Discover essential annual maintenance steps for your septic system in New Zealand. Learn how Sustainable State's eco-friendly products can help keep your system running smoothly and compliant with local council guidelines.
Introduction
Proper maintenance of your septic system is crucial for its longevity, efficiency, and compliance with local regulations. In New Zealand, councils like Auckland Council recommend specific inspection and maintenance schedules to ensure optimal performance and environmental safety. At Sustainable State, we offer eco-friendly solutions to support your septic system's health year-round.
Annual Septic System Maintenance Steps
1. Regular Inspections
Primary Systems: Inspect every three years.
Secondary/Tertiary Systems: Inspect every six months.
Regular inspections help identify issues early, preventing costly repairs and environmental hazards.
2. Scheduled Pump-Outs
Pump out your septic tank when sludge and scum levels reach 50% of the tank's capacity. Typically, this occurs every three to five years, but frequency may vary based on usage and tank size.
3. Filter Maintenance
Clean outlet filters every one to six months, depending on usage and manufacturer recommendations.

4. Drain Field Care
Avoid heavy vehicle traffic and planting deep-rooted trees near the drain field. Ensure the area remains free from obstructions to maintain effective wastewater dispersal.
