Technical Solutions · GRAF | LIFT
Commercial pump stations for stormwater, sewage, effluent and trade waste
GRAF | LIFT combines the wet well, pumps, pipework, valves, level controls, electrical controls and commissioning pathway into one coordinated commercial pumping solution.
Pump-out wet wells - stormwater and wastewater transfer
GRAF Carat pump-out wet well
Process
Pump station system
Underground collection flows into a GRAF Carat or Sapphire pump-out wet well, where submersible pumps transfer water to the discharge header.
- 1Stormwater or wastewater flows to underground collection point
- 2GRAF Carat / Sapphire pump-out tank - pre-fabricated wet well with access cover
- 3Submersible pump, riser pipework and level controls
- 4Discharge to sewer main, irrigation or downstream treatment
GRAF | LIFT, PRESS, REUSE and CARE are being rolled out Australia-wide excluding Victoria. Project delivery, commissioning and field attendance are confirmed against location and scope.
How the system works
From inflow to discharge
1. Collect
Wastewater or stormwater enters the selected wet well.
2. Store
Usable and emergency storage is established around the project inflow.
3. Pump
Pump type and quantity are selected from the hydraulic duty and fluid.
4. Control
Floats, level instrumentation and controls manage operation and alarms.
5. Discharge
Pipework and valves deliver flow into the rising main or receiving system.
6. Maintain
Commissioning and lifecycle support are considered from the start.

What we need to size the station
- Project location
- Design flow or inflow
- Static head
- Rising-main length and diameter
- Pipe material, valves and fittings
- Wastewater or stormwater type
- Solids characteristics
- Required storage
- Available power
- Control and BMS requirements
- Site access, loading and groundwater information
- Drawings and specification
FAQ
- Does GRAF supply more than the tank?
- Yes. The existing Pump Stations catalogue remains the chamber and wet-well product range. GRAF | LIFT is the pathway for a coordinated commercial package including pumping, controls and associated equipment.
- Is GRAF | LIFT available nationally?
- The active rollout is Australia-wide excluding Victoria. Delivery, commissioning and field attendance are confirmed against the project location and scope.
- Can GRAF review an existing pump schedule?
- Yes. Upload the drawings, duty point and specification through the quote pathway on grafaustralia.com.au.
