In Europe there are still significant non-addressed water concerns, 91.4% of EU settlements have less than 2000 inhabitants, making up 20% of the total population of the EU, a large proportion of these communities still fall short of the standards in terms of wastewater purification and sanitation. In order to be able to offer a solution that is of practical benefit to rural areas both in the developed world and countries, and regions that face serious economic constraints, it is necessary to guarantee the elimination and adequate treatment of wastewater with minimum implementation costs and affordable service costs and in a socially acceptable manner. Decentralized, small-scale systems and non-conventional purification technologies such as those presented in INNOQUA offer a solution to the problem. The project will perform commercial scale deployment both in several European and non-European countries (France, Ireland, Romania, Italy, Scotland, Turkey, Peru, Ecuador, India and Tanzania).
