Award finalists: water projects

Water winners Sustainability and Climate Impact Award Yorkshire Water (YW) is embarking on its largest environmental programme, the 700m AMP7 Water Industry National Environment Programme (WINEP). As part of the overall WINEP, the utility is collaborating with Stantec and the Environment Agency to develop a new Integrated Constructed Wetland (ICW) near Doncaster, a first of its kind in Yorkshire. The ICW concept is designed to replicate a natural wetland while sustainably removing phosphorous through the introduction of 20,000 plants, comprising 23 different species. By eliminating the need for highenergy chemical treatment processes, the ICW project achieves a reduction in carbon against traditional solutions. YWs ambition to achieve net zero carbon by 2030 means the business cannot rely on traditional high-carbon methodologies to deliver WINEP. Considering a range of options (from catchment and nature-based approaches to end-of-pipe solutions) in parallel with adapting a risk-based approach has allowed the lowest-carbon solutions to be deployed by default. Adaptations are made after the fact if risk requirements are not met. This commitment to low-carbon solutions allows for strategic asset management decisions to be made early on, which is proving crucial to the success of the programme. The total estimated embodied carbon for schemes following this approach has shown a reduction in additional carbon of 65 per cent, along with a 53 per cent reduction in operational carbon against the traditional high-carbon solutions. As part of the WINEP programme YW has undertaken a cost benefit and technical review of 14 sites to be considered for conversion to enhanced biological phosphorus removal (EBPR), setting a new precedent for sustainable phosphorous removal practices in the industry, with eight schemes taken forward into the delivery phase. Although these waste water treatment works represent less than 20 per cent of the sites in the phosphorus programme as a whole, because of their size they represent more than 80 per cent of the population equivalent (3.1m) in the Yorkshire region. Yorkshire Water has shown commendable levels of innovation, creativity and resilience in undertaking this highly ambitious programme, and the impact it has made on the area is significant, said Louis Quartly, Asset Management Director, Stantec. The ICW concept replicates a natural wetland while removing phosphorus through the use of 20,000 plants Clifton waste water treatment works with integrated wetland design Sustainability and Climate Impact Award Transforming the Trent Valley (TTTV) is a partnership project of 18 organisations working to restore and enhance the natural and cultural heritage of the Trent Valley across 21,489ha, led by Staffordshire Wildlife Trust (SWT). Binnies was commissioned by SWT to map and value the areas natural capital assets showing the distribution of benefits provided by the areas natural environment across the landscape. Provided in an online interactive platform a first of its kind in the UK it offers the opportunity for users to explore the area (10m resolution satellite data) to see how different habitats provide benefits in different ways: carbon, air quality, biodiversity, water quality, water regulation, recreation and food production. The platform allows users to explore at will the change in habitats and the benefits they give us, said Fran Moore, Binnies Associate Natural Capital Specialist and Environmental Economist. It is really helping decision-makers, stakeholders and the public to look at the landscape around them differently. Users can click on individual areas for the benefits they provide and their value. Binnies also valued the impact of TTTV habitat restoration projects and quantified the impact of future projects in terms of carbon sequestration and biodiversity net gain (BNG). This approach has allowed us to quickly and clearly quantify the carbon and BNG impacts and benefits to clients plans, linking this to investment decision-making and achieving organisational targets, said Moore. It also quickly identifies available opportunities for nature recovery across large areas and understanding how well they deliver to multiple goals. The platform is supported by modelling of natural capital, and various options testing, in order to optimise the impact and delivery of natures recovery across large areas. It is helping our clients to enhance their own asset management planning and decision-making tools to a level that allows them to more effectively work towards their goals through prioritising investments in terms of value and impact. The platform allows users to explore the change in habitats and the benefits they give us Map showing the various habitats in the Trent Valley Corporate Transformation Award The Tarrant Regional Water District (TRWD) is a rapidly growing organisation that supplies raw water to more than two million people across North Central Texas, USA. In response to rapid population growth in the area, TRWD has doubled the number of pump stations in service since 1998. Its current project in collaboration with the City of Dallas, the US$2.4 billion Integrated Pipeline, is adding six additional pump stations and 160 more miles of large-diameter transmission line. In 2014, TWRD began implementing a new asset management programme following the ISO 55000 standard. By 2019, it had already completed the first three phases of the programme addressing both the vertical and horizontal water transmission assets, which totalled 268 miles of large-diameter pipes. Now operating entirely in-house, the programme plays a crucial role in bringing together leaders from different organisational functions through monthly asset management governance meetings to discuss strategy, staffing, performance reviews, innovation, continuous improvement and many other aspects included in the programme. This process-driven and holistic approach builds awareness at all levels and secures contributions from internal stakeholders, thus ensuring effective and consistent collaboration across all departments. The last 18 months of the programme were about transforming the business so it could address all parts of its mission, including flood control and recreation. First, the 2020-22 Strategic Plan was developed, outlining TWRDs vision and ethos, followed by its new Strategic Asset Management Plan (SAMP), which was designed to fit closely with ISO 55000 standards. Additional specialised asset management plans for each area of TWRDs work were developed, Reservoirs (R-AMP) and Floodway (FL-AMP), as well as an annual self-assessment tool related to ISO 55000. In the past year, the team has managed to make asset management part of the companys DNA, transforming the way it conducts mission-critical activities, says Rachel Crawley, Asset Management Program Lead. Our plans for the near future include incorporating asset management into all facets of our organisation for complete business transformation.

