Decentralized Wastewater Treatment Systems generally consists of a settler, anaerobic baffled septic tank, filter bed of gravel, sand, plantation beds and a pond. The remedied water available for reuse is stored in the open pond or the polishing tank. The system does not use any mechanical means and the sewage flows by gravity through the different parts of the system. As the important parts of the system work without electrical energy inputs and cannot be switched off intentionally, the system is based on the principle of low-maintenance. The system can be installed at affordable prices as all the materials used for construction are locally available. The decentralized approach for waste water treatment is an effective, efficient and affordable waste water treatment solution for small and medium sized enterprises and also for the un-served households in the developing countries. The recycled water can be used for irrigation, growing plants and other domestic use. The processed water can also be used as flush water in toilets.
Majority of the households in India defecate in the open due to the lack of proper latrines. There are many people who use community latrines and common latrines. A number of households are connected to natural surface drains and do not have access to drainage network. Thus there is an unsafe disposal of a large amount of human excreta which has a dangerous effect on public health. 75% of all surface water across India is contaminated due to inadequate and unsafe discharge of untreated domestic waste water. The quantity of waste water is increasing due to rapid mechanization, rural electrification and inadequate financial resources.
Many initiatives have been taken up by the apartments in Kochi for waste water treatment and they have yielded satisfactory results.
