Groton Sewer Districts Expansion Policy

The Groton Sewer Commission is responsible for the management of two sewer districts - Groton Center Sewer District and Four Corners Sewer District. Demands for sewer allocation are approaching the physical capacities and cost limits of the systems.

The Groton Sewer Districts Expansion Policy has been adopted, effective April 19, 2023.

Groton Sewer Districts Expansion Policy (April 19, 2023)

The purpose of the policy is to accommodate sewer connection requests to satisfy public health requirements and to
promote economic development as possible within each district. However, with limited “upside” system capacity, the Sewer Commission has taken the position not to expand the sewer districts.

Effective April 19, 2023, the Groton Sewer Commission is instituting the following policies:

• Aggressively monitor and eliminate “inflow and infiltration” in the sewer system so as to reclaim available capacity.
• Service the needs of the in-district facilities as best possible.
• Consider sewer district expansion to properties only to service a failed septic system with no economically feasible replacement option.

Sewage System Discharge or Overflow Notices

When a sewer discharge or overflow occurs, the Sewer Commission sends out a public advisory notification. On business days, this webpage will be updated within 2-4 hours of the notification. During weekends or holidays, this webpage will be updated on the next business day.

You can also see a list of discharge and overflow events on the MassDEP website. This list is updated within 24 hours of when the public advisory notification is sent. Enter "Groton" in the Permittee field and click "Search".

The fastest way to get information is to sign up to receive public advisory notifications at the following link: https://www.grotonma.gov/government/notifications-and-alerts

To sign up to receive notices of sanitary sewer overflows, access "Public Meeting Agenda Posting and Minutes". Check the box next to Groton Sewer Commission.

History

The first three-member Sewer Commission was elected at the 1993 annual election, succeeding the former Wastewater Committee, which was an appointed body formed to plan and coordinate the design and construction of the present-day sewer system. The first connection to the sewer system was made in 1989.

Created by Town Meeting in 1985, and now known as the Groton Center Sewer district, it is comprised of Groton Center and the subdivision known as Partridgeberry Woods, added in 1989. In 1996, the Town Meeting voted to authorize an additional line to service approximately a dozen homes on Hollis Street, and in 2001, the Groton-Dunstable Regional High School. The Boston Road / Old Ayer Road extension was added in 2005. In 2007, an amendment to the existing Joint Use Agreement with Pepperell was approved to allow a 10-unit cluster “cluster” development on Olivia Way to connect to the Pepperell sewer line. These homes are considered part of the Pepperell Sewer System. At various times, the district has been extended by town meeting vote as reflected on the district map https://www.axisgis.com/GrotonMA/ (To see the Sewer Distract Maps you will need to select the layers on the GIS system).

Under an intermunicipal agreement with the Town of Pepperell, adopted in 1987, the Town of Groton purchased capacity of 120,000 gallons per day at the Pepperell Wastewater Treatment Plant for disposal of sewage produced in the Groton Center Sewer District.  In 2001, the Agreement was amended to authorize the purchase of an additional 56,250 gallons per day, and again in 2004 to authorize the purchase of yet an additional 97,500 gallons per day of capacity, bringing the total Groton capacity to 273,750 gallons per day. This represents 25% of the Pepperell plant’s total capacity of 1.1 million gallons per day. The Groton Sewer Commission manages Groton contracts with the Town of Pepperell to provide operation and maintenance for the system, including (in 1997) two pump stations; force main; manholes, laterals, and interceptors.

In 2019, the Groton Sewer Commission assumed responsibility to oversee the Four Corners Sewer District. The Four Corners District https://www.axisgis.com/GrotonMA/    operates under an intermunicipal agreement with the Town of Ayer, MA for the disposal of sewage produced in the Four Corners Sewer District.

The Commission is served by a part-time hourly office assistant.
