Yes, rainwater collection is legal in Vermont, but subject to state and local water rights laws, with no statewide ban. The Vermont Agency of Natural Resources (ANR) permits non-potable use under the Water Supply Rule (2024), while potable systems require health department approval. Local municipalities may impose additional restrictions, particularly in drought-prone regions.
Key Regulations for Rainwater Collection in Vermont
- Water Rights Priority: Collection is permitted only if it does not interfere with existing riparian or prior appropriation rights, per 10 V.S.A. § 1021. Diversions exceeding 5,000 gallons annually trigger ANR reporting requirements.
- Potable vs. Non-Potable Use: Systems intended for drinking must comply with Vermont Drinking Water Rules (2023), including filtration and disinfection standards. Non-potable uses (e.g., irrigation) face fewer constraints but must avoid cross-connections with municipal supplies.
- Local Permitting: Towns like Burlington and South Burlington enforce additional ordinances, such as storage tank size limits (typically ≤ 2,500 gallons) and setback requirements from property lines. Check with the Vermont League of Cities and Towns for municipal-specific rules.
Post-2026, ANR plans to revise Stormwater Management Manual guidelines, potentially tightening collection standards for commercial properties. Always verify compliance with the Vermont Water Quality Standards before installation.
