rainwater harvesting in Xochimilco

This project was done in the larger context of an MIT workshop led by Prof. Sheila Kennedy from the SA+P. It is part of larger effort collaborating with local non-profits and communities in Xochimilco to address water and food security.

My role was as a water resources engineer and designer providing water footprint estimates of different essential recorded community activities, and based of local climatic patterns. Building upon observations and discussion from site visits on current water use and rainwater systems, a community based network for rainwater harvesting was designed and provided for the community to have as a toolkit.

This is the resulting proposed network.

The proposed network makes use of greywater reuse for activities that do not require potable water, to prioritize and protect potable water sources in the already water scarce zone.

Additional relationships are provided between volume of tank and area of rainwater catchment surface, and estimated water footprint per different essential operations for the community to adapt the given network to their own.

More details on the project are found below.
