After conducting site visits in September 2023, the City will split the proposed sanitary sewer lining project into three phases. The figure (view map) shows the project groupings.
- Group 1 (2024): Project Areas 1-7, 12, 13, 15, and 19
- Group 2 (Future): Project Areas 8, 9,16, 17, 18, and 20
- Group 3 (Future): Project Areas 10, 11
Group 1 construction is proposed to begin in November 2024; Groups 2 & 3 will be part of a future sanitary sewer lining project.
Right of Entry Documents:
Access to sanitary manholes and the sewer alignment will be required to complete the work, and because these are located between the homes and the lake in many cases, Right of Entry agreements are required between homeowners and the City. The Right of Entry documents were mailed out to residents in Project Group 1 on February 27, 2024.
Please read, sign, and return to the City of Prior Lake using the provided return envelope no later than March 22, 2024.
When filling out your Right of Entry Document, please include the following on page 2:
Project Benefits
- The timing of this project is critical for preserving the integrity of the sanitary infrastructure and reducing inflow and infiltration (I/I).
- Rehabilitating the sanitary sewers is critical for maintaining sewer capacity and flows, while protecting the lakes due to their proximity to the sanitary sewer.
- Additionally, these areas are difficult for maintenance crews to access, so improving the condition of the sanitary sewer will aid in alleviating maintenance concerns.
What is CIPP?
Cured-in-Place-Pipe lining is a trenchless technology that will be ideal for rehabilitating these sanitary sewers because of its small equipment footprint and minimal land disturbance.
