Deduct Meter Program

A 5/8" Deduct MeterMany times citizens of Manchester will use the water obtained from the Manchester Water Works to fill their pools, wash their cars, and water their lawns and gardens. This water typically does not enter the City sewer system for subsequent treatment at the City’s Wastewater Treatment Facility.

Because Manchester sewer bills are based on water usage, the deduct meter program was established to provide a credit for water that does not enter the sewer system.   This program is available to all property owners, however, for non-residential commercial/industrial properties, the program is limited to lawn irrigation usage.

This separate deduct meter is purchased by the property owner at his/her own expense to measure outside water usage.  The meter reading consumption from the deduct meter is then deducted from the Manchester Water Works meter reading consumption, to determine the Sewer Usage Charge.
