This paper discusses the development of a methodology and software tools aimed at
assisting management decisions in order to provide acceptable performance at a
minimum cost over the whole life of the sewerage system. Whole Life Costing (WLC)
approaches have been shown to offer an ideal platform to provide investment and
operational management tools that take account of the timing of interventions, system
behaviour and performance all within a sensible economic and engineering framework.
The need for such a methodology and the requirements for its useful implementation
are introduced first. The paper then describes how research collaboration between the
UK Water Industry and two UK research centres (Centre for Water Systems at Exeter
University and Pennine Water Group at Universities of Sheffield and Bradford), and
supported by the UK Engineering and Physical Sciences Research Council grant,
resulted in an innovative, practical and auditable methodology with associated tools for
better proactive management of ageing and rapidly deteriorating sewerage systems.
