The Sewer Submeter Program was instituted to make allowances for commercial business customers who use water that doesn’t enter the sanitary sewer. Water used for irrigation, delivery of water to ships, and water used in manufactured goods or products are all examples of situations where a submeter may be installed.
Customers are responsible for the purchase, installation, maintenance and accuracy of their own sewer submeters, equipment and appurtenances.
To receive the sewer deduction from your account, customers must install and maintain submeters that are authorized by Seattle Public Utilities.
Most customers will only be authorized to install deduct meters to eliminate sewer charges for water that doesn’t enter the sanitary sewer system. Example: irrigation, water used in products and makeup feed water for cooling tower evaporation. When receiving a deduction on a cooling tower or other such equipment where there is discharge to the sewer, a charge meter is required on those drain lines.
