Addressing water incidents by using pipe network models

Author: Yoyo, Sonwabiso ; Page, Philip R ; Zulu, S’Bonelo ; A’Bear, Frances Date: May 2016 It is now widely accepted that, although infrastructure problems in the electricity sector are currently the demanding crisis in South Africa, another commanding crisis looms on the medium-term horizon: deteriorating water infrastructure, and ...

The benefits of remote real-time pressure control in water distribution systems

Author: Page, Philip R Date: Nov 2018 The additional benefit of a recent highly optimal technique which keeps the pressure low and constant at a remote location, above the conventional technique, is discussed. The former technique is called remote real-time control (RRTC). The ... Read more
Deriving nearshore wave climate along South African coast

Author: Rossouw, M ; Rautenbach, C ; Page, Philip R ; Harribhai, Jatin Date: Apr 2015 The present study addressed aspects of the highly interrelated study area of coastal safety and vulnerability, climate change and setback lines for South African coast. A medium resolution numerical wave analysis was undertaken, in the form ... Read more
Parameter-less remote real-time control for the adjustment of pressure in water distribution systems

Author: Page, Philip R ; Abu-Mahfouz, Adnan MI ; Yoyo, Sonwabiso Date: Sep 2017 Reducing pressure in a water distribution system leads to a decrease in water leakage, decreased cracks in pipes, and consumption decreases. Pressure management includes an advanced type called remote real-time control. Here pressure control ... Read more
Pressure management of water distribution systems via the remote real-time control of variable speed pumps

Author: Page, Philip R ; Abu-Mahfouz, Adnan MI ; Mothetha, Matome L Date: Aug 2017 Low and constant pressure can be maintained throughout a water distribution system by setting the pressure at remote consumer locations and using the pressure to control the speed of a variable speed pump (VSP). The prospect of incorporating ... Read more
Real-time adjustment of pressure to demand in water distribution systems: Parameter-less P-controller algorithm

Author: Page, Philip R ; Abu-Mahfouz, Adnan MI ; Yoyo, S Date: Aug 2016 Remote real-time control is currently the most advanced form of pressure management. Here the parameters describing pressure control valves (or pumps) are changed in real-time in such a way to provide the most optimal pressure in the water ... Read more
Real-time dynamic hydraulic model for potable water loss reduction

Author: Abu-Mahfouz, Adnan MI ; Hamama, Y ; Page, Philip R ; Djouani, K ; Kurien, A Date: Aug 2016 South Africa is a water scarce country with limited water resources and steadily growing water demand. Unacceptably high water losses and non-revenue water threaten our water resource security as well as the financial viability of municipal ... Read more
Real-time dynamic hydraulic model for water distribution networks: steady state modelling

Author: Osman, Muhammad S ; Yoyo, S ; Page, Philip R ; Abu-Mahfouz, Adnan MI Date: Sep 2016 It is known that South Africa is a water scarce country which has been recently been experiencing erratic weather conditions resulting in a constrained water supply. Renewed focus has been placed on water conservation. This study seeks to ... Read more
Real-time dynamic hydraulic model of water distribution networks

Author: Abu-Mahfouz, Adnan MI ; Hamam, Y ; Page, Philip R ; Adedeji, KB ; Anele, AO ; Todini, E Date: Mar 2019 The impact of climate change and increasing urbanisation throughout the world has forced water utility managers to increase the efficiency of water resources. Reduction of real (or physical) water losses plays a crucial role in improving the ... Read more
Robustness of parameter-less remote real-time pressure control in water distribution systems

Author: Page, Philip R ; Abu-Mahfouz, Adnan MI ; Piller, O ; Mothetha, Matome L ; Osman, Muhammad S Date: Jun 2017 One way of reducing water leakage, pipe bursts and water consumption in a water distribution system (WDS) is to manage the pressure to be as low as possible. This can be done by adjusting a pressure control valve (PCV) in real-time in order ... Read more
The sensitivity of a water distribution system to regional state parameter variations

Author: Page, Philip R Date: May 2018 The sensitivity of a pressurised water distribution system (WDS) to state parameter variations is studied. A novel local regional sensitivity analysis (LRSA) approach is introduced which applies the same change to a collection of parameters, ... Read more
Smart optimisation and sensitivity analysis in water distribution systems

Author: Page, Philip R Date: Dec 2015 Parameter uncertainty in water pipe network models are studied using newly developed simplified mathematical notions. These enable studies to be done using public domain software, including EPANET. The results obtained can be easier to use ... Read more
Solving management problems in water distribution networks: A survey of approaches and mathematical models

Author: Bello, O ; Abu-Mahfouz, Adnan MI ; Haman, Y ; Page, Philip R ; Adedeji, KB ; Piller, O Date: Mar 2019 Modern water distribution networks (WDNs) are complex and difficult to manage due to increased level of urbanization, varying consumer demands, ageing infrastructure, operational costs, and inadequate water resources. The management problems ... Read more
A survey on data imputation techniques: Water distribution system as a use case

Author: Osman, Muhammad S ; Abu-Mahfouz, Adnan MI ; Page, Philip R Date: Nov 2018 The presence of missing data is problematic in most quantitative research studies. Water distribution systems (WDSs) are not immune to this problem. In fact, missing data is an inherent feature of a WDS. There are various techniques and methods ... Read more
