The force main was installed via a horizontally drilled hole to the exact elevation of the wet well connection. The submersible solids handling pumps are explosion proof to meet the hazardous area classifications for this lift station. A sheltered PLC control panel contains an intrinsically safe barrier to also meet the hazardous area requirements. The panel utilizes a pressure transducer and floats for primary and backup level-sensing controls.
