Data related to the water sector although available online was very scattered and inaccessible and did not reveal much on its own when India Water Portal (IWP), Arghyam started the data project with the aim of providing better ways of accessing and representing data related to the water sector. The process led to some interesting learnings, revelations and very positive outcomes.

Cleaning, analysis and contextualizing the available data

The construction of a visual map of water supply to Bangalore city from available data sets on water quality and water related infrastructure by NEERI as a part of the data project started by India Water Portal, Arghyam was a challenging task.

The visualisation process

The construction of a visual map of water supply to Mumbai city from available data sets on water quality and water related infrastructure by NEERI as a part of the data project started by India Water Portal, Arghyam was a challenging task.

The visualisation process

Objective

To  visualize the water quality of Chennai over its existing water supply infrastructure map.

Roadblocks

Daily rainfall information at a weather station level is very useful data. It can be used for analysis and planning. A district average can't help people plan or monitor a situation in a real time manner. It is possible to aggregate up for trends but deaggrating is impossible especially for places like Uttarakhand where the climate can change drastically from one area to the other.  

Rainfall maps for the period of 100 years were created to see the changing patterns and differences over time.

Data used

MET data was used to generate the maps for every year.

The Indian Meteorlogical Department (IMD) defines drought as ‘the consequence of a natural reduction in the amount of precipitation over an extended period of time, usually a season or more in length, often associated with other climatic factors (viz.

Groundwater is water that is stored underground in aquifers or rock layers than can absorb water. India gets 85% of all its drinking water from this source.   

Rainfall is an essential part of monitoring groundwater as it recharges the aquifer and brings groundwater levels up. Rainfall and well levels are important parameters for data collection.

Groundwater is water that is stored below the ground in aquifers, or rock layers that can absorb water. India gets 85% of all its drinking water from this source.
