Wilbraham Septic Regulation Analysis

No Title 5 Addendum — State Baseline Applies

Last reviewed: March 8, 2026

📋

What This Means

Wilbraham has not adopted a Title 5 supplement. Septic system design follows the state baseline under 310 CMR 15.000 without local modification. The Select Board serves as the Board of Health and is part of the Eastern Hampden Shared Public Health Services (EHSPHS) group with Hampden, Longmeadow, and Monson. Local provisions are limited to septage hauler permitting and general maintenance guidance — no enhanced setbacks, no nitrogen sensitive area designations, no mandatory I/A technology, no local bedroom definition changes. Wilbraham is among the least constrained towns for ADU septic compliance.

Gap Comparison

Provision	Title 5	Local Rule	Gap
Title 5 Setback Distances	50 ft wetland/surface water; 100 ft private well; 25 ft irrigation well; 10 ft property line; 20 ft foundation	No Title 5 supplement adopted. State baseline applies without modification.	None
Septage Hauler Permitting	Septage hauler licensing at state level	Separate Septage Hauler Permit required beyond general Private Hauler Permit. Equipment inspection required. Records maintained for 1 year and submitted within 30 days of pumping.	None — administrative requirement, not a design constraint

Methodology

This analysis compares local Board of Health supplementary rules against the state Title 5 baseline (310 CMR 15.000). Unlike zoning — where Chapter 150 preempts certain local restrictions — local Boards of Health are explicitly authorized under M.G.L. c. 111, § 31 to adopt standards stricter than Title 5. Exceeding the state baseline is not a legal deficiency. This analysis measures the gap between local and state requirements and assesses practical impact on ADU feasibility. It does not constitute legal advice.
