What Is Sub-Metering?

Sub-metering is the placement of individual meters behind the city master meters. These meters are installed on the water line that services each individual unit.

Why Sub-Meter?

Sub-meters track individual water consumption. Pay only for the water you use, not your neighbors. Due to increasing rates, water-wasting leaks, and excessive usage, water management has become a significant challenge. Sub-Metering is a solution to manage water and sewer costs by offering equitable distribution of costs along with the peace of mind.
