    "description": "United Utilities is developing its statutory Drainage and Wastewater Management Plan (DWMP28) in accordance with government guidance published in 2025. The DWMP sets out how United Utilities will plan for, and maintain, a resilient and sustainable drainage and wastewater system over a minimum 25 year planning horizon, taking account of current and future risks, pressures and uncertainties.\nThe DWMP28 considers how the drainage and wastewater system can continue to operate effectively in the face of increasing external pressures that threaten long term resilience, including in particular:\n•\tPopulation and customer behaviour, increasing household wastewater demand and placing additional pressure on sewer networks and wastewater treatment capacity;\n•\tDevelopment, including the growth of specialist developments such as data centres, which can generate additional wastewater or altered effluent characteristics from cooling processes, creating localised challenges for network and treatment capacity;\n•\tClimate change, resulting in more frequent and intense rainfall events that place increasing pressure on sewer networks, wastewater treatment works (WwTWs) and receiving environments.;\nTaking these pressures into account, United Utilities is progressing risk‑based assessments alongside future scenario analysis to understand emerging risks to wastewater network capacity, WwTW capacity and environmental performance across the planning period. We are now progressing the options development and appraisal stage of DWMP28 to identify interventions that could mitigate these risks and deliver best value outcomes.\nWhile United Utilities has developed an initial range of potential options internally, we understand the importance of considering a wide range of solutions and working collaboratively with external stakeholders. To ensure opportunities are not overlooked, we are seeking to engage with the market and other organisations to identify alternative or complementary options that could be evaluated alongside those developed internally.",

We are particularly interested in proposals that support improved management of drainage and wastewater at a catchment scale.\nWe are open to the promotion of options across the range of risks addressed within the DWMP. Examples of potential third party options can be found in Appendix A include, but are not limited to:\n•\tCustomer‑side options: measures to manage demand from domestic or non‑domestic customers, including water efficiency, behaviour change and source control approaches;\n•\tSustainable Drainage Systems (SuDS) and surface water management options: measures to reduce surface water entering the sewer network, such as attenuation, SuDS and natural flood management;\n•\tSewerage network options: interventions to optimise or enhance network performance, including operational improvements, storage and conveyance solutions;\n•\tTreatment and catchment management options: catchment‑based interventions delivered in partnership to manage water quality risks (e.g. diffuse pollution or nutrient management), alongside engineered or hybrid solutions to improve treatment performance and environmental outcomes.\nProposals may be brought forward by a range of organisations, including:\n•\tLandowners or land users within the United Utilities region whose activities influence drainage or environmental performance, including opportunities for catchment based interventions;\n•\tDesign organisations offering services or technologies that could deliver demand or capacity benefits;\n•\tDelivery organisations capable of implementing relevant interventions;\n•\tOperators able to support the ongoing operation of such solutions.\nIt's also worth noting that, as part of water resources planning and the development of our Water Resources Management Plan (WRMP), we have undertaken a similar process of identifying options to, for example, increase our water supply or help us reduce demand for water.\nIf you'd like more information about our water resources planning, please contact us at water.resources@uuplc.co.uk.\nOrganisations/individuals wishing to submit a response can do so here (Appendix C provides a template to the form):\nUU Call For Options - DWMP 28 (https://forms.office.com/Pages/ResponsePage.aspx?id=X-qE_dKs_E2bcqu10WhTEE-LkwWTnWtHn6Jyy2o8ampUMzVOV0U2MDRIRk42N0gwOUpXQjhPVFg1NyQlQCN0PWcu)\nIf an organisation/individual is unable to submit by email, then a hard copy of the response template should be posted to the following United Utilities address:\nDrainwage and Wastewater Manegement Plan Manager,\nHaweswater House,\nLingley Mere Business Park,\nLingley Green Avenue,\nGreat Sankey,\nWarrington,\nWA5 3LP\nNo other documentation should be submitted at this stage.\nPlease complete the response form above as fully as possible but note where the required information cannot be provided, we will be happy to work with respondents to fill in any gaps after submission.