RGNDWM Project - Ground water quality mapping – Methodology followed
Ground water quality is considered as a dependent
of type of geological material (XY, Z)and quality & quantity
of recharge water
Location of ground water sample is considered as a
point source for migration of contaminants
HGM unit (Spatial entity with XY, Z information) –t 1 & t2 is considered as a unit for (Interpolation & surface creation ) mapping ground
water quality
Inverse Distance Weighted (IDW) method is used for
interpolation of water quality data
Change in (Q Parameter & Season-wise) quality has
been brought out through union of respective layers

GAJRA SUB-WATERSHED (BLOCK- PATAN, DISTRICT- DURG,
CHHATTISGARH)
CASE-1
1. A rainwater harvesting project was taken up by PHED, Chhattisgarh
in the Gajra sub-watershed, Patan Block, Durg dist. which is
perennially water deficient in the region.
2. 101 recharge structures ( Masonary stop dam-23, percolation tank-
12, Boulder check dam-25, Nala bund-13 and desilting of pond-28)
were constructed in this sub-watershed based on the knowledge
gained from RGNDWM ground water prospects maps.
3. It was observed that the water table has risen to a maximum of 20m
at places with average rise of 15m as observed in 7 observation
wells drilled in the watershed.
4. As a result the sustainability of the ground water resource has
increased in the watershed and pre-monsoon water table is stable
around 10m BGL where as the post monsoon water table is stable
around 5m BGL.

(DISTRICT- MEDAK, ANDHRA PRADESH)
CASE-3
USAGE OF HGM MAPS BY RURAL DEPARTMENT, GOVT. A.P
FOR IDENTIFICATION OF FEASIBLE SITES FOR CONSTRUCTION OF
WATER HARVESTING STRUCTURES
As per Ground Water Estimation committee (GEC) 2007 report :-
•132 basins Over Exploited, 89 Critical and 175 in Semi Critical stage
out of 1229 micro basins formed by State Groundwater Department.
• This indicates nearly 32% of the area is facing drought conditions.
•Utilising HGM Maps it is planned for implementation of schemes for
396 basins to bring them to safe level by 2013.
•During 2010-11, 115 Over Exploited basins have surveyed in 12
districts covering 1984 Gram Panchayats.
•A total of 47,469 water harvesting structures were identified.
Methodology Followed
HGM maps of NRSC, and basin maps of CGWB & GWD
Superimposing basin map on HGM map
Enlarging to 1:25000 or 1:20000 or 1:14000 or1:10000 or 1:8000 scale
to suite the cadastral map scale for better understanding to the
stakeholders/ farmers.
Superimposing the cadastral maps on to the enlarged HGM maps
for prospective ground water zones as per survey numbers
Providing HGM maps basin wise to the stake holders/ farmers.

Feedback
•Appreciated the using of HGM maps for bringing the
awareness among the stakeholders in proper management
of Groundwater.
•Saved time in preparation of project reports with accuracy.
•HGM Maps indicating the availability of recharge sites
which are well understood by the farmers.
•The legend given in the HGM maps is highly valuable.
