  • Maximum water level in the sedimentation tank
  • The water level control starts the submergible
    pump
  • below the maximum water level.
  • The water level control stops the submergible
    pump above the maximum water level.
  • Minimum water level in the sedimentation tank
  • The water level control stops the centrifugal
    pump
  • and starts the submergible pump below the
  • minimum water level.
  • The water level control starts the centrifugal
    pump
  • and stops the submergible pump above the
  • minimum water level but the maximum water
    level
  • control keeps the submergible pump working.
