Hydrogeology Exploration
Hydrogeology is the part of hydrology that deals
with the occurrence, movement and quality of water
beneath the Earth's surface. The complexities of processes governing occurrence
and movement of ground water make the problem of
ground water assessment somewhat difficult, as not
only vast volume of data is required to be collected
but also many disciplines of science have to be
involved in a co-ordinated manner. Approach
and methodologies utilized have undergone gradual
changes based on the refinement of our understanding
in the field of ground water. This in fact will be a
continuous process as ground water is a dynamic
resource and science is in continuous search for
better understanding.
Raigad Drillwells is actively associated with the
geophysical logging and surface surveys for
groundwater. Application of surface and borehole
geophysics on regular basis in the seventies, for
the scientific evaluation of the subsurface
hydro-geological conditions required pin-pointing of
drilling sites and proper designing and construction
of water well. Raigad Drillwells has made extensive
use of both surface geophysical techniques as well
as borehole geophysical logging techniques fully
integrating them with hydro-geological and
geomorphological investigations and worked as
an inter-disciplinary team in various aspects of
groundwater exploration, environmental studies,
support to crisis management and special
applications. Geophysical exploration for
groundwater has become an
integral part of the exploration programme.
Water Supply Projects
Rain Water Harvesting
Open Wells & Ring Wells
Well Enhancement Programmes
Lift – Irrigation Projects
Recharge Well
Recharge wells can be of two types
-
Injection
well, where water is “pumped in” for recharge
-
Recharge well, where water flows under gravity
Rain Water Harvesting
The rain water in urban area can be conserved
through Roof Top Rain Water Harvesting Techniques
for artificial recharge to ground water. This
technique requires connecting the outlet/drop pipe
from roof of the building to divert the rainwater to
either existing wells/ tube wells / bore well or
specially designed structure.
Advantages
1. Rainwater is bacteriologically pure, free from
organic matter and soft in nature
2. It will help in reducing the flood hazard
3. To improve the quality of existing ground
water through dilution
4. Rainwater may be harnessed at place of need
and may be utilised at time of need.
5. The structures required for harvesting the
rainwater are simple, economical and eco-friendly.
In addition we also undertake programmes for Water
Conservation, Open Wells, Bunds and Check
Dams, Rock Anchoring, Piling, Rock Blasting
