Wastewater Treatment Plant (WWTP) Major Capital Improvements Project
In June, Delta Township hosted two public meetings offering the opportunity for the public to provide input and ask questions regarding the proposed reconstruction of the Wastewater Treatment Plant (WWTP).
The project is estimated to begin construction in the spring of 2022.
Why is this major capital improvement project necessary?
- The plant is at the end of its useful life.
- The plant needs new equipment to meet future water quality standards required by the State of Michigan
- The plant is nearing capacity.
What are the proposed improvements?
After identifying the large cost, construction difficulty, and inefficient operation of the plant associated with repairing and
retrofitting the plant, Delta Township’s project team developed a plan to reconstruct the plant on the same site. Reconstruction was found to be more cost effective to both build and operate and is anticipated to use 34% less energy than repairing and retrofitting the plant.
How Much will this Cost?
The total cost of all necessary improvements is estimated at approximately $78 million and the project will be constructed in multiple phases. The Township is planning to submit an application for low interest loans (est. 2 - 2.5%) from the Clean Water State Revolving Fund (SRF) to finance construction of the WWTP improvements late in July.
The Township is pursuing principal forgiveness funds that are available through the SRF for energy efficient “green” infrastructure.
The Township’s initial estimate is that sewer rates will need to increase by an average of 6% per year over six years. At the end of that six-year period the estimated residential monthly bill will have increased by approximately $10 a month. There are many variables associated with this estimate and actual rates may vary from this estimate. Even at this level, however, Delta Township’s sewer rates would remain competitive within the region.
Because the project will be constructed within the current fenced in boundary of the WWTP, it is not expected to have any significant negative environmental or social impacts. For questions regarding this project, you may contact WWTPproject@deltami.gov.
