Wassara System | Water-Powered DTH Drilling System
The Wassara system is a water-powered DTH drilling system in which high-pressure water drives the down-the-hole hammer while simultaneously flushing the drill cuttings out of the borehole. Unlike compressed-air DTH systems, no compressed air is introduced into the formation.
The system is used, among other applications, for drilling where low borehole deviation, dust-free operation and minimal pressurization of the surrounding formation are important.
The Wassara system offers:
- DTH hammer powered by high-pressure water
- Water used as both the power and flushing medium
- Dust-free drilling
- Suitable for sensitive and water-bearing formations
- Various sizes from 2" to 12"
