“Planning for GIS Assets Mapping Testing of Water Quality and All Other Allied Works of All Public Drinking Water Sources In The State of

Maharashtra”

Water Quality Mapping

Introduction

• Water level is decreasing because of over exploitation, drying and resulted in to contamination of ground water

• Results of water contamination are also due to over population, increased fertilizer based agriculture practices and disposal of industrial waste

• Drinking water quality getting deteriorated day by day resulting in to health hazards

• Need to understand the drinking water quality with location based scientific approach and hence project is planned

• One time mapping and Geo-enabled database can be generated through this activity and future monitoring can be done

• Creation of awareness amongst rural parts of Maharashtra and hence project is very significant

Objectives

• To determine the quality of water in its natural state in Maharashtra

• To assess the impact of the activities of human beings upon the quality of water

• Observation of the sources and pathway of specified hazardous or harmful

substances

• To identity the contaminated source i.e. ground water based sources of

water, other water bodies of the planning

• To obtain reliable and 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.

• To create a Geo-spatial database of Pipe Water Supply Schemes by mapping

of all drinking water sources including all components of the scheme

Scope of Work

Item1 GIS survey, Marking of source, Digital Photograph, Creation of Integrated Geo-database

Item2

Survey of Piped Water Supply Scheme (PWSS) along with preparation of key plan, line Mapping, Creation of Integrated Geo-database

Item3

Collection of pre and post monsoon water samples in two years with mobile application developed by MRSAC and transportation to Lab per the standard procedure

Item4

Training to GSDA/ PHD lab officials, DWSM, BRC Sub Division Water Quality Consultants Jalsurkshak and Water Sampling Assistants in two years.

GIS Mapping (Spot Sources & small PWSS Scheme)

• Surveyor will carry Mobile loaded with WSSD application, list of sources and key map of villages, paint marker • Sarpanch / Jalsurakshak will guide surveyor the exact locations of the PWSS scheme and spot sources in the village

GIS Mapping (Spot Sources & small PWSS Scheme)

• For single source PWSS scheme, capturing should be done through PWSS module first • Rest of the spots are captured with the spot module application • Unique code generated in the application was written on the source and photograph of the same was captured • Sources are captured as per the given addresses in the list and the actual scheme is tagged to that address • In case of any new source which is not in the list, capturing is done under “New” option in the application with address

GIS Survey & Mapping Integration

• Data should be Sent to MRSAC and processed data should be done • PWSS line integration should be aligned along with the roads and should be snapped with the connected features like Valves/WTP/ESR/GSR/MBR etc.

Reports and Viewing (MRSAC portal)

• Various reports can be viewed on portal • Village wise data can also be checked on the portal

Lab Analysis reports

• Lab analysis reports are also available on the portal
