2008 NI Water Customer Tap Public Register

Summary results taken from Customer Taps and Authorised Supply Point by NI Water during 2008 to meet the requirements of the Water Supply (Water Quality) Regulations (Northern Ireland) 2007 as amended. Samples collected from customer taps are taken at random addresses in each water supply zone. A water supply zone is a designated area with a residential population of no more than 100,000 supplied with water by one treatment works or blended water from several works. Under the regulations, NI Water is able to analyse certain parameters which do not change in the distribution system at the supplying water treatment works as an Authorised Supply Point. The number and boundaries of water supply zones are subject to change according to operational requirements as supply sources to areas are adjusted to meet demand and infrastructure developments.
