Congregational Church septic system may need to be larger

When the expansion of the Congregational Church on East Street was initially discussed six months ago, the board of health thought that the existing septic system would be adequate because it had been designed for the additional space. However, at the September 28 meeting, board chair Steve Opolski revealed, "We didn't realize they had not built the system as designed."

The church had submitted and received two permits back in 1967, one for a 1,900-gallon per day system which included provisions for the proposed sanctuary, and a second permit for a 1,200-gallon per day system which made no mention of the sanctuary. Town consulting engineer Rob Frado calculated the flow rate of the current system from "as built" information at 1,060 gallons per day.

Since high water tests were not conducted at the correct time in 1969, the board of health issued an order to install an interceptor trench to lower the water table. An interceptor trench is a deep trench with a buried perforated pipe which surrounds the leaching field to lower the table by siphoning off some of the water. Because there are no records indicating that the church built the trench, Frado suggested that a Title 5 inspection of the system would reveal whether the trench exists, as well as whether the current system is working properly.

Congregational Church members are expected to attend the October 12 board of health meeting with the Title 5 results.
