Permits
Septic permits and rules in Winchester
Winchester's Board of Health lists 20 regulation topics, and none of them concerns septic systems or Title 5; the one closest to the ground is a 1989 regulation on wells (Board of Health regulations). The Board's fee schedule effective July 1, 2026 lists no septic, perc or septage hauler fees, only a $50 non-potable well permit and a $50 well driller permit (2026 fee schedule). In other words, there's no local septic program here.

State rules still apply. If a Winchester property does turn out to have a working system, state Title 5 governs it: a Title 5 inspection within two years before a sale, or three years with yearly pumping records (MassDEP buying or selling guide), by a MassDEP-approved System Inspector from the NEIWPCC list. Title 5 bars building a new system, or upgrading or expanding an existing one, where sewer connection is feasible, with listed exceptions (310 CMR 15.004). Digging for a sewer lateral or around an old tank needs a Dig Safe notice at least 72 hours ahead, weekends and holidays excluded (M.G.L. c.82 §40A).

Sewer or septic
Sewer or septic in Winchester
A sewer town. The 2025 Open Space and Recreation Plan says town sewer service is part of the MWRA system and that, as Winchester does not rely on septic systems, wastewater hasn't been a limit to development (OSRP 2025). MWRA's FY2027 final assessments list Winchester among its full sewer customers (MWRA FY27 assessments).
Connection rules. The DPW's Public Sewers and Storm Drains Rules and Regulations, adopted September 13, 2021 and effective October 25, 2021, give all owners of abutting properties equal rights to connect; we found no rule that requires it. A new connection needs 30 days' notice to the DPW Director, must flow by gravity unless an approved lift is needed, and each unit in a multi-family building needs its own building sewer. The owner pays all installation and connection costs; the rules set no connection fee but allow review fees (Sewer and Storm Drain Rules).
Leftover tanks. An old tank, cesspool or holding tank can still turn up on a long-sewered lot during an addition, a pool dig or a sale. With no local septic regulation, the Health Department is the place to ask how the town wants it handled before it's filled or removed.
Water
Water Winchester protects
The Fells reservoirs. Winchester draws part of its drinking water from the North, Middle and South Reservoirs in the Fells and the rest from MWRA. Their watersheds are a Zone A Water Supply Protection Area, with Zones B and C also regulated, and the plan says the North Reservoir may be used for no other purpose (OSRP 2025). The same plan says groundwater near Horn Pond recharges the City of Woburn's public wells, so what goes into the ground in that corner of town matters next door too.
A 25-foot buffer. Wetlands bylaw buffer regulations approved May 27, 2025 bar, with limited exceptions, grading, filling, excavating, paving or structures within 25 feet of wetlands, lakes, ponds, rivers and streams, and require projects in the 100-foot zone to improve that 25-foot buffer (wetland buffer regulations). A lateral or tank dig near the Aberjona River or a pond starts with the Conservation Commission.
Floods and soils. The town's flood hazard page says any property in Winchester is susceptible to basement flooding (Local Flood Hazards). The open space plan describes droughty, sandy, gravelly Hinckley soils, rocky, shallow Hollis soils and ledge at Mt. Pisgah.
Winchester's homes
Older single-family homes, long on the sewer
Winchester has 8,073 year-round housing units, 78% of them single-family, according to 2020 Census figures in the Housing Production Plan provisionally adopted December 16, 2024 (Housing Production Plan). The town's energy page notes that the building code didn't require insulation before 1965 and says most Winchester homes “were built so long ago” (Energy Efficiency).
An older house that has drained to the sewer for generations can still have an aging lateral under the lawn and, now and then, a forgotten tank. If either comes up during a sale or a renovation, the DPW handles the sewer side and the Health Department the old-tank side.
FAQ
Winchester septic and sewer questions
Does anyone in Winchester still have a septic system?
The town's 2025 Open Space and Recreation Plan says Winchester does not rely on septic systems, and the Board of Health posts no septic regulation or septic fee. The town doesn't publish a count of any that remain. Any system that does would fall under state Title 5 through the Board of Health.
Who pays for a new sewer connection in Winchester?
The owner. The town's Public Sewers and Storm Drains Rules and Regulations, effective October 25, 2021, put all installation and connection costs on the owner, require 30 days' notice to the DPW Director, and require the connection to flow by gravity where possible, with an approved lift otherwise.
What should I do about an old tank found on a sewered lot?
Call the Health Department before anyone fills, removes or digs around it. Because Winchester has no local septic regulation, the Board of Health works from state rules, and it can tell you what it wants done.
How close to a pond or stream can a contractor dig in Winchester?
Generally not within 25 feet. The wetlands buffer regulations approved May 27, 2025 bar grading, filling, excavating, paving or structures in a 25-foot buffer around wetlands, lakes, ponds, rivers and streams, and projects in the 100-foot zone must improve that buffer.
What does it cost me to use New England Septic Pros?
Nothing. Asking is free for homeowners; the contractor prices the job, and the price and contract are between you and them.
