Business Models: Where there’s muck, there’s money
In the developing world, the business of sanitation is rarely considered to be a money maker. However, new developments in the productive use of human waste are opening up real opportunities for cashing in on urban wastewater and sludge. Research carried out by the International Water Management Institute (IWMI) is attempting to establish where and how such models can be made socially or ...

Realising sustainable urban water management: Can social theory help?
It has been acknowledged, in Australia and beyond, that existing urban water systems and management lead to unsustainable outcomes. Therefore, our current socio-technical systems, consisting of institutions, structures and rules, which guide traditional urban water practices, need to change. If a change towards sustainable urban water management (SUWM) practices is to occur, a transformation of ...

Role of decentralised systems in the transition of 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 ...

A mathematical approach to find long-term strategies for the implementation of resource-orientated sanitation
In the present discussion of sustainability centralised water infrastructures are exposed to new challenges, which may cause a conceptual alteration in urban water management. If technologies for closing urban water and nutrient cycles are to at least partially replace existing systems, then intensive reconstruction work becomes essential. The paper presents the development and implementation ...

Exploring the effects of domestic water management measures to water conservation attitudes using agent based modelling
The urban water system's sustainable evolution requires managing both water supply and water demand within a complete urban water cycle framework. Such an approach, however, requires tools to analyse and simulate the complete system including both physical and cultural environments. One of the main challenges, in this regard, is the design and development of tools able to simulate the ...

Modelling the urban water cycle as an integrated part of the city: a review
In contrast to common perceptions, the urban water infrastructure system is a complex and dynamic system that is constantly evolving and adapting to changes in the urban environment, to sustain existing services and provide additional ones. Instead of simplifying urban water infrastructure to a static system that is decoupled from its urban context, new management strategies use the complexity ...

Flexible engineering designs for urban water management in Lusaka, Zambia
Urban water systems are often designed using deterministic single values as design parameters. Subsequently the different design alternatives are compared using a discounted cash flow analysis that assumes that all parameters remain as-predicted for the entire project period. In reality the future is unknown and at best a possible range of values for design parameters can be estimated. A ...

An ecohydrologic model for a shallow groundwater urban environment
The urban environment is a patchwork of natural and artificial surfaces that results in complex interactions with and impacts to natural hydrologic cycles. Evapotranspiration is a major hydrologic flow that is often altered through urbanization, although the mechanisms of change are sometimes difficult to tease out due to difficulty in effectively simulating soil–plant–atmosphere ...

Is strategic asset management applicable to small and medium utilities?
Urban water infrastructures provide essential services to modern societies and represent a major portion of the value of municipal physical assets. Managing these assets rationally is therefore fundamental for the sustainability of the services and to the economy of societies. “Asset Management” (AM) is a modern term for an old practice—assets have always been managed. In recent years, ...

Looking for efficiency through integrated water management between agriculture and urban uses
Many urban water systems must cope with water scarcity and climate change and additionally they must be able to fulfil the objectives of environmental protection, efficiency and sustainability. At the end they must provide the expected level of service now and in the future horizons. Some new comprehensive approaches are assessing the total water footprint in a territory using the concept of ...

The impact of diurnal water use patterns, demand management and rainwater tanks on water supply network design
The traditional use of long-term average consumption records and “peak factors” to determine water network design criteria does not account for allotment-scale diurnal water use patterns which impact upon the dynamics of water distribution systems. The diversity of allotment-scale diurnal water use patterns directly impacts on network dynamics. Demand management and rainwater tanks are likely to ...

Augmenting Water Supply Systems
Direct use of recycled water to augment urban water supply systems entails pumping water into the distribution system or blending with the conventional supply at the water treatment plant. The recycled water needs to be treated to drinking water standards or better, including advanced treatment processes to remove trace organics and chemicals. The City of Windhoek in ...

Substance flow analysis as a tool for urban water management
Human activity results in the production of a wide range of pollutants that can enter the water cycle through stormwater or wastewater. Among others, heavy metals are still detected in high concentrations around urban areas and their impact on aquatic organisms is of major concern. In this study, we propose to use a substance flow analysis as a tool for heavy metals management in urban areas. We ...

Major urban water and wastewater systems in Minoan Crete, Greece
During the Minoan era a number of remarkable developments occurred on the Greek island of Crete which have been widely recognized. However, one of the salient characteristics was the architectural and hydraulic function of its water supply, sewerage, and drainage systems in the Minoan palaces, cities, and other settlements. It might be inferred, therefore, that Minoan master craftsmen in Bronze ...
