Providing stable freshwater is the most persistent of the various environmental challenges on India's national perspective. Multiple influence factors like population explosion, rapid expansion, industrial growth and agricultural development are placingimmense pressure on water resources. This has ultimately resulted in high impact on quality and quantity of water. Summer and rainy seasons witness the eruption of water-borne diseases, such as, cholera, gastroenteritis and diarrhoea due to poor quality of drinking water and sanitation. Considering the seriousness of the water quality issue, government authorities have started the initiative of mapping the water quality in rural regions and take counter-measures to provide relief to affected areas.

 

Scope/Objective

  • 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.

Benefits/Results/Impact

  • 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.
