California Sub-Meters started in 1991 as consultants for large water users. Our first clients were the local community college, large condominium communities and apartment complexes. We were successful at reducing their water and sewer bill.

We always felt very strongly the need for water conservation. Our solution became sub-metering. Sub-Metering is installing individual meters at each unit (behind the city master meter) which helps to locate leaks and excessive usage. Residents pay only for the water they use. We are now billing customers for their water usage and promoting conservation throughout the state of California.
