Design of water supply and sanitation scheme is based on the projected population of a particular city, estimated for the design period. Any underestimated value will make system inadequate for the purpose intended; similarly overestimated value will make it costly. Change in the population of the city over the years occurs, and the system should be designed taking read more

The life expectancy of a facility or piece of equipment is determined by wear and tear. The complete water supply project read more
