Residential Sewer Adjustment Policy - Clinton Utilities Board

CUB automatically adjusts residential sewer bills during the summer period (meters read May 1 – November 30) to compensate for watering your lawn, filling your swimming pool, etc. This approach is based on the assumption that during the summer period, no more water will be entering the sewer system than the peak level established in the previous winter period (meters read December 1 – April 30). The maximum sewer charge set forth herein is not applicable unless a residential customer has maintained water service at the metered location continuously during the preceding winter period. Upon customer request, and on a case by case basis, CUB will evaluate sewer adjustments for the periods that occur just before and just beyond the summer period but adhere to the intent of the policy.

Each household’s highest monthly water usage during the winter period becomes its Winter Peak Usage. During the summer period, if a month’s usage is higher than the Winter Peak Usage, the sewer charge for that month is calculated using the Winter Peak Usage instead. All adjustments are made using the current rates in effect.
