Dear student,
1. Joy pumps : Attached below a merry-go-round wheel or a see-saw, is an arrangement similar to a conventional hand pump. As children ride on these wheels, groundwater is drawn and tank (around 8-10 meters above ground) is filled. It can also be used to pump water from bore wells and large storage tankers.
2.Go for a car wash : you can take your automobile to your local car wash. This way, you wouldn’t have to use the hose and in turn conserve more water.
3.Collect clean water for cleaning : when we wash our vegetables, fruits and meat make sure the tap water is not running. Collect this water for moping the house.
