DrainAce Pressure Sewer Systems provide a practical alternative to conventional gravity sewer networks where deep trenching, difficult terrain, groundwater or high installation costs make traditional sewer infrastructure challenging.
Using a compact grinder pump station at each property, wastewater is transferred through a small-diameter HDPE pressure pipe network, reducing excavation requirements and allowing pipelines to follow the natural contours of the land.
The result is a reliable, cost-effective sewer solution that can lower civil construction costs, minimise site disruption and simplify network expansion.
The DrainAce pressure sewer system provides an efficient wastewater solution for residential, commercial, and municipal developments.
Each system consists of a grinder pump, polyethylene chamber, advanced control panel and alarm system, providing a reliable method of transferring wastewater through a pressure sewer network.
Available with multiple chamber sizes, pump materials and cover options, the system can be configured to suit a wide range of site conditions and project requirements.
DrainAce systems are supplied as complete solutions, ready for integration into new developments, network extensions and pressure sewer infrastructure projects.
Two pump variants are available, both delivering identical hydraulic performance.

1. Wastewater collection
Wastewater from a home, commercial building, or facility flows into an underground collection tank or wet well.
2. Storage and level detection
The tank temporarily stores the wastewater.
As the liquid level rises, float switches or level sensors monitor the volume.
3. Pump activation
When a preset level is reached, a grinder pump or solids-handling pump automatically starts.
The pump pressurises the wastewater and forces it into a small-diameter pressure pipeline.
4. Pressurised transport
Unlike conventional gravity sewers, the wastewater is pumped through the network under pressure.
This allows it to travel over long distances, uphill, around obstacles, or across challenging terrain.
5. Discharge to the sewer network or treatment plant
The wastewater is delivered to a gravity sewer, pump station, or directly to a wastewater treatment facility.
Once the tank level drops to a predetermined point, the pump switches off.
Key advantage
Because the system uses pressure rather than gravity, it can be installed in locations where conventional gravity sewers would require deep excavations, extensive trenching, or multiple lift stations.
Global Water’s DrainAce Pressure Sewer Pump Stations are designed for versatility, making them ideal for a wide range of wastewater applications, particularly where challenging site conditions make conventional sewer infrastructure difficult or costly to install.
They are well suited to sites with:
