Pump Station Alerting: The hidden cost of reactive pump station operations
Pump stations are critical infrastructure and when they underperform or fail, the consequences are immediate contributing to sewage overflows, flood risk, regulatory breaches, and costly emergency response. Yet across wastewater utilities globally, monitoring networks still relies on reactive intervention.
The reality is that the status quo is not free, the cost is simply less visible. By the time an alert is sent, the problem may have already started.
The Real Cost of Reactive Monitoring
Reactive pump station monitoring isn't just operationally inefficient, it's expensive. Unplanned callouts, overtime, equipment damage, fines and environmental impact all add up. Reputational risk can also occur when a sewage spill happens or an overflow event that is missed. This is an invisible cost and outlines that smarter approaches become clear to implement.
Why This Matters Now
Wastewater utilities globally are dealing with ageing infrastructure, heavier and less predictable rainfall, tighter regulations, and budget restraints. For most, the focus is on getting more performance out of the assets they already have, rather than replacing them. Modern pump stations generate a continuous stream of telemetry flow rates, wet well levels and run times. The challenge for many utilities problem is turning the existing data into timely, useful information upon which to act upon. Without context, raw data produces ‘noise’ and too much ‘noise’ leads to alert fatigue which in turn, leads to potential missed events.
With heightened regulatory pressure in the UK, wastewater utilities here have responded proactively to evolving demands. Southern Water have adopted a proactive monitoring approach and as a result, are able to glean insights and avoid missing critical asset failures.
By spotting early signs of performance issues, it helps extend asset life, cut down on maintenance costs and manage pump failure risks proactively. When you’re running large networks with a lot of pump stations, oversight over your network is essential.
The Bottom Line: Maximising outcomes
A good example of proactive network monitoring is when Southern Water replaced unclear, frequently paused Hi-Hi pump station alarms with StormHarvester’s AI-driven system, delivering real-time insights that prioritise and prevent critical issues from being missed.
The rollout began in Kent, followed by Hampshire and Sussex, with thousands of pump stations onboarded weekly.
- Sites became alert-active within 2 weeks from instructions to proceed.
- Sites with metadata amendments followed shortly afterwards.
- We held daily touchpoint meetings before moving to weekly check-ins.
The results showed that Pump Station Alerting is a valuable investment, Southern Water gained confidence in the system and began using the pump station visualisation tools for real-time situational awareness across the network. The alert hit rate increased to 88% following the resolution of data issues and adjustment of thresholds.
Pump station failures rarely happen suddenly, they develop over time with clear warning signs. StormHarvester’s Pump Station Alerting provides the visibility needed to identify anomalies early, enabling faster action and more reliable network performance.
