www.wwtonline.co.uk | WWT | DECEMBER 2018 | 5 KNOWING THE ROPES: PMP Utilities has completed the survey of the spillway at the Llyn Brianne Dam in the mountainous Powys countryside to determine its structural integrity and any requirement for remedial work. Due to its size and in- cline – 320m long with a 28° incline – the spillway was reached via rope access. United Utilities is building a floating solar farm on the surface of Langthwaite Reservoir. The power generated will be used to run the neighbouring Lancaster water treatment works, which supplies water to 152,000 people across Lancaster, Morecambe and Heysham. QUOTE OF THE MONTH "Of all the flood risks to which our rainy island is subject – from coasts, rivers, groundwater, sewers and surface water – it is surface water flooding which threatens more people and properties than any other form of flood risk" Environment Agency chief executive Sir James Bevan issues a warning over the need to tackle surface water flooding at the CIWEM Surface Water Management Conference Construction of Europe's first 'smart canal' scheme, which will use the 250-year-old Forth & Clyde Canal and modern technology to mitigate flood risk as well as enable significant regeneration, is underway in Glasgow. The digital surface water drainage system will unlock 110 hectares in the north of the city for investment, regeneration and development, paving the way for more than 3,000 new homes. The £17 million project, delivered by Glasgow City Council, Scottish Canals and Scottish Water, will use sensor and predictive weather technology to provide early warning of wet weather before moving excess rainfall from residential and business areas into stretches of the canal where water levels have been lowered by as much as 10cm. £40M Anglian Water has jointly awarded a £40 million agreement for leak detection products to 10 suppliers. In a change to the way frameworks are usually planned, the five-year contract runs from 2017-23, covering the remainder of AMP6 and the start of AMP7. £21M Northumbrian Water is investing a total of £21 million on two new water treatment works in Murton, Berwick- upon-Tweed, and Wooler. The works will use cutting-edge technology and processes to treat up to 12 million litres of water a day to help meet the needs of over 25,000 customers in the north Northumberland area. GOOD MONTH FOR... Clearwater Controls' DERAGGER device, which was found to cut energy consumption by up to 80 per cent, significantly reduce maintenance requirements and help to extend asset life in an independent trial delivered by the Water Research Centre in conjunction with United Utilities and Wessex Water. The DERAGGER prevents blockages in wastewater pumps by detecting the presence of rags and then temporarily reversing the pump until it is dislodged. BAD MONTH FOR Northern Ireland Water, which admitted it exceeded its powers when attempting to prohibit a wide range of activities as part of its hosepipe ban this summer. The utility implemented the ban between 29 June and 19 July, telling customers they were prohibited from carrying out a range of activities with a hosepipe, but has now accepted that the law currently only allows for the prohibition of hosepipe use in relation to watering private gardens or washing private cars.
