GIS assets mapping and testing of water quality for all rural drinking water sources in Maharashtra
- To create a Geo-spatial database of Pipe Water Supply Schemes by mapping all drinking water sources including all components of the scheme.
- To determine the quality of water in its natural form in the state of Maharashtra.
- To assess the impact of the various activities performed by human beings upon the quality of water.
- To deeply observe the water sources and to check for presence of specified hazardous or harmful substances in water.
- To identify the contaminated source i.e. ground water based sources andother water bodies.
- To obtain reliab leand useful data of water quality as a whole and to adopt corrective measures to ensure safe supply of drinking water in rural areas.
- To train the villagers for future drinking water quality monitoring.
Methodology and Technology used
- Input of villages wise schemes were received from WSSO(Water Supply and Sanitation Organization) which was taken loaded in the application for survey
- Collection of GIS data with the help of Android application developed by MRSAC
- A-GPS and Glonass technology based handsets were used for high accuracy.
- GIS capturing was done for point data for individual sources (like hand pump/Well/bore well) by visiting all villages of Maharashtra. Pipe water supply and the pipe lines were captured for regional schemes as well as individual schemes (ESR/Raw water rising mains/pure water rising mains etc.).
- Photographs were also taken for the same.
- Data was uploaded to server and processed for finalization.
- Joint checking of data on ARCGIS was done between MRSAC/ZP/ADCC teams.
- The same GIS data will be used for Sampling of water with a concept of Geo-fencing to avoid field errors.
- Samples were collected in 180ml sterilized glass bottle for bacteriological and 1 ltr. plastic jerry can for Chemical analysis.
- Sampling bottles collected from field are submitted to GSDA Labs within 24hrs for analysis.
- The analysed data is later submitted to MRSAC of GSDA for linking and for further analysis of contaminated sources or areas.
- Training to all ZP officials as well as all Jalsurakhsakhs was given with help of running videos and hand outs.
- Entire data will be online that can be viewed by authorized users.
- Unique marking method helped in generating counts and status of all the sources online.
- Instant analysis wasbe done to generate reports of available contaminated sources
- Decision should be taken very fast in case of water scarcity and alternate sources should be provided for contaminated sources.
- Sampling was done properly due to geo-fencing application. Person has to go near the source to generate new ID for sampling every time.
- Training was given to the villagers for drinking water quality monitoring to be done in future, so that it improves their moral to serve the betterment of society.
- Same application was used by the department to update the GIS data as and when required.
- Project covers around 4.8 Lakhs spot sources and 66000 pipe water sources. Around 3.2 Lakhs sources will be samples within 2 years of span for both post monsoon and pre monsoon period
- It covers all 34 districts and 351 Talukas and 29000 villages across Maharashtra.
