Physical investigation into the significance of ground conditions on dynamic leakage behaviour
Effective leakage models are crucial for leakage assessment and control strategies to improve the sustainability of vital water distribution, and other pipeline, infrastructure. This paper evaluates the interdependence of leak hydraulics, structural dynamics and soil hydraulics, particularly considering the significance of the soil conditions external to longitudinal slits in viscoelastic ...

An integrated system dynamics – cellular automata model for distributed water-infrastructure planning
Modern distributed water-aware technologies (including, for example, greywater recycling and rainwater harvesting) enable water reuse at the scale of household or neighbourhood. Nevertheless, even though these technologies are, in some cases, economically advantageous, they have a significant handicap compared to the centralized urban water management options: it is not easy to estimate a ...

A planning algorithm for quantifying decentralised water management opportunities in urban environments
With global change bringing about greater challenges for the resilient planning and management of urban water infrastructure, research has been invested in the development of a strategic planning tool, DAnCE4Water. The tool models how urban and societal changes impact the development of centralised and decentralised (distributed) water infrastructure. An algorithm for rigorous assessment of ...

Unpacking the energy implications of distributed water infrastructure: how are rainwater systems performing?
Drought and concern over climate change has led to the increased use of distributed water systems in Australia to supplement centralised supply systems. A literature review carried out by the Institute for Sustainable Futures (ISF) into the energy consumption of water infrastructure found that very little data on energy consumption exists, particularly for distributed systems. This paper reviews ...

Integrated sensing technologies for detection and location of leaks in water distribution networks
Water distribution networks (WDNs) are infrastructure systems that have high socioeconomic values, for which efficient operation and management are required to ensure minimal amounts of waste which can be represented in the form of leaks. Leak detection is considered as one of the challenges faced by municipalities operating WDNs because it either involves shutting down the system or requires ...

How can we ensure water security for all?
Wetlands International will be speaking about this issue at the upcoming Clinton Global Initiative Annual Meeting. The Clinton Global Initiative was established in 2005 by President Bill Clinton to convene global leaders to create and implement solutions to the world's most pressing challenges. This year’s Annual Meeting will take place on 26-29 September in New York. Water scarcity and ...

Unique technology for monitoring piped water
INTELLITECT WATER has launched a unique, highly innovative drinking water monitoring technology that will revolutionise the delivery of drinking water. The new technology monitors the quality of water in pipeline distribution networks and for the first time provides reliable data to protect the integrity of the water quality, to enhance customer satisfaction and to improve operational efficiency. ...

Water in a post-COVID world: The challenges and opportunities ahead
As we reach what is hopefully the latter stages of the coronavirus pandemic, the global water industry stands at a crossroads. It has been stress-tested by a “black swan” event that no one could have ever anticipated. It has caused primary and secondary effects that we’re only starting to understand. But one thing is clear: This is an unprecedented time to re-think our global ...

Maximizing AMI investments through broader IIoT Insight
Advanced metering infrastructure (AMI) has received a lot of attention in recent years, typically regarding customer account billing. Other AMI uses within water distribution networks, however, can play equally important roles in reducing non-revenue water (NRW). Consider these contributions of networked flow meter use for automating better insights into water distribution ...

Resilience of civil infrastructure systems: literature review for improved asset management
Infrastructure resilience has drawn significant attention in recent years, partly because the occurrence of low-probability and high-consequence disruptive events like Hurricane Katrina, the Indonesian tsunami, terrorism attack in New York, and others. Since civil infrastructure systems support society welfare and viability, continuous infrastructural operation is critical. Along protection ...

Stochastic simulation methodology for resilience assessment of water distribution networks
Water distribution systems enable social and economic development and sustain people quality of life. However, these systems face significant performance challenges including ageing, natural disruptive events, and man–made disruptions. Physical protection of networked infrastructure distributed over large geographical areas is unfeasible. A cost–effective alternative is to enhance the water ...

Graph-based approach for generating virtual water distribution systems in the software VIBe
Application of virtual case studies (VCS) is a well established technique in environmental engineering to test measures, approaches, models or software. However, preparation of VCS for an infrastructure network is a tedious task. In literature, approaches can be found which generate very simplified VCS, which are only partly comparable with real world case studies. VCS which are more comparable ...

Effects of rainwater harvesting on centralized urban water supply systems
The potential effect of widespread rainwater harvesting practices on mains water demand and quality management are investigated for three different types of urban areas characterized by different roof area to water demand ratios. Two rainfall patterns are considered with similar average annual depths but very different temporal distributions. Supply reliability and the extent of reliance on the ...

Alternatives for safe water provision in urban and peri-urban slums
In response to rapid urbanization throughout the global South, urban and peri-urban slums are expanding at an alarming rate. Owing to inadequate financial and institutional resources at the municipal level, conventional approaches for safe water provision with centralized treatment and distribution infrastructure have been unable to keep pace with rapidly growing demand. In the absence of ...

Singapore’s used water underground infrastructure to be monitored with Distributed Fiber Optic Sensing (DFOS) technology by fibrisTerre
Singapore’s Deep Tunnel Sewerage System The Deep Tunnel Sewerage System (DTSS) is a key part of the long-term Singapore’s used water system, which comprises a network of link sewers leading to two major tunnels (Phase 1 & 2) crisscrossing Singapore with three large water reclamation plants (WRP), as well as outfall pipes. DTSS uses deep tunnels to convey used water entirely by ...

Mapping Water Taps to Ensure WASH Infrastructure and Safe Drinking Water for the Entire Population of Kumba (Cameroon)
Ensuring safe and clean water for the people across Africa is one of the greatest problems on the continent. Water sources are often miles from towns and villages, so people are forced to spend hours each day simply finding and transporting potable water back to their homes. In the city of Kumba (Cameroon), displaced people settled in their farms lack safe water access, and most of them and ...

ASTM Standards Help Meet Need for Clean Water
The new ASTM Water Portal provides a single access point to standards and related information about ASTM International’s diverse committees working to protect and monitor this vital global resource. Clean and safe water is the underpinning of the quality of life for people around the world. Global economies depend on water, whether it’s to support the manufacturing of goods across ...
