Septic Tank & Soakage Field Sizing Tool
Get a clearer starting point for on-site wastewater planning with a tool designed to support early septic tank and soakage field sizing.
Estimate likely system requirements
This tool provides a simplified and conservative estimate to help users work through likely septic tank and soakage field requirements based on site conditions and wastewater demand. It is intended to support early planning and help establish a more informed direction.
Use it as preliminary guidance
Because wastewater requirements can vary by council, designer, and site-specific conditions, the tool is best used as preliminary guidance rather than final design. It gives homeowners, plumbers, and specifiers a practical starting point before moving to site-specific assessment or detailed wastewater design.
