“…Nevertheless, the head drop in any PRS is a dissipation of energy which should be converted to electric energy (Carravetta et al 2013b;Filion et al 2004;Sammartano et al 2013). Hydropower is considered a proven reliable energy resource (Lin et al 2013;Fathi-Moghadam et al 2013) and is proposed herein to recover energy within WDNs. A technical solution, combining both economic benefits and system flexibility for smaller implementations, is the installation of pumps used as turbines (PATs) (Zakkour et al 2002) within the PRSs.…”

Pressure control is one of the main techniques to control leakages in Water Distribution Networks (WDNs) and to prevent pipe damage, improving the delivery standards of a water supply systems. Pressure reducing stations (PRSs) equipped by either pressure reducing valves or motor driven regulating valves are commonly used to dissipate excess hydraulic head in WDNs. An integrated new technical solution with economic and system flexibility benefits is presented which replaces PRSs with pumps used as turbines (PATs). Optimal PAT performance is obtained by a Variable Operating Strategy (VOS), recently developed for the design of small hydropower plants on the basis of valve time operation, and net return determined by both energy production and savings through minimizing leakage. The literature values of both leakages costs and energy tariffs are used to develop a buisness plan model and evaluate the economic benefit of small hydropower plants equipped with PATs. The study shows that the hydropower installation produces interesting economic benefits, even in presence of small available power, that could encourage the leakage reduction even if water savings are not economically relevant, with consequent environmental benefits.
