Pump Station Rising Mains support is handled around the actual pump station arrangement: chamber type, pumped material, pump duty, controls, alarms, valves, rising main, access, ground conditions and whether the work is repair, servicing, refurbishment, replacement or new installation.
The rising main is critical to pump station performance
The pumps can only perform properly if the rising main is correctly sized, routed and maintained. A poor rising main can increase head, cause repeated pump failures, create air locks, put strain on valves and reduce the reliability of the whole system.
Common rising main issues
Problems include blocked discharge pipework, failed non-return valves, damaged pipework, poor route falls, air locking, undersized pipework, incorrect fittings and difficult isolation. Symptoms can include the pump running but the chamber not emptying, repeated high level alarms, backflow into the chamber or pumps tripping under load.
- Rising main blockage checks
- Non-return valve and isolation valve issues
- Pipe route and head assessment
- Air lock investigation
- Replacement rising main advice
- Connection and discharge point review
Design and replacement support
For new pump stations, the rising main should be considered with the pump duty and chamber design from the start. For existing systems, replacement may be needed where the route is damaged, badly sized, blocked, leaking or unreliable.
