Answer 1

Pumping used water back into the soil is not a conventional method of water harvesting.

Explanation:  

• Water harvesting occurs when the rainwater is collected, stored and is used for several purposes of irrigation, agriculture, flushing of toilets, washing of cars and others.
• When used water is collected, it is sent for filtration so that it can be used again.
• This water is not merely collected and flushed into the ground, and this is against the principle of water harvesting itself.
