JANUARY 2015 WET NEWS 3 A 'pioneering vision' docu- ment that identi es a more sustainable re- sponse to urban and rural water management throughout the South-west has been introduced by AECOM in collaboration with South West Water (SWW), the University of Exeter, the Envi- ronment Agency (EA), and local and county councils. The document,‚ Creating a Water Sensitive South West, is the result of a workshop that showcased water sensitive urban design (WSUD) as a leading approach to securing a more bal- anced relationship between water, the environment and com- munities. It also addresses the bene ts and the barriers facing the implementation and delivery of WSUD, which originated in Australia where AECOM was instrumental in its delivery. WSUD focuses on giving a greater priority to water manage- ment considerations at the A lmost 400m of very large diameter, fabricated steel and ductile iron pipework has all been complet- ed using Building Information Modelling (BIM) on the £200M project to upgrade United Utili- ties' (UU) Liverpool Wastewater Treatment Works. The work was carried out by UU AMP5 Process Alliance partner GCA, the Galli- ford Try, Costain and Atkins joint venture. BIM had to be used because any onsite cutting was forbidden due to the coating on the fabri- cated steel pipework. Therefore the installation contractors were anxious that such a large diame- ter network, o" en running to hundreds of metres with xed AECOM launches collaborative WSUD vision for South-west " Water sensitive urban design showcased for water management in the South-west. BIM gets the pipes laid points, could be laid without major on site modi cations. The project employed BIM throughout, enabling the design and construction team to install the pipework, o" en ranging from 1,600mm to 2,200mm in diame- ter, to extremely close tolerances. GCA senior civil engineer Pat- rick Wills said: "Fabricating steel pipe at very large diameters to the required accuracy is a di› cult process, starting out with accurate dimensional data and following it through with a structured checking system lead to project success." earliest stages of development and regeneration. It can reduce the impacts of climate change and population growth in the South-west's towns and cities as well as nationwide. It recognises that all elements of the water cycle are linked and provides a smarter, cost-ež ective approach to resource e› ciency and future resilience. AECOM said delivering WSUD can help to reduce Ÿ ooding through sustainable drainage systems (SuDS) that can include natural vegetation features such as wetlands, swales and rain gar- dens. It can also save water by securing new water supplies from the rain that falls on urban centres as well as create green, attractive public spaces that pro- vide new wildlife habitats and a healthier urban environment. Tony Barrett, principal con- sultant at AECOM's water prac- tice in the UK, commented: "This vision document serves as a turn- ing point in the delivery of WSUD in the South-west. There are undoubtedly challenges to the implementation of WSUD. Col- laboration, ownership and edu- cation are the crucial keys to success. "The support from South West Water, local government organisations, the Environment Agency and the University of Exe- ter is essential to the planning and management of an improved urban water cycle and our future resilience. It is this type of joined- up thinking that is critical to turn the vision for a water sensitive South West into a reality." Andrew Roantree, SWW's head of asset management, said: "There are collaborative, low- cost and natural solutions that will reduce Ÿ ood risk, enhance neighbourhoods, prolong the life of our sewers, and make much better use of the rain that falls on our towns and cities." The next step for @Ofwat into AMP7 (2020-25) is using gain-share & TOTEX as tools to explicitly encourage innovation. @daviddwr YOU WHAT? NEED TO KNOW The beneŠ ts of transitioning to a water sensitive future extend well beyond short-term improvements in water quality, flood attenuation and reduced drinking water demand Working collaboratively on WSUD can reduce whole life costs Future Impacts on Sewer Systems in England and Wales shows that the e" ects of population growth, property creep and climate change will lead to a median increase of 51% in sewer flooding by 2040 By promoting its Downstream Thinking initiative, SWW will take a sustainable and integrated approach to managing urban drainage flows as far as is practicable The inlet connection chamber to the Feed Pump Station, installed between two Š xed points WET News is registered at Stationers' Hall.
