To carry out this project we have used the contributions of:
- DSC – Cantone Ticino
- Aziende Industriali di Lugano and the cities of Alto Malcantone, Arbedo – Castione, Besazio, Locarno, Mendrisio, and Sorengo, with a penny of solidarity on the water.
- Private foundations

The local population participated with the labour force.
