For the second time, the Chennai Corporation will tweak its proposal to install newly-designed toilets across the city.

Following inadequate response to the bid, the civic body has planned to lure bidders by increasing advertisement space and permit better display for advertisements on toilets.

The work on new design for the toilets is under way to suit the new requirement. The original plan was tweaked a few months ago. The civic body reduced the proposed number from the initial 5,000 to 2,000.

The toilets were to be installed in crowded areas in all 15 zones. The spots were identified, based on a survey by the civic body.

The toilets will be made of high-density polyethylene or polycarbonate sheets or an equivalent material.

The private contractor will build, own, operate and then transfer the toilets to the civic body after a stipulated period.

The rights of advertisement on toilets will be with the private agency that sets up the toilets. Under the earlier plan, the contract was to be in place for 10 years.

There have been very few responses for the project which involves construction of 2,000 facilities
