Hydro Excavation

Wastech Services Central Otago provides hydro excavation services throughout the Central Lakes region.

Why choose Hydro Excavation?

Hydro Excavation is also known as vacuum excavation, hydro trenching and hydro digging. Essentially, hydro excavation provides a safer method than digging. A high-pressure jetting and vacuum unit work simultaneously, blasting around the services (commonly known as trenching) whilst excavating solid debris and liquid waste. This lowers the risk of any damages to the services underground and so reduces the risk to the public and to any workers in the area.
