On February 24, 2020, Public Works staff presented the 2020 Sanitary Sewer Master Plan to the Rochester City Council (click here for a video of the presentation). The Master Plan prioritizes capital improvement projects for maintenance of aging or deteriorated infrastructure, as well as identifies where capacity constraints of the current system would limit future development. The Master Plan also determined the infrastructure necessary to expand the system into undeveloped areas.

The City of Rochester pays for the initial construction of trunk sanitary sewer infrastructure into new developments and for trunk line improvements. Developers pay the City for this infrastructure via the Sewer Trunk Rates. As part of the Draft Master Plan, cost estimates were prepared for increased capacity and new line expansions in each of Rochester’s sanitary sewer zones, also known as “sewersheds.” The Sewer Trunk Rates in the Master Plan were based on the total cost of projects that would be required to serve the projected growth in the ultimate area divided by the acres that are available to be developed. Some sewersheds, such as Hadley Valley and Kings Run, have lower cost estimates because trunk lines sized for development currently exist and only line extensions would be required as development occurs. Other sewersheds, such as the South Zumbro, have higher cost estimates because development in these areas would require construction of significantly more infrastructure with less developable acres available.
