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.

Thank You!
