Isle of Man Water Authority


Our policies and objectives are derived from the duties placed upon us by the relevant Acts of Tynwald, and also from central Government's policy of ensuring the economic, efficient and effective provision of the services and infrastructure necessary to meet the Island's needs in terms of a wholsome supply of drinking water.

The principal objective is to provide a safe, reliable and high quality water supply to customer's homes backed up by an equally efficient customer service.

During the winter months, the Authority supplies an average of 29 megalitres of water per day to 49,000 connections, through a network of 1,734 km of mains, over an approximate area of 250 square miles. The demand for water rises to 35 megalitres per day during the summer months.
