GROUNDWATER EXTRACTION AND WASTE WATER DISPOSAL REGULATION –
IS LAHORE AQUIFER AT STAKE WITH AS USUAL APPROACH? (journal review)
ØIn this paper we have
focused Maintaining the water
balance of withdrawals and recharge is vital for managing human impact on
groundwater resources.
ØFurthermore, there is
no mechanism for allocating groundwater nor regulating its use.
ØAny landowner can
install a tube well and begin pumping groundwater to the extent of his
satisfaction.
ØVarious options for
Lahore aquifer management should be designed to achieve the following
objectives:-
1.Groundwater mining
balance can be reduced or even made zero by supply and demand side management.
2. Through appropriate adoption of regulation policy and
strategic actions such as building recharge structures in Ravi bed for
groundwater recharge during wet years, the current worrying situation can be
reversed to preserve and improve the groundwater quality and to ensure its
availability on equitable and sustainable basis.
§Each and every use of
existing groundwater above 0.20 cusecs should be registered with all the allied
information regarding his borehole and quantum of pumping.
§Each new user should
be required to get a permit before installation of pumping equipment .
§Monitoring of waste
disposal at key points should be done to act as guiding tool for finding point
sources of major pollution in the surface drains.
§ It is recommended
that all sewerage being disposed into the Ravi River should be conveyed in to a
lined channel built along side the edge of the river bed. This can help
reducing the pollution loads to the aquifer.
§ Every user of
groundwater should be charged with certain amount of groundwater development
and management surcharge.
§Why this Happens:
•The Lahore city does
not have any rainwater or surface water recharge mechanism or entitlement to
any river supplies.
•No regulation exists
with respect to installation of groundwater pumps and the volume extracted
there from by any individual, community or industry.
•Farmers living near
the drain frequently use its water for irrigation.
•Many of the
industries particularly the small one and municipal waste is being discharged
into the surface drains in and around the Lahore city.
