The Nevada Irrigation District activated an emergency pumping system Thursday to restore water flows to the Cascade Canal and two of Nevada County’s largest water treatment plants.
NID Maintenance Manager Brian Powell said five high-pressure pumps have been placed along the DS Canal east of Nevada City to pump water to the higher elevation Cascade Canal, where it can reach more customers.
The emergency pumps were ordered and rented following the Nov. 21-22 wind storm that caused significant damage to the South Yuba Canal in Bear Valley, cutting flows of water from the mountains into NID’s Cascade system.
The damaged canal is owned and operated by the Pacific Gas and Electric Company, which is repairing the damages. PG&E is estimating repairs will be complete by Dec. 21, weather permitting.
NID Water Operations Manager Chip Close said Friday the temporary pumps will run 24 hours a day through Monday to replenish emergency storage in local reservoirs, which NID had relied upon since the outage began.
Conditions permitting, the district plans to cut back to daytime pumping next week. Close said this would provide some relief from the pumping noise in areas off Pasquale Road near Siphon Lane and across the canyon in the Willow Valley and Scotts Valley road areas.
“We would like to thank residents and all of our customers for their patience and understanding during this emergency situation,” he said.
NID’s Cascade Canal is the main supply for two of NID’s largest treatment plants, the Elizabeth L. George Water Treatment Plant on Banner Mountain and the Loma Rica Water Treatment Plant near the Nevada County Air Park.
District officials estimated the pump rental costs to be $50,000 or more, depending upon how long the pumps are needed.
