Seiichiro TAKAI and Er. A. Dhanapal formally exchanged the completion documents that marked the official handing over of the pilot project.

Hiroyuki OKUI, Managing Director of Association of Rainwater Storage and Infiltration Technology (ARSIT) presented a technical paper highlighting the technology, construction of tanks using the different components, accumulation of rain water in a 6 lakh litre capacity underground tank and the conditioning (disinfecting) system and process before it is released for general public. He added that the disinfecting system converts the stored rain water as potable water and can be distributed through water ATM machine.

“Aqua Palace” – the unique plastic components specially developed by Totetsu – a Japan based company was used in the pilot project to maximize the storage and utilization levels.

S. Raja, executive engineer, WRD, said the underground storage tank was more of a composite structure, with inner walls built using imported PVC plates and pipes.

A disinfecting system has also been installed and there are plans to distribute the water to residents through a water ATM. WRD’s Taramani campus was able to store enough water for six months.
