AB - The operation of pump systems in water distribution systems (WDS) is commonly the most expensive task for utilities with upto 70% of the operating cost of a pump system attributed to electricity consumption. Optimisation of pump scheduling could save10-20% by improving efficiency or shifting consumption to periods with low tariffs.Due to the complexity of the optimal control problem, heuristic methods which cannot guarantee optimality are often applied.To facilitate the use of mathematical optimisation this paper investigates formulations of WDS components. We show that linearapproximations outperform non-linear approximations, while maintaining comparable levels of accuracy.
