Cost estimation for planning and designing of decentralised wastewater treatment system

Decentralised wastewater treatment plant is a site-specific system. The different components of the system  settler , anaerobic baffled reactor , planted filter and polishing pond are planned and designed according to the treatment requirement of the wastewater generated. Average water consumption for domestic usage in India is 135 Lpcd.  80% of the water which is used or consumed for domestic purposes comes out as a wastewater. An on-site wastewater treatment plant like DWWT can be installed to treat and recycle this wastewater in order to close the loop.

Decentralised Wastewater Treatment Training Programs: Alumni

Training programmes focus on rendering improved capacities and understanding about decentralised approaches to municipalities under Centre of Excellence Programme of Ministry of Urban Development in order to establish decentralised wastewater treatment plants , particularly in un-sewered areas that would facilitate recycling and reuse of wastewater and also to general practising professionals of India and South Asia.
