Waste Water Monitoring & Alert Platform

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.
