UN Habitat estimates that 25% of the world's population lives in informal settlements. Informal settlements are communities with inadequate access to basic infrastructure and services. Residents often face severe problems related to water availability and management due to limited access to formal water infrastructure.
The system uses modular and low-cost sensors to help informal households in Mexico manage their water resources more effectively. The system was designed to easily integrate into the community's regular use of water. Water quantity is measured through a sensor placed on lids of water tanks and wells. Quality is measured through a TDS (Total Dissolved Solids) probe that floats in tanks and is constantly in contact with the surface of the water. Finally, usage and activity are measured using tilt switches that are activated whenever a bucket is flipped.
