Energy and Water Quality Management in Water Distribution Networks Considering Variable Speed Pump and Tank Flush Scheduling
Publication: World Environmental and Water Resources Congress 2022
ABSTRACT
Concerns about reducing greenhouse-gas emissions, and the requirements for improving the quality of service to customers, have driven energy water quality management systems (EWQMS) to be one of the top priorities for water utilities nowadays. Storage tanks and pump operation/scheduling have been instrumental in driving optimal energy cost and associated energy consumption operational plans and policies. However, recent successes in water conservation have raised the subject of water age as an issue in these systems. Therefore, we need holistic solutions to manage these operations and to mitigate possible water quality issues. In this paper we employed a multi-objective simulation-optimization model to handle the challenge between energy cost and water quality management in distribution networks. Variable speed pump (VSP)/tank flush scheduling were used to manage the network. Applying the procedure on an example showed that the VSP scheduling could not find reliable solutions (in terms of water quality) without the accompaniment of tank flush scheduling.
