After 2 years of its launching, the data project by the India Water Portal looks back at how government water data accessibility has changed since then

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.

What does the mapping of the water quality data onto the existing water supply map of Chennai tell us?

Objective

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

Roadblocks

  • Map of water supply system was found with relative ease, but was surprisingly illegible and filled with details of little relevance.
  • Maps do not carry a time stamp, so it is difficult to verify the information they present.

Need for reference map

What can we do with daily rainfall data especially when it is available in usable formats?

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.

How has the rainfall pattern changed in the last 100 years across India? These rainfall maps provide a visual answer.

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.

Analysing monthly rainfall data from 1901 to 2002 helps understand the incidence of drought across the country.

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. high temperatures, high winds and low relative humidity) that can aggravate the severity of the drought event.'

Using a motion chart, the behaviour of aquifers using rainfall and well-level data is explained.

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.

The groundwater data collected by the CGWB has been criticized for various reasons. We analyse this data to understand the discrepancies, if any.

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. It is so important that there is a government agency called The Central Ground Water Board (CGWB) under the Ministry of Water Resources (MOWR), that is responsible for monitoring this precious resource.
