Sewage Pump System Upgrades

Our Specialized Service inspection / WOF assessment can point out any underlying issues with the system.

This includes some of the below inspections.

• Identify Issues: Determine the reasons for the upgrade, such as frequent pump failures, insufficient capacity, chamber overflow or excessive noise.
• Evaluate Performance: Assess the current pump’s performance, including flow rate, head pressure, and power consumption.
• Inspect Components: Check the condition of other system components, such as pipes, valves, and controls, to identify any needed repairs or replacements.
• Electrical compliance: Test electrical components and cabling according to New Zealand electrical regulations.

• Flow Rate and Head: Calculate the required flow rate (GPM or L/s) and total dynamic head (TDH) needed to effectively move sewage to the main sewer line.
• Future Capacity: Consider any potential future needs, such as increased usage due to renovations or expansions.

• Pump Type: We select the appropriate pump type based on the application, such as:
  • Submersible Pumps: Ideal for installations below ground; they operate underwater and are typically quieter.
  • Effluent Pumps: Suitable for pumping treated wastewater or sewage with smaller solids.
  • Grinder Pumps: Designed to handle sewage with larger solids by grinding them before pumping.
• Power Requirements: Ensure the new pump meets the power needs for the system while being energy efficient.

• Control Systems: Consider upgrading to a more advanced control system that allows for automated monitoring and management of the pump, including alarms for failures.
• Float Switches and Sensors: Install reliable float switches or level sensors for precise control of pump operation.
• Piping and Valves: Evaluate the existing piping for wear or blockages and replace or upgrade as necessary to ensure smooth flow.
• Check Valves: Install or upgrade check valves to prevent backflow and protect the pump.

• Plan for Downtime: Schedule the upgrade to minimize disruption, especially in commercial settings.
• Professional Assistance: Engage a licensed plumber experienced in sewage pump discharge to ensure proper installation and compliance with local codes. If upgrades to underground pipework is required.
• Testing: After installation, conduct thorough testing to ensure the system operates as intended and meets all specifications and legal requirements.

• Regular Maintenance: Establish a maintenance schedule to inspect the pump and related components, checking for wear and tear, clogs, and operational efficiency.
• Monitoring Systems: Consider installing monitoring systems that alert you to issues like pump failure, high water levels, or system overload.

• Keep Records: Maintain documentation of the upgrade, including permits, inspection reports, and warranties.
• Code Compliance: Ensure all upgrades comply with New Zealand electrical regulations.

• Increased Efficiency: Modern pumps often have better energy efficiency, leading to reduced operational costs.
• Enhanced Reliability: Upgraded systems are less prone to failures, leading to fewer emergency situations and maintenance calls.
• Improved Capacity: Addressing current and future needs can prevent overflow or backups, improving overall system performance.

Upgrading a sewage pump system is essential for maintaining reliable wastewater management, ensuring compliance with regulations, and improving overall efficiency and performance. Proper planning, assessment, and execution can lead to long-term benefits and peace of mind.
