Approximately 20% of Australian residential properties face challenges with gravity-based wastewater disposal, making sewer pump stations essential for efficient drainage management. When your house sits on low-lying land or has plumbing fixtures below the level of the main sewer system, gravity alone simply won’t cut it.
Sewer pump stations provide a practical solution by pumping wastewater uphill, effectively overcoming elevation barriers and ensuring proper sewage removal. Installing the right type of pump station, a domestic package system tailored to your property’s size and wastewater needs, is critical.
Correct installation ensures compliance with local environmental protection regulations and guarantees safe, reliable, and trouble-free operation over the long term.
Site Assessment and Planning for Your Sewage Pump Station
Proper site assessment and planning are essential for installing an effective sewer pump station tailored specifically to your property. Careful evaluation at this stage sets the stage for successful wastewater management.
Evaluating Site Conditions
To determine if your house requires a sewer pump station, you must first assess site elevation, slope and plumbing fixture locations. Identifying the lowest wastewater collection point at your property helps establish the necessity of installing a pump station to transport sewage or stormwater uphill towards the main sewer.
Depending on the application, this assessment may vary in complexity and depth. Consider environmental protection factors, including proximity to natural watercourses and potential contamination risks.
Additionally, stormwater considerations are critical, as incorrect placement may lead to drainage issues or flooding.
Selecting the Right Sewer Pump Stations Type
Several types of pump stations exist, each suitable for different domestic situations:
- Submersible pump stations: Ideal for residential applications, capable of handling solids and liquid waste effectively.
- Dry well stations: Suitable when regular maintenance access is required, although less common in standard domestic scenarios.
- Grinder pump stations: Recommended for properties generating significant solid waste, reducing blockage risks.
- Packaged pump stations: Offer convenience and ease of installation, combining pump, tank and controls in a single unit, reflecting technical best practice guidelines.
Consider anticipated wastewater flow, household size, and solid waste handling requirements when choosing the appropriate system.
Regulations and Approvals
The installation must fully comply with Australian Standards, particularly AS/NZS 1546.1:2008, which covers on-site wastewater systems. Before commencing work, consult local water authority regulations early to understand specific approval procedures and required permits.
Choosing the Correct Equipment for Your Sewage System
Selecting suitable equipment is critical for an efficient and environmentally responsible sewerage system. Careful decisions regarding pumps, tanks and component parts will ensure reliable transport and management of sewage at a higher level.
1. Determining Suitable Pump Capacity
Accurate pump selection begins with estimating daily wastewater volume and peak flow rates for your household. Consider the number of occupants, average water consumption and waste generation patterns. Typical domestic wastewater production ranges from 150 to 250 litres per person each day.
Allow additional capacity for peak usage events and future household expansion. Ensure your selected pump comfortably handles fluid volumes without risk of overflow or operational strain.
2. Selecting Tank Material and Size
Australian domestic sewage pump stations commonly feature robust tanks crafted from fibreglass, polyethylene, or high-density polyethylene. These materials deliver exceptional durability and corrosion resistance.
Common tank sizes include:
• 500 litres: This compact size is ideal for smaller domestic settings, greywater, or stormwater applications. It offers adjustable inlet and outlet positions.
• 700 litres: Suitable for limited-space residential installations, typically vertical underground tanks with smaller footprints.
• 1000 litres: Most popular standard domestic tank size, balancing wastewater capacity with manageable dimensions. Offers flexible inlet heights and optional alarm systems.
• 1300 litres: Ideal for larger households anticipating growth, providing increased storage capacity and efficient wastewater handling.
• 3000 to 4500 litres: Primarily septic tanks, these larger options suit combined septic and pump station use for sizeable homes requiring additional wastewater management.
Always choose tanks certified to the Australian Standard AS/NZS 1546.1, which ensures compliance with council regulations and reliable long-term performance.
3. Essential Components of a Sewer Pump Station
A fully functional station typically includes:
- Wet well (pump chamber)
- Submersible pumps (dual setup for duty and standby operation)
- Guide rails and lifting chains (Grade 316 stainless steel recommended)
- Non return and isolation valves
- Control and alarm panel
- Venting provisions ensuring proper environmental protection
Pre-assembled packages are council approved solutions offering convenience and ease of installation.
Installation Steps for Domestic Sewer Pump Stations
Proper installation of domestic sewer pump stations ensures reliable performance and prevents costly issues. Follow these detailed steps to achieve a safe and compliant setup.
1. Site Preparation and Excavation
Start excavation carefully and consider crucial clearances from boundary lines, buildings and windows. Safety and accessibility are essential, so maintain at least two metres from property boundaries and about three metres clear from windows. The operator must ensure excavation dimensions specify sufficient space to accommodate the station securely.
- Excavate area, maintaining recommended clearances
- Prepare a compact, stable and level base
- Confirm underground stability to avoid future tank shifting or failure
2. Tank and Pump Installation
Tanks are available in a range of sizes, suitable for domestic wastewater needs. Carefully lower the tank into excavation, anchoring securely in high water table areas to withstand rainfall fluctuations. Ensure inlet pipework is properly installed and sealed.
