Septic System Regulations in Charlemont, MA

Charlemont is a small rural town in the hilltowns of Franklin County, situated along the Deerfield River corridor. There is no municipal sewer system in Charlemont, and all properties rely on private onsite septic systems subject to Massachusetts Title 5 (310 CMR 15.000).

Health Services

Charlemont’s Board of Health services are administered through the Franklin Regional Council of Governments (FRCOG) Cooperative Public Health Service (CPHS). This regional partnership provides Charlemont with professional public health staffing without the need for a standalone health department. The CPHS team handles permitting, system review, and compliance on behalf of the local Board of Health.

What Rules Apply

As of our last verification, Charlemont does not have locally adopted septic regulations beyond Massachusetts Title 5. Property owners must comply with the standard Title 5 requirements for:

• System siting and setbacks
• Design standards for soil type and percolation rates
• Inspection requirements at the time of property transfer
• Repair timelines for systems that fail inspection

Hilltown Considerations

Charlemont’s terrain — characterized by hillside topography and rocky soils — can make septic system design more complex and expensive than in flatter areas. Homeowners should anticipate the possibility of needing engineered systems or alternative technologies if conventional gravity systems are not feasible on their lot. A site evaluation by a licensed professional is the essential first step.

Permitting Process

All permit applications in Charlemont go through the CPHS regional system:

1. Contact FRCOG/CPHS in Greenfield to initiate your application
2. Have a licensed site evaluator assess your property
3. Work with a licensed engineer to prepare a system design
4. Submit plans for CPHS review and Board of Health approval
