WATER PAGES
a hydraulic model simulator and localised surge analysis tool to quickly detect changes in pressure. The platform offered near real-time monitoring of all datastreams, allowing the health of each stream to be tracked and reported.
Xylem’s smart platform achieved the following highlights in the first phase of the project:
■ Leakage reduced by 32% in highly instrumented DMAs with high intensity sensors and smart meters
■ Visible leaks decreased by 57%
■ Reliability and maintainability activities and CO2 cut by 41%.
Pump station performance - Wymondham, Norfolk
Anglian Water is targeting net zero operational emissions by 2030. Some 6% of Anglian Water’s carbon emissions are from their vehicles. The adoption of new technologies that assist both in reducing carbon and quantifying it, to qualify that improvement, is seen as key to net zero.
Wymondham pumping station in Norfolk had been troubled for a significant number of years. The station takes both foul and storm infiltration and there were frequent reactive attendances to site due to pump blockages, which presented a flood risk to customers, adjacent road and near the river.
The station required two cleaning visits each year, particularly problematic because of the depth of the wet well, with the added challenge of the station being located in an open public area. Xylem worked with Anglian Water’s asset improvement delivery team in May 2018, replacing one of the existing 2016 pumps with a single Flygt Concertor N6020 Intelligent pump, along with a Xylem control panel, fitted with an XPC - extended performance control - system.
The one existing pump set was configured to run only if the level rose to the assist level. During the trial, the manual sump cleaning was extended to 12 months. The station was monitored by Anglian Water for 15 months, and in October 2019, it was completely upgraded to a dual Concertor pump and XPC system.
Anglian Water continued to monitor the station for performance and wet well cleanliness. Successful outcomes included:
■ No reactive visits to site due to pump blockages in the four years from the installation of the Concertor pumps
■ Impeller wear was measured after two years with minimal wear – no adjustment required
■ Reduction in consumption of fuel associated with transport as a result of reactive site visits, manual sump cleaning and electrical savings equated to an 84% reduction in CO2- equivalent.
These are just two of many examples of successful collaborative projects, which are supporting water companies’ environmental and net zero commitments. Others, including the technologies Xylem is implementing within its own company and the work it is doing to support communities, can be seen in its Sustainability Impact Report.

Systemiser partners with Heliot Europe:
IoT improves legionella detection
Heliot Europe, a UK and European Sigfox operator and independent IoT network operator and solution provider, has partnered with Cistermiser for the development of its LinkThru Temperature Monitoring Unit (TMU) devices. These TMU devices have been designed to connect to Heliot’s Sigfox-0G network for the Internet of Things. They are used by building owners, facilities managers or maintenance professionals to monitor water flow and temperature in water systems, in an effort to reduce the risk of legionella. Anecdotally, installing 250 TMU units within a water monitoring system saves organisations 27,000 litres of water and around £225 per year. Managing this issue is rife across many settings including offices, hospitals, care homes, restaurants, and stadia.
Established over 40 years ago, Cistermiser is a manufacturer and supplier of products and solutions for the treatment and cost-effective management of water. Its LinkThru TMUs are compact, easy-to-install, scalable, and have been designed to
