New Modularity-Based Approach to Segmentation of Water Distribution Networks |

AbstractComplex and/or large size water distribution networks (WDNs) require the division of the hydraulic system into modules to simplify the analysis and the management tasks. In the modern science of networks, the modularity index has been proposed to detect communities, i.e.,groups/clusters of nodes characterized by stronger interconnections. The modularity index is a measure of the strength of the network division into communities and it is maximized to identify them. Therefore, the division into modules of WDNs, also named segmentation, could be performed by using the modularity index as metric to identify cluster of nodes. Nevertheless, modularity index needs to be revised considering the specificity of the hydraulic systems, which are infrastructure networks. In fact, the division into modules for infrastructure networks, although it can be based on the identification of clusters of nodes, is not aimed at investigating network features. Differently, the aim is the practical issue of simplifying s... |

Scheduling Renewal of Water Pipes While Considering Adjacency of Infrastructure Works and Economies of Scale |
Journal of Water Resources Planning and Management |
10.1061/(asce)wr.1943-5452.0000062 |
|

Much research effort has been dedicated to the development of optimal strategies for rehabilitation and/or replacement of water mains. Some of the methods are intended for high-level planning of groups or cohorts of pipes, while others address low-level scheduling of individual water mains. This paper focuses on the latter aspect. An approach is proposed for the efficient scheduling of individual water mains for replacement in a short to medium predefined planning period and subject to various budgetary constraints. This approach also accounts for economies of scale considerations as well as harmonization with other known infrastructure works. A multiobjective genetic algorithm scheme is used as a tool to search a vast combinatorial solution space, comprising various combinations of pipe replacement schedules. |

Taking the β€_x009c_Wasteβ€_x009d_ Out of β€_x009c_Wastewaterβ€_x009d_ for Human Water Security and Ecosystem Sustainability |

Humans create vast quantities of wastewater through inefficiencies and poor management of water systems. The wasting of water poses sustainability challenges, depletes energy reserves, and undermines human water security and ecosystem health. Here we review emerging approaches for reusing wastewater and minimizing its generation. These complementary options make the most of scarce freshwater resources, serve the varying water needs of both developed and developing countries, and confer a variety of environmental benefits. Their widespread adoption will require changing how freshwater is sourced, used, managed, and priced. |

Diagnosis of the ageing of water pipe systems by water quality and structure of iron corrosion in supplied water |
Water supply |
10.2166/ws.2013.006 |

To develop a method for screening ageing of water supply systems by analysing the supplied water9s quality, water samples were collected from a water treatment plant, a delivery pump station, two distribution reservoirs and two feed pipes along a water pipe system. Principal component analysis of the water was conducted. In the first principal component, many elements exhibited high factor loadings, whereas the major contributor for the second principal component was iron (Fe). The unlined steel pipe, which was beyond its working lifetime, had a significantly high Fe content in suspended solids. X-ray absorption fine structure (XAFS) analysis showed differences in the abundance ratios of Fe 3 O 4 and Ξ± -FeOOH among the sampling points. It was concluded that the concentration and speciation of Fe in supplied water can be a useful index for detecting the ageing of pipes. |
