This paper forms an entry to the battle of background leakage assessment for water networks (BBLAWN). The proposed methodology for this problem is a sequential assessment of intervention types. In an initial stage, a diagnosis of the network is performed through simulating its hydraulic behaviour with no infrastructure or operational modifications. An optimization technique is developed to recommended improvements of a particular type, such as pipes to replace. These techniques are applied
