Is water conservation necessary ? Give reasons.
- Distribution of fresh water is highly uneven. Large tracts are deficient in rain as well as ground water,
- At most places more water is withdrawn from reservoir and underground source than their recharging
- Requirement in urban and industrial areas is nearly always higher than the availability,
- Further demand for water is rising by 4 – 8% annually in all fields, whether agriculture, industry or domestic use.
Therefore, water conservation is necessary. Wastage of the resource should be prevented. Waste water should be recycled. Water harvesting involving recharging of ground water should be practised.
