Understanding Your Wastewater Charges

KUB is committed to providing you with the information you need to understand your wastewater charges. Here are some of the facts we believe you should know:
  • Wastewater is not metered; wastewater charges are based on the customer’s water usage.
  • Wastewater rates are higher than water rates because it is more expensive to collect and treat wastewater than to purify and deliver drinking water.
  • Wastewater is billed monthly.
  • Wastewater rates are set by the KUB Board.
  • Wastewater rates reflect the cost of constructing, operating, and maintaining the wastewater collection system and treatment plants.

Sewer Improvement or Contribution In Aid of Construction Charge

If you are a residential KUB wastewater customer, your sewer bill may include a sewer improvement or Contribution In Aid of Construction (CIAC) charge in addition to a user charge.

The sewer improvement charge and the CIAC charge help pay for major facility expansions and improvements to serve you. The user charge funds remaining capital costs and helps operate and maintain KUB’s four wastewater treatment plants and more than 1200 miles of sewer lines. The user charge also pays for engineering and laboratory services to ensure that discharged water meets all state and federal standards.

Commercial and industrial customers may pay an additional charge for extra-strength wastes. This puts the financial burden of treating difficult industrial wastes on the businesses that generate them, not on residential customers.
