Intermediate and advanced asset management tools and techniques are deployed where they add real, demonstrable value to the decision making process. The maturity of asset management within Marlborough District Council is dependent upon a number factors - skills available; size, complexity and value of the infrastructure; experience and culture of staff and the risk management appropriate to the asset. The Council recognises there is an element of diminishing returns between the effort required to collect and analyse data and the subsequent improvement in decision making. The stormwater infrastructure networks are relatively small and comprehensible systems. They are managed by an experienced engineering management team and skilled operators. Advanced asset management techniques are employed only where it will add significant value to the current decision making process or significantly improve future forecasting. Core asset management is being developed to provide intelligence to operational managers and to ‘future-proof’ the existing knowledge base. Advanced techniques such as mathematical modelling, option identification and selection, cost-benefit and total benefit analysis, risk management techniques, asset condition grading are all regularly used within the current asset management strategy. A team within the Assets and Services department continue to collect data on asset condition, location and performance to support the asset managers. The quality of the data is systematically and continuously reviewed and improved. As the treatment processes and connectivity of the reticulation become more sophisticated network modelling and other techniques provide insights into the complex behaviour and Page 11
