UK Public Sector Contracts & Tenders

This tender process is for the provision of Service, Maintenance and Repair of Analytical Monitoring Equipment. A summary of the scope and critical activities forming part of this tender is stated below. Service, Maintenance and Repair of Analytical Monitoring Equipment associated with drinking water and sewage treatment. STW and HD has a multiple OEM installed asset base, which includes but is not limited to ABB, bNovate, Endress & Hauser, Hach Lange and PPM analytical monitors. Our current asset base is in the region of 2000 analytical monitors which are spread across ~560 STW and HD sites all within the STW and HD region. Any potential supplier must have the ability to service, maintain, and repair all Analytical Monitors across the whole of the STW and HD region on both waste water and clean sites. This will also include management of the end-to-end process including scheduling, procurement of spares, replacement monitors, technical support, and callout. The potential supplier will also be required to carry out other activities such as Final Effluent chamber cleaning to ensure Final Effluent Analytical Monitors being serviced and maintained, are always providing accurate data. The Framework is expected to be awarded for an initial 3 years, with a further 5 x 1 year of options. Monitors in scope but not limited to; • Aluminium Monitors • Ammonia Monitors • Dissolved Oxygen Monitors • Final Effluent Monitors • Flow Cytometry • Fluoride Monitors • Iron Monitors • Nitrate Monitors • Nitrous Oxide Monitors • Phosphate Monitors • Turbidity monitors Analytical Monitors are serviced and maintained according to manufacturers, suppliers or STWs requirements. The current frequency of work undertaken is fortnightly, monthly, every 2 months and annually depending on the analytical monitor. The supplier will be responsible for the planning and scheduling of their own work to ensure analytical monitors are always proving accurate data. The supplier will be expected to access STW and HD eSCADA system and undertake pro-active analysis and take appropriate actions to ensure the Utilities analytical monitors are always providing accurate

Severn Trent requires a single, integrated waste water monitoring and alert platform. Relying on multiple standalone systems for different functions leads to inefficiencies, data inconsistencies, and slower decision-making. A unified solution will provide complete network visibility, enable smooth data exchange across all components, and support faster, more effective operational responses. The platform must be able to perform efficiently and accurately across our entire waste water network. Some context to this is provided below: • Population served (sewerage): 8.5 million people across the Midlands and Mid‑Wales • Number of sewage treatment works: 1,017 sites handling everything from small rural works to large regional plants • Daily wastewater transport: 3.1 billion litres carried through c.93,000 km of sewer pipes (combined and foul) The platform must combine all the following capabilities within one solution (not delivered as separate, disconnected modules): • Pumping Station Monitoring: Delivers real-time insights into pump performance across the network, highlighting inefficiencies, abnormal behaviour, or potential failures to reduce downtime and improve asset reliability. • Blockage Prediction: Uses flow and level data to identify unusual patterns that indicate potential blockages, enabling proactive maintenance before issues escalate into customer disruption or pollution. • Customer Sewer Alarm (CSA): Provides early warning alerts for customer-facing areas of the network where blockages or overflows could cause property flooding. This includes monitoring both digital and analog pressure data to detect problems before customers are impacted. • Burst Rising Main Detection: Accurately detects bursts in pressurised sewage mains to minimise pollution risk and operational disruption. • Excess Water Detection: Identifies abnormal water ingress from sources such as rivers, groundwater, or misconnected rainwater, which can lead to spills, damage, and reduced efficiency. • Network Spill Forecasting: Predicts spill risk based on rainfall, network capacity, and system behaviour, enabling early interventions to maintain compliance and reduce environmental impact. • Sewage Treatment Works Monitoring: Provides early detection of process abnormalities and compliance risks by analysing key treatment parameters and storm‑tank behaviour, enabling proactive interventions to protect permit performance and environmental outcomes. The platform must be a proven, commercially available product - not in early development or awaiting first deployment - and should have demonstrated successful results with other water companies, ideally within the UK and particularly with other WASCs. Severn Trent wish to consider products that offer the same functionality and scale as the systems in place within the business today; there will be no opportunity for ramp-up development. The platform should ensure full compatibility with Severn Trent's existing sensor fleet and seamlessly integrates with core utility systems (including SCADA, telemetry, SAP, and GIS), meeting interoperability standards to interpret data from all current sensors and network devices. Severn Trent will not consider any platforms that require new sensors to be introduced and installed. Severn Trent Water is a business that operates 24 hours a day, 7 days a week, all year round. Given the nature of this platform, Severn Trent Water are looking for a vendor who can offer enhanced software support and agreed service levels. Applicants who cannot demonstrate a suitable level of support will be rejected.
