Please don’t flush anything down the toilet other than human waste and toilet paper!  On January 18th 2022 we experienced a sewer main blockage that resulted in an overflow of approximately 20,000 gallons of untreated sewer into Beaver Brook.  The blockage was caused by grease and so-called “flushable” wipes.  These wipes do not break down like toilet paper and cause blockages and clogged pumps.  Also, commercial grease traps need to be cleaned often and the grease removed.  If you have any questions, please contact Chief Operator John Lazelle at 464-3862.  Thank you for your help.

This Facility was built in 1964 as a Primary Treatment Plant.  We had a major upgrade in 1987 making the plant a Secondary Treatment Facility.  In 1989 we expanded our collection system which now includes 7 Pumping Stations, 220 manholes, 275 connections and approx. 7 miles of sewer lines.  We are now just finishing up our current refurbishment project which involved upgrades to our primary treatment process, a new office/lab and primary treatment building, improvements to the control building and major electrical component upgrades including a new 80 KW generator.