\nInterested parties should note the following indicative timescales and process associated with this Prior Market Enagement Notice (PMEN). These timings are provided for guidance only and may be refined as the DWMP28 programme progresses.\n•\tAll options will be subject to consistent screening and selection criteria at a number of stages, in the same way as options developed by United Utilities are\n•\tNo option identified will be implemented until 2028 at the earliest\n•\tThe PMEN deadline is 12:00 on 12/06/2026.\n•\tThe options appraisal stage will assess the whole‑life costs and whole‑life benefits of each feasible option, alongside consideration of its environmental impacts. This appraisal provides further screening against environmental requirements and enables options to be ranked on a cost‑benefit basis. The costs considered within the appraisal include:\ni.\tCapital costs, including initial investment and any ongoing maintenance or replacement requirements over the life of the option;\nii.\tOperational costs, including fixed annual costs (such as reservation or standing charges, expressed in £/year) and variable or volumetric costs (expressed in £/megalitre);\niii.\tEnvironmental and social costs, including both fixed and variable impacts where applicable;\niv.\tCarbon costs, calculated from estimated greenhouse gas emissions and converted from tonnes of CO₂e into monetary values.\n•\tFollowing the market engagement event, United Utilities will, wherever possible, work with respondents to fill in gaps in responses, as required, to allow screening of the options. The purpose of this screening is to ensure that only potentially feasible options progress to be developed further.\n•\tWe will inform all respondents as to whether the option(s) they have submitted have been successful in making it through to the feasible options list for further development. We will be open and transparent about this procedure.\n•\tFor those options passed forward to the \"feasible\" options list, United Utilities will request more detailed data on each option to allow a scope of the option to be developed. The subsequent feasible list of options will be appraised in line with the DWMP framework.\n•\tThe period for submission of more detailed data will be Summer 2026.\n•\tUnited Utilities will select the more cost beneficial options as \"preferred\" options for inclusion within the Draft DWMP, and will notify all \"feasible\" options respondents accordingly.\n•\tThe programme appraisal stage will assess the benefits and costs, as well as the wider natural capital and environmental impacts of each feasible option, and apply constraints in order to develop a best value programme to be put forwards for the DWMP.\n•\tProgramme appraisal is expected to conclude by Autumn 2026.\n•\tUnited Utilities will then continue to engage with \"preferred\" option respondents  in order to confirm the inclusion of their option(s) within the Draft DWMP, including seeking to establish an \"agreement in principle\" for the option by December 2026.\n•\tThe Draft DWMP is then published in November 2027, for public consultation and subsequent modification, as required, prior to finalisation in August 2028.\nUnited Utilities will develop a list of \"unconstrained\" options. Any options submitted will form part of this list. These options are then filtered (termed \"screening\") to remove implausible options that may not actually work and deliver a benefit; respondents will be involved in discussions during this period. The resultant feasible options will be further assessed to appraise the costs of construction and operation of the option alongside an appraisal of the environmental and social impacts of the option. Once agreed with stakeholders the primary screening criteria will fall into categories and will consider:\nWhether the option can provide either a drainage benefit or manage wastewater capacity\n•\tWe will not discount any options based on uncertainty or the quantification of benefit at this stage and will work with providers of information to fully understand the option if the benefits are not clear at this stage.\nWhether the option has a high risk of failure or inherent uncertainty\n•\tWe will consider for example the engineering complexity of the option and whether it is likely to deliver the stated benefits.\nWhether the option could breach unalterable planning or environmental constraints\n•\tWe will consider for example if the option (with mitigation measures) is likely to result in significant adverse effects to designated sites or sites with significant heritage or visual amenity value.\nWhether the option could face political and customer disapproval\nWe will consider for example if the option could cause significant negative socio-economic impact that cannot be mitigated."

