Water frugality: Uses and sharing the water resources
Following on from the Visible Invisible Water - Eau Visible Invisible conference organised by Apur as part of the third Ile-de-France Architecture and Landscape Biennale in Versailles, this workshop explored the challenges of sustainability.
The workshop first looked at the reduction in consumption. Frugality means consuming less water. Discussions questioned this objective put the simplest terms, in regard to the economic assessment models of the ecosystem based on the volumes consumed. Secondly, discussion turned to the links between frugality and circularity taking into account regulatory changes which give greater importance to the different types of water and the cycles on which they depend and to which they contribute. The Grand Paris metropolitan area has its own specific characteristics which vary depending on the scale of analysis and particularly involve the management of low-water flow in the River Seine and the reuse of treated wastewater. Finally, water frugality issues were looked at by stakeholders from the point of view of their usage. Expansion of wastewater networks and work carried out to combat flooding are central to indicating, high levels of urbanisation and soil sealing. The adaptation of buildings and public and private spaces and their facilities is increasingly incorporating new approaches to water.
The various contributions made, by the key players in the domain of water, present an unprecedented evaluation and shared overview of metropolitan challenges involved in implementing the Plan Eau, emphasising both the ambitious objectives and highlighting exemplary initiatives.
