OUR ENTITIES :

Abattoir Public du SIGE

The Abattoir Public built in Clarens was commissioned in 1911. It underwent transformations in 1971, 1995 and 2002.

The latest transformations in 2002 enabled the facility to be significantly enlarged. The Abattoir has thus acquired facilities that meet modern technology and European requirements, and is ISO 22'000 certified.

SIGE Centre technique pour le service de l'eau

In order to ensure the distribution of drinking water as well as the reserve needed for fire defense, SIGE operates some thirty springs that are tapped through more than three kilometers of galleries. The annual volume of water captured by the springs is around 8.5 million m³. The water pumped from Lake Geneva represents an average of 1.5 million m³ per year.

To ensure sufficient pressure and permanent availability to users, SIGE has 32 reservoirs totalling around 35,000 m³. 19 pumping stations supply part of these reservoirs. Finally, 359 km of pipelines deliver water to users.

SIGE Centre technique pour l'assainissement

Inhabitants are connected to communal networks, which flow into SIGE collectors before reaching one of the region's three wastewater treatment plants. In order to treat nearly 13 million m³ of wastewater annually, SIGE operates three wastewater treatment plants - STEP - between Vevey and Roche. Through mechanical, physical and then biological treatment, the STEPs eliminate most of the macropollutants contained in wastewater.

The residues generated by physical and biological treatment, known as sewage sludge, are then sent to the sludge treatment plant located in Roche. The sludge is digested and then centrifugally dewatered. This process reduces the volume of the remaining sludge, which is then incinerated at the SATOM site in Monthey.

Finally, it should be noted that sludge treatment will enable the production of biogas, from which methane will be extracted and finally injected into the natural gas network.
