The Wastewater – A Problem of Integrated Urban Water Management
2013
Abstract In order to live the man uses various generating resources through waste products his work. Use of water resources causes many types of wastewater, depending on the type of household consumption, industrial or city. Integrated management of water resources represents practical ways in which sustainable development is achieved in the field of water, including wastewater management, and is also the responsibility of all interested parties: the state, local communities, users, operators and NGOs waters. The present study shows the role and the importance of integrated management of urban water. The steps to be followed in establishing wastewater management are trying highlighting new …
A management and optimisation model for water supply planning in water deficit areas
2014
Summary The integrated water resources management approach has proven to be a suitable option for efficient, equitable and sustainable water management. In water-poor regions experiencing acute and/or chronic shortages, optimisation techniques are a useful tool for supporting the decision process of water allocation. In order to maximise the value of water use, an optimisation model was developed which involves multiple supply sources (conventional and non-conventional) and multiple users. Penalties, representing monetary losses in the event of an unfulfilled water demand, have been incorporated into the objective function. This model represents a novel approach which considers water distri…
Opportunity Costs of Ensuring Sustainability in Urban Water Services
2011
This paper assesses technical performance in the water industry in the Southern European region of Andalusia, while accounting for sustainability in the management of water. This allows the opportunity cost of producing sustainability to be evaluated. Given the low cost of raw water in Spain in relation to the estimated opportunity cost of saving this natural resource, wasting water becomes a profitable strategy for utility managers from a private perspective. However, this managerial strategy has a huge social cost in an area of Europe where the sustainable management of water is a pressing need. The conclusion is that environmental policy aimed at discouraging this wasteful behaviour is u…
Rainwater harvesting in urban areas of developed countries. The state of the art (1980-2017)
2020
Many urban areas suffer from water scarcity although paradoxically, a local source such as rainwater is mostly treated as a risk rather than a valuable resource. This change of paradigm is included in the 'integrated water resources management' and 'demand management' approach. The aim of this research is to identify and analyse studies that explore subject matters concerning rainwater in the integrated management systems of water resources into developed countries. The research methodology consisted in a literature review (from the 1980s to 2017) of territorial studies that examine rainwater harvesting in urban areas of the developed countries. To this end, a bibliometric analysis has been…
