Bypass Biel

Bypass Biel – ductile cast iron extinguishing water pipes

Bypass Biel – ductile cast iron extinguishing water pipes in the Büttenberg and Längholz motorway tunnel

The A5 motorway bypass around the City of Biel on the stretch between Solothurn and Neuenburg closes one of the last gaps in the Swiss national roads network. The new section also links the A5 and A16 Trans-Jura motorways and the T6 going towards Bern, which were built decades ago running from three directions to the outskirts of Biel.
The extinguishing water pipelines in tunnels Büttenberg and Längholz have been produced with ductile iron pipes of the vonRoll DUCPUR type with pushin joints.

District heating pipeline with water from Lake Geneva in La Tour-de-Peilz

District heating pipeline with water from Lake Geneva in La Tour-de-Peilz

Recovering heat or cold from surface water is becoming increasingly more attractive, and exploiting the enormous heating potential offered by Switzerland's big lakes is an obvious means of doing this. The "CAD La Tour-de-Peilz" district heating network project aims to use energy from the water of Lake Geneva to meet the central heating and hot water needs of around 3000 homes. The technology employed to accomplish this combines pumping stations with a network of pipelines and individual heat pumps.

Hydropower plant Lago di Tomé

Hydropower plant Lago di Tomé – high pressure pipeline DN 400

Hydropower plant Lago di Tomé – high pressure pipeline DN 400 for environmentally friendly electricity production

The Alpine lake known as the Lago di Tomé lies in the municipality of Lavizzara in the Vallemaggia district of the Swiss Canton of Ticino. The Tomé mountain stream flows from Lake Tomé into the valley of the same name and from there into the River Maggia, on the left bank just before the village of Broglio. The section between the Alpine lake, at the upper end of the valley at a height of 1,692 m above sea level, and the point where it joins the Maggia close to the village of Broglio, approximately 680 m above sea level, and hence with a geodetic head of more than 1,000 m, is of extreme interest in terms of using the water power for the production of electrical power.

Laying new ECOPUR pipes using the pipe bursting process

Schlösschen Vorder-Bleichenberg in Biberist

Nestled in the Biberist district to the south of the cantonal capital of Solothurn is Schlösschen Vorder-Bleichenberg, constructed in the 17th century by the von Roll family, aristocratic Solothurn patricians, as their summer residence. Ludwig von Roll, a direct descendent of this family, became a co-founder of the von Roll iron works in 1810, the forerunner of what has become the successful vonRoll hydro Group that we know today.

As part of a modernisation process, the Biberist district water supply company planned to replace the outdated supply pipework along Asylweg, the access road leading to Schlösschen Vorder-Bleichenberg. ...
