Norwood and Walpole Join Forces on Interceptor Sewer Project to Solve Traphole Brook Pollution and Unlock 150 Acres for Development-September 17, 1962

Through a cooperative municipal initiative, the towns of Norwood and Walpole are launching a joint interceptor sewer project designed to eliminate long-standing pollution in Traphole Brook caused by unsewered domestic refuse from hundreds of residential properties.

Resolving a Decade-Long Public Health and Development Crisis

According to Norwood Health Agent Bartley King, the planned sewer system will resolve roughly 90 percent of the pollution affecting Traphole Brook, a tributary of the Neponset River. For the past ten years, failing septic tanks and direct drainage lines from more than 100 homes in southeast Norwood and 300 homes in northeast Walpole have created a persistent public health hazard.

While Walpole did not restrict building, the severe land pollution prompted the Norwood Board of Health to withhold more than 100 intentional builder’s permits across the Summer Street, Union Street, and Route 1 corridor. This precautionary ban left over 150 acres of land idle, depriving the town of potential tax revenue. Once completed, the new infrastructure will clear the area for the development of approximately 300 residential and commercial lots.

Project Engineering and Cost-Sharing Breakdown

To remedy the issue, Norwood and Walpole agreed last year to construct an 8,000-foot interceptor sewer system utilizing reinforced concrete and asbestos-cement pipes ranging from 14 to 36 inches in diameter.

• Routing: The main line originates in Walpole west of Route 1, parallels Traphole Brook, crosses under Route 1 and Summer Street, swings north with the brook, and ties directly into the main Metropolitan District Commission (MDC) trunk line located behind the Norwood Arena. Sewage will be safely transported to the Nut Island Sewage Treatment Plant for ocean disposal.
• Financing: The total estimated construction cost is $211,800. Under the Federal Water Pollution Control Act, the federal government is funding 30 percent ($61,800). The remaining two-thirds is split between the two municipalities based on projected sewage flow: Norwood is covering 73.6 percent ($97,439), while Walpole is contributing 26.3 percent ($34,861).

Construction bids are scheduled to be opened on September 28, with project completion anticipated by June.
