“…Optimisation methods have developed significantly since the 1970s. Deterministic methods used initially (Brion and Mays 1991;Carpentier and Cohen 1993;Coulbeck et al 1988a;Coulbeck et al 1988b;Lansey and Awumah 1994;Ulanicki and Kennedy 1994;Ulanicki et al 1993;Zessler and Shamir 1989) started being supplemented by metaheuristics during the mid 1990s ( Figure 4). The first of these methods introduced was a GA (Boulos et al 2001;Lingireddy and Wood 1998;Mackle et al 1995;Moradi-Jalal et al 2004;Wu et al 2014a), which was also used with modifications (Bene et al 2010;Selek et al 2012;Wu 2007) or in combination with local search methods (i.e.…”

“…Energy consumption normally incurs energy consumption charge and demand charge. Consumption charge is based on the kilowatt-hours of electric energy consumed by pumps during the billing period (Ormsbee et al 2009) and is often the only component of operating costs used in the pump optimisation problem (for example Jamieson et al (2007), Kim et al (2007), Ulanicki et al (1993)). Demand charge is usually based on the peak energy consumption during a specific time period (Ormsbee et al 2009), and often determined over a time scale much longer (weeks-months) than the time period considered for optimisation (hours-days).…”

“…This extended time can become especially obstructive when real-time control is considered. Consequently, large networks are being simplified for the purpose of optimisation (Cembrano et al 2000;Jowitt and Germanopoulos 1992;Ulanicki et al 1993), or reduced (so called reduced models) (Shamir and Salomons 2008) by applying mathematical manipulation, such as the methodology proposed in Ulanicki et al (1996).…”

Optimisation of the operation of water distribution systems has been an active research field for almost half a century. It has focused mainly on optimal pump operation to minimise pumping costs and optimal water quality management to ensure that standards at customer nodes are met. This paper provides a systematic review by bringing together over two hundred publications from the past three decades, which are relevant to operational optimisation of water distribution systems, particularly optimal pump operation, valve control and system operation for water quality purposes of both urban drinking and regional multiquality water distribution systems. Uniquely, it also contains substantial and thorough information for over one hundred publications in a tabular form, which lists optimisation models inclusive of objectives, constraints, decision variables, solution methodologies used and other details. Research challenges in terms of simulation models, optimisation model formulation, selection of optimisation method and postprocessing needs have also been identified.

“…Early research papers on this subject handle energy-efficient operation of pumps (Pezeshk et al, 1994;Ulanicki et al, 1993), possibly in combination with guaranteed supply by optimal management of water inventory in buffers (Crawley and Dandy, 1993). Nonlinearity of the objective function is an immediate consequence of the 'power term', which is a function of two main variables of the system: pump head and flow rate.…”

Modeling and Optimization of Production and Distribution of Drinking Water at VMW

We develop and discuss an operational planning model aiming at minimizing production and distribution costs in large drinking water networks containing buffers with free inflow. Modeling drinking water networks is very challenging due of the presence of complex hydraulic constraints, such as friction losses and pump curves. Non-linear, non-convex constraints result from the relationships between pressure and flow in power terms. Also, binary variables are needed to model the possibility of free inflow or re-injection of water at reservoirs. The resulting model is thus a non-convex Mixed-Integer Non-Linear Program (MINLP). A discrete-time setting is proposed to solve the problem over a finite horizon made of several intervals. A commercial solver, BONMIN, suited for convex MINLP models is used to heuristically solve the problem. We are able to find a good solution for a small part of an existing network operated by the Vlaamse Maatschappij voor Watervoorziening (VMW), a major drinking water company in Flanders.
