About us

California Sub-Meters

Founded in 1991 as consultants for large water users, our first clients were the local community colleges and large condominium communities and we were successful at reducing their water and sewer bills. CSM is the leader in providing private water sub-metering systems and water management services for residential homeowners for 30 years!

Offering Peace of Mind Through Conservation

We’ve always felt very strongly about water conservation and our solution became Sub-Metering. Sub-Metering helps to locate leaks and excessive usage which in turn offers peace of mind. Residents pay only for the water they use, and when they see a bill they are more inclined to conserve. Through submetering we are now billing customers for their water usage and promoting conservation throughout California and other US states!
