Technical basis
Vermont approves the use of harvested rainwater for reuse applications related to onsite non-potable water reuse, including in toilets and urinals, as HVAC make-up water, topping off swimming pools and washing cars, but does not set minimum water quality requirements (Vermont ANR, 2017). Rainwater harvesting is limited to rooftop runoff (Vermont ANR, 2017). All applicable provisions of the Clean Water Act (CWA) (33 U.S.C. §§ 1251 et seq.), including its implementing regulations, must be met in addition to any state water quality standards.
Onsite non-potable water reuse applications approved for use in Vermont
Vermont defines the following specific onsite non-potable water reuse applications for treated rainwater from rainwater collection and distribution systems:
- Toilets and urinals
- HVAC make-up water
- Topping off swimming pools
- Washing cars
- Landscape irrigation
Water reuse treatment category/type
Vermont does not assign harvested rainwater used for onsite non-potable water reuse to a category or class.
Vermont requires the use of a filter installed at the gutter or at the storage tank inlet to exclude debris such as leaf litter or sediment from entering the storage tank (Vermont ANR, 2017). Mosquito screening, 1 millimeter mesh size, must also be installed at openings to prevent mosquitos from entering the storage tank (Vermont ANR, 2017). Dependent on the intended point of use for the harvested rainwater, additional filtration may be required (Vermont ANR, 2017).
Additional context and definitions
Vermont requires specific design elements when implementing rainwater harvesting practices to capture and reuse rainwater runoff. In Vermont, rainwater should not be harvested from roofs manufactured using tar and gravel, asbestos, treated cedar shakes or lead-containing metal flashing (Vermont ANR, 2017). The use of asphalt shingle and painted metal roofs for rainwater harvesting is preferred (Vermont ANR, 2017). Storage tanks must be watertight, composed of and sealed with water safe, non-toxic substances and designed to capture at least 0.2 inches of rainfall from the contributing rooftop (Vermont ANR, 2017). If stored underground, the bottom of the rainwater storage tank must be above groundwater level and the top of the tank below the frost line. Storage tanks that are above ground or not able to be buried below the frost line must be appropriately insulated or disconnected during the winter months to protect the system from freezing (Vermont ANR, 2017). Vermont also provides specific required elements related to rainwater harvesting conveyance. These elements address overflow runoff and prevent ponding or soil saturation (Vermont ANR, 2017).
