CHF 80m to be spent on flood defences in Lausanne
Canton Vaud is to spend CHF 80m on a 2 km long tunnel to direct potential flood water away from vital areas of Lausanne.
The tunnel will run from Prilly to Chavannes-prés-Renens.
The local government says the rivers are unable to cope with heavy rain – the possible damage caused by a major flood is estimated at more than CHF 2bn.
The work will also include redevelopment of the Chamberonne River so it will be able to cope with the extra water from the tunnel. At the same time a new bird sanctuary will be created.
The cost will be split between the Confederation, canton Vaud and the affected communes.
