Pump Station

Yes. Sewer pump stations and stormwater pump stations require regular maintenance to prevent blockages, keep pumps operating efficiently, and extend equipment lifespan. Typical servicing includes checking float switches, removing solids buildup, testing the alarm, and inspecting internal valves and fittings. Our sewage pump stations are designed to handle both black water and stormwater with minimal maintenance, ensuring long-term reliability and compliance for every installation.

The lifespan of a sewage pump station chamber can last for decades due to its corrosion-resistant construction, while the pump itself typically lasts 7–10+ years, depending on load, wastewater type, and maintenance frequency. With regular servicing and correct installation, both the pump and chamber lifespans can be extended.

Polymaster pump stations are made from tough, rotationally moulded polyethylene that is corrosion-resistant, chemical-resistant, and compliant with AS/NZS 1546.1. This material choice gives the chambers strength, durability, and long-term resistance to harsh wastewater environments. Internal components include brass fittings, PVC unions, swing check valves, and high-grade pumps, depending on the configuration.

If a pump station fails, wastewater can’t be discharged. In sewer pump stations, failure can lead to wastewater backing up. In stormwater pump stations, it may cause pooling or localised flooding. Prolonged stagnation can also cause odours or environmental risks.

A correctly installed and maintained pump station should not smell. Odours usually indicate a blockage, poor ventilation, or stagnant wastewater. When pumps operate correctly and the chamber is sealed and vented properly, odours remain contained.

A pump station must be installed on a stable, level base with compliant inlet and discharge pipework, safe access for maintenance, proper ventilation, and licensed electrical connection for the pump and alarm system. Polymaster stations simplify installation because the chambers are lightweight, self-anchoring (no concrete required), and pre-assembled with valves, fittings, a brass discharge outlet, and a high-level alarm. Qualified installers only need to connect plumbing and power, set inlet heights, and ensure local regulations are met.

For commercial and industrial sites, pump station size depends on inflow volume, peak demand, solids handling requirements, and the distance and height the wastewater must be pumped. Factors such as trade waste load, process water discharge, the number of connected fixtures, and emergency storage requirements also influence chamber size. Polymaster provides three capacities - 700L, 1000L, and 1300L - each with multiple inlet positions and pre-plumbed internals, making it easier to match the correct size to varying commercial loads. Most projects determine the right size through hydraulic calculations or by consulting a pump station designer.

Sewer pump stations and grey water pump stations are designed to move wastewater, sewage, or greywater from low-lying areas to the main sewer or treatment system when gravity fall isn’t available. It prevents backups, allows flexible site design, and ensures wastewater is safely transferred without manual intervention.

A sewage pump station works by collecting wastewater in a chamber and automatically pumping it to a higher point when gravity can’t move it on its own. Once the liquid level rises to a set point, the pump activates and pushes the wastewater through a pressurised discharge line until gravity flow can resume.
