  • 4. Source selection of water  Cost:- the source should be such that the overall cost of the water supply project is brought down to the minimum.  Elevation:- it should be at higher level to supply water by gravity flow only  Location: the source should be near to the town or city such location require less lengths of pipes which contribute in making project economical. 4/29/2016 4
