Network water quality management

Analysis, advice and solutions from SUEZ help water utilities identify and tackle the critical factors that affect water quality in their networks. Ensuring the water distributed to customers is of the highest quality requires constant vigilance. Water treated in the UK is generally of exceptionally high quality, but ageing water distribution networks are prone to problems that can compromise the quality of water arriving at the consumer’s tap.
Helping deliver the future of water

The number and frequency of discolouration incidents is just one measure of water quality performance. Identifying which of the multiple variables are impacting water quality – pipe materials, flow, hydraulic conditions, sedimentation, or water chemistry, among others – can be complex.


By understanding and analysing these factors holistically across the network, water utilities can take proactive measures to safeguard and improve water quality and ensure customer satisfaction.
