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.

Toilets in aircraft do not flush with water; suction removes the waste into a collection bin below. When one flushes the toilet, it opens a valve in the sewer line, and the vacuum in the line sucks the contents out of the bowl and into a tank. Since vacuum does all the work, it uses very little water or the blue sanitizing liquid to clean the bowl.

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.

Investing in sanitation and hygiene is not only about saving human lives and dignity; it is the foundation for investing in human development, especially in poor urban and peri-urban areas.

Discharge of untreated sewage is single most important cause for pollution of surface & ground water since there is a large gap between generation and treatment of domestic wastewater in India. The problem is not only of adequacy of treatment capacity but also operation and maintenance of treatment plants.

In the US Midwest Municipality, wastewater is being treated and recycled to save enough potable water to supply 7,000 homes and to manufacture biofuel to run cars.
