The high precipitation expected accelerated the work on the edges of the lake of La Gruyère. A discharge of a discharge could cause water pollution. Authorities must clear waste before Easter weekend.
The Guyère newspaper revealed it Tuesday: At the beginning of February, a landslide updates an old landfill near Vuippens (FR). Waste is spreading into the bed of the Gruyère lake. Car tires, bottles litter the floor. Today, the authorities are required to act quickly: to avoid pollution, the machines must release them before the rise in the waters of this artificial lake, which is carried out faster than expected.
“The first forecasts left us until May 6-7 to evacuate this waste. Given the precipitation today and tomorrow, the level [du lac] should go up faster, so we have to finish everything for April 21, “said Frédéric Bossy, hydrogeologist for the Hydrosol Sàrl company, in the RTS 12:45.
A risk of wastewater spill in the lake
When this first emergency has been settled, the second part of the work is to stabilize the slope of the discharge. A wall with anchors in the field will be built. Because less than five meters from the landfill is a wastewater collector in the city of Bulle.
“If erosion continues, there is a risk of rupture of this collector and wastewater would pour directly into the embankment and the lake of the Gruyère,” said the hydrogeologist.
The pedestrian path overlooks the place of the incident has been temporarily closed. He must be returned to hikers as soon as stabilization works are completed.
Known to the authorities, this municipal discharge was exploited until the mid -1980s. Before the landslide took a quarter of its total volume, it presented any danger.
