The toilet, constructed by Building Materials and Technology Promotion Council, a concern under the Ministry, uses cost-effective and environment-friendly construction material and technologies.

Selja said the government is planning to replicate the new toilets in several other MCD schools in Delhi and other cities, after the MCD primary school for girls at the Indian Airlines Colony, Vasant Vihar.

BMTPC officials said the toilet block uses rat-trap masonry in burnt clay bricks and fly-ash bricks instead of the usual burnt bricks. The BMTPC has used plantation wood instead of forest timber for the door shutters, angle iron door frames (instead of timber) and precast ferro cement roofing channels.

Officials said the method employed for the construction is cost-effective and will save the MCD as much as 20 per cent of the total construction cost. MCD officials added that the Urban Development Ministry has approved of the toilet block and has offered to sponsor the construction of similar toilet blocks in all MCD primary schools.

‘‘The existing toilets are in very bad shape. These toilets will be easier to clean and the height of these toilets is more accessible to smaller children as opposed to our existing toilets,’’ said an MCD official.
