Water distribution system management

Projects

Human-Computer Optimisation for Water Systems Planning and Management (HOWS)

This project will develop new understanding of how engineering design, planning and management of complex water systems can be improved by creating a visual analytics optimisation approach that will integrate human expertise (through 'human in the loop' interactive optimisation), IT infrastructure (cloud/parallel computing) and state-of-the-art optimisation techniques to develop highly optimal, engineering intuitive solutions for the water industry.

The Nexus Game

The worldwide use of decision games, or often called Serious Games ('games that do not have entertainment as their primary purpose'), is becoming more popular and allows players/stakeholders to experience situations that are impossible in the real world for reasons of safety, cost, time or their rare occurrence.

Our research considers management strategies for providing water securely to large urban areas.

iWIDGET Project: Smart water; smart meters; smart societies (2012 - 2015)

Improved water efficiency through ICT technologies for integrated supply-demand side management iWIDGET is a European Commission project aimed at improved water efficiencies through the use of novel ICT technologies for integrated supply-demand side management. It is a project funded under the EU 7th framework Programme, which started in November 2012 and will run for 3 years.

Prepared: Enabling change (2010-2014)

Prepared: Enabling Change is a Large Scale Integrating interdisciplinary project funded by the European Commission Seventh Framework Program (EC FP7). IPCC climate change scenarios have a global perspective and need to be scaled down to the local level, where decision makers have to balance risks and investment costs.

Urban futures (2008 - 2012)

The key aim of urban futures project is to envisage the future to enable us to make more sustainable decisions today

AIA (Ashford’s Integrated Alternatives)(2009 - 2011)

The AIA project is led by CWS and aims to explore the feasibility of more integrated urban utility service provision as a potential way to improve the sustainability of urban development.

Project NEPTUNE (2007 - 2010)

The aim of project NEPTUNE, is to advance knowledge and understanding about water supply systems in order to develop novel, robust, practical techniques and tools to optimize efficiency and customer service, through dynamic control or other means.

A risk-based decision support system for WDS failure management (2009 - 2011)

The overall aim is to develop, implement, test/verify and hand over a Risk-based Decision Support System (DSS) to enable control room operators to react and remedy failures in the Yorkshire Water Services (YWS) water distribution system before they impact customers.

Water Cycle Management For New Developments: WaND (2003-2007)

The aim of the project is to support the delivery of integrated, sustainable water management for new developments by provision of tools and guidelines for project design, implementation and management.

Integrated concepts for reuse of upgraded wastewater AQUAREC (2003-2006)

Wastewater reuse presents a feasible solution to the growing pressure on Europe's water resources. However, wastewater reuse implementation faces obstacles that include insufficient public acceptance, technical, economic and hygienic risks and further uncertainties caused by a lack of awareness, accepted standards, guidelines and uniform European legislation.

Network for advanced computer technology for underground infrastructure: ACTUI (2001-2004)

The network project is half-way through its three year grant period. It has made good progress in developing and maintaining contact between academic groups researching into computer technology for the design and management of underground infrastructure for the water industry, on both the clean and wastewater sides.

Development And Testing Of Software For The Optimal Improvement Of Water Distribution Networks (1997-2003)

Development work resulted in the software programs, GAnet and GAcal, which have been used on commercial projects involving hydraulic model calibration, design of water distribution network reinforcement and rehabilitation schemes and the optimization of level controlled pumping station operation. GAcal has also been sold commercially. Current development work is aimed at integrating GAnet with OpenNet, a library of C++ classes that provide the facilities for modelling water networks.

Development and application of inverse transient analysis software (2002-2003)

An EPSRC project titled 'Inverse Transient Analysis in Pipe Networks for Leakage Detection, Quantification and Roughness Calibration' was executed jointly by Exeter University (EU, GR/M66981/01) and Imperial College (IC).

Inverse transient analysis in pipe networks for leakage detection, quantification and roughness calibration (1999-2002)

The joint project between the Exeter University's Centre for Water Systems and Imperial College is aimed at developing an integrated, inverse-transient approach to leakage detection and model calibration.

A whole life costing approach to distribution network management (1998-2001).

To promote the efficient use of resources there is a recognised need to make best use of existing infrastructure. Whole Life Costing (WLC) in combination with computational optimisation techniques has been used to satisfy this need

A methodology for improved operational optimization of water distribution systems (1998-2001)

Operational energy costs make up a substantial proportion of the annual expenses of water supply utilities. It is thus important that the operational control of water distribution systems is optimized to ensure that appropriate levels of service and reliability are met at minimum cost.

Optimal calibration and sampling design for hydraulic network models (1997-2000)

Calibration of computer models for network analysis is a regular component of the model building process. The process generally first involves a series of field tests during which pressures and flows are recorded at strategic locations in the system.

Simplification of water supply network models through linearisation (1999-2000)

The water industry in the United Kingdom spends approximately £70,000,000 per annum on electricity for pumping water supply. Similarly, almost 7% of the electricity consumed in the United States is used by the municipal water utilities.

Optimal improvement of water distribution systems using structured messy genetic algorithm (1994-1998)

The problem of choosing the best possible set of network improvements to make with a limited budget is presented as a large optimisation problem to which conventional optimisation techniques are poorly suited. A multi-objective approach is developed, using capital cost and benefit as dual objectives, enabling a range of non-inferior solutions of varying cost to be derived.

Pump scheduling in water supply systems (1995-1996)

Cost minimisation is the main issue for water companies when establishing pumping regimes for water distribution. Energy consumption and pump maintenance represent by far the biggest expenditure, accounting for around 90% of the lifetime cost of a water pump.

Benchmarks (ongoing)

A number of benchmark problems used in the urban water modelling and optimisation literature. The current benchmarks include examples of water distribution networks used by various researchers in their studies.
