The software provi des an organized framework for evaluating and comparing planning alternatives or competing IAM solutions, through selected performance, risk and cost metrics . It comprises a portfolio of system metrics and network analysis tools that may also be used individually for diagnosis and sensitivity gain. The public beta release in early 2012 garnered sign ifica t numbers of users worldwide, and subsequent versions and a growing nu mber of utility deployments and pilots have been steadily confirming the potent ial of its system-based approach.

Nowadays data generated in information systems is too much, evolves too fast and is too diverse, requiring innovative information processing forms to enhance organization’s management. Driven by reporting requirements, legal obligations in developing Infrastructure Asset Management (IAM) plans and the implementation of an asset management policy inside the Group, AGS (Administração e Gestão de Sistemas de Salubridade, S.A.) designed, developed and implemented a dynamic tool to support data management and information analysis. Based on tool’s capabilities, a case study is presented, analysing rehabilitation investment impact on water systems performance. Results have shown that the relations between rehabilitation rates and non-revenue water (NRW) levels tend to normalize, being possible to establish the financial effort to reduce NRW in a given value for the case stu...

Research paper thumbnail of Results of ‘PASt21’ – the Portuguese initiative for performance assessment of water and wastewater treatment plants

Water Supply, 2012

Performance assessment of water supply and wastewater services is today a major issue. Over the p... more Performance assessment of water supply and wastewater services is today a major issue. Over the past six years, the National Civil Engineering Laboratory (Portugal) has been developing performance assessment systems for drinking water treatment plants (WTPs) and wastewater treatment plants (WWTPs). In 2009, a national field-test was launched in Portugal, ‘PASt21’, involving 27 plants (10 WTPs and 17 WWTPs). This paper presents an overview of the second generation of the performance indicator (PI) systems for the overall performance assessment of WTPs and WWTPs, the extent to which the systems were applied in the 5-year study period (2006–2010), and the aggregated results (average, median, percentiles 25 and 75, maximum and minimum) of representative PIs in each assessment group. It was concluded that all indicators are relevant, and the results show the ability of the proposed PI systems to assess the overall performance of a given treatment plant. The aggregated results are very im...
