General Sewer Billing Information


Effective June 1, 2012, the Warwick Sewer Authority (WSA) will no longer allow adjustments to sewer usage bills for the filling of swimming pools. Other adjustments to sewer usage bills (e.g., underground water leak, frozen pipes, etc.) will only be considered with proper documentation. These include, but are not limited to, repair bills, insurance claims, and work orders from the Warwick Water Division.

Sewer usage charges are based on One Hundred Percent (100%) of water consumption with a factor of Fifteen Percent (15%) for residential rates to account for water not returned to WSA for treatment.

WSA recommends that anyone who uses a lot of outside water should consider purchasing a deduct meter from the Warwick Water Division.

Please call (401) 738-2008 to purchase a deduct meter. If you are serviced by Kent County Water Authority, only, please call (401) 468-4710 for information on deduct meters.
