Along with Babcock, Scottish Water has been independently assessed by business standards company BSI for the new international standard. ISO 55001 recognises Scottish Water's ability to achieve business objectives through efficient management of assets, such as water treatment works, by focusing on getting maximum value for customers from an asset at the lowest possible cost. It said achieving the standard demonstrates its commitment to making further infrastructure improvements while keeping customer bills low. Maureen Sumner Smith, UK managing director at BSI, said: "We are pleased that Babcock and Scottish Water are the first customers to achieve certification to the new international standard for asset management, ISO 55001. "It demonstrates the hard work and dedication that has gone into building a well-structured and robust approach to managing their assets. This is testament to their commitment to best practice and continual improvement and will, in turn, provide reassurance and confidence to new and existing customers." Colin Duguid, deputy quality manager at Scottish Water, said: "ISO 55001 enables us to demonstrate to customers and regulators that we've achieved a high degree of professionalism in the use of our assets across Scotland to produce clean drinking water and remove waste water safely and efficiently." uK-bASeD engineering, water and wastewater busi- ness Biwater is to construct a seawater desalination plant, water storage and wastewater facilities on Tor- tola, the largest and most populated island of the Brit- ish Virgin Islands. To help fund the con- struction Biwater has re- ceived dual tranche $43M (£26M) project financing from Barclays, backed by a 100% repayment guarantee from UK Export Finance. The works will benefit the local community for generations to come by ensuring an ade- quate and reliable supply of drinking water all year-round, along with improved sewage facilities. Also, the marine environment, which is of vital importance to the resi- dents of Tortola, will be better protected with the improved sewage treatment facilities to be provided by Biwater. Barclays acted as the Sole Advisor, Arranger, Lend- er and Facility Agent. The successful financial close of the complex trans- action relied upon substan- tial collaboration between specialist units across Barclays Corporate and Investment Bank- ing, including CAPEX Financing Solutions, Infra- structure & Project Finance and the Manufacturing, Transport & Logistics team. Biwater gets funding for desalination project norThumbriAn Water has been using innovative technology to clean a water pipe on the iconic Tyne Bridge without affecting traffic. The pipe runs the full length of the bridge, and the cleaning work is being carried out by Seymour Civil Engineering. The project, which will take four weeks to complete, is part of Northumbrian's £66M The Main Event investment programme and entails cleaning 850m of a 600mm diameter water pipe on the eastern side of the bridge. The old steel water pipe was installed in 1927 when the bridge was built, and has been difficult to clean without major disruption until the use inbrieF Scottish Water's wastewater treatment works at Tannadice and water treatment facilities at Turret, Lintrathen and Cas- tle Moffat are generating more energy than actually used. The 'self-sufficiency' is the result of using hydro power. Huber Technology has announced that it has been awarded a large order for six off coarse Screens, six off Fine Screens and four off Screenings Handling units for the largest sew- age treatment plant in Northern Ireland. KGN Pillinger has added the development of stainless steel fabrication services to its portfolio. The company said stainless steel pipework is is now being recognised by contractors and consultants as a viable option. Allvalves Online has spent the past eight months working behind the scenes with actuator manufacturer Sun Yeh. The agreement was made following a meeting with Sun Yeh and Allvalves' new German partners at the company offices in Pershore last October. Asset management recognition for Scottish Water Work on the western side of the bridge will take place later this year Pipe cleaning without traffic disruption of the new technology. By using pressure jets, the entire length of pipe will be cleaned from two locations either side of the bridge. Stuart Tilley, Northumbrian Water's project manager, said: "Our mains cleaning programme will make sure that our customers continue to receive excellent quality tap water in the future. We appreciate that the Tyne Bridge is busy and want to make sure that we keep disruption to a minimum here and throughout the programme. Providing work proceeds as planned, traffic will not be affected." Northumbrian Water will return to clean the section of pipe running along the western side of the bridge, using the same method, later this year.
