In fact, we take our water so seriously that we want to share the process with you, just to give you that extra peace of mind.

All water produced at our Desalination Plants is treated and re-mineralised. The product water is analysed for chemical content and bacterial purity to ensure that it complies with the provisions of the Gibraltar Public Health Act, which incorporates the EU Directive 98/83 of 3rd November 1998 regulating the quality of water to be used for dietetic purposes. The treated water is then pumped from the Plant to the Waterworks where it is either directed to the service reservoirs or to the storage reservoirs.

When a storage reservoir is full, the water is again analysed for chemical content and bacterial purity. Once the water is found to comply with our high standards it is placed in reserve storage until it is pumped to the service reservoirs. In order to ensure the bacteriological quality of the water remains within the required standard, the product water receives residual chlorination as it leaves the plant and also on transfer from storage to service reservoirs.

Gibraltar’s water distribution system is divided into districts, supplied with water from the service reservoirs. The water arriving at each district is sampled regularly and analysed to ensure that, when it reaches the consumer, it is still wholesome and complies with EU Directives. Further independent checks are carried out by the Environmental Health Department.
