UK Public Sector Contracts & Tenders

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.

Tender for the provision of a Lifting Equipment Framework. This agreement is based on two Lots, comprised of 'The supply of Lifting Equipment' and 'The installation (and supply) of specialist Lifting Equipment'.

The Framework Agreement will cover the manufacture, supply, delivery, off-loading, installation guidelines, testing, technical support and (where applicable) disposal requirements of Polyethylene Pipes & Fittings in various sizes (as per the specification in schedule 5 of the framework document), for water applications, wastewater applications, water network applications and wastewater network applications. The material must conform to water industry standards for supply of material which will come into contact with potable water.

The supplier will engage in a service contract, focused on providing Leakage Detection in line with the Industrial Emissions Directive (IED). EA BAT guidance dictates that the scope for LDAR is sources of leakage of Volatile Organic Carbon (VOC’s) including methane. (Biological waste treatment: appropriate measures for permitted facilities - 11. Emissions control - Guidance - GOV.UK) The following type of assets are included but not limited to the LDAR scope; · Double membrane roofs (air blower vent) · Roof and cover fixings · Pressure relief valves and vents · Feeding and digestate separation units · Gas pipes · Conveyors and presses · Compressor · Combined heat and power plant (methane slippage) · Gas upgrading plant · Reception storage · Digestate storage · Pits and sumps, for example condensate pits Testing Method The Bioresource and Energy Services team require surveys to detect fugitive emissions of Volatile Organic Compounds (VOC’s) and other substances to air including methane. The LDAR survey methodology must fully comply with EA guidance Biological waste treatment: appropriate measures for permitted facilities (2024) Section 11.9 - Leak Detection & Repair and currently utilise the Optical Gas Imaging (OGI) hand held camera method to enable visualisation of gas leaks with quantification of emission rate and emission concentration.
