Groundwater table maps

These maps are interpolated groundwater depths, in metres below ground surface. Between December 2015 and now (September 2017) monthly measurements of depth to the static water table were made at approximately 150 locations across Bangalore. These measurements were largely made at abandoned/unused borewells.

Below, individual interpolated groundwater maps of the static water table can be viewed/downloaded. An animation is also provided. The locations of each well that was monitored are indicated by the circles.

Groundwater levels from 2007 to 2013

Measurements of groundwater levels in Bengaluru by students

This map layer compiles more than 1000 measurements of groundwater levels in different parts of the city since 2007. Under the guidance of Dr. Muddu Sekhar, Associate Professor in the Dept. of Civil Engineering, various Indian Institute of Science (IIsc) student research projects have been conducted over recent years within Bengaluru city limits.

This interactive map layer compiles the entire data collected between 2007 and 2013. Clicking on each point brings up corresponding information for that point. This includes groundwater levels for each point, in metres below ground level. The date on which the measurement was taken is also listed.
