“…Moreover, the optimization goals should deserve attention. They are usually related to economic feasibility [40][41][42] or the preservation of the hydraulic reliability of the WDN [11,17]; other aspects such as pressure uniformity and water quality issues are also included. In contrast to Ferrari et al [21] and Brentan et al [43], we try not to make the original flow velocity deteriorate, especially for pipes that originally had a low flow velocity.…”

The paradigm of “divide and conquer” has been well used in Water Distribution Systems (WDSs) zoning planning in recent years. Indeed, Water Network Partitioning (WNP) has played an irreplaceable role in leakage control and pressure management; meanwhile it also has certain drawbacks, such as reduction of the supply reliability of the pipe network system and increased terminal dead water, as a result of the closure of the pipe section. In this paper, an improvement is made to the method proposed by Di Nardo et al. (2013) for optimal location of flow meters and valves. Three improvements to the genetic algorithm are proposed in this work for better and faster optimization in the dividing phase of WNP: preliminary hydraulic analysis which reduces the number of decision variables; modifications to the crossover mechanism to protect the superior individuals in the later stage; and boundary pipe grouping and mutation based on the pipe importance. The objective function considers the master–subordinate relationship when minimizing the number of flow meters and the difference of hydraulic state compared to original WDS. Another objective function of minimizing the deterioration of water quality compared to original WDS is also evaluated. The proposed method is applied for the WNP in a real WDS. Results show that it plays an effective role in the optimization of layout of the flow meters and valves in WNP.

“…Thus, transforming a network operating in IWS to a CWS is the main challenge in developing countries (Vairavamoorthy et al 2008). The first step in the transition process is the division of the network into district metered areas (DMAs) (Paola et al 2014). DMAs splits an interconnected and intricate network into smaller, virtually independent sub-networks (districts) that can be better managed; each district proposes a maximum demand value, seeking to maintain homogeneity in the pressure distribution.…”

Cities in developing countries that do not consider water resources as the basis for sustainable growth usually accept intermittent water supply (IWS) as the alternative to satisfy the demand of the population. Networks designed as constant water supply (CWS) operated as IWS hinder a safe and reliable water supply, thus, feasible alternatives to return the operation to CWS are required. This paper presents a methodology based flow/pressure control to accomplish an efficient transformation from an IWS sector to a CWS, in the City of Chihuahua, Mexico. The management of pressure at sector entrance and critical supply points leads to successful improvement of service, ensuring water availability with adequate pressure at the peak of demand, as well as reducing the supply of water volume by 58% compared to the sector operated in IWS. The methodology allowed the improvement of decision-making and operating policy for the water operating agency (WOA), fixing service deficiency, avoiding the loss of water volumes, and maintaining competent management control. Nonetheless, resistance to the transition of using automation and setting the volume/pressure consumption based on reliable data persists. The change process will be successful to the extent that the WOA efficiently channels the participation of the personnel.

“…The MGGPP is motivated by applications in different fields. First, the standard approach to manage large Water Distribution Networks is to sectorize them into subnetworks called District Metered Areas (DMAs) (Paola et al, 2014). This allows to localize leakages more accurately, by monitoring the input and the output discharges for each district.…”

The Minimum Gap Graph Partitioning Problem (MGGPP ) consists in partitioning a vertex-weighted undirected graph into a given number of connected subgraphs with the minimum difference between the largest and the smallest weight in each subgraph. We propose a two-level Tabu Search algorithm and an Adaptive Large Neighborhood Search algorithm to solve the MGGPP in reasonable time on instances with up to about 23 000 vertices. The quality of the heuristic solutions is assessed comparing them with the solutions of a polynomially solvable combinatorial relaxation.
