GROUNDWATER EXTRACTION AND WASTE WATER DISPOSAL REGULATION

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.

EcoVillage at Ithaca, New York

Overview: Initiated in 1991 Location:2.5 miles from downtown Ithaca, NewYork , USA. Total land: 175 acres. 50 acres land for conservation. Two food farms producing food for 1500 inhabitants. 60 homes clustered in 10 acre of land. INTRODUCTION The ultimate goal of EcoVillage at Ithaca is nothing less than to redesign the human habitat. We are creating a model community of some five hundred residents that will exemplify sustainable systems of living - systems that are not only practical in themselves, but replicable by others. The completed project will demonstrate the feasibility of a design that meets basic human needs such as shelter, food production, energy, social interaction, work and recreation while preserving natural ecosystems ( EcoVillage at Ithaca Mission Statement 1994). Demonstrating Best Practices at EcoVillage Ithaca: 1. Green Building, Energy Efficiency, and Renewable Energy: All homes are passive solar, super-insulated, and many have photo

EKISTICS (An Understanding as Urban Planner)

• The term Ekistics was coined by Greek architect and urban planner Konstantinos Apostolos Doxiadis in 1942. • Applies to the science of human settlements . • Includes regional, city, community planning and dwelling design. This science, termed Ekistics , will take into consideration • the principles man takes into account when building his settlements , as well • as the evolution of human settlements through history in terms of size and quality . • The target is to build the city of optimum size , that is, a city which respects human dimensions. • Since there is no point in resisting development, we should try to accommodate technological evolution and the needs of man with in the same settlement. • ACCORDING TO DOXIADIS In order to create the cities of the future, we need to systematically develop a science of human settlements. • Ekistics aims to encompass all scales of human habitation and seeks to learn from the archeological and historical record
