"The technology is a bit costly, but has better life. We will conduct a feasibility study on it," Irrigation Minister Manas Bhuniya told reporters here after a presentation by ArcelorMittal engineers.
Stating that such technology has been used in Karnataka and Andhra Pradesh, Bhuniya said that he would discuss the matter with Finance minister Amit Mitra.
Replying to a question, Bhuniya said that the state government was also planning to introduce a sewerage treatment plant to filter polluted water of canals falling into the Hooghly or any major river.
A detailed project report (DPR) would soon be prepared, Bhuniya said after a meeting with Urban Development and Municipal Affairs minister Firhad Hakim.
