Bill Summary · SB 851

Legislative bill overview

SB 851 permits Virginia localities to establish ordinances regulating rainwater harvesting systems on private property. The bill became effective July 1, 2025, and grants municipalities authority to set standards for the installation, maintenance, and use of these systems within their jurisdictions.

Why is this important

Rainwater harvesting can reduce strain on municipal water supplies and lower residential water costs, but unregulated systems can create public health, drainage, and infrastructure concerns. This legislation provides a legal framework for localities to balance water conservation benefits with community safety and infrastructure protection through locally-tailored rules.

Potential points of contention

  • Property rights vs. regulatory authority: Some property owners may view local rainwater harvesting restrictions as excessive government control over personal water management, while others support local oversight to prevent contamination or flooding issues
  • Regulatory inconsistency: Different municipalities may adopt conflicting standards, creating confusion for residents living near jurisdiction boundaries or installing systems across multiple areas
  • Environmental trade-offs: While harvesting conserves municipal water, some worry poorly designed local ordinances could restrict the practice too heavily, limiting potential environmental and economic benefits residents could achieve
