Kota, Rajasthan
The Heavy Water Plant at Manuguru, Telangana is based on the bithermal hydrogen sulphide-water (H2S-H2O) exchange process. This plant with a capacity of 185 tonnes per year is the second plant based on this process, the earlier one being at Kota, Rajasthan for which the complete technology has been developed indigenously by BARC and HWB. The Manuguru site was chosen because of its proximity to Singareni coal fields and Godavari river which provide respectively large quantities of coal and water required by the plant. It was commissioned in December 1991. It is the flagship plant of Heavy Water Board.
