Please Note:

Effective June 1, 2020, the WPCF has changed their collection hours for Septic Vendors.
The collection hours will be 6:30 AM to 2 PM. You may come in during those hours to dump your loads.

  • Septic Vendors, please note, no loads will be accepted after 2 PM Monday through Friday.
  • Weekends, (Saturday & Sunday), no collections unless the request has prior authorization.
  • Thank you for your co-operation in adjusting your hours to accommodate our new hours.
  • ALSO, as a reminder, NO TRUCK WASHING, this causes WATER to be splashed ON THE WALLS OF THE TRUCK BUILDING, and THE FIRE PANEL GETS WET!!!

You will be prohibited from using the WWT Plant if bills are not paid on time, or if you are not accurate in the total gallons reported


The Town of Branford owns and operates a Water Pollution Control Facility located on Block Island Road, Branford, CT. The facility collects sewage from approximately I 00 miles of sewers and 50 pump stations in Branford as well as sewage from a portion of North Branford. The Town of Branford Sewer Authority oversees the construction and extension of the sewerage system and has the authority to enact user charges and assessment fees to owners benefiting from the system. The Water Pollution Control Department provides the daily operations and maintenance to the system. The system serves approximately 90% of existing commercial and industrial areas of Town and almost 85% of the residences.

The system was originally constructed in 1961 and provided secondary treatment for 1.5 MGD offlow. In 1982 the system was expanded and upgraded to treat 4.5 MGD of flow utilizing an oxygen generator to provide secondary treatment and anaerobic digestion for solids reduction. Treated effluent from the plant flows into Branford Harbor and ultimately Long Island Sound. On January 13, 2000, a thirty-month construction project began on the new treatment facility. The projected cost totaled $26,000,000, funded through a combination of State of Connecticut Clean Water Fund grants and 2% loans. With its completion, the facility now has the capacity to treat 4.9 MGD of flow and provide biological nitrogen removal with an effluent limit of 4mg/i of total nitrogen.

The sewers and pumping stations collect an average of three and one half million gallons per day (MGD) of wastewater and then direct the flow toward the facility for treatment and eventual discharge to Branford Harbor which is contiguous with Long Island Sound. During the past year, the plant treated over one billion gallons of wastewater. The Branford plant is permitted under a federal NPDES permit for the discharge of treated water and must comply with contaminant thresholds and removal efficiencies. As a rule, the NPDES compliance standards have become more stringent with every 5-year permit reissue. The Branford WPCF has consistently met those lower thresholds for pollution parameters required under the recent (August 2013) permit re-issue.
