This paper presents the integrated methodology for infrastructure asset management (IAM) developed in AWARE-P, an R&D project aimed at producing adequate and effective support tools for assisting urban water utilities in decision making and rehabilitation planning (www.aware-p.org). The proposed methodology addresses all three planning and decisional levels (strategic, tactical and operational) and follows a plan-do-check-act (PDCA)-inspired cycle. The methodology assesses the water systems and any planning solutions along the cost, risk and performance dimensions, with a variety of standardized assessment methods and models proposed for each. It differs from existing approaches in the incorporation of the entire IAM process into a single organised framework, with an integrated, long-term vision of the urban water network â looking at the infrastructure as a system, and not as a mere sum of individual assets. The paper describes the approach and illustrates its application with reference to the several business cases already undertaken. |

Sustainable water management must nowadays consider alternative water sources and the use of reclaimed water is a good candidate. Low-pressure ceramic membrane filtration is an emerging option for safe water reclamation given its high mechanical and chemical robustness with safety and operational advantages. One-year pilot studies of hybrid coagulationâceramic filtration were developed in Portugal in two wastewater treatment plants in the Lisbon metropolitan area. The results obtained demonstrated the technology's effectiveness, reliability and efficiency towards water quality, with the hybrid process consistently producing water highly clarified (monthly median <0.1 NTU), bacteria-free and with reduced organic matter content, regardless of the strong and severe variations in its intake. |

TRUST is an acronym for Transition to the Urban Water Services of Tomorrow. Just into its second year, this fourâyear European Union project consists of a consortium that is split into eight work areas (which in turn are segmented into many work packages), focusing on different aspects of the project. These eight work areas are not islands of expertise working in isolation in different countries in Europe, but cooperating and collaborating team members actively exchanging and sharing information among themselves to ensure that progress toward the end goals is ensured and expedited. |

Environmental impact analysis of chemicals and energy consumption in water treatment plants: Case study of Oslo, Norway |

This paper studies the trend in the consumption of energy and chemicals and the associated environmental impacts, for water treatment plants (WTPs) in Oslo, over the years between 2000 and 2009. The Norwegian Drinking Water Regulations stipulate that supplied water should comply with over 50 quality criteria. Abiding by the regulations and improving the water quality has its costs â economically and environmentally. Quality improvement entails, inter alia, the consumption of more chemicals, both in terms of quantity and variety, and a rise in energy consumption. In order to determine the environmental impacts of the consumption of chemicals and energy, an environmental life cycle assessment (LCA) was carried out. It was observed that the impacts of chemicals have increased dramatically after 2007, courtesy of a process upgrading at one of the WTPs. Except in the years 2004 and 2007, the impacts attributable to chemicals consumption have exceeded those due to energy consumption. Global warming is the key impact in both cases, though in the case of energy consumption, abiotic depletion and acidification are also significant. |
