Pipe corrosion is a major cause of water quality complaints by customers, but how often is the water itself responsible for causing it? Water companies now place their customers’ experience of their water supplies at the very heart of their business. The use of Outcome Delivery Incentives (ODIs) has incentivised improvements to water quality both at the treatment stage and at the customers’ taps.
The UK water industry has resolved to minimise water quality complaints, particularly the ‘red-water’ complaints linked to corrosion of pipes. Water companies routinely assess the impacts of flow and pressure changes in the networks on water quality, and invest large sums to reduce these impacts. But what about the effect of the treated water quality on the pipes that make up the networks and cause the discolouration in the first place?
Could optimising final water chemistry help reduce complaints more efficiently through maintaining pipe integrity, reducing troublesome blockages and preventing expensive pipe failures?
MWH, now part of Stantec, Lisa Barrott explores the tests and conditioning for ensuring drinking water is non-corrosive.
