About Rainwater Directory

Our Mission

Freshwater scarcity, aging municipal infrastructure, escalating utility rates, and severe droughts across the United States have made decentralized rainwater harvesting one of the most critical sustainable water practices of the 21st century.

Yet property owners navigating rainwater catchment face widespread misinformation: confusing Western water rights doctrines, outdated myths that collecting rain is "illegal," opaque contractor pricing, and complex plumbing and backflow prevention codes.

Rainwater Directory was created to bridge this gap. We are an independent, research-driven directory and consumer education resource dedicated to providing:

• Evidence-aware contractor directories: Free, searchable access to rainwater providers with visible source-review status.
• Statutory & Regulatory Clarity: Up-to-date, statute-by-statute legal guidance citing primary state codes, plumbing standards, and municipal rebate programs.
• Engineering & Health Best Practices: Technical guides developed in accordance with national industry standards, including ASPE/ARCSA/ANSI Standard 63, the Uniform Plumbing Code (UPC Chapter 16), and NSF/ANSI water treatment protocols.

Our Editorial Standards & E-E-A-T Commitment

Rainwater harvesting impacts structural safety, property foundations, and drinking water potability. Because bad advice can lead to property damage or waterborne illness, our content adheres to the highest standards of Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T):

1. Primary Source Verification

Our target standard is to verify regulatory claims, statutory limits, and tax incentives against primary legal and governmental sources. Pages still being migrated to claim-level evidence are labeled as source review in progress:

• State statutory codes (e.g., Texas Tax Code § 151.355, Colorado C.R.S. § 37-96.5-103, Utah Code Ann. § 73-3-1.5, California Water Code § 10570).
• State environmental protection agencies and natural resource departments (e.g., Texas Commission on Environmental Quality, Washington Department of Ecology, California Water Resources Control Board).
• Municipal utility water conservation and rebate program guidelines (e.g., Austin Water, Tucson Water, San Diego Water Authority).

2. Professional Industry Standards

Our technical guidance is aligned with recognized North American rainwater catchment and plumbing engineering bodies:

• ARCSA: American Rainwater Catchment Systems Association standards for Accredited Professionals (ARCSA AP) and system inspectors.
• ASPE / ANSI Standard 63-2020: Rainwater Catchment Systems (design, installation, and sanitation standards for potable and non-potable use).
• ASSE 5110: Standards for Backflow Prevention Assembly Testers to safeguard public water mains from cross-contamination.
• NSF / ANSI Standards 53, 55 (Class A), and 61: Drinking water filtration, ultraviolet microbiological disinfection, and health effects of system components.

3. Zero-Hallucination Policy

We operate under a strict zero-hallucination policy. We never fabricate contractor listings, customer reviews, ratings, licensing credentials, municipal rebate amounts, or statutory codes. If local regulations in a jurisdiction are ambiguous or pending legislative action, we state so clearly and direct readers to their local municipal building authority.

How We Vets & Review Contractors

Rainwater harvesting is a specialized trade combining roofing, earthwork excavation, plumbing, and electrical engineering. To maintain directory integrity, our contractor listings are subject to ongoing verification:

• Licensing Verification: Confirming active business entity registration and appropriate trade licensing (such as Master Plumber, C-36 Plumbing, or Registered General Contractor licenses where required by state law).
• Professional Credentials: Identifying installers who hold ARCSA AP certification or specific rainwater catchment credentials.
• Service Transparency: Clearly categorizing contractors by their reported capabilities and showing whether independent source verification is complete.
• No Pay-to-Rank: Organic directory listings cannot be purchased. We do not accept payment to inflate contractor ratings or prioritize unverified businesses over qualified professionals.
