Town of Plainfield Water Pollution Control Authority

Attention Plainfield and Sterling residents! Please do NOT flush baby wipes and other flushable wipes down the toilet. Also, Closed restaurants must unplug (de-energize) your electric grease traps!

The Town of Plainfield has two wastewater treatment plants that are capable of treating up to 1.8 million gallons of wastewater a day. The wastewater is treated using physical, chemical, and biological processes.

The Plainfield North and Plainfield Village plants have been in operation since 1972 and consist of 13 pump stations and 100 miles of gravity pipes and 5 miles of force mains.    


Grinder Pump Alarm Procedures

    If the alarm on your grinder pump sounds, wait 15 minutes to see if it goes off on its own. The grinder pumps usually pumps between 12-6 gal/min and it is possible to overload the pumps when using large quantities of water.

 If the alarm does not go off, silence the alarm and restrict water usage. Call the Town of Plainfield Water Pollution Control at 860-564-3335. Hours of operation are from 6:00 a.m. - 2:30 p.m. if no one answers, leave a detailed message with your name, address, and phone number. You can also leave a message with the secretary at the Town Hall

at (860) 230-3015.  We will come and inspect the pump.


Power Outage

During a power outage or loss of power event the grinder pump will not pump and the alarm will not sound. Reduce water usage until power is restored. It is normal for the alarm to sound once power is restored as there is most likely a backup of water. The alarm should turn off within half an hour. If not, call (860) 564-3335

Household Sewer Back Up Procedure

Sewage blockages happen when debris build up causes the wastewater to be blocked off and not allowed to flow through the gravity fed pipes. They are often caused by rags, wipes, grease, and plant root build up.

 Blockages are often found when a homeowner realizes that  multiple drain ports like toilets and sinks are not draining, or when water is seen coming up from under a manhole cover.

Call the Plainfield Water Pollution Control if you think there is a sewage blockage. They will determine if the blockage is in the town owned sewer lines and if so will take care of any problems. If the backup is found not to be not in the sewer main line but in a house lateral leading up to the main, then it is up to the homeowner to call a licensed pumper to take care of the problem.

What NOT to put into a sanitary sewer!

Grease- Do not pour grease down the drain! Please pour grease into a container, let it solidify and throw it in the garbage
Tampon applicators
"Flushable" toilet brushes, wipes, and pads
Paper towels
Sanitary napkins
