Network Reliability and Resilience
Water and wastewater, electricity and gas and fuel networks carry benefits across vast distances, but also political, geological, topographical and climatological divides. The quality of life of vast swathes of the Earth’s population relies on the reliability and resilience of these systems.
MMI Engineering has extensive experience in the reliability assessment of utility distribution networks under a range of natural and manmade hazards. Our engineers have proven track record in specialised design and engineering services to mitigate such hazards and improve the overall system reliability.
Critical lifelines such as power and water transmission and distribution systems and wastewater collection systems are usually distributed over a large geographical area and traverse zones of varying geology and topography. In developed societies, such systems have been built incrementally over decades subject to evolving design and construction standards. The systems are composed of multiple components that serve various functions, such as collection, treatment, storage, transmission and distributions, and include treatment plants, production wells, pump stations, water storage reservoirs, and tanks, pipelines and aqueducts and large dams. The system components because of their function and geographic distribution are potentially vulnerable to a range of natural hazards including the effects of global climate change.
To ensure a reliable performance, all of these hazards should be mitigated in a consistent manner with due consideration to the importance and criticality of each component. A comprehensive assessment of such system requires multi-disciplinary expertise. MMI Engineering’s senior practitioners have performed multi-hazard reliability assessment of numerous water systems and possess knowledge and expertise in structural engineering, geotechnical engineering, earthquake engineering, system operations and probabilistic techniques. Such large and complex systems can be particularly vulnerable to a range of natural and man-made hazards and also the effects of climate change. To ensure reliable performance, all hazards should be mitigated in a manner consistent with the importance and criticality of each component. A comprehensive assessment of distribution networks requires multi-disciplinary expertise. MMI Engineering has the requisite expertise in structural engineering, geotechnical engineering, earthquake engineering, system operations and probabilistic techniques to enable multi-hazard reliability assessment of utility distribution systems.
