Commercial Tapping Procedures

Sanitary Sewer Tapper Information

To obtain a tapper license with the Northwestern Water and Sewer District (“District”), the District requires that you submit an application that includes a statement of your company’s experience, along with several references that the District may call

Upon submission and approval of the above-mentioned, you will also need to take and pass the District’s licensing examination. With an understanding of the District’s rules and regulations

If the above requirements are satisfactory, before the license can be issued to your company, the following must be submitted:

  • A bond for $25,000 for the current year with the Northwestern Water and Sewer District as the obligee.
  • A certificate of general liability insurance showing the Northwestern Water and Sewer District as the Certificate Holder, for the current year.
  • An application fee of $100 made payable to the Northwestern Water and Sewer District.

The sewer tapper license expires at the end of each calendar year. Therefore, the bond (or continuation certificate) and renewal fee of $25 will be required to renew at the beginning of the year to continue licensed status. Depending on when your company’s certificate of liability insurance expires, you will be required to provide the District an updated form to continue your licensed status as well.

If you have any technical questions, please call Tom Stalter, Director of Engineering, at (877) 354-9090, extension 174 or you may email Tom.
