Public Wastewater Infrastructure
C&B Drainage delivers public wastewater infrastructure for subdivision and land development projects across Auckland. Our work includes wastewater pipelines, sewer connections, manholes and associated infrastructure, delivered to project requirements and relevant Watercare standards.

Wastewater Infrastructure Built for the Site
Public wastewater projects can involve changing ground conditions, existing services, restricted access and complex connection requirements.
C&B Drainage works carefully around these site conditions to install reliable wastewater infrastructure, including pipelines, manholes and sewer connections.
Our team focuses on practical site delivery, accurate installation and completing the works to the required project standard, with attention to Watercare requirements and project specifications.
