A Practical Approach to Underground Infrastructure
WICS Hydro
WICS Water is a Christchurch-based civil contractor specialising in hydro excavation and water infrastructure works across Canterbury.
Our business was built from hands-on installation experience — working directly with water, sewer and drainage systems — before expanding into hydro excavation.
Because of this, we don’t just expose underground services — we understand how they are constructed, how they connect, and how to work around them safely.
Today, our hydro excavation capability supports a wide range of projects, from residential connections to commercial infrastructure, while our certified installation work ensures everything we uncover can also be properly built, repaired or upgraded.

Why Experience Matters
Working underground carries risk.
Damaging a live service can stop a project, disrupt supply and create serious safety hazards.
Our approach is simple:
Expose safely
Understand the asset
Install correctly
By combining non-destructive excavation with installation knowledge, we reduce uncertainty on site and help projects progress without unnecessary delays.
