The cost of unplanned downtime in water and wastewater utilities
Unplanned downtime in water and wastewater utilities is among the most expensive losses in the plant because a single failure, such as pump and motor failures across distributed sites, can stop the flow, not just one asset. The true cost pairs lost contribution margin with emergency labour and expedited parts, and is usually several multiples of the repair itself.
What drives downtime cost in water and wastewater utilities
- Pump and motor failures across distributed sites.
- Blower and aeration failures affecting treatment performance.
- Deferred work building an invisible backlog across the network.
- Reactive callouts that drive overtime and travel.
