One of the most powerful programs to face  climate change in areas affected by drought or lack of clean water

About the project

The Rain Harvesting Tank was developed by Fundación Plurales, under the program originally called Sed Cero

It enables communities to use locally sourced materials to build a rain harvesting tank to get access to clean water, both for private use and agriculture production.

The formula

Impact and Main Outcomes

One of the main effects of climate change is the change of weather patterns and, consequently, the variation in the amount of rain that a certain rural area receives.

This project enables families and communities to collect more efficiently rainwater, instead of being forced to use the water of polluted rivers or having to build wells. This system also enables communities to optimise the water for private use and agriculture, especially when matched with low-cost hydroponics systems.

This Blueprint is being updated!

We are currently migrating our 50+ blueprints to this new platform.