Through flexible asset management systems and careful testing, NW was able to improve and maintain both WTWs at the high operating standards required. Mosswood WTW takes its raw water from either the River Tyne or the Derwent Reservoir, both of which are vulnerable to bacteria. Both WTWs need to reduce the levels of all pathogens to comply with NWs Effective Disinfection policy, and to future-proof for any deterioration in raw water. One option was to install UV lights, but this required significant capital investment. Meanwhile, Lumley WTW also required some water quality improvements. NW looked for cost-effective innovative solutions that met the requirements of the project by engaging with the supply chain, industry bodies and academics in the field. The solution was to place smaller UV reactors on the outlet of individual rapid gravity filters (RGFs). As well as reducing operating costs, this would ensure the reactors are located in the best possible place according to industry best practice, eliminating the risk of disinfection by-products. However, because this was a new technology that had no approval from industry regulators at the time, different parties from both the scientific and managerial side of the industry would need to work together to build a new business case for the project. The reactors successfully passed the validation requirements and regulations. Thanks to the hard work of all partners involved, as well as the decision to seek the advice of third-party regulators from abroad to ensure government guidance was met, the trial process was a success and asset management governance were able to approve further funding to build the solutions at Mosswood and Lumley, said Senior Project Manager David McDonagh. Business Modelling Associates (BMA) is a leading UK-based analytics firm with a strong international client base. As part of its work with Anglian Water (AW) on BMAs Decisio solution, a Bioresources production planning platform (BPPP) was deployed that makes use of an adaptive systems modelling approach. This allows system planners to evaluate sludge distribution based on treatment site availability and forecast sludge production. Consisting of a tactical and operational delivery solution, the platform includes more than 700 sites and incorporates various modules for adaptive systems planning. In 2021, AW experienced a major outage at a treatment centre shortly before a scheduled maintenance shutdown. This coincided with a highsludge period that necessitated alternative treatment to fulfil incoming demand, and the problem was exacerbated by wet weather and a backlog of prior demand from existing sludge stocks. Because the required intervention was so complex, the outage was expected to last four to 16 weeks, which would negatively impact all areas of the business. With significant costs already beginning to accumulate, AW needed to act quickly so that this impact on the treatment works could be minimised. Having the Decisio platform already in place mitigated this impact, reducing energy losses and carbon emissions. The intervention process was structured into a 12-week view period and a one-year projection period. Solution modelling initially focused on using pre-incident projections of sludge stocks to create an early best-case estimate of the amount of offline time needed, but following a performance review it was decided that downtime duration views should be extended beyond the initial best-case scenarios by four weeks. The next phase of the programme would involve a more holistic view of the incident, with planning centred around analysing multiple potential scenarios and reducing the risk of lasting problems. Information gained during this year was compartmentalised into week-long periods to streamline stakeholder access, and the BPPP enabled all maintenance operations to be organised efficiently. The support provided by BMA to AW enabled the identification of future developments that will be incorporated to allow for even greater agility and insights in their responses to similar events in the future, said Steve Riches, AWs Bioresources Portfolio Lead. The incident has provided us with the opportunity to increase our resilience and be better prepared to face similar challenges in the future.
