Meet the Finalists: Most Innovative Use of an Existing Technology
The 9th Water Industry Achievement Awards, organised by WWT and WET News, celebrate and reward outstanding innovation in the UK water industry. The awards are presented in 13 categories and will be given out at a gala dinner on Tuesday April 21st, 2015 at the Hilton Birmingham Metropole, Birmingham.
Each week before the awards, we are placing a different category shortlist in the spotlight. This week, we look at Most Innovative Use of an Existing Technology.
The shortlisted finalists in the Most Innovative Use of an Existing Technology category are:
Dwr Cymru Welsh Water and APEM Ltd for the use of digital aerial surveys to map the impact of water temperature changes on aquatic life in the River Towy. The surveys provided crucial data for protecting the river’s population of shad, and removed the need for extensive engineering works to a dam which would have cost Dwr Cymru Welsh Water around £10M.
e5 Alliance with Severn Trent for the “Bagel” Acid Phase Digester (APD). A collaborative effort from the project team developed an innovative solution for Severn Trent which saw two sludge tanks being combined into one structure, the Bagel APD. This technology was installed at three Severn Trent sites increasing green energy by 23% across the sites; major components were manufactured off-site and capital cost was reduced by 30% without any compromise on performance.
South West Water Delivery Alliance (H5O) for its work at Kingsbridge Sewage Treatment Works. The team used an activated biofilter – an improved version of the trickling filter – to reduce the nitrogenous load discharged from the works and help meet the terms of a new total nitrogen discharge permit. The filter is lower maintenance than the alternatives, minimises the use of flammable methanol and does not require expensive critical instrumentation.
Northumbrian Water Group for its use of sewer level monitoring in its SCADA system, combined with rain radar data, to provide effective monitoring and management of combined sewer overflows. The data was used to enhance the NWG website and give customers access to real-time information on bathing water quality.
Orchard Watercare Ltd and Atlas Water Harvesting for its gravity-fed rainwater harvesting system for buildings. Rain catchers incorporated into roof tiles feed a water storage tank in the roof space, and water is then gravity-fed to the appliances in the building. As pumps are not required to move the water, the system consumes no electricity making it the most sustainable form of rainwater harvesting available.
Perceptive Engineering and United Utilities for its Lost Opportunity KPI Report. This project developed a system that calculates the financial impact of losing critical data in a wastewater treatment plant, and displayed this cost live on the SCADA screen in the control room. The system allows operators to appreciate the lost value and to schedule maintenance correctly.
South West Water, NRW and the University of Portsmouth for its use of the ‘Chemcatcher’ passive sampler, in combination with an anion exchange receiving disc, to monitor acid herbicides in river catchments. The method allows for efficient passive sampling which can greatly reduce the need for expensive and frequent spot sampling.
