A Case Study on Water Storage Tank Design, Constrution, Operation and Assessment in District Kalat, Balochistan

Abstract

Balochistan has been blessed with all types of ecological zones; the only limited factor is water. Also grow more food by each drop of water is the cry of the day. For this it is utmost important to take maximum discharge from already design structures. In Balochistan there is no irrigation at night and tubewell is operating full night whose discharge were wasted and Electricity load shedding problems are also there especially at day time. For this a storage tank is required which stores water for further utilization at day time irrigation hours. For the design of storage tank the tube well discharge ,its operating hours and other parameters were assessed. Discharge of tube well was determined by using trajectory method which was 10 lps. Ten hours were taken as operating hours The construction of the water storage tank involves different steps that are removal of vegetation from the design area, land leveling, materials selection which included water, cement, sand and gravel.. The recommended Tank dimension (Length X Width X Height of 17m X 17m X 1.37m) for scheme incorporated. Tank is backfilled with near by soil. The water stored during night is most beneficially utilized for 6 hr since morning for the command area at the tail of the water course instead of design discharge of tube well of 10 LPS (during day time) for the whole area which was not possible otherwise.
