Jersey Water

The island of Jersey is approximately 120 square kilometres. Jersey Water treats and supplies the population of around 95,000.

Once treated, water is transferred to five treated water storage reservoirs located in St Helier, Trinity and St Lawrence. In addition, the company operates a RO desalination plant at La Rosière, which plays a vital role in providing an alternative water source for the Island, and when necessary augmenting natural water resources which are predominantly surface derived.
