Operation and maintenance manual

Program implementation details are outlined in the governing administrative codes and statutes: §§ 281.58 and 281.59, Wis. Stat., and chs. NR 162, Wis. Adm. Code.

If a municipality is receiving a loan from the Clean Water Fund Program (CWFP), it must submit for review an operation and maintenance (O&M) manual for its wastewater treatment facility and/or collection system. If the municipality already has an approved O&M manual, it can meet this requirement by submitting to DNR an addendum to the original manual.

The following topics must be addressed in the O&M manual:

  • general information;
  • staffing;
  • records and recordkeeping;
  • laboratory;
  • safety;
  • utility systems;
  • a description of the process, operations, and controls;
  • maintenance;
  • sludge management; and
  • manufacturer's information.

Send a copy of the O&M manual or addendum to the municipality's local DNR watershed/basin engineer. Submit a Wastewater Treatment Facility O&M Manual Certification Checklist Form 8700-311 and/or a Wastewater Collection System O&M Manual Certification Checklist Form 8700-310 to the DNR loan project manager.

The consulting engineer should complete the checklist; both the engineer and the municipality's authorized representative shall certify by signature that the O&M manual meets or exceeds the requirements of the department. The DNR loan project manager will review the O&M Manual Certification Checklist for completeness. An acceptance letter will not be returned to the community or engineer.
