A surveyor used a Trimble DiNi digital level to monitor reservoirs for a utility company over 4 months. The DiNi performed well in challenging winter conditions and low light. Data was easily downloaded and processed to produce required reports. The surveyor found the DiNi intuitive and fast, allowing the job to be completed accurately and on time.

1. surveyor Marian Miraute reports that the
Trimble DiNi digital level was the perfect
choice for these sites where fast and
accurate height determination is required,
often in challenging weather conditions.
“The DiNi allowed us to keep on track even
in the type of wintry conditions that have
caused issues
with other digital
levels that we’ve
used in this area,”
explains Marian.
“It also performed
well in low light
which enabled us
to remain
productive until
the sun went
down! Back at the office, collected data
was easily downloaded and processed in
Trimble Business Center to produce the
graph deliverable specified by United
Utilities. All in all, the DiNi couldn’t have
been easier to use and thanks to the
intuitive menu and fast operating speed we
were able to deliver an accurate job, on
time, and on budget.”
“All in all, the
DiNi couldn’t
have been
easier to use...”

Reservoir Monitoring
with the Trimble DiNi
A Trimble digital DiNi level may not offer Atlantic Geomatics
the cutting edge technology of their recently acquired R10
GNSS, but when it comes to getting the job done, the
Trimble DiNi has proved to be the perfect choice for the
company’s recent 4 month damn monitoring project.
Atlantic Geomatics, a multidisciplinary
surveying and GIS practice based in
Penrith, was recently awarded the contract
to carry out an annual damn monitoring
survey on behalf of United Utilities, a
company which owns 182 reservoirs that
are managed in accordance with the
Reservoirs Act 1975 and is responsible for
the provision and maintenance of water
supply in the North West of England.
In order to comply with the Act, 147 of their
reservoirs are monitored at least annually
to ascertain any change in the movement/
settlement of the embankment/concrete
dams with a view to providing a means of
early detection of asset deterioration so
that appropriate proactive management
can be undertaken to ensure the continued
safe operation of the reservoirs.
The project being undertaken by Atlantic
Geomatics started in October and work is
being carried out almost exclusively with a
KOREC supplied Trimble DiNi level, an
instrument which allows users to
determine height information 60% faster
than with automatic levelling and can
measure to a field of just 30cm.
At each of the sites, permanent ground
control had already been established with
a Trimble GNSS. The DiNi was used to
level from this off-site control. Some
reservoirs required 60 – 70 points to be
monitored over a distance of several
kilometres whilst others required just 7 or 8
readings depending on the number of
pins. With the dual demands of a tight
schedule and having to work in very
exposed areas, Atlantic Geomatics
