ABSTRACT

 

Water is one of the essential commodities for survival of human beings. It is required for domestic purpose, irrigation, industrial and other uses, which are very relevant for survival and progress of society. That is why important civilizations of the world have grown and prospered around perennial rivers. With rapid growth of population and development of modern technologies in various fields, the requirement of water has substantially increased. The perception that water is available with us in abundance no longer holds true now. Water is becoming an increasingly scare resource in many countries, as competition among agriculture, urban and industrial users become more common (Water Resource and Environment Technical Note F1, 2003). World wide agriculture is the single largest user of water, accounting for about 69% of all use. About 25% of water withdrawals supply the industrial and energy sectors and just 8% are used for domestic and household use. Water availability is neither adequate nor equitable to all human beings and in all regions of the country as well as in the world. The problem is more acute in Africa and West Asia and in many other developing countries including India. In addition to the problems of limited availability of water, there is problem of water quality leading to various biological and chemical contaminations. The major reasons identified for the shortage are uneven distribution of rainfall, which is received in 100 hours a year as against 8,760 hours, inadequate harvest and use of available rainwater, and unscientific management of ground water. The ground water, which was abundantly available at shallow depth upto mid-seventies, depleted and had gone down to the level of beyond 100 meters at many places1-3.
Because of these problems the need of water conservation is being realized everywhere and consequently various schemes for augmentation of water supply and conservation of water bodies have been started by many governments through community participation.
In India, number of surface water resources has become polluted. In last few decades, the pollution level has led to such a grave situation that hardly any water resources are available which could be used without a hitch. Therefore there has been a growing concern for conservation and management of the available water resources4.
The Laharpur reservoir situated in the outskirts of the Bhopal Town (India) has become a victim of pollution due to anthropogenic activities. Since its construction the reservoir, is subjected to the process of siltation which has reduced its depth substantially besides the inflow of sewage in last decade has resulted in increasing the nutrient level. The accrual of nutrients in the reservoir resulted in prolific growth of weeds. Mortality of fishes has been reported at many instances.
The deterioration of water quality has invoked the need for conservation and management of the reservoir. The present paper is focused towards the problems and consequent conservations strategies to be adopted for abatement of pollution and conservation of the reservoir.
