2014 NI Water - Customer Tap Results

Results taken from Customer Taps by NI Water during 2014 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 population of no more than 100,000 supplied with water by one treatment works or blended water from several works. 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. To preserve our customers' anonymity, only the postcode is given for each sample and not the individual addresses.
