Rain water colect system and soil protection

High-Level Project Summary

The Ailewu Ilê team had developed a project that intents to minimize environmental injustice with the challenge ‘Space for change’. The goal of this project it's to colect rain water using a drain system that captures it and filters it by biofiltration (with biologicly activated coal) and stores potable water for the collective use. We also intent to provide protection for the soil against landslides by covering the soil with a flexible concrete blanket. With the help of a cistern the water can be stored and distributed straight to the houses, making the clime change work in favor of the population and reassuring the safety and life quality of the marginalized people.

Detailed Project Description

The application of flexible concrete blankets is practical and quick, in addition to showing good durability and resistance. In the upper and lateral corners, there are rain water colect spots installed. These colect spots are containers connected to each other by piping. In its surface layer, a geotextile blanket will be used for drainage, which, in addition to being resistant and permeable, can act as substitutes in the water particle size filtration process.

Just below the blanket, the conteiner must  have a biologicly activated coal biofilter. The water collected by the system goes through a biofiltration process using biologicly activated coal  or slow filtration, which is the oldest water purification process. biologicly activated coal helps control the microbiological growth, which acts on the decomposition of recalcitrant organic substances and allows the reduction of  chlorinated disinfectants in water usage, utilized in microbiological control, but it could leads to a formation of toxic halogenated by-products, thus making water fit for consumption.

The collect water system and protection for the soil intents to minimize the landslide that very common at intense rain season. Its instalation must be studied and can be applied in slopes where the containment is not complex and the application of the flexible concrete blankets is possible. The system must be istalled taking advantage of the inclination of the slopes because the gravity makes the water filtering  and later storage easier.


Space Agency Data

The landslide risk areas identification is based on data available on the Global Precipitation Measurement (GPM) a system developed by NASA that provides in near real time precipitation estimates on a global scale. The GPM system uses the combination of data from different radars and multi - satellite to assess and estimate rainfall around the world, so it can be used as a crucial tool to monitor and predict disasters caused by excess or lack of rain, including landslides around of the world.

Hackathon Journey

Our team, which in addition to assisting in Salvador cases of landslides and the collapse of houses during rainy seasons, are sensitive to the social and climate injustice that affects low-income populations, discriminated racial groups, traditional ethnic peoples and to working-class neighborhoods. The use of space apps helped in specifying climate disasters caused by rain. The experience was enriching for the group.