We will be open and transparent about this procedure.\n•\tFor those options passed forward to the \"feasible\" options list, United Utilities will request more detailed data on each option to allow a scope of the option to be developed. The subsequent feasible list of options will be appraised in line with the DWMP framework.\n•\tThe period for submission of more detailed data will be Summer 2026.\n•\tUnited Utilities will select the more cost beneficial options as \"preferred\" options for inclusion within the Draft DWMP, and will notify all \"feasible\" options respondents accordingly.\n•\tThe programme appraisal stage will assess the benefits and costs, as well as the wider natural capital and environmental impacts of each feasible option, and apply constraints in order to develop a best value programme to be put forwards for the DWMP.\n•\tProgramme appraisal is expected to conclude by Autumn 2026.\n•\tUnited Utilities will then continue to engage with \"preferred\" option respondents  in order to confirm the inclusion of their option(s) within the Draft DWMP, including seeking to establish an \"agreement in principle\" for the option by December 2026.\n•\tThe Draft DWMP is then published in November 2027, for public consultation and subsequent modification, as required, prior to finalisation in August 2028.\nUnited Utilities will develop a list of \"unconstrained\" options. Any options submitted will form part of this list. These options are then filtered (termed \"screening\") to remove implausible options that may not actually work and deliver a benefit; respondents will be involved in discussions during this period. The resultant feasible options will be further assessed to appraise the costs of construction and operation of the option alongside an appraisal of the environmental and social impacts of the option. Once agreed with stakeholders the primary screening criteria will fall into categories and will consider:\nWhether the option can provide either a drainage benefit or manage wastewater capacity\n•\tWe will not discount any options based on uncertainty or the quantification of benefit at this stage and will work with providers of information to fully understand the option if the benefits are not clear at this stage.\nWhether the option has a high risk of failure or inherent uncertainty\n•\tWe will consider for example the engineering complexity of the option and whether it is likely to deliver the stated benefits.\nWhether the option could breach unalterable planning or environmental constraints\n•\tWe will consider for example if the option (with mitigation measures) is likely to result in significant adverse effects to designated sites or sites with significant heritage or visual amenity value.\nWhether the option could face political and customer disapproval\nWe will consider for example if the option could cause significant negative socio-economic impact that cannot be mitigated."

    "description": "United Utilities is developing its statutory Drainage and Wastewater Management Plan (DWMP28) in accordance with government guidance published in 2025. The DWMP sets out how United Utilities will plan for, and maintain, a resilient and sustainable drainage and wastewater system over a minimum 25 year planning horizon, taking account of current and future risks, pressures and uncertainties.\nThe DWMP28 considers how the drainage and wastewater system can continue to operate effectively in the face of increasing external pressures that threaten long term resilience, including in particular:\n•\tPopulation and customer behaviour, increasing household wastewater demand and placing additional pressure on sewer networks and wastewater treatment capacity;\n•\tDevelopment, including the growth of specialist developments such as data centres, which can generate additional wastewater or altered effluent characteristics from cooling processes, creating localised challenges for network and treatment capacity;\n•\tClimate change, resulting in more frequent and intense rainfall events that place increasing pressure on sewer networks, wastewater treatment works (WwTWs) and receiving environments.;\nTaking these pressures into account, United Utilities is progressing risk‑based assessments alongside future scenario analysis to understand emerging risks to wastewater network capacity, WwTW capacity and environmental performance across the planning period. We are now progressing the options development and appraisal stage of DWMP28 to identify interventions that could mitigate these risks and deliver best value outcomes.\nWhile United Utilities has developed an initial range of potential options internally, we understand the importance of considering a wide range of solutions and working collaboratively with external stakeholders. To ensure opportunities are not overlooked, we are seeking to engage with the market and other organisations to identify alternative or complementary options that could be evaluated alongside those developed internally.",
