Urban Water Systems

Provision of conventional centralised water, wastewater and stormwater systems for urban municipal services has been common practice for over 100 years. These systems center around the protection of human health, ensuring reliable water supply and minimizing flooding; often with minimal consideration of the environmental and ecological impacts associated with fresh water extraction and wastewater discharge. These urban water systems are facing unprecedented challenges in this century from the emerging issues of climate variability, population growth, aging infrastructure, urbanisation and resource constraints. In this context, the current level of urban water service provision can't be provided within the existing centralised system framework, unless there is a significant increase in investment, to enlarge and rehabilitate the existing centralized systems. Water service providers and managers are therefore considering alternative and sustainable means of providing water services in this environment. Decentralised and distributed water and wastewater systems, which are planned within an integrated water management concept, are being promoted either in combination with centralised systems; or alone as the sustainable solution for urban water servicing. Current urban water systems are beginning to undergo a transition, where decentralised systems will play a major role in the long-term sustainability of these systems to meet the above mentioned challenges. However, since decentralized systems are relatively new and involve increased complexity there are wide knowledge gaps in their planning, design, implementation, operation and management, which are impeding their uptake. This paper summarises the role of decentralized systems in the transitioning of centralised systems to a more sustainable state and discusses some of the complexities in the implementation of these systems.

Abstract. Microbiology in Urban Water Systems (MUWS) is an integrated project, which aims to characterize the microorganisms found in both potable water distribution systems and sewer networks. These large infrastructure systems have a major impact on our quality of life, and despite the importance of these systems as major components of the water cycle, little is known about their microbial ecology. Potable water distribution systems and sewer networks are both large, highly interconnected, dynamic, subject to time and varying inputs and demands, and difficult to control. Their performance also faces increasing loading due to increasing urbanization and longer-term environmental changes. Therefore, understanding the link between microbial ecology and any potential impacts on short or long-term engineering performance within urban water infrastructure systems is important. By combining the strengths and research expertise of civil-, biochemical engineers and molecular microbial ecologists, we ultimately aim to link microbial community abundance, diversity and function to physical and engineering variables so that novel insights into the performance and management of both water distribution systems and sewer networks can be explored. By presenting the details and principals behind the molecular microbiological techniques that we use, this paper demonstrates the potential of an integrated approach to better understand how urban water system function, and so meet future challenges.
