The Village of Suamico automatically calculates a summer sewer credit for residential water customers in the third quarter (July through September) of each year. The credit is given to help offset the cost of water used, but not returned to the sewer system. An example of this type of usage would be lawn or garden watering. The sewer credit is figured on the difference between your actual third quarter water usage and the average water usage of your previous three quarters. If you do not have three full quarters of actual water usage, the standard average of 14,000 gallons per quarter is used. Additional information on the calculations may be obtained by calling our Village Office at (920) 434-2212 and asking for Utility Billing.
