Leakage Modeling Through Empirical Equations: An Experimental Approach

In this study, an alternative laboratory experimental approach was used to simulate leakage through round shape orifices in a complex pressurized pipe network. In order to achieve a good representation of leakage in water distribution systems, the la...

Transient Mobilisation of Replicated Biofilms

Water quality implications of transients propagating through operational networks has previously received little attention, even though there may be significant consequences. Conceptually the dynamic forces induced by hydraulic transients could mobil...

History of Water Quality Modeling in Distribution Systems

This paper traces the development of water quality modeling in distribution systems from its early roots to the present day. In the 1980s, steady state and dynamic models of water quality in distribution systems were developed. The 1990s saw the deve...

History of Optimization in Water Distribution System Analysis

The use of advanced analytical methods (i.e., system analysis) in the design and operation planning of water distribution systems (WDS) has a long history. Bolstered by the development of computing power in the 20th and 21st centuries, the use of sys...

Seasonal Temperature and Turbidity Behaviour in Trunk Mains

This paper explores the impact of seasonal temperature variations on discolouration risk in three similar operational trunk mains supplied from a single water source. Two methods have been applied over a year’s extensive monitoring to investigate the...

Variation in Peak Water Demand with Building Size: Parameters and Methods

Over time, water use in buildings has reduced due to low flow high-efficiency fixtures. The Hunter’s fixture units method of estimating peak water demand overestimates peak water demand especially for small buildings with efficient fixtures. Updating...
