The city of Dharamshala in Himachal Pradesh has a new state-of-the-art sewage treatment plant (STP) under the Smart City project.
As per the information, the plant has a capacity of treating 1.4 million litres of waste water every day. It was constructed at a cost of Rs 4 crore with the use of the Moving Bed Biofilm Reaction (MBBR) technology.
According to officials involved with the project, this is the first time that MBBR technology has been used in the country. MBBR is a highly effective technology based on a combination of activated sludge process and bio-film media. It is followed by tertiary treatment through a constructed wetland for Gamru and the adjoining areas of upper Dharamsala, the officials said.
The intended treatment levels will conform to the effluent standards laid down under The Environment Protection Act, 1986.
The officials further added that a hybrid system has been adopted to minimise electricity consumption without compromising on the quality of the treated effluent. The treatment system comprises primary treatment (a screen and a grit channel), secondary treatment through the MBBR technology and tertiary treatment with the constructed wetland technology.
