Commercial pump stations guide

Sewage pump station design

Coordinate wet-well storage, solids-capable pumps and controls for commercial sewer lift duty.

In short

Sewage pump station design matches inflow, storage, solids characteristics and rising-main head to a packaged wet well, pumps and control panel. Commercial sewage packages sit beside the existing Pump Stations chamber catalogue. GRAF | PRESS, REUSE and CARE, plus commercial pump station packages, are being rolled out Australia-wide excluding Victoria. Project delivery, commissioning and field attendance are confirmed against location and scope.

How it works

Wastewater enters the wet well, sewage pumps and controls lift against the rising-main duty, then discharge to sewer.

What to do next

  1. 01

    Capture hydraulic and solids data

    Peak inflow, static head, rising-main details and solids characteristics.

  2. 02

    Select chamber and pump path

    Choose a catalogue wet well where suitable, then request a commercial sewage pumping package.

  3. 03

    Confirm controls and commissioning

    Level control, alarms, starts and the commissioning pathway with GRAF | CARE where required.

Commercial sewer lift applications

Apartments, mixed-use buildings, hospitality, schools, remote facilities and commercial campuses often need pumped discharge into a rising main or sewer connection.

Where trade waste or treated effluent is involved, use the matching commercial pump station package path rather than forcing a sewage selection.

Chamber selection stays tied to verified Pump Stations catalogue data.

What to bring to sizing

Project location, design flow, static head, rising-main length and diameter, pipe material, valves and fittings, wastewater type, solids characteristics, required storage, available power, control and BMS requirements, site access, loading and groundwater information, drawings and specification.

Duty/standby arrangements are common on commercial sewage stations where continuity of service matters. See the duty standby guide for redundancy planning.

Frequently asked questions

What is a sewage pump station?+
A sewage pump station lifts wastewater into a rising main or sewer when gravity drainage is not available. Commercial packages typically include a wet well, sewage pumps, valves, level controls and a control panel.
Which sites need a commercial sewage pump station?+
Commercial buildings, apartments, hospitality venues, schools, remote facilities and other sewer lift applications where the site cannot drain by gravity.
How do sewage pump stations differ from stormwater?+
Sewage packages are selected around solids handling, starts, odour and sewer authority expectations. Stormwater packages focus on drainage inflow and emergency storage for clean or lightly contaminated runoff.
Can GRAF review an existing sewage pump schedule?+
Yes. Upload drawings, duty point and specification through the quote pathway on grafaustralia.com.au.
Are commercial sewage pump stations available in Victoria?+
Commercial Systems rollout is Australia-wide excluding Victoria. Project delivery and field attendance are confirmed against location and scope.
