Rain Centre Monitors Chennai's Water Table

The shallow aquifer can store rainwater and reduce water scarcity.

For 3 years, the Rain Centre has been monitoring the depth of the water table in Chennai. After dividing the city into 1 sq km blocks, an open well was identified in each block and whose water level was measured monthly.

To showcase this data and to continue for a couple of more years, RC turned to PWX. The PWX team ported all the existing data online and have trained the staff on using the PWX mobile app to enter new data.

RC's Founder-Director, Sekhar Raghavan, is very happy: "We were a little lost. Having collected data, we did not have a good way to see it graphed and mapped. PWX enables us to visualize the current data, which is very gratifying in itself. The correlation between water depth and TDS is visually obvious. PWX also makes it easy to enter new data and add photos. And most importantly, we are now in a position to share our work with decision-makers easily. We hope to increase Chennai's water security thru managing rainwater and the shallow aquifer."
