Western Wayne County Regional Wastewater Treatment Plant Project
UPDATE:
June 2026
The new wastewater treatment system has been started up and operates in consistent compliance with the NYS DEC discharge permit. The Village of Palmyra, Town of Palmyra, Town of Macedon, Town of Walworth, and Town of Marion sewer flows are all being successfully conveyed to the new treatment system. The pump stations at each location are working well and the treatment system is stabilized and provides exceptional treatment.
re: Odor Control:
- All former anaerobic digestion tanks have now been removed and demolished as of mid-September and therefore has permanently alleviated an on-site source of odors from these construction activities at the Palmyra and Macedon sites. At this time, we believe these decommissioning efforts effecting the odors at the plant are generally complete.
- The WCWSA is also working on implementing some odor control/treatment at the new wastewater treatment facility influent building, where the majority of odors may naturally originate from the incoming sewage.
The Towns of Macedon, Marion, Palmyra, and Walworth have worked together with the Village of Palmyra and the Wayne County Water and Sewer Authority (WCWSA) to plan and design a modern, shared wastewater treatment system.
Each community originally explored upgrading its own aging wastewater treatment facilities. However, those individual improvements would have been costly and less efficient over time. By working together, the municipalities identified a regional solution that is more cost-effective, reliable, and better suited to meet future needs.
A Regional Approach
The project centers around a new 3.0 million gallons per day (MGD) Regional Wastewater Treatment Plant, located at the site of the previous facility in the Village of Palmyra. This plant will serve all four communities, replacing several older facilities.
Collaboration and Cost Savings
To make this regional project possible, the communities and WCWSA entered into an Intermunicipal Agreement (IMA). This agreement allows them to share costs, coordinate planning, and access grants and funding opportunities.
By working together, the communities will benefit from lower sewer rates for residents and businesses compared to upgrading and operating separate facilities. The new system is also designed to handle future growth, ensuring long-term reliability for the region.
