You can help us to maintain the Hopkinton Sewer system and keep it working properly. A sewer system maintains a delicate biological balance to help ensure proper levels of gases, oxygen, pH and metals, along with the output of elements such as, phosphorus, nitrogen and nitrates.

The sewer system should not be used as a disposal system for trash, paints, oils, grease, gasoline or other hazardous and flammable chemicals. Even water base latex paint can disrupt sewer alarms and clog measuring equipment.

Not only can these materials cause damage to the pumps and piping but they pose an immediate risk to sewer personnel through chemical interaction and the formation of explosive gases. These materials will also pose major problems for the treatment plant.

In addition it is illegal to pipe gutters, drains or sump pumps into the sewer system this can cause excessive flow during heavy rains and could cause backups in your home. If you need help relocating your sump discharge from the sewer system, please give us a call and we will come out and help you find an alternative.

For those people that have a grinder pump installed, please read the information that came with the pump. A garbage disposal should not be used if you have a grinder pump and no foreign material should be flushed. Glass, metals, seafood shells, eggshells, and any other abrasives should be avoided as they can cause damage to the pump. Please ensure that your pump alarms are on and functioning properly.

In the case of a power outage water should be used sparingly, as the pumps generally store only about 50 gallons and your high level alarm will be disabled. If you do have a problem with your grinder pump please call either Todd Vogel at 508-435-9120, cell 508-735-8057, FR Mahoney 781-982-9300 or Weston and Sampson 978-532-1900 for emergency repairs. (FR Mahony is the local distributor for the E-1 grinder pump).
