Ground water supply

Big reserve of Ground water in the World: 0,6 % of total world fresh water compares with surface water only 0,02%Ground water has a small content of solid and organic matter, microorganism (coliforms and e coli) that more safely than surface water (river, lake, lagoon, rain).

GROUND WATER SUPPLY Positive characteristics of Ground water supply • Big reserve of Ground water in the World: 0,6 % of total world fresh water compares with surface water only 0,02% • Ground water has a small content of solid and organic matter, microorganism (coliforms and e coli) that more safely than surface water (river, lake, lagoon, rain) • Output of ground water less depend on climate conditions in local area And that time, reserve of surface water strongly depend on rain and dry seasons • Ground water distributes more largely than surface water, people can get under ground water every where • Processing treatment of ground water easy and cheaper than treatment of surface water Negative characteristics of Ground water supply • Sometime, ground water has high pollutant content: As, Fe, CaCO3, salinity; it’s necessary to set up treatment processing ground water before utilize • Ground Water has a big reserve, but safely output of ground water exploit not large, because residence time of GW about 100 years to 10,000 years • Exploitation of Ground water from sediment aquifer lays can be create subsidence → That difficult to build a big waterworks for city water supply Ground water supply Ground water supply Ground water supply Ground water supply Ground water supply Ground water supply Ground water supply Schema drinking water supply plant Schema drinking water supply plant Schema city drinking water supply Schema city drinking water supply Ground water supply Ground water supply Ground water supply [...]...Schema drinking water supply plant Schema drinking water supply plant Schema city drinking water supply Schema city drinking water supply Ground water supply Ground water supply Ground water supply
