An optimal replacement-design model for a reliable water distribution network system
A municipal water distribution system is a network of underground pipes, usually mirroring the city street network, that connects water supply sources such as reservoirs and water towers with demand points such as residential homes, industrial sites and fire hydrants. These systems are extremely …

Comparison and Simulation of a Water Distribution Network in EPANET and a New Generic Graph Trace Analysis Based Model
… method was used to solve a simple looped network, and the hydraulic solutions were compared. It was determined that all three solution methods predicted flow values that were very similar. A different, more complex looped network from the solution method comparison was simulated using both …

The viability of using the stormwater ponds on the Diep River in the Constantia Valley for stormwater harvesting
Harvesting stormwater to supplement water demands has attracted a growing interest in South Africa as concerns over the security of the country's water supply increase. Whilst stormwater harvesting has been shown to offer a viable alternative water resource, there are often concerns about its …

Expert systems for disaster forecasting warning recovery and response in water resources management
… forecasting, warning, recovery, and response in water resources management require the application of knowledge from a diverse range of domains. Identifying the appropriate approach necessitates integrating rules and requirements from these knowledge domains in such a way that the operational …

Evaluation of water distribution system monitoring using a combined simulation-optimization approach
… to assess monitoring strategies for a drinking water distribution network. Multiple simulation trials of contamination events were used to create input data for an integer optimization problem. A network model, based on the Blacksburg, VA water distribution system, was used as the basis for a …

Analysis and design of an in-pipe system for water leak detection
Leaks are a major factor for unaccounted water losses in almost every water distribution network. Pipeline leak may result, for example, from bad workmanship or from any destructive cause, due to sudden changes of pressure, corrosion, cracks, defects in pipes or lack of maintenance. The problem of …

Development of an Electromagnetic Sensor for in Pipeline Inspection and Asset Management for the Water Industry
In the UK, the Water Services Regulation Authority (OFWAT), estimates that for all the water and sewage companies there was over 3,365 Ml/d (megalitres per day) of water leakage in the reported period 2010 and 2011, which was still at 3094.21 Ml/day in the 2013 review. Leakage estimates do not …

Advanced computational techniques for pipe burst detection and localisation in water distribution networks
Pipe bursts cause a considerable loss of treated water, increase the risks of environmental contamination and are a health hazard for the end-user as they can create a passage for contaminants to enter water distribution networks (WDN). Identifying pipe burst locations will help water service …
