The greatest problem of water conservation is to reduce the amount of runoff water. This is because: 

Clean water flows on the surface of earth due to excess of rainfall and melting of snow. 

When it begins to move the soil gets saturated in its complete capacity as a result of which the contaminants present at the top layer such as pesticidesfertilizers and petroleum flows along making it non-point source pollution.
