Water Audit
1) To measure system input.
2) To identify & measure system input & output points
3) Measurement of authorised / unauthorised
consumption
4) Measurement of water losses (Leaking Pipe, NR
connection, Damaged Water Meter etc.)
5) Loss reduction, leak detection & corrective
measures.
6) Analyse water audit results for NRW / UFW
7) To calculate the actual N.R.W. by using Flow Meter

Water Quality Mapping
“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”
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
GIS survey, Marking of source, Digital
Item1 Photograph, Creation of Integrated Geo-database
Survey of Piped Water Supply Scheme (PWSS)
along with preparation of key plan, line Mapping,
Item2 Creation of
Integrated Geo-database
Collection of pre and post monsoon water
Item3 samples in two years with mobile application
developed by MRSAC and transportation to Lab
per the standard procedure
Training to GSDA/ PHD lab officials, DWSM, BRC
Item4 Sub Division Water Quality Consultants
Jalsurkshak and Water Sampling Assistants in two

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

•
•
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)
