Replacing outdated septic tanks with advanced package treatment plants offers both environmental and practical advantages:

  • Reduced Nutrient Pollution: Our advanced system upgrades reduce harmful nitrogen and phosphate discharges to safer levels.
  • Improved Water Quality and protecting public health: Upgraded systems protect sensitive ecosystems and biodiversity.
  • Sustainable Wastewater Management: Scheduled maintenance ensures ongoing compliance and performance in perpetuity.
  • Alignment with Environmental Goals: Supports local and regional efforts to protect nutrient-sensitive habitats.
  • Solutions for Small and Upstream Catchments: Septic tank upgrades can be implemented in areas where land-based schemes, such as wetlands, are not viable. This makes them ideal for smaller catchments or upstream of larger wastewater treatment works.
  • Flexibility for Developers: These upgrades provide a practical option for meeting nutrient neutrality requirements in locations where other mitigation strategies are unavailable.
