Wastewater Design

We provide end-to-end wastewater design services for residential and light-commercial projects across the Tasman and Nelson regions. Our designs are tailored to real site conditions — including soil types, land contours, and loading requirements — to ensure systems that perform reliably long after installation.

Whether you’re building new, upgrading an existing system, or addressing a failing wastewater setup, we take the guesswork out of the process. From site assessment and system sizing through to layout plans and consent-ready documentation, we deliver practical, compliant designs that are built to last.

We work closely with councils, inspectors, and installers to help streamline approvals and ensure each system meets local authority requirements while remaining cost-effective and easy to maintain.
