PODDS IV

PODDS IV proposal

With the increasing uptake and use of the PODDS tool as part of operational planning strategies within consortium water companies, an updated users guide to the PODDS Model and Epanet Manual (2009) is included here.

Following a proposed years extension to the project to facilitate collection of regeneration data, revised project objectives were submitted.

DOCUMENTS

STW 21" Cast Iron Satnall Trial Report (January 2013) including PODDS predictive modelling from January 2012.

WW Odcombe to Compton Durville May/June 2012 - Data collected from the Odcombe to Compton Durville trunk main indicate that there exists a discolouration risk that correlates with operator experience. Monitoring of turbidity is shown to be useful, but may also be misleading as monitoringsuggests significant settling of material. Report includes PODDS modelling.
