Trunk main discolouration investigations
WRc provides assessments of trunk main discolouration risk, for entire water supply systems down to individual pipes, based on PODDS (Prediction Of Discolouration in Distribution Systems) developed by the University of Sheffield.
Desk-based assessments can be followed up with field quantification of discolouration risk to determine safe operating flow rates for the main.
Trunk main conditioning can be designed to increase the operational flow envelope and reduce overall discolouration risk and increase capacity.
This is crucial when taking assets out of supply or planning for demand increases.
