Local authorities manage a lot of infrastructure (schools, canteens, swimming pools, stadiums, port facilities, etc.) and public spaces (roads, markets, etc.). To meet the needs of and protect the inhabitants, they have to reconcile sanitary and cleanliness requirements with increasingly demanding environmental charters. They are therefore engaged in a transition to new disinfection solutions. The natural water disinfection offered by Olimpe’s in-line electrolysis technology provides an immediate technical and economic solution as part of this environmental transition.
