, working directly for MWD, ProjectLine assisted with evaluation of alternatives to divert dewatering discharges from the Foothill Feeder from the Santa Clara River. The evaluation was undertaken to mitigate impacts to an endangered fish, the Unarmored Threespine Stickleback. Concepts were developed for diversion of the majority of the 50 million gallons of dewatering water from the area of concern, however, MWD determined biological monitoring and relocation protection of the fish to be more effective than water diversion.
