For residential communities, institutions, and independent houses, there are companies that offer smaller sewage treatment systems.
Awareness about sewage treatment plants is improving in the State and there are about 150 companies that install sewage treatment plants, according to Kannan Pasupathiraj, managing director of Klaro India.
He told The HinduProperty Plus recently that since 2008, it is mandatory in the European countries for residential and non-commercial structures that are not connected to the main sewers to have suitable treatment systems.
Residents here, who are environment-conscious, and do not want the houses to be connected to the main sewer transit system can go in for individual sewage treatment plants.
Klaro India offers smaller sewage treatment plants on build-operate-transfer model, rental basis and a system that is hybrid of both.
One plant has come up in Chennai and is to be commissioned soon.
In Coimbatore, it has installed six to seven plants in hospital, domestic and industrial premises. Since the ground water level is low in Coimbatore region, residents can treat the waste water, use part of it and allow the rest to recharge the ground water level too, he suggested.
These plants are not designed for centralised operation in a city or town.
These can be installed in independent houses, small neighbourhoods or institutions, he said.
