Innovative Low Carbon Solution, Thames Water
Great Dunmow Water Recycling Centre, Thames Water
Location – East of Stansted Airport.
Serves – c10,000 population.
Investment Drivers – Population growth and existing treatment reliability issues.
MWH Treatment Innovative Solution – Treatment technology utilising ‘smart’ aerobic granular biomass.
Result – A low carbon solution (60% reduction in embodied carbon).
Benefits – minimised ground loadings, reduction of footprint, acceleration of delivery, maximised offsite manufacture and assembly of equipment.
Outcome – Won the award for Best Use of Technology for Carbon Reduction’ at New Civil Engineer’s Tech Fest 2018.
Facts – The £15m plant was delivered under budget and within programme.
Strategic Clean Water Security and Resilience
Melbourne Water Treatment Works is a critical strategic asset for Severn Trent
Location – Leicestershire.
Serves – c750,000 customers.
Investment Drivers – Asset age and condition, required enhanced resilience.
MWH Treatment Resilient Solution – Integrating a major 1.8m diameter bypass around a high lift pumping station, reducing impact on operations and improving customer supply security.
Result – Installation completed in a series of 16-hour windows with zero customer interruptions.
Enablers – Real time communication and total integration of team critical to success, enabled through a WhatsApp group.
Outcome – Project delivery was enhanced by use of 4D digital collaborative planning and digital rehearsals.
Facts – Totally eliminated clashes, developed detailed installation sequences, and effectively engaged Client’s operational and leadership team providing critical continuity between interim installation and operational phases.
Proactive Data Led Performance Optimisation
MWH Treatments Integrated Asset Management Team (IAM) developed an analytical platform (WANDA)
Location – Severn Trent Headquarters, Coventry.
Serves – All Severn Trent Water’s 8 Million Customers.
Investment Drivers – Large multiple source clean water network data sets requiring real time analysis and to create decision support information.
MWH Treatment WANDA Network Analytics Platform Solution – By creating visual outputs and delivering improved analysis speed we created better understanding of asset performance for Severn Trent.
Results – More accurate burst response analysis, improved resilience, optimised capital investment, more stable water quality, increased Network Interruption Solutions (reducing customer lost supply minutes).
Outcome – An optimised tailored data analytics solution, to support decisions, linked directly to client ODI performance.
Benefits –Accurate water balance tool for leakage reporting, from its ability to account for all flows through a network, functionality to download, import and view live telemetry data.
Fact – WANDA’s Balance Tool includes demand analysis, giving a live mass balance and calculated leakage rate of the water network, helping reduce leakage significantly.
Harnessing the Sustainable Power of Water
Howden Reservoir, Severn Trent
Location – Upper Derwent Valley, England.
Serves – Impounding reservoir holding 8,600 kl of water, from catchment of 20.86 km2.
Investment Drivers – Generation of 0.3Mw of renewable energy to offset power consumption.
MWH Treatment Sustainable Solution – Two redundant pipes with 28m available head used for installation of a ‘’cross flow’’ mini hydro turbine.
Result – Contributed towards Client’s Energy Generation Target of 50% of consumption by 2020.
Benefits – Location adjacent to Howden Dam carefully considered materials and the sympathetic appearance of the new turbine house. Carefully considered locally sourced larch cladding reduced cost, carbon and boosted local community economics.
Facts –High amenity value and local environment was created by including sympathetic traffic management along the mile-long single track, part of the circular route for cyclists and walkers.
Outcome – Providing many years of renewable power to the grid and just one of Treatment’s “smart”sustainability projects.
Water Supply Enhanced Resilience
Heigham Water Treatment Works, Anglian Water
Location – Norwich
Description – Serves 250,000 customers, with on average 42 Million Litres per day of water, abstracted from gravel pits or directly from river Wensum.
Investment Drivers – Ensuring supply resilience against deteriorating ground/river raw water quality.
MWH Treatment Supply Solution – Innovation centred on integration of submerged Ultra filtration membrane technology, within the existing water treatment works.
Result – The plant, the largest of its type in Europe integrated membrane technology with the reuse existing assets, yielding significant carbon saving compared to a ‘green field’ solution.
Benefits – Our 3D model used as visual medium engaged operational staff and used Virtual Reality to embed detailed end user requirements.
Outcome – Stakeholder engagement was managed through the process of ‘Constructive Collaboration’ and gave an open forum and opportunity to share ideas and common themes to improve project delivery efficiency.
Fact – This complex integration was conducted with first time hand-over to satisfied operations colleagues.
Strategic Innovation
Watchgate and Oswestry Water Treatment Works, United Utilities
Locations – Cumbria and Shrewsbury.
Serves – A combined flow of 621Million Litres per Day.
Investment Drivers – Two projects strategically released together by United Utilities to benefit from delivery efficiencies, to extend the life of existing assets and improve water quality.
MWH Treatment Innovative Solution – For both sites we incorporated innovative direct filtration technology, proven internationally, but a first at scale in the UK.
Result – In depth hydraulic modelling gave a resilient process design for specific flocculation characteristics required.
Benefits – As two of the largest treatment sites in the Clients asset portfolio our innovative solution for filter outlet control using differential pressure delivered high yield Totex savings.
Outcome – The works were constructed on live sites, with exceptional liaison with operations, completed with minimal interruptions.
Fact – These assets have delivered stable output for over 15 years.
