The State government has proposed to set up seven sewage treatment plants in Bangalore to meet the city's industrial water requirement.
Minister for Medium and Large Industries Murugesh Nirani told mediapersons here on Monday that tenders had been called for to set up sewage water recycling plants on private-public partnership (PPP) model in the city.
Triveni Engineering and Industries Limited, Pune, and Thermax Limited, Pune, have shown interest in setting up the plants.
The Bangalore Water Supply and Sewerage Board has set up one such plant near Kengeri on Bangalore-Mysore Road.
Based on how this project turns out in Bangalore, a decision would be taken to set up similar plants in Mysore, Belgaum, Mangalore, Hubli and other cities, the Minister said.
Asked about water requirement of industries in north Karnataka, he said the industries had been told to take up rainwater harvesting.
On the threat by the Karnataka Small-Scale Industries Association (KASSIA) to boycott next month's Global Investors' Meet, he said the small and medium industrialists had been opposing compulsory issue of trade licences by urban local bodies.
A draft had been prepared on the issue, which would be notified soon.
