Using Predictive Modelling to Support Collection System Rehabilitation

Description:Over the past 50 years, utility master planning has been an accepted best practice for developing a utility wide, long range-resourcing plan. Traditionally, a masterplan will include a well-engineered proposed strategy along with the estimated short, medium, and long-range budgets to support the ability of the community to meet the changing requirements of growth and to ensure regulatory compliance. A good masterplan should include a forecast of both capital and O&M resources that together, will result in a cost effective and economically manner in which to meet approved levels of service. Evidence is showing however, that in the coming decades the need to reinvest in deteriorating infrastructure will place by far the largest capital demands on most of our utilities. Many communities are responding by preparing asset management plans that are at present prepared in a process that is not integrated with utility master planning. There is a risk that as long as asset management and master planning exercises remain separate, utility stakeholders will not have a clear vision about overall required levels of funding and thus it will remain difficult to obtain financially sustainable rates. This presentation will show that the utility masterplan of the future (but is really needed now) must include a fact and evidence driven process to estimate and forecast infrastructure renewal needs in association with capital demands from growth and regulatory compliance. A case study from the Resort Community of Whistler will be used to illustrate the concepts in this presentation.
