Research is currently being conducted as part of the AQUAREC project, with the objective being the development and validation of design principles for water reuse systems. To achieve the project objective, simulation and optimisation software for integrated water reuse systems need to be developed. A water reuse system is likely to have many possible design options: type and degree of treatment, number and location of treatment plants, number and location of pumps/pumping stations, number, size and location of storage tanks, layout and size of distribution pipe network. These elements are all linked, to give multiple interactions and a very large number of design combinations. A hydraulic/process simulation model has been developed and is described, which will be used in combination with an integrated optimisation engine to allow a range of design possibilities to be explored. The model includes a computational module for wastewater treatment trains, a computational/optimisation module for reclaimed water distribution system, and a knowledge base. The computational modules are used to calculate the performance of userdefined reuse system alternatives, utilizing the information contained in the knowledge base that includes rules for generation of treatment trains, design, cost and evaluation criteria information.
Reclaimed water projects typically include construction of new or upgrades to a municipality’s treatment systems to treat wastewater to the required quality level, and construction of distribution systems for reclaimed water. A water reuse system is likely to have many possible design options: type and degree of treatment, numberand location of treatment plants, number and location of pumps/pumping stations, number, size and location of storage tanks, layout and size of distribution pipe network. These elements are all linked to give multiple interactions and a very large number of design combinations, even for apparently small systems. The complexity associated with planning of water reuse schemes is therefore very high due to a very large number of design combinations possible, and establishes the need for use of a decision support systems (DSS) to aid in the planning process. A DSS for Water Treatment for Reuse with Network Distribution (WTRNet) is currently being developed within the AQUAREC project on Integrated Concepts for Reuse of Upgraded Wastewater, under the Fifth European Community Framework Programme. The DSS provides an integrated framework for evaluation and optimisation of treatment and distribution aspects of water reuse, and will be used to achieve the ultimate project aim of the development the design principles for water reuse systems. This paper describes the current progress on the development of the DSS — the simulation and optimisation models for water reuse systems — and discusses the direction in which the development is heading. This is preceded by a brief summary of a literature review of DSS in water reuse, covering the treatment and distribution aspects of reclaimed water.

The combined hydraulic/process simulation model presented here provides a comprehensive framework for analysis of infrastructural aspects of water reuse systems, including the integration of distribution and treatment elements, and assessment of feasibility of decentralised water reuse systems. The developed simulation model overcomes limitations of currently available decision support tools by: (1) providing a framework for analysing decentralised treatment schemes, (2) allowing the user as much flexibility as possible in generating and evaluating treatment trains, (3) providing some useful guidance and starting points to the user for evaluation of treatment alternatives, and (4) incorporating an optimisation routine for least-cost sizing of the treatment schemes distribution system. The simulation model forms the basis for the development of the WTRNet package that will also incorporate optimisation routines for synthesis of treatment trains and the topology of the distribution network to form a complete DSS for integrated water reuse schemes. The complete DSS will be made available, most likely as a commercial product, following the completion of the AQUAREC project in March 2006.
