Jersey Water has two separate water pipe networks; one for the rainwater and the other for the clean water. The pipe networks all meet at the treatment works at Handois and Augrès.

Network

From the treatment works, the clean water goes in underground pipes and is sent directly to the taps at your home or school or to one of five Treated Water Storage Reservoirs located in St Helier, Trinity and St Lawrence. The storage reservoirs in St Helier and St Lawrence send water to all of the homes located below sea level (the south and east coasts), whilst the storage reservoir at Trinity sends water to homes the higher areas (north coast, west and south west of the island).

Capacity

The average demand for water in Jersey is around 19 megalitres per day – which is about 8 Olympic sized swimming pools full of water. That’s a lot of water!
