Optimizing Wellfield Operations for the East Valley Water District

The East Valley Water District (EVWD) serves about 90,000 customers in San Bernardino County. As part of a 10-year, $4M performance contract, the EVWD is receiving assistance from Honeywell to improve its water distribution systems and reduce utility costs. This goal will be achieved through a combined energy conservation / automated demand-response program; because Honeywell is financing the program from annual energy-savings performance, the EVWD will not be required to provide upfront capital for system upgrades. One important approach for reducing energy costs is optimizing wellfield operations.
