Company Profile
Our engineering establishment in Mals - Vinschgau / South Tyrol - Italy was founded by Ronald
Patscheider in 1995. We initially focused our planning mainly in the structural engineering sector. Since
our field of activities has expanded in recent years, our office is presently in charge of larger projects
covering almost all areas of engineering.
Consequently, we increased the number of our employees and reorganized the association at the
beginning of the year 2000 in order to meet the needs of the broader activities and the rising number of
projects we were being confronted with. Since February 2000 we have been known as "Patscheider &
Partner". In order to further increase our efficiency, in October 2005 our company has got the juridical
form of a society with limited responsibility.
At the moment our companies gives employs around 40 highly qualified collaborators, running offices in
Mals/Italy and Bolzano/Italy.
Even when dealing with complex projects we are responsible for all stages of planning and construction.
In keeping regular contact with our clients, government bodies and public interest groups we are able to
tackle even the most complex of projects as efficiently as possible. We therefore ensure that integral and
future-oriented proposals are developed and subsequently realized in sustainable projects.
Further basic principles of our company are high reliability and strict observance of contract agreements
and appointments.
Through steady contact with universities and continuous training of our employees we keep up with the
latest knowledge of engineering. By using the latest hardware and software programs available on the
market, we guarantee the highest level of technical standards.
By working closely together with other technical offices we can expand our activities within the shortest
time. Thus we mobilize important capacities and work out the best solutions by interacting with
interdisciplinary teams.
To ensure continuous improvements of quality in our work we have introduced the Quality Management
System ISO 9001, which we completed and received in April 2001. In 2004, 2007 and 2010 our Quality
Management System was reconfirmed.

during summer time and produce milk products such as cheese,
yoghurt and milk. For their activity they need drinking water of
high quality.
They are on a high altitude (2.000 m above sea level).
On individuated springs chemical and biological quality of water
was tested.
Projects were carried out with special respect to the
environment in order to minimize the impact on it.
Springs were captured with the help of small excavators.
Downstream of the springs prefabricated tanks were the water
is cleaned and stocked were installed.
Conduits were realized in order to supply the alps.
The plants need very few maintenance and are highly suitable
to satisfy the needs of the alps.

Sectors Hydropower
Cost of construction 2.900.000.- Euro
Key features of projectsj A run of river plant with an installed capacity of 2 MW and a
design discharge of 8 m³/s were built.
Our office carried out the design of the water intake and the
sand trap, optimizing the layout of the preliminary project.
The water intake is a lateral intake where the water level is
controlled by a regulated flap gate. The sand trap is designed
as a double settling chamber.

Key features of projects In the borough of Stilfs and its surrounding villages (1’500
inhabitants), the water supply network was in degraded
conditions. Furthermore, the village lies on a very steep
mountain slope, the streets of the borough are very narrow, and
transport vehicles cannot pass.
A master plan was carried out in order to define a 5 years
program with different priorities for the complete renovation of
the water supply system.
A hydraulic model of the water supply network was carried out
in order to control the pressures in the network in both the
normal and the fire case.
The project contained the renovation of the whole infrastructure
network (water supply, sewer system, electricity, public light,
telecommunication). The main challenge was to individuate
special solutions that allowed to realize the structures despite
the critical topographic situation.
The following measures have been realized: renovation of
spring water intakes, construction of several pressure reduction
valves, replacement of different main conduits, refurbishment of
reservoir and tanks with regulation, complete reconstruction of
the water supply network.

Key features of project The city of Bolzano lies on the confluence of the river Eisack
and the torrent Talfer. A last part remained after important
protection works from 1990 to 2000.
This part has a length of 1 km and it shows some interesting
features: it is a zone with a high ecological value, it is situated
near important infrastructures such as the stadium and the
public swimming facilities and it represents the connection
between two important bicycle paths in Bolzano.
The water levels for different return periods were defined by
means of the software HEC – RAS.
In a project that considered the crucial aspects, different
measures were carried out. The river bank protection was built
by bioengineering methods, a new bicycle path was built, a bar
was integrated into the river protection wall and a new
recreation zone was realized.
The project represents an example for a sustained flood
protection. It is highly accepted by the population. The
recreation zone is always used by many people.

