How is the sewer rate calculated?
A. The City of Cottage Grove does not have meters that measure the amount of sewage that enters the sewer system from individual residences. Therefore, your sewer rate is determined by the amount of water that comes into your house during your winter quarter billing cycle. We do this because we do not want to include water that is used to water lawns and gardens, or water that is used to fill swimming pools, since that water never enters the sewer system. If you would like to know exactly which dates are used, please contact our Utility Billing department at (651) 458-2831.
