Abstract

A computer-implemented method (100) for determining a configuration (1*) of a water distribution network (1), comprising the steps of: • providing (110) a hydraulic model (1b) of the water distribution network (1) in a base configuration where the given leak (1a) is isolated; • providing (120) an inventory of available bypass components (4), wherein installation and/or usage of each bypass component (4) is associated with a penalty value (4a); • providing (130), for each customer (3) of the water distribution network (1), a penalty value (3a) that is associated with supply interruption of this customer (3) during isolation of the leak (1a); • determining (140), based on the inventory of available bypass components (4), bypass connections (4#) between junctions i and j in the water distribution network (1), additive penalty contributions (5+) for installation and/or usage of such bypass connections (4#), and subtractive penalty contributions (5-) for reconnection of customers (3) to a water source (2) by virtue of the bypass connections (4#); • setting up (150), for each such pair (i,j), at least one equation (6), said at least one equation (6) in at least the flow qij through the bypass connection (4#) and the switching state sij of the bypass connection (4#) stipulating that, of the conditions: ∘ the difference hi - hj between the head hi at junction i and the head hj at junction j shall be dependent on the flow qij through the bypass connection according to a given continuity function Δhij(qij), and ∘ the flow qij shall vanish, at least one condition is satisfied; • optimizing (160) for a set of flows qij and switching states sij that fulfils the system of equations (6) while carrying a low overall penalty; and • determining (190) the obtained set of flows q ij ∗ <img class="EMIRef" id="66088dc1-6eb3-4129-a886-fef0ba8b70ec-ia01" /> and switching states s ij ∗ <img class="EMIRef" id="66088dc1-6eb3-4129-a886-fef0ba8b70ec-ia02" /> as the sought configuration (1*) of the water distribution network (1).
