Past edition

The 1st edition of the #prixalpiq brought together 18 sustainable water management projects sponsored by 21 Valais communes. The projects submitted address issues from many fields, such as agriculture, energy and tourism. They propose concrete solutions for irrigation, access to drinking water, wastewater management, water pollution reduction, energy production and automation, in order to preserve water resources and optimise their management. The judging panel, composed of 12 Valais personalities, selected the winners of this first edition.

Winner 2021

  • Project initiators: Commune of Salgesch, Cordonier & Rey SA

The project, developed by the company Cordonier & Rey SA and sponsored by the commune of Salgesch, addresses the problem of water shortage affecting the commune. The objective of this pilot project is to reduce the water needs of local agriculture, as part of the development of the Lienne-Raspille project. The latter aims to address water shortages in 7 communes in the Sierre region (Icogne, Lens, Crans-Montana, Noble-Contrée, Sierre, Salgesch and Varen) by storing water in the Tseuzier dam.
The #prixalpiq will enable the commune of Salgesch to set up a new irrigation system that will reduce water requirements by 20 to 40%. This state-of-the-art project will replace obsolete irrigation systems with an innovative drip irrigation system coupled with resonant water treatment that measures soil moisture in real time and provides access to a coordinated irrigation schedule (Aqua4D technology).
Once the pilot phase is completed (one agricultural season), it could then be replicated in the other communes of the Lienne-Raspille project to optimise their irrigation networks. On a larger scale, it will enable communes to work together to respond to the effects of climate change.

“Winner of hearts” 2021

  • Project initiators: Commune of Val de Bagnes, Droople SA, in partnership with EPFL and ALTIS Groupe SA
  • Project name: WaSTeLeSS (Water savings and termination of Leakage through Smart Sensors network)
  • Aim: To raise awareness of water use in Val de Bagnes and reduce drinking water consumption by up to 20%
  • Reward: CHF 10,000 
  • Contact:

Droople SA's "WaSTeLeSS" project, developed in partnership with EPFL and ALTIS Groupe SA and supported by Innosuisse, offers an innovative service – a digital platform for the management of water-consuming equipment – that allows for more transparent and efficient management of water and its consumption. The service, based on a consumer-pays model, reduces overall cold and hot water consumption in buildings where it is used by an average of 20%. Thanks to #prixalpiq, this platform, already operational in a test environment, will be deployed at the Espace Saint-Marc in Le Châble – a space that welcomes more than 40,000 visitors per year – in partnership with the commune of Val de Bagnes. Visitors will be informed about the amount of water they use and will therefore become aware of the impact of their actions. It should be noted that user awareness can reduce water consumption by 10 to 15%. 
The project establishes a new model of collaboration with the water and energy provider and distributor ALTIS Groupe SA, in order to offer services that correspond to the needs of the final consumer according to the "consumer-pays" model.
