Ground-breaking Ceremony of Pilot Japanese Technology for Underground Rainwater Storage

Chennai, September 6, 2017:Ceremonies to inaugurate the ground-breakingof the JICA-supported "Verification Survey with the Private Sector for Disseminating Japanese Technologies for Gap Resolution of Water Demand/Supply by Plastic Underground Rainwater Storage System"were held at the Chief Minister’s office, Government of Tamil Nadu and theState Ground & Surface Water Resources Data Centre, Public Works Department (PWD) Campus, Chennai on August24, 2017.

Hon’ble Chief Minister ofGovernment of Tamil Nadu, Mr. Thiru Edappadi K. Palaniswami, conducted the foundation stone laying ceremony ofthe Survey at his office. The ceremony was attended by Dr.GirijaVaidhyanathan,Chief Secretary to Government; Mr. ThiruS.K. Prabakar, Principal Secretary to Government, PWD;Mr. R. Jayasingh, Engineer-in-Chief (Buildings) &Chief Engineer (General), PWD, among others.  

After above function, the ground-breaking ceremonyfor theflagship survey was organized by the Government of Tamil Nadu and Totetsu ManufacturingCo. Ltd, Tokyo, Japan.Theceremony was attended by Mr. C. T. Sankar, Chief Engineer, StateGround & Surface Water Resources Data Centre, Water Resources Department; Mr. L. Chidambaram, Chief Engineer & Director,Institute for Water Studies, Water Resources Department, staff of PWD TharamaniCampus, the survey team members from Japan, among others. 

The survey aimsat constructingahighly hygienic and economically large-scale community-based rainwaterharvesting system at PWD Campus. This helps to verify the functions of thestorage of rainwater, which has been discharged in vain, so that the rainwatercould be reutilized for water supply. The salient features of Totetsu’stechnologies are thetailor-made size of the storage and short constructionperiod. JICA believes that Chennai is the perfect place for the survey since the Government of Tamil Nadu has been imposingmandatory measures for all the buildings to be equipped with rainwaterharvesting structures, which creates the suitable environment to demonstratethe system.

Speaking on the occasion, Mr. Takema Sakamoto, Chief Representative of JICA India Office,said“JICA’s Public Private Partnership (PPP) funding scheme, gives the opportunityto take up initiatives using Japanese technologies to tackledevelopment issuesthrough innovative ways.  The water issues of Tamil Nadu are a long standing developmentchallenge.In addition to traditional approaches, we should not give up oursearch for complementary means that could potentially alleviate the problem. JICAis honoured to supportTotetsu’s initiatives in collaboration with the Government of Tamil Nadu to reduce the gap between water demand and supply in Chennai, utilizing thecompany’s unique technology of rainwater harvesting. Totetsu’s technology isdifferent from the other existing technologies. Totetsu’s products have a spaciouswalk-in structure for sound maintenance.The materials utilized can be largelyprovided from Indian local sources, keeping the implementation cost at anaffordable level. JICA hopes that this pilotestablishment named ’Aqua Palace’could prove tobe useful in tackling a part of the water issues of Chennai. It is also thought to contribute to thewater sector as a durable alternative and cost effective infrastructure acrossthe State ofT amilNadu and further becoming a spearhead in over coming the water issues throughout India.”
