United Utilities Laboratory Services require a courier service for the transportation of samples from sites across the Company to the central Laboratory at Lingley Mere (Warrington) on a daily basis. It is a requirement of OFWAT (The Water Services Regulation Authority) that the Company constantly undertakes analysis of water/waste water samples from various sample points throughout the North-West Region. Water Quality Officers, Network Owners, Wastewater Operatives, Trade Effluent Officers, Agricultural Advisors and Project Staff obtain the samples requiring analysis. Samples are left at drop off points for collection by the dedicated courier in a refrigerated van. Samples need to be transported under refrigerated conditions to ensure that they are maintained at a temperature of between 2 and 7 degrees centigrade. It is a requirement to maintain evidence that this has been achieved to enable United Utilities to adhere to regulatory requirements with respect to the transportation of accredited samples under the Environment Agency's Monitoring Certification Scheme (MCERTs), Drinking Water Test Specifications (DWTS) and ISO 17025. On collection, the courier takes the samples to a Sample Registration Centre (SRC) or directly to Lingley Mere Laboratories Sample Reception. An additional dedicated courier service is then required to operate between the SRC's and the Laboratories at Lingley Mere, where required. Consignment Notes or Delivery Notes detailing the sample load carried and all other required information to the Laboratory at Lingley Mere are part of the hand-over procedure at the SRCs and the Laboratory. These are currently in paper form, the Company would like to move this to an electronic format, where reports should consist of (minimum requirement): • Sample bottle barcode number • crate barcode number • vehicle registration • collection date and time • collection location • time samples dropped off • location of sample drop off Route optimisation will also be a requirement of the tender, with bidders expected to demonstrate how routes will be optimised to ensure efficiency, reliability, and timely delivery of samples while maintaining required temperature controls. Detailed dates and milestones will be share in the tender documentation. Deadline for CoPQ submission: 10/03/2026

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. The 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: • Population and customer behaviour, increasing household wastewater demand and placing additional pressure on sewer networks and wastewater treatment capacity; • Development, 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; • Climate change, resulting in more frequent and intense rainfall events that place increasing pressure on sewer networks, wastewater treatment works (WwTWs) and receiving environments.; Taking 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. While 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.

United Utilities is seeking to engage with the market to understand how the information can help drive the next strategy for all pump applications and spares supporting new and legacy kit.

United Utilities requires a framework supplier to provide 6 monthly routine, MCERTS‑compliant sampling, laboratory analysis and reporting for 24 Odour Control Units (OCUs) across 11 Industrial Emissions Directive ‑ permitted wastewater sites. Odour Control Units (OCUs) are treatment systems, and the associated assets are installed and operated by United Utilities as part of its AMP8 and AMP9 environmental obligations set out by the Environment Agency to capture and treat odorous and corrosive gases before they are released to the atmosphere.

The Company is inviting bidders to participate in this tender for the provision of activities to support a water efficiency programme aimed to provide services to customers to reduce water consumption and subsequently the achievement of business performance commitments (as outlined in the introduction). The programme consists of the provision of: • Water home audits for domestic customers including finding and fixing leaks; installation of water devices and provision of behavioural change advice. All leak repairs and fitting of devices should be completed at the time of the audit • Provision of an online water survey to allow customers to assess their current water consumption and identify ways to save • Provision of water saving devices for the water audit programme and for use at UU water saving events (Flow regulators, buffaloo bags, tap aerators and more). • Water business audits including finding and fixing leaks; installation of water devices and provision of behavioural change advice. All leak repairs and fitting of devices should be completed at the time of the audit

The Bioresource and Energy Services team require non-intrusive tank capacity and sediment assessments of Anaerobic Digesters using Lithium chloride as a trace element to comply with Environmental Permitting (England & Wales) Regulations 2016 implementing the Industrial Emissions Directive (IED) every 5 years, which takes an integrated approach to controlling pollution to air, water, and land from industrial activities. We require the supplier to develop methodology to determine the effective volume of an anaerobic digester over a short period of testing time. The effective volume should be calculated from the lithium concentration once it reaches a steady and consistent level. The calculation for effective volume should be based on the dose of lithium chloride added, the concentration of lithium, and the background concentration established before the test is initiated. The results of the data should establish the following, and be presented within a report: Mixing efficiency Hydraulic retention time (HRT) Short‑circuiting or dead zones Sediment/grit accumulation The lithium chloride is to be dosed into each digester’s feed line, or other suitable position. Prior to the dosing of lithium chloride, initial samples should be taken from each digester in order to establish the background lithium concentrations. Samples should be taken from designated sampling points, identified during a pre-test site visit.

United Utilities Water Limited is procuring a single integrated framework for Tankering, Industrial Cleaning and Water Sludge Cake services across its water, wastewater, network and bioresources operations. The framework will replace existing fragmented legacy arrangements and provide a compliant route to market for planned, reactive and emergency operational services. The services include the collection, movement, transport and discharge of wastewater, sludge, sludge cake, solids and associated materials; industrial cleaning of operational wastewater, network, treatment and bioresources assets; and the collection, haulage, transfer and operational spreading of waterworks sludge cake and liquid sludge. The framework is expected to be split into three lots: Lot 1 Tankering Services, Lot 2 Industrial Cleaning Services, and Lot 3 Water Sludge Cake / Water Sludge Services. Suppliers admitted to the framework will be assessed as meeting United Utilities’ minimum technical, operational, commercial, health and safety, environmental, transport and compliance requirements. Admission to the framework will not guarantee work. Specific operational requirements will be allocated through separate call-off competitions, which will determine the Active Call-off Suppliers for relevant service areas, regions, asset types and capacity requirements. Other approved framework suppliers may be used for back-up, resilience, overflow, emergency or continuity requirements where Active Call-off Suppliers cannot meet demand.