Key features of project The ski resort “Piani di Bobbio” didn’t have a proper snow
making plant. The main ski trail was too narrow.
In the project the main ski trail was upgraded and widened.
In three different project units an artificial snow making plant
was built. Within the frame of the project 4 km of pressure
conduits and a pumping station with 3 pumps having each an
installed capacity of 355 kW was built. Furthermore the pumping
station for the drinking water was adapted in order to supply
also the snow making plant with water.

Refurbishment of a diversion pressure conduit, risk investigation of a pressure conduit
Ordering Customer Edison Plc
Period 2002 – in execution
Services Hydraulic modeling
Tender documents
Safety planning
Sectors Hydropower
Key features of projects The power plan of Graun (installed capacity 6,3 MW) has been
in operation since 40 years.
The consequences of a failure of the main pressure conduit
were examined in a risk investigation. For that purpose a
bidimensional flood routing model (FLO-2D) was used in order
to get flow depths and velocities following a failure of the
pressure conduit.
A diversion pressure conduit conducts water from the opposite
side of the valley into the main pressure conduit. This pressure
conduit (DN 600) was in poor condition. A project for the
refurbishment of this conduit and for the reconstruction of the
crossing of the main torrent of the valley was worked out. After
an economical and technical analysis a cast iron pipe was
chosen.

Tender documents
Safety planning
Sectors Hydropower
Irrigation
Structures
Key features of projects The Public Electricity Service and the Irrigation Consortium of
Prad run a common water intake, a sand trap and a pressure
conduit.
The efficiency of the sand trap was very low as the captured
river is characterized by a very intense sediment transport.
Additionally, the sand trap had not been designed properly.
In a feasibility study different solutions were worked out in order
to individuate the best option in economical and technical terms.
The sand trap was modified into a double settling chamber. At
the outlets of the chambers automatically regulated gates were
installed, the geometry of the chambers was adapted and a new
service building was erected.
The work had to be carried out in a very short period (20 days)
under hard climatic conditions. In collaboration with the
contractor a tight working schedule was established allowing to
keep the deadlines.

Refurbishment of an irrigation plant in Allitz
Ordering Customer Irrigation Consortium Vinschgau
Period 2003 – 2007
Tender documents
Safety planning
Sectors Irrigation
Structures
Key features of project The Irrigation plant of Allitz showed several problems:
- The water intake, built as a lateral intake, captured a lot of
bed load that was settling down in the channel downstream.
It could not be removed automatically.
- The main pressure conduit crossed a torrent beneath its
bed by means of a quadratic concrete channel that was
heavily damaged.
- A connecting conduit between two basins was of bad quality
and, due to sudden ruptures, it heavily endangered the
houses situated downstream.
Therefore, a project with the following measures was carried
out:
- A new water intake, built as Tyrolean weir, was realized. A
sand trap was built behind the water intake, where flushing
is automatically possible.
- Instead of the quadratic concrete channel a cast iron
conduit (diameter 500 mm) was placed beneath the bed.
- The connecting conduit was replaced by a cast iron pipe,
too. Furthermore, an automatic closure and warning system
for the cases of failure were installed.

Ordering Customer Irrigation Consortium Vinschgau
Period 2004 – 2007
Preliminary design
Tender documents
Safety planning
Sectors Irrigation
Key features of project The irrigation plants “Göflaner Wiesen” and “Suppenwaal” had
several problems:
- The torrent, that serves the irrigation plant, has a low
discharge. There was no possibility to store water in order
to increase discharge for irrigation and hence to optimize
the operating of the plant.
- The water intake, built as a Tyrolean weir, was not working
very well: a lot of bed load was captured clogging the
conduits.
- The pumping station, situated in the center of the plant,
didn’t fulfill its functions.
Therefore, the following measures were taken:
- The water intake was rebuilt. It got a geometry which keeps
the bed load away efficiently.
- An ellipsoidal storage basin (2.000 m³) in concrete was
realized.
- In the pumping station new valves and collecting conduits
were installed to improve its function.

