Did you know keeping your lawn the right length can save water? Grass kept at 3 inches tall encourages deeper roots, is healthier during the dry times and can save up to 16-50 gallons of water per day. pic.twitter.com/390pt5FPp5 — Save Our Water (@saveourwater) October 23, 2019 Useful information.

Recently I found a Linkedin video where groundwater was extracted by a seesaw in a school.Its a nice idea as both energy and water is scarce and if we can use the momentum generated due to the movement of a seesaw to replace pumps for extraction of groundwater, then a sufficient amount of electricity can be conserved.  The harmonic motion of the seesaw can be converted into a linear motion of a tube-well to collect ground water.It is totally a zero energy concept which can be implemented where required.As seesaw is inexpensive the entire system will be cost effective.
