WATER-POWERED DRILLING
STRAIGHTTO SUSTAINABILITY
Minimizing the enviromental impact and drill sustainably has become a key
factor in modern Urban Ground Engineering. With water-driven Hammers
and fuel-efficient Pumps, Wassara leads the way towards enviromentally
sustainable drilling operations.
High efficiency, low energy
Ground Engineering can become more
environmentally friendly and sustainable
by adopting and integrating innovative
technology, social, environmental and
economic developments that will minimize the
environmental impact of drilling operations.
The amount of energy used is an effective unit
to measure sustainable development, since
the consumption is always available to be
measured.
Since Wassara uses a pump instead of an
compressor to power the hammer, the energy
consumption is decreased by a factor 5. The
large iron ore mining company LKAB makes
annual saving of roughly 30 000 000 KWh,
which corresponds to the annual energy
production of 10 wind turbines.

The WASP gets it done
The WASP100D is an optimal pump for all
types of drilling, ranging from deep holes
to casing-advancement, anchoring, piling,
exploration, water wells, geothermal, production
blast holes, etc.
Its outstandingly mobility and low operating
noise-levels makes the WASP well suited for
drilling operations in sensitive urban areas.
Hammer and water
With only water both powering and lubricating the W70 Hammer, water-powered drilling is by default a
sustainable option compared to other drilling technology. No oil-lubricants are released down the hole and
since water is used to drive the drill cuttings out, no particles are jettisoned out of the hole through high-
pressure air.
Since the Wassara technique itself uses water, it drills through water-rich formations without problems. The
high penetration rate also provides very efficient and fast drilling through almost any material, from boulders
and wood to dense clay and old foundations.
In the city-center of Stockholm, the WASP100D is set-up for geothermal drilling underneath an apartment complex.
Together with the Wassara Hammer W70, this set-up enables a drilling operation with low noise and low enviromental impact.
The water-powered hammer is capable of penetrating almost any formation while maintaining speed and accuracy.
