The State Legislative Assembly complex, one of the capital city’s landmarks, will on Monday set a model for the State’s efforts in rainwater harvesting (RWH), with the commissioning of six RWH tanks capable of storing 15.3 lakh litres of water.

Capacity

The RWH tanks will be commissioned by Speaker G. Karthikeyan at 3.30 p.m. on Monday. The tanks are said to be the largest of their kind in the State with three of 5 lakh litre capacity, and the remaining three of 10,000 litre capacity each.

The ferro cement technology-based tanks will conserve the rainwater that flow down the roofs of the buildings in the Assembly complex.

This, in turn, will reduce water charges for the complex.

The 5-lakh litre tanks have been constructed for the Assembly Block, the Administrative block and the new museum while the 10,000-litre tanks are at the Speaker’s quarters, the Deputy Speaker’s quarters and the Secretary’s quarters.

It is estimated that the capital city, under normal circumstances, will get rain for around eight months a year, from which around nine crore litres can be saved annually through the RWH tanks. The Assembly complex, as of now, uses around 1 lakh litres daily for various purposes.

The cost of this is expected to be reduced drastically once the tanks serve their purpose.

Constructed by the Wayanad-based Society for Education and Integral Development (SEID), the RWH concept was announced on October 30 last when President Pranab Mukherjee inaugurated the Green Assembly Complex project.
