Steps For Inflow and Infiltration Inspection
1. Submit Application and Pay Fee
The application fee is $250 for residential properties and $750 (per building) for commercial or multi-unit buildings.
- By Mail or In Person: You can submit your application and fee paid by check via mail or in person at the Public Works Department in City Hall.
- Online: Applications may also be submitted online and the fee paid by credit card.
- Please note, water must be available at the property for the inspection to be completed.
2. Schedule Inspection
Call 763-593-8030 between 8 am and 4 pm to schedule an inspection. Provide permit number, if application was submitted online, and at least 24-hour advance notice.
- The appointment will take approximately one and one-half hours for residential properties and a minimum of three hours for commercial or multi-unit properties.
- A responsible adult must be present at all times during the inspection.
3. Prepare For Inspection
Before the inspection, the property owner must do the following:
- Make sure the water is turned on at the property. The inspection cannot be completed without water.
- Locate the four-inch diameter vertical wastewater pipe that runs down through the basement from a bathroom above. This pipe will have an access point called a cleanout. Cleanouts are usually located on the pipe between approximately six inches and two feet from the basement floor.
- Make sure the cleanout cover is in working condition before the inspection can be performed. To ensure the cleanout cover is in working condition, the cover should be loosened and removed, then reinstalled so that a watertight seal is achieved.
- Make sure the floor area around the cleanout is clear (a five-foot radius).
- If there is a cleanout cover located on the floor in the basement, this cover should be in working condition. The inspector may need to gain access to any cleanout covers located in the basement floor, but the inspection cannot be performed through this type of cleanout. Even if the property owner has a cleanout cover located in the floor that is easily accessible and used for sewer cleaning, the inspector must use the cleanout in the vertical four-inch diameter wastewater pipe.
- If you have a sump pump, make sure it is accessible for inspection.
- Make sure the sump pump discharge piping is visible.
4. Wait For Review
Allow up to five working days for the City to review the inspection video and issue a compliance certificate or correction notice.
If problems are found
- You will receive a correction notice from the City identifying the problem(s). City Code requires repairs to be completed within 180 days. You will need to contact the Inspections Department (763-593-8090) for the necessary permits to correct the problems (plumbing, etc).
- Correct the problems (getting the correct inspections for the work done along the way) and call the Public Works Department to schedule another I/I inspection.
- If your property is then found compliant, you will receive your compliance certificate. If the property is not compliant after two inspections, an additional application fee ($250 for residential properties; $750 for commercial properties) may be charged.
While some cities have been successful at reducing I/I, the regional problem is still significant and more participation is necessary. To enforce this, starting in 2013 MCES will implement a wastewater demand charge for communities with excessive I/I, including those with reduction programs. This means a city could get assessed a surcharge if it were to exceed sanitary sewer flow levels during a major rain storm, even if it had previously shown reduced flow rates through I/I mitigation.
