This article points to the need for a wastewater forum based on a management plan put forth in the UK. It considers two main case studies used in the development of the asset management decision support system: Sustainable Water industry Asset Resource Decisions (SWARD) and, in particular, the way in which sustainability has been included in the decisions regarding investments using a multi-criteria approach based on environmental, social, technical, and economic supporting indicators(Journal of Environmental Engineering 2008). Water UK, the trade body for all United Kingdom water service providers, originally developed a set of 25 indicators to measure progress towards “environmental” sustainability.
A wide range of tools are currently being applied to assess sustainability within the urban wastewater sector. Many of these can advance the assessment of urban wastewater projects by utilizing a multidisciplinary and integrated process. Best practicable environmental option (BPEO), using best available technology (BAT), the use of life-cycle assessment (LCA), practical minimum energy requirements, whole life costing (WLC), ecological footprinting, integrated environmental impact assessment (IEIA) and strategic environmental assessment (SEA) wider stakeholder participation is specified in the European Union’s SEA directive and the water framework directive (WFD). The structured plan shows that involvement is essential to deliver water systems that are “bought into” by communities which is also promoting economic growth and jobs. In addition, institutional and governance systems need to support good decision making by being adaptable and flexible.
Problems when devising sustainability criteria include the fact that they must encompass all aspects of human and natural systems if they are to truly relate to sustainability, and that they have disparate and incommensurate units of measurements. (Journal of Environmental Engineering 2008). The papers bring to light some cons including the efforts that are to be needed to restructure existing systems. The breakdown into a categorical overview shows the economic, environmental, social, and technical needs and outcomes following the SWARD directions. This is perhaps even more important if these services are to be provided adequately to those in the world with the greatest need _WHO/UNICEF 2006_.
