Module 1
Scope of Environmental Engg. population trends resource use – effect on the balance of ecosystem and natural resources. Water supply Engineering: Rural and Urban water supply systems – water requirements – consumption for various purposes, percapita demand, factors affecting percapita demand, variations in the rate of consumption, fire demand, design period, forecasting population. Quality of water: impurities in water and their importance – water borne diseases – sampling of water for tests – analysis of water – physical, chemical and bacteriological tests – MPN total coliforms, fecal coliforms by A-1 medium. WHO and Indian standards for drinking water.
