Special Issue "Infrastructure Asset Management of Urban Water Systems"
Deadline for manuscript submissions: 13 July 2022.
Interests: infrastructure asset management; performance assessment; urban drainage systems: wastewater and stormwater; hydraulic and water quality parameters monitoring; hydraulic modeling; urban resilience; nature-based solutions
Interests: infrastructure asset management; urban water systems; performance assessment systems; public policies; strategic planning; water losses and energy efficiency management; water and environment.
This Special Issue of Water will focus on infrastructure asset management (IAM) of urban water systems. IAM is the set of processes that utilities need to have in place to ensure that infrastructure performance corresponds to service targets over time, that risks are adequately managed, that the corresponding costs, in a lifetime cost perspective, are as low as possible, and that asset’s value is optimized. Driven by long-term objectives, IAM embraces strategic, tactical, and operational cycles.
Our world faces challenges such as those addressed in the United Nations Sustainable Development Goals and the Paris Agreement, currently intensified by the COVID-19 pandemic. The contribution of urban water services is vital. We learned from this pandemic that we need to be prepared for the unexpected, and that flexible, robust, and autonomous services and assets can bolster that. They must become more resilient, safer, and more efficient and effective, while ensuring a good service for all in an affordable manner. Digital transition and circular economies are simultaneously opportunities and challenges.
IAM supports this transition from the current urban water systems to their aimed future state.
The Guest Editors will consider scientific and case-based papers that address the aforementioned issues, including governance, social, economic, and technical aspects.

Abstract: Ageing infrastructure are a concern for many wastewater utilities. This is accentuated with the presence of hydrogen sulfide within the sewer headspace, known to induce concrete corrosion, toxicity and odours. Some industrial effluents contain significant sulfide concentrations, however most field studies in the literature refer to domestic networks, or lab/pilot scale sulfide abatement strategies for varied effluents. Hence, the objectives of this work are: (1) To obtain data regarding the evolution of sulfides in a full-scale industrial sewer system in Portugal, receiving wastewater from a number of tanneries; (2) model their fate within the system and (3) experimentally evaluate sulfide precipitation with iron salts. Field work evidenced heavily sulfide loaded effluents, exceeding by far literature values for sewer systems. Modelling was carried out based on the AeroSept+ model, specifically calibrated to this type of effluent. Results showed the model was capable of reproducing the overall levels of sulfide in wastewater and H2S in the sewer headspace, while allowing insights into industrial discharges, originating a set of proposed interventions for sulfide abatement. This may be carried out by iron salts addition, in a ratio of 2.75:1, at existing monitoring stations. This approach was fundamental for an affordable performance assessment, under considerable uncertainty.
Title: An Enabling Environment For Asset Management Through Public Policy: The Benefits Of Standardization And Application To The Water Sector
Abstract: Water services – including urban water supply, wastewater, and stormwater services – are essential to society and critical for protecting human health and the well-being of communities. Goal 6 of the United Nations (UN) Sustainable Development Goals (SDGs) recognizes this and aims to “ensure availability and sustainable management of water and sanitation for all.” Despite progress, the UN reports billions still lack water and sanitation services, and many governments around the world face the challenge of balancing between investments in new assets, programs, and services versus providing the required funding for repair and replacement of existing assets. This paper outlines a variety of public policy instruments used to enable infrastructure asset management and support achievement of government goals and objectives, like the UN SDGs. Analytical methods utilize a survey and case studies to illustrate how governments developed or applied public policy instruments to enable asset management. It also presents outcomes, common elements, the need for and benefits of standardization.

Abstract: Performance assessment is essential to effectively evaluate and monitor the activity of water utilities, support decision making, and encourage continuous improvement. Performance assessment systems (PAS), covering several service objectives and criteria, have been successfully applied in water supply and wastewater systems. Tailored approaches focusing on the assessment of the energy use and efficiency in wastewater systems are still limited. This paper aims at the development and demonstration of a comprehensive PAS for energy efficiency, tailored for wastewater systems, incorporating criteria related to energy consumption, operation and maintenance (O&M) costs, and environmental impacts, such as untreated discharges and greenhouse gases emissions, among others. Management and control of excessive or undue inflows to these systems is specifically addressed by several novel criteria and metrics. The proposed PAS should be adapted by each utility to be aligned with the objectives of the organisation and with the implemented asset management strategy. The proposed approach and the resulting consolidated PAS are thoroughly described. Results from the application of the PAS to several Portuguese utilities are discussed. This PAS aims at contributing to a reliable and replicable process to assess energy efficiency in wastewater systems and to encourage a more rational energy management.
