Full Breakdown

Va. Code Section 32.1-248.2 directs the Board of Health to adopt regulations on the use of rainwater and reuse of graywater, describing appropriate uses and standards for harvesting systems. Outdoor rain-barrel capture for non-potable uses such as irrigation is generally unrestricted statewide. Any plumbing connection, or indoor potable use, is governed by the Uniform Statewide Building Code (Section 36-97 et seq.), which preempts conflicting local rules. Virginia offers no current statewide rainwater-harvesting income tax credit.

Violations & Penalties

No state penalties for residential outdoor rainwater capture. Plumbing-code violations follow the USBC fine schedule, typically $100-$500.
