OTWMD Active Maintenance Properties Weekends and Holidays Service Call Checklist

  1. Property owners should contact a septic pumper/maintainer and have their septic tanks pumped. Do not replace/fix anything else at this time.
  2. Property owner should contact the District Office the next open business day to discuss the service call and inform the district of the contractor that pumped the septic tanks.
  3. Property owner should provide a copy of the bill from the Septic Pumping Company to the OTWMD for reimbursement of the pumping cost. This reimbursement will happen at the next Monthly Board Meeting for the district. These meetings are held the second Wednesday of each month.
  4. The district will address the issue/problem that caused the service call during the work week. For example, replacing the pump in the lift station. If the issue is in the sewer line between the septic tank and dwelling this is still the responsibility of the homeowner to take care of. The district covers anything from the inlet of the septic tank through the drainfield. The only exceptions to this are freeze ups in the winter months and homeowner negligence. 
  5. Property owners should contact the District Office during business hours for any questions or concerns about your septic system The district office number is 218-548-7400 and the district email is ottertailwatermanagement@outlook.com.
  6. Only properties on the OTWMD Active Maintenance Program will receive reimbursement for the pumping of the septic tanks. All OTWMD Passive Maintenance Program properties are still the responsibility of the property owner to take care of.
