Watertec 50 Water Well Drilling Rig

The most powerful of Dando’s range of water well rigs, the Watertec 50 is specially designed for drilling large diameter wells.

This model is often selected when wells are required to produce high volume supply, municipal water supply for example, or in areas where aquifers are located at great depths.

Utilising a combination of hydraulic rams and a powerful winch the full 50,000kgf of pullback allows the handling of long lengths of large diameter casing and drill pipe. A large diameter central passage through the rotary head lends this rig to flooded reverse circulation drilling as well as conventional mud and DTH hammer drilling.
