Since January 2015, Latitude has worked on the participatory design project Ilot d’Eau and in the diagnosis Enquête sur les citernes d’eau de pluie (Inquiry on the rainwater tanks) in the frame of Les Chemins solidaires de l’eau, a project submitted by Latitude with EGEB and some local committees of inhabitants for the Contrat de Quartier Durable Abbaye (Forest) and financed by the Brussels-Capital Region. These two projects aim at raising awareness among the inhabitants and the city users about the consequences of private and public management of rainwater in the urban tissue. The first Latitude’s public action is the Enquête sur les citernes d’eau de pluie, a diagnosis about the rainwater tanks existing in the area. A table has been arranged in the public square St. Denis (Forest) during the general assembly of the Contrat de Quartier Durable Abbaye and for the following two weekends during the local market. Inhabitants were invited to fill in a questionnaire, to indicate their own rainwater tank – real or imaginary – on the map of the Contrat de Quartier, to express if they had water-related problems in their parcel, to describe the measures they take to face the problems, to tell how they use water at home. Crossing public archive information and citizens’ knowledge allows to have an overview of the existing situation and understand the awareness of inhabitants about their own neighbourhood’s equipment. The result of the work was the production of a map and of a maquette representing all the existing and former tanks in the private spaces of the neighbourhood. In addition, Latitude collected all the historical and current technical drawings about water tanks into a single document.
