Stormwater & Sewage Pump Stations

When you are managing a large-scale industrial facility, a transport depot, or a commercial site, managing water effectively is just as important as managing your daily operations. Moving clean water is relatively straightforward. However, when you need to move heavy sludge, trade waste, raw sewage, or massive volumes of unpredictable rainwater from a low point to a higher elevation or a municipal connection, you are fighting a battle against gravity and solids.

This is exactly where Stormwater & Sewage Pump Stations come into play. They are the unseen heavy lifters of your site’s infrastructure.

Unfortunately, we see it all the time in the wastewater management industry: businesses try to save money by installing cheap, off-the-shelf pump pits. A few months later, the pumps choke on debris, burn out, and raw sewage or contaminated stormwater floods the site. The resulting environmental fines and emergency liquid waste disposal fees drastically outweigh the initial “savings.”

At GPS Environmental, we don’t just sell standard plastic pits. We engineer and supply highly durable, site-specific Stormwater & Sewage Pump Stations designed for zero downtime and absolute compliance. Here is everything you need to know about how they work, why cheap systems fail, and how to choose the right equipment for your operations.

Stormwater & Sewage Pump Stations are engineered collection and transfer systems designed to transport wastewater, raw sewage, or rainwater runoff from a lower elevation to a higher elevation, or directly into a municipal sewer main, when gravity alone is insufficient to move the liquid.

While they are often grouped together, the two systems handle vastly different types of liquids and require completely different engineering approaches:

Stormwater Pump Stations

During heavy rainfall, massive volumes of water hit your facility’s roof and hardstand areas. If this water pools in low-lying areas, it can flood your operational zones or wash bay bunds, causing a massive environmental hazard. A stormwater pump station captures this rapid influx of water in a collection chamber. Because stormwater can arrive in massive, unpredictable surges, these stations rely on high-volume, high-flow pumps designed to evacuate water quickly.

Sewage and Trade Waste Pump Stations

Unlike stormwater, sewage and industrial trade waste do not arrive in sudden, massive surges. Instead, they provide a steady, consistent flow of liquid that is heavily laden with solids, rags, grease, and biological matter. A sewage pump station requires specialized heavy-duty pumps—often fitted with vortex impellers or macerating cutter blades—that can chew through solids without clogging the suction lines or jamming the motor.

We supply both stormwater pump stations and sewage pump stations across Australia, engineered to integrate seamlessly into new and existing infrastructure.

A sewage pump station is designed to manage domestic or commercial wastewater and transfer it to:

• Reticulated sewer networks
• On-site sewage treatment systems
• Wastewater treatment plants

Available in single or dual pump configurations, our packaged sewage pump stations provide redundancy and reliability where continuous operation is essential.

Dual pump systems are particularly suitable for:

• Multi-residential developments
• Commercial buildings
• Industrial facilities
• High-demand applications

Stormwater pump stations are critical in managing flood risk and surface water runoff where gravity drainage is insufficient.

Our stormwater pump stations are engineered to:

• Handle peak rainfall events
• Manage high inflow volumes
• Protect infrastructure from flooding
• Operate automatically with level controls

Designed for durability and efficiency, these systems help safeguard properties, roadways and industrial sites across Australia.

At GPS Environmental, we build wastewater systems designed to protect your bottom line by eliminating breakdowns and emergency maintenance. When you purchase our Stormwater & Sewage Pump Stations, you are investing in industrial-grade reliability.

Here is what sets our engineered solutions apart from the competition:

We rarely design a commercial station with just one pump. Our Stormwater & Sewage Pump Stations utilize a “Duty/Standby” configuration. This means two identical pumps sit at the bottom of the chamber. A smart controller alternates the workload between them to ensure even wear. If the primary “duty” pump fails or gets blocked, the “standby” pump automatically kicks in, triggering an alarm to notify you while completely preventing an overflow.

We supply heavy-duty cast-iron pumps featuring advanced vortex impellers and grinder blades. Instead of jamming when industrial waste, rags, or heavy mud enters the chamber, our sewage pumps effectively chew through the solids, macerating them into a fine slurry that easily passes through the discharge pipework.

Maintaining an underground pump should never require a confined space entry permit. Our Stormwater & Sewage Pump Stations are fitted with heavy-duty stainless steel guide rails. If a pump needs servicing, it can simply be hauled up to the surface via a lifting chain. When the service is complete, the pump slides perfectly back down the rail and locks into the discharge flange automatically.

A pump station should never fail silently. Our systems are wired to advanced, weather-proof control panels equipped with high-level alarms, audible sirens, and flashing strobe lights. For remote or highly critical sites, we can integrate telemetry systems that instantly send an SMS alert to your facility manager the second a high-water level is detected or a pump trips.

As experts in industrial wash bays, we know that a pump station is only as good as the water entering it. We actively design our pump stations to work in seamless harmony with your heavy-duty silt traps, drive-in beach pits, and oil-water separators, ensuring that large rocks, heavy mud, and free-floating oils are removed before they ever reach your pumps.
