Wastewater Lift Stations: Dual-Pump Alternation, Lead/Lag Sequencing & High-Well Logic

Field-proven control logic for municipal sewage lift stations: lead/lag/standby pump staging, run-time equalization alternation, ultrasonic vs hydrostatic sensing, and redundant mechanical float backups.

  • Lift station wet wells must employ continuous analog level sensing paired with independent hardwired high/low floats.
  • Lead/Lag pump sequencing activates secondary pumps automatically during severe rainfall storm surges.
  • Alternating lead pumps equalizes mechanical wear on bearings and impellers, preventing concurrent dual-pump failures.
