Sewer volume charges for metered residential customers are based on actual metered water flows for the first, second and fourth calendar quarters. The third calendar quarter’s sewer volume charge (summer quarter) is based on the actual metered water flow for said quarter, or the calculated average of the three previous quarters, using whichever is less. A minimum calculated average of 8,000 gallons is required for the average to be used for the third quarter. This credit will be given automatically to all residential customers.
Residential customers who have extensive outdoor water usage in early spring, late summer or fall may wish to install a sewer-deduct meter at their cost to measure “non-sewer” usage. Customers wishing to do this must call the Accounting Department at (262) 796-6661 or Finance Email to obtain an application form. Once the deduct meter is installed and inspected, sewer volume charges will be based on the consumption from the primary meter less the consumption from the deduct meter and not the calculated average as outlined above.
