Depleting groundwater levels and excessive increase in the volume of wastewater is seen as a result of recent industrial developments in urban India. Industrial wastewater recharge and water conservation have now become the need of the hour to overcome water shortages and improve groundwater levels in the country.

In this modern world of advanced techniques, sewage treatment works are considered to be one of the most popular procedures carried out to use the treated wastewater for agricultural purposes or to dispose off on to the land. The primary objective of this study is to design a Sewage Treatment System for Sri Satya Sai Urban Development Authority (SUDA) in Andhra Pradesh and studying the possibilities for usage of treated wastewater for irrigation. The study area, Puttaparthy being a pilgrim center attracts people all over the world and during some special occasions the place gets over crowded.

In the present study, an attempt has been made to evaluate the treatability of a combined tannery and domestic wastewater using lab-scale activated sludge reactor under extended aeration.

Urbanization is occurring at an unprecedented rate, particularly in developing countries, with high migration of population from rural to urban areas. As a consequence of urbanization and associated environmental impacts, the issue of providing water to growing urban population is becoming critical. Water management in the context of urban area has two components i.e.

Effects of industrial effluents on germination, growth, protein content and metal accumulation patterns in Hibiscus esculentus L. were studied. Effluent from two factories in the industrial belt of Cochin, Kerala were used to soak the seeds for germination and to irrigate the seedlings in the field after physico-chemical analysis.

Ultraviolet light kills bacteria in wastewater without the use of chemicals. This reliable and environment friendly method was used in the project Clean Isar in Germany.

The current study is on East Calcutta Wetland (ECW) which is a model for multi-use resource recovery system with activities like pisciculture and agriculture. The entire city's soluble waste is disposed into the raw sewage canals which finally drains into the shallow, flat bottom fish ponds called Bheri. These sewage fed fisheries act simultaneously for the purification process like removal of heavy metals, coliform reduction as well as fish production at a commercial scale.
