In May of 2019, the AguaVida Coalition submitted recommended changes to the municipal construction code, which would require rainwater harvesting on all new developments. The code was broken down into two main points:
- All new development projects in the municipality, commercial or residential, must present a detailed rainwater harvesting plan, which needs to be authorized by the corresponding department. Plans must include best practices for rainwater harvesting systems (active and passive), and include: capture, distrutibion, storage, infiltration, and treatment of rainwater;
- For every m2 of roof surface in new residential and commercial developments, there must be a minimum of 0.4m3 of "active" rainwater storage, which is to say rainwater that is stored in either above ground or below ground cisterns.
Below is a copy of the signed and received version of the AguaVida Coalition's recommendations to change the municipal construction code.
