Water Pollution Control Authority (WPCA)


The goals of the Town of Ledyard Water Pollution Control Authority are to: Efficiently collect, transport, and treat the incoming wastewater, producing pristine effluent while preserving the environment, protecting natural resources, and providing clean quality water for the downstream users.



Wastewater Treatment Plant

The Ledyard Highlands Wastewater Treatment Facility (WWTF) was upgraded in 1997. This upgrade included Sequencing Batch Reactors with:
  • Automatic backwash sand filtration
  • Fine air diffusers
  • Flow equalization
  • Ultraviolet light disinfection
This tertiary system provides a state of the art wastewater treatment facility for the community of Ledyard. This includes a septage receiving area and a rotary drum thickening component of the plant processes. These 2 most recent additions to the facility continue to save a significant amount of money in solids handling costs.

Sanitary Collection System

The sanitary collection system consists of approximately:
  • 2 miles of force mains
  • 2 pumping stations
  • 6 miles of gravity pipe
The plant capacity is 0.26 MGD. The plant can handle peak flows of 0.80millions of gallons per day (MGD). Currently the average flow into the facility is 0.17 MGD.

Class IV Facility

The Ledyard Highlands WWTF is rated as a class IV facility. This is the highest designation for plants in the State of Connecticut. It takes a dedicated and professional staff to operate and maintain such a facility. We are proud to continue to provide the residents of Ledyard with the quality of service that they deserve while protecting the environment and natural resources of Southeastern Connecticut.
