2. To avert this impending crisis, conservation of every drop of water
must be done. Every nation must implement the following 6-point
strategy for developing a sustainable Water Security System:i) Rain water harvesting & storage ii) Participatory water-shed management, desilting & renovation of
ponds & reservoirs iii) River water sharing & its efficient use iv) Waste water management. Treatment & recycling of sewage water
& industrial effluents v) Sea water usage along the coast lines, mangrove plantation vi) Use of efficient irrigation techniques. 4. The MOTTO is to utilize the resources as per its capacity of
“replenishment”, so that perpetual supply can be ensured. 5. Inculcate habits in children (as future responsible citizens) through
schools to use water with utmost care and respect, similar to that
as given by poor people to ghee:C) Waste Water Management:Water treatment requires consideration of all consequences for the environment; other wise one problem would be transformed in another serious problem. Pollutants can be modified, either by recycling to make new products or by purifying, so that the end products are less harmful to the environment. Environmental damage can be reduced by replacing chemical materials and processes with biological technologies, like 1. Bio-catalytical method. 2. Bio degradations with micro-organisms. 3. Genetic modification to improve pollutant bearing tolerances, 4. Use of bio-sensor to monitor and render pollutants harmless. Various methods for decontamination of effluents or to render pollutants harmless are:1. Precipitation by raising the pH of the solution. It is the simplest
method.
