PODDS - Prediction Of Discolouration in Distribution Systems
PODDS is a sustainable and cost effective strategy based on many years scientific research in collaboration with water companies worldwide to manage drinking water quality using innovative hydraulic strategies. As part of this work free modelling support tools have been developed (PODDS APP and VCDM) that are transforming how water is delivered as it passes through the huge and complex environments that are distribution systems. Proven to control discolouration and other water quality risks, the pro-active capability supports understanding of network behaviour with benefits including improved resilience, disinfectant retention, customer service and justifying operational or capital investment.
"Working with UK water companies, it has been shown discolouration can be sustainably managed by non-disruptive pro-active hydraulic conditioning. Application of the research to 2,686km of trunk mains between 2015-2020 delivered over £411m savings in operational and capital expenditure." REF 2021
The PODDS collaborative project is hugely successful in managing discolouration, saving £millions and reducing customer contacts. The models, tools, training and bespoke company support results from extensive collaboration that in turn has allowed the validation of innovative strategies and operational changes improving service and water quality.
Whilst companies can use PODDS to manage cohesive layer proceesses, seemingly random risks occur within distribution zones due to additional sedimentation processes. Research is therefore urgently needed to understand where this localised elevated material accumulation occurs so modelling tools and mitigating strategies can be developed. The PODDS group with its expertise in managing water quality is proposing just that... please read about it here.