Period 2004 - 2006
Environmental impact study
Tender documents
Safety planning
Sectors Irrigation
Structures
Key features of project The irrigation plant of Schlanders covers an area of
approximately 380 ha.
In order to optimize the operating modes of the plant, the
diameter of the main pressure conduit had to be increased from
300 mm to 500 mm. At the same time the conduit had to be
removed from an urbanized area to a new line outside of it.
A torrent had to be crossed twice: once superficially and once
beneath the bed. Furthermore, two main roads were crossed by
a no dig system. Another challenge was to organize work in
such a way that it does not overlap with the activities of the
farmers in the orchards.
The sand trap of the plant was not working properly. In order to
improve the situation a new sand trap was built. The sand trap
has two chambers where solid load is settling down. It also has
a rotating filter where waste load is captured.

Period 2004 – 2008
Tender documents
Safety planning
Sectors Irrigation
Structures
Key features of project In the upper Vinschgau Valley mean annual precipitation is very
low (ca. 500 mm).
A surface of 500 ha is still irrigated by artificial channels wherein
the water is diverted from the rivers. A lot of maintenance work
has to be done and the farmers are no longer able to maintain
these irrigation channels in a good state.
A plant, covering the whole surface, has been be built. On this
plant, irrigation is now done by sprinklers. The project is
financed both by the State and by the Province.
The plant covers an area with a height difference of 600 m.
Therefore, pressure breaking and reducing devices had to be
built.
By using of the software EPANET, the whole system was
dimensioned in order to guarantee an ideal range of pressure at
the sprinklers (3 – 7 bar) and in order to establish optimized
working schedules for the operators of the plant.
The total lengths of the conduits is around 100 km. The
diameters vary between 600 mm and 40 mm. The used
materials are cast iron and polyethylene. The maximum static
pressure is 25 bar, the minimum dynamic pressure 3 bar.
3 pressure breaking chambers and 4 pressure reducing stations
have been built. The whole plant is equipped with a monitoring
system in order to control water consumption and to prevent
damages in case of conduit failure.

Hydropower potential study of a watershed
Client SEL Plc
Period 2005
Services Hydraulic study
Sectors Hydropower
Key features of project The Upper Rienz watershed has a surface of 415 km².
The hydropower potential of the Upper Rienz watershed is only
partially exploited.
The remaining hydropower potential was investigated in a
hydraulic study. First of all, the gross theoretical hydropower
potential was estimated. The lineal potential, the technically and
the economically utilizable potential were derived from the gross
theoretical potential.
Several possibilities for the realization of new hydro power
plants were defined. Several of the projects have been realized
subsequently.

Key features of project The SEL Plc plans a new run of river plant at the Eisack river.
The water will be diverted into a pressure gallery with a length
of around 12 km. The design discharge is 27 m³/s, the head
183 m and the installed capacity is 41 MW.
A quantitative and qualitative comparison between different
variants from the environmental point of view was carried out in
an environmental impact assessment study.
Our office examined the topics related to the impacts on the
hydraulic aspects, such as flood behaviour, bed load, influence
on ground water, consequences for leisure activities on the river
etc.
Especially the consequences on the water depth and width and
on the flow velocity in the residual water reach were studied by
means of a hydraulic modeling of low discharges. It was found
out that a decrease in discharge of 75 % only causes a
decrease of water depth, width and velocity of around 25 %.
By means of structural measures in the residual water reach the
ecological quality can be maintained and partially even
increased.

Key features of projects The ski resort of Sulden, despite of its height, in the coming
years needs an artificial snow plant.
The new artificial snow plant covers an area of 60 ha.
The artifiicial water storage basin, constructed in the year 2008,
has a volume of 32.000 m³, a water height of 8.5 m and a dam
height of 4 m. In order to protect the basin from avalanches also
a protection wall with a height of 9 m has been built.
Within 9 months it was possible to obtain all the authorizations
of the project and to carry out the realization of the project.

Key features Goal of the project was to realize two basins for the new
snowmaking systems of the ski-area “Rosa Khutor”, in Krasnaja
Poljana (Sochi, Krasnodar Region, Russia) were the Olympic
games in 2014 took place. The two basins have a volume of
70.000 and of 55.000 m³ approx. with water depths of 6 m and
will serve the plants for Olympic Winter Games “Sochi 2014”.
Basing on an existing project the solutions for the drainage and
for the waterproofing had to be optimized and brought to the
state of the art. The project involved both basins.
Annex structures are:a drainage system monitoring station, a
bottom outlet, water intakes and spillways.
The entire construction phase was followed with day-by-day
surveillance and control. The basins were completed in 2010
and 2011.
