MINISTER FOR MINISTRY OF SCIENCE AND TECHNOLOGY AND MINISTRY OF EARTH SCIENCES (Independent Charge)(DR. JITENDRA SINGH)
(a & b) While, there is no proposal for public private partnership to generate potable water and transport it to water deficit area like Rajasthan, presently the efforts are focused on scaling up the Low Temperature Thermal Desalination (LTTD) technology. Earlier, three LTTD plants have been successfully commissioned in the country, one each at Kavaratti, Minicoy, and Agatti islands of the Union Territory of Lakshadweep. The capacity of each of these LTTD plants is 1 lakh liter of potable water per day. It is proposed to set up a LTTD plant with a capacity of generating 2 million litres of potable water per day (2 MLD) at the Tuticorin Thermal Power Station, Tamil Nadu. Design of an offshore large scale plant is also underway.
(c & d) The cost per liter of desalination would depend on the technology used and cost of electricity which varies from place to place. According to the cost estimates made by an independent agency for LTTD technology, the operational costs per litre of desalinated potable water is about 61 paise for island based plants.
(e) Does not arise.
