Surface Water Management Credit Program

If you have a storm drainage system on your property, and the system is properly constructed and maintained, you may apply for a SWM utility charge credit. Participation in the credit program can reduce SWM utility service charges by as much as 85 percent.
Application and Recertification Process
To receive a reduction of SWM Utility charge, the applicant must:

  • Submit an application between Jan. 1 and Oct. 1 to receive credit for the following year. Applicants are encouraged to submit as early in the year as possible.
  • Submit approved as-constructed plans, calculations and the operations and maintenance manual for the site's drainage system. All three documents must be stamped and signed by a licensed engineer.
  • Certify that the system is constructed and functioning as designed. Recertification is due annually by the owner, and every fifth year by a licensed engineer. A certification notice will be sent to you in August. Recertification applications must be received no later than Oct. 1. If you do not receive your notice, please email or call (253) 798-2725.                       
  • Perform the required maintenance to keep the system functional, including periodic self inspections, keeping a maintenance log, and submitting an annual maintenance report upon request.
