Published: April 1, 2020

A water distribution network (WDN) is an indispensable element of civil infrastructure that provides fresh for domestic use, industrial development, and fire-fighting. However, in a large complex network, operation management (O&M) can be challenging. As technical initiative to improve O&M efficiency, the paradigm “divide conquer” divide original WDN into multiple subnetworks. Each subnetwork controlled by boundary pipes installed with gate valves or flow meters control volume entering leaving what are known as district metered areas (DMAs). Many approaches creating DMAs formulated two-phase procedures, clustering sectorizing, called partitioning (WNP) general. To assess benefits drawbacks WDN, we provide comprehensive review various state-of-the-art approaches, which broadly classified as: (1) Clustering algorithms, focus on defining optimal configuration DMAs; (2) sectorization physically decompose selecting installing valves. We also overview emerging problems need studied.

Assessing and modelling the water quality in a distribution system (WDS) are highly important to ensure reliable supply with sufficient quality. Owing high computational burden of such an analysis, frequently, simplifications required or surrogate models used (e.g., reducing level detail network model), neglecting significant aspects. For large (currently all-pipe) and/or recurrent simulations integrated studies, sensitivity deep uncertainty design, optimization), further increases. In this study, novel complex analysis-based approach for high-computational efficiency assessment WDS is developed comprehensively tested (R² values comparison state-of-the-art nodal qualities median 0.95 achieved).
