Civil Drainage — Infrastructure That Works

Collins & Sons installs all sub-surface drainage, water, wastewater, and stormwater infrastructure across residential, commercial, and rural sites throughout the Waikato. From overland flow paths to culverts, to water/wastewater infrastructure, to retention ponds and wetlands, we handle the full scope.

We can also assist in the maintenance of your existing drainage assets, including sediment removal to maintain wetland filtration performance. Our crew works closely with engineers and project managers to ensure every system is installed to specification — on time and without the headaches.

Whether it's a complex multi-stage subdivision drainage network or a straightforward rural drain, we bring the same level of care and precision to every project. No shortcuts, no surprises.
