COMACOE receives prestigious award for 3 desal plants at Lakshadweep Islands

COMACOE is very proud to announce the receipt of award of 3 projects from NIOT for setting up LTTD (low Temperature Thermal Desalination) Plants at islands of Kadamat, Amini and Chetlet at Lakshadweep islands.

The Lakshadweep islands have an acute shortage of potable water and mostly survives on supplies from mainland. Over the past 15 years, Government has struggled to develop some reasonable solution to resolve this water crisis in the islands and after successful experiments with Low Temperature Thermal Desalination (LTTD) Plants in 3 islands (Kavaratti in 2005, Minicoy and Agatti in 2011) by NIOT, it was decided to go ahead and setup such LTTD plants in 6 islands namely, Amini, Chetlet, Kadamath, Kalpeni, Kiltan and Androth with capacity to produce approx 165,000 litres of potable water per day from sea water.

Accordingly, E-tenders (6 separate tenders) were invited by NIOT for the above 6 mentioned islands in September 2017 and LoAs were issued for 5 islands in March 2018. COMACOE bid for 4 islands and has been awarded 3 – namely, Kadamat, Amini and Chetlet.

The Contracts were signed on April 6th at Prithvi Bhavan, Delhi by NIOT Director, Dr. M.A.Atmanand and COMACOE CEO, Mr. Vivek Bansal in presence of Dr. Madhavan Nair Rajeevan (Chair, Earth System Science Organization (ESSO) and Secretary to the Government of India for Ministry of Earth Sciences (MoES), COMACOE Founder & MD, Mr. Sanjeev Rai, and other NIOT stakeholders – Dr. MV Ramanamurthy, Dr. SVS Phani Kumar and others.

The proposed desalination plants will run on the principle of Low Temperature Thermal Desalination (LTTD) that involves evaporating warm surface seawater (at about 28 degC) in a Flash Chamber maintained under Vacuum (at about 27 mbar) and consequently liquefying the resulting vapour in a Condenser. The coolant water for the condenser is drawn using the thermal gradient available in the ocean, namely using the feature of reduction of ocean water temperature with an increase in depth. A long pipe is deployed in the ocean to draw the cold water (at about 12 degC) from a distance of about 1000m from a depth of about 350-400m.


National Institute of Ocean Technology (NIOT), an autonomous body under the Ministry of Earth Sciences, and is engaged in developing technology for utilizing ocean resources in an eco-friendly manner.

COMACOE is a specialist marine construction contractor, a market leader in India for specialized, near-shore marine structures, such as sea water intake/outfall systems, effluent outfalls and diffusers, marine piling, shoreline protection, etc.
