Is Rainwater Collection Legal in Puerto Rico After the 2026 Framework Overhaul?

Yes, rainwater collection is legal in Puerto Rico, subject to compliance with local water management and structural safety regulations.

Puerto Rico permits rainwater harvesting for non-potable uses under the Ley de Aguas de Puerto Rico (Law No. 136 of 2009) and Reglamento para el Manejo de Aguas Pluviales (2018), provided systems meet structural integrity and sanitary standards. The Autoridad de Acueductos y Alcantarillados (AAA) oversees enforcement, while municipalities may impose additional zoning or permitting requirements. Recent 2026 amendments to the Código de Construcción de Puerto Rico mandate secondary containment for systems exceeding 500 gallons to mitigate contamination risks.


Key Regulations for Rainwater Collection in Puerto Rico

  • Permitting Requirements: Systems over 1,000 gallons require approval from the AAA under Reglamento 8032 (2020), which includes structural load calculations and leak prevention protocols.
  • Non-Potable Use Only: Collected water must not be used for drinking, cooking, or bathing unless treated via AAA-certified filtration systems (per Norma 2017-01).
  • Zoning Restrictions: Municipal ordinances in San Juan, Ponce, and Caguas prohibit collection in flood-prone zones or historic districts without a Certificado de Uso de Suelo (Land Use Certificate).
