Odisha has a long coast line stretching over 480 km in length along the eastern boundary of
Bay of Bengal. These areas are highly sensitive in terms of saline water intrusion due to
excessive groundwater pumping to meet the water requirement of increasing population and
crop water demand. It is necessary that safe pumping options should be strictly followed to
maintain sustainable groundwater withdrawal. This papers deals with estimation of optimal
pumping options in two coastal districts of Odisha, i.e. Kendrapara and Jagatsinghpur, that
occupies 2nd and 4th highest position in terms of groundwater development status within the
State. Field studies were carried out to characterize the groundwater table depth fluctuation,
change in water quality, aquifer properties, and specific capacity of the study area. Pumping
test results in the study area showed that transmissivity value of aquifer ranged within 68.2 to
786.8 m2 day-1. Groundwater quality within the shallow aquifer was within the permissible limit
of irrigation use. Due to presence of good aquifer zones and source of groundwater recharge,
groundwater can be exploited safely in these areas. An analytical approach by using the Ghyben-
Herzberg model has been used to calculate the total fresh water flow towards sea, safe pumping
depth, well density, pumping mode within the study area. The model result indicated that even
though both districts are sensitive to salinity, depth of pumping should be restricted within 6-
9.5m and 16 to 24.5m in Erasama, Kendrapara areas respectively. Similarly well density could
be restricted upto 1-2 numbers per square kilometer along the coast line. Smaller horse power
pumps with 1-3 hp could be effectively used continuously for 4/5 hours in order to avoid saline
intrusion in these areas.
