1. A Water and Sewer Service Permit will be required for the following types of reconnections:
a. Services that have previously been disconnected. The permit is required regardless of if the service was disconnected on the public or private side.
b. Water services reconnected without a permit. The permit is required prior to DWSD turning the water on to the property.
c. Water services that are inactive due to connection to an abandoned main. Unoccupied houses and houses scheduled for demolition are not reconnected during new water main construction and will require a new water tap.
d. Active accounts that are only billing for stormwater.
e. Services for split parcels. If a parcel is split into multiple parcels, the parcel where the service is located becomes the service owner. The new parcels are required to make new taps.
2. Irrigation Services for Urban Farms will require a Water Service Permit through the above Water and/or Sewer Service Permit process. Go to the Water and Sewer Service Permit Engineering Review Request online form to obtain Permit Engineering approval prior to Water and Sewer Permit Application submittal for your Irrigation Service.
a. Irrigation Services are to be 1" services.
b. Meters are required to be in Wabash Boxes. DWSD does not provide or sell Wabash Boxes.
c. Either an Atmospheric Vacuum Breaker (AVB) or Pressure Vacuum Breaker (PVB) shall be utilized for backflow prevention. The AVB or PVB shall be located 6-inches above the highest piping point.
d. If chemicals are introduced into the irrigation system via a chemical feed pump, the portable piping must be protected by a Reduced Pressure Principle Backflow Assembly (RPZ) upstream of the chemical feed pump.
3. Submit the final site plans with a scope of work description indicating which sheets contain your civil site drawings related to water and/or sewer. These plan sheets should clearly highlight the connection points to the DWSD system(s) on the plans/drawings.
4. If your application for the building permit or fire suppression system is in process through BSEED ProjectDox, then BSEED will route your application to DWSD for review and approval within ProjectDox before you apply for an official DWSD permit.
5. A Water and Sewer Service Permit will not be required to turn on services that have been shut off at the stop box, but not disconnected. For more information about turning on a water service, visit the How Do I Turn On/Transfer/Turn off Water Service page.
Buildings with a lead water service line create an increased risk of exposure to lead from the drinking water. The drinking water from DWSD's system is safe; however, lead particles can dissolve into the water passing through a lead water service line. Lead can cause serious health and development problems, especially in developing fetuses and young children. If a property owner has work performed on their private lead water service line, DWSD recommends that the lead lines be replaced in full and not reconnected to the stop box. A permit applicant who reconnects a lead water service line does so at their own risk. Please contact DWSD Permitting for more information on a property's historical water service line records and how to determine if the property has a lead service line. Visit Michigan.gov/MILeadSafe for more information about sources of lead and what you can do to reduce your exposure.
