Lift Stations · Alarms, SCADA, and Callout Response
What Does a Lift Station High-Level Alarm Mean?
A high-level alarm means the wet well has risen above its normal operating range. Available storage may be decreasing, so the response must be prompt and organized.
First review the information available without delaying dispatch. Determine pump status, power condition, recent alarms, incoming weather, known outages, and whether staff are already responding.
At the site, follow plant procedures to protect workers and the public. Confirm actual level from an authorized location, assess whether pumps are moving flow, and prepare approved backup measures when needed. Know roughly how long the wet well and upstream sewers can hold flow after a high-level alarm before an overflow could occur. That time depends on the station and the inflow, and it tells you how fast the response must be.
Do not reset the alarm and leave without finding why it occurred. Document the maximum known level, equipment condition, response actions, and whether an overflow or backup happened.
Key point: A high-level alarm warns that storage is being consumed and the cause must be confirmed quickly.
