AECOM called in for London SuDS pilot


THAMES WATER has selected Aecom as lead consultant on its Counters Creek SuDS Ret- rofit Pilot Project. The project is part of the Counters Creek Flood Alleviation Scheme, Thames Water’s largest sewer flooding alleviation scheme that is seeking to identify a long-term solution to sewer flooding in west London. Through the SuDS Retrofit Pilot Project, Thames Water is investigating how effective sustainable drainage systems can be in controlling surface water flows to combined sew- ers in the Counters Creek area. The study area com- prises 15 selected streets and


15 adjacent control streets within the London Borough of Hammersmith & Fulham and The Royal Borough of Kensington and Chelsea. From


these long-listed


streets, Thames Water has specified that Aecom devises its own criteria and method- ology to select a final three streets, as well as three asso- ciated control streets, for the SuDS retrofit pilot trials. Aecom, as lead consultant, will provide integrated servic- es including hydraulic mod- elling, planning, SuDS and landscape


design, environ-


mental consultancy, commu- nity consultation, highways


liaison and traffic manage- ment,


project management,


construction supervision and final reporting on the overall conduct of the trials and the performance of the SuDS. Shirel Stedman, project director within Aecom’s Eu- ropean water practice, said: “The SuDS Retrofit Pilot Project is an industry-leading pilot study. We are delighted to be able to apply Aecom’s leading global SuDS research and our integrated approach to water sensitive urban de- sign to help Thames Water identify a lasting solution for a potential wider roll out across London.”


MHW supports Qatar drainage work


MWH GLOBAL has become management contractor on the Public Works Authority’s (PWA) five-year Qatar Drain- age Asset Management Pro- gramme, supporting the or- ganisation’s goal in achieving world class asset and opera- tional management services. The programme is part of Qatar’s National Vision 2030

ly the Qatar Integrated Drain- age Master Plan project to identify the country’s drain- age infrastructure and water resource needs for the next 50 years.


B&V provides modelling


BLACK & VEATCH is to help manage the various functions of Dwr Cymru Welsh Wa- ter’s (DCWW) wastewater collection and transfer sys- tem. As one of six framework partners, B&V is providing wastewater modelling

Creating a more sustainable industry presents the water sector with a unique set of challenges for the future.


WWT’s fl agship event, Sustainable Water 2012 brings together over 30 industry experts to examine how water companies can deliver the sustainable outcomes needed by customers, the environment and the economy.


This must attend event features a two day programme of thought provoking plenary sessions, practical innovation workshops and interactive panel discussions will explore:


• Regulation for a fi nancially, environmentally and socially sustainable sector • What is needed for water companies to leverage sustainable outcomes in AMP 6? • Delivering water at an acceptable price • The customer’s role in demand reduction • The case for integrated water management • How to future proof your business against energy volatility • Meeting the challenge of delivering sustainable operational effi ciencies • Catchment management - a sustainable approach to water quality • Is sustainable water achievable?


Expert speakers include:


Nick Ellins President, Institute of Water


Prof. Tom Stephenson Chairman, British Water


Tony Smith Chief Executive, Consumer Council for Water


David Elliott Director of Regulation & Assets, Wessex Water


Regina Finn Chief Executive, Ofwat


Richard Flint Chief Executive, Yorkshire Water


Richard Aylard External Affairs and Sustainability Director, Thames Water


Georgina Perkins General Manager for Energy Climate & Change, Severn Trent Water


Dr. Paul Leinster Chief Executive, Environment Agency


Dr. Jerry Bryan Executive Chairman, Albion Water


Alan Sutherland Chief Executive, Water Industry Commission for Scotland


Dr. Stephen Bird Operations Director, South West Water


The impact of population growth, urban creep and climate change is placing in- creasing pressures on sewer networks. Additionally, there is a need to manage waste and stormwater drainage systems in a more sustainable way. B&V will create hydraulic models of wastewater catch- ments,


providing DCWW


with a live view of current network performance. This data will feed into Sustainable Drainage Plans (SDPs); a vital tool for deriving the utility company’s investment plans for AMP5 and beyond. Improved visibility will al- low for cost-effective invest- ment with design solutions that address limitations and optimise network manage- ment.


The benefit this provides includes identifying where surface water run-off can be reduced or eliminated from entering the sewerage net- work, since this can overload

the system and cause flood- ing. The approach marks a step change in the way Welsh Water has previously man- aged its sewer network. It supports the company’s priorities on surface water elimination and reduction (SWEAR). The framework also forms a critical com- ponent of Welsh Water’s long-term strategy to reduce surface water run-off into sewers, and decrease flooding and pollution incidents. Black & Veatch will uti- lise the expertise of its local dedicated wastewater model- ling team based in Treforest, south Wales to support the framework.


Motors supplied to Namibia


WEG HAS supplied 62 self- monitoring motors for the recently-opened


55,000m3/d www.SUSTAINABLE-WATER.co.uk Organised by Supported by 6 | WET News | July 2012


Trekkopje seawater desalina- tion plant in Namibia. The plant is the largest of its kind in sub-Saharan Africa, and is a vital water supply asset in a country where 98% of the land is considered arid or semi arid.


The WEG motors, rang-


ing from 18.5kW to 750kW, drive pumps that are con- sidered crucial to the plant’s reliable operation. Designed and built by specialist water treatment company Keyplan,


part of the Aveng Group, the Trekkopje plant converts seawater from the Atlantic Ocean into potable water for use at the large Trekkopje opencast uranium mine. The desalination process entails abstracting salt water via pipes that are placed one kilometre out to sea. The sea water is then pumped to the plant where screening and ultra filtration prepares it for reverse osmosis, a process where a membrane selec- tively retains the salt, allow- ing the desalted water to pass through.
