Veolia's Innovative Solution

Seawater as heat rejection in a District Cooling System

The use of seawater as heat rejection can bring about higher plant efficiency and eliminate the risk of legionnaire disease. With technological innovations, Veolia's design is 10% less expensive than the tender reference design. Coupled with Veolia's best practice in O&M, an estimate of 30% lower life cycle cost can be saved,  which amounts to 85 million kWh of energy savings per year, equivalent to a reduction of 59,500 tonnes of carbon dioxide emission per annum.
