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.
