PODDS III FINAL REPORT

Transfer Report - Laboratory Investigations into Processes Causing Discoloured Potable Water - a report presenting data from a temperature controlled test loop facility at the University of Sheffield written by Rebecca Sharpe as part of her Doctoral research program.

Trunk main cleaning project undertaken by Northumbrian Water on their Southern Trunk Main used a PODDS concept approach with flow increases based on predictive modelling using parameters transferred directly from those obtained from Severn Trent Water Strelley trunk main. Early data from hydroclams and using actual flow data clearly supports the PODDS approach and the diligence of NWL in achieving the required flow increases. PODDS modelling of this data using the transferred parameters highlights the potential of PODDS in maintaining the integrity of these critical components of water distribution systems.

CCWI conference, Sheffield 2009: copy of the paper and presentation by Jan Vreeburg (KWR) titled "Origin and behaviour of particles in drinking water transport networks" in which he presents the theory of turbophoresis, the movement of particles from high turbulent to low turbulent zones that could help explain the development of material layers. The paper also presents data from flushing of two trunk mains, used to support this theory. The data however demonstrates classic PODDS material mobilisation and this has been roughly modelled using standard parameters and data presented in the paper. Further data required to complete modelling.
