The major impacts of Prof. Ulanicki’s Water Software Systems (WSS) team are:
1) Application in industrial practice of the original automatic hydraulic model reduction method which enabled the solving of large scale optimisation problems.
2) Introduction by UK water companies of optimised operations of their water distribution systems using optimal scheduling algorithms developed by the WSS team.
The model reduction method shortened the simulation time of water distribution network models hundreds of times, and enabled the solution of many complex search problems. The method has been applied by the WSS group to many industrial projects in the area of optimal pump scheduling and optimal pressure control; Thames Water, (2001), Anglian Water (2006), Yorkshire Water (2009); United Utilities (2009) and Affinity Water (2009 to date). It has attracted a lot of interest from commercial companies, for example, it is used routinely by OptiWater in Israel (Elad Salomons) in their projects, and is part of the software developed to operate the Haifa Distribution System in Israel (2008 to date).
3) Practical application of general pressure control schemes for steady state and dynamic control by the UK water companies.
Water Software Systems has developed variety of pressure control schemes based on time and flow modulation. The methods were applied in numerous industrial case studies, for instance: ‘Optimal pressure control for the Surbiton Zone, (2001), Thames Water and in around 20 district metering areas (DMAs) in South Staffordshire Water, during EPSRC RAIS grant (GR/S14382), (2002 – 2003).
We have developed dynamic models for pressure control valves (PRVs) and different type of controllers. The controller developed by the Aquavent Company (Mark Lock) was modelled and tested by WSS which led to its improved performance and subsequent installation at different sites, for instance at Addenbrookes Cambridge University Hospital (2011), Royal United Hospital Bath NHS Trust (2012) andHMS Drake Fleet Maintenance Base, Davenport (2012).
4) Introduction of an efficient burst detection method developed by WSS as standard industrial practice by a UK water company. Richard Burd (firstname.lastname@example.org), Asset Performance Specialist at Veolia Water in 2010:
“We are now rolling out PLaN (Pressure Loss across Networks) to 100 DMA's! This as you can imagine will involve improvements to the way we do things so that we can keep up with demand. So far we've had 100% success with the method. The first trial found 2 leaks and a school with flushing urinals at night oh and also a valve that was letting by, the second trial found 2 leaks, the third found 6 leaks and the last one found 10! So far every time we say go there they find a leak :-)”
