ABSTRACT

Worldwide, availability of good quality water for irrigation sector is expected to decline as the requirement of fresh water for all other sectors (domestic, industry, power, inland navigation, ecology) increases [29]. Therefore, it is greatly essential to reduce the fresh water consumption in irrigation sector by adopting efficient methods of irrigation and making reuse of waste water (WW) generated as byproduct from other sectors for irrigation. In India, WW generation from Class I and Class II cities are 38,254 million liters per day [10]. This huge quantity of WW gives opportunity for its reuse in agricultural sector to mitigate water demand for irrigation in water scares areas. Numerous groups have described future issues that must be addressed to ensure water quantity, quality, security and controlling emerging contaminants and health risk with protection of environment. There is an urgent need to focus on integrated management of WW use to ensure sustainability of water quality and quantity for future generation [26].
