As of noon, April 26, 2008 Flume #14 on the Highland Canal System, one of the facilities that supplies raw water to the Chalk Bluff Water Treatment Plant in northwest Reno, was damaged in the earthquake just before midnight on Friday evening.
The plant is owned and operated by Truckee Meadows Water Authority (TMWA). TMWA supplies high-quality drinking water to most of the residents and businesses in Reno, Sparks and Washoe County. Chalk Bluff is the largest water treatment plant in the water system.
With the exception of irrigation customers that receive water directly from the Highland Canal, water service to TMWA customers IS NOT affected due alternate sources of supply to the water system and treatment plants. No extraordinary conservation measures are needed and customers can use water as normal at this time.
Due to redundancy, TMWA’s water system is meeting all demands. Currently, the Chalk Bluff Water Treatment Plant is in service and operating at 75% of normal capacity. The rest of the community’s water needs can be met by TMWA’s wells and the Glendale Water Treatment Plant, so that customers are not affected at this time.
TMWA had a specific emergency plan in place, knowing that facilities in the Mogul area were vulnerable to this current series of earthquakes. Crews were activated immediately after last night’s earthquake and worked throughout the night to isolate the affected flume and assess damage. It is not known, at present, when the flume will be back in service.
There was no damage reported to homes in the area.
