Veolia and SADE have joined forces to provide an innovative and ethical solution to reusing treated wastewater to supply drinking water to districts in the department of Vendée. Circular water recovery programme Its aim is threefold: to provide an additional solution in areas with high demand in summer and where there is an imbalance in conventional resources, to operate a circular system of water use by sending treated wastewater to reservoirs rather than discharging it into the sea, and to validate the refining process to obtain very high-quality water and demonstrate its safety for the receiving environment. Rather than being...

Proposal of a customised solution To ensure both the water-tightness of the 6,000m3 tank and the recovery of the considerable amount of matter suspended in the vegetable washing water, SADE Engineering and the Rennes Regional Division designed and sized a decanting channel comprising a damping chamber and two decanting compartments that are successively refilled by overflows, over the...

including redeployment of its wastewater systems from now to 2050. The cliffs in Ault are regularly retreating, under repeated attack from the sea wearing them away from the bottom, and rainwater infiltration eating away at them from the top, plus the combined effects of freezing and thawing. According to estimates, in some places, they are losing 30 to 50m every 100 years. Faced with this danger, the town was added to the Picardy cliffs risk prevention plan (prefectural order of 6 June 2013), which addresses the risk of coastal erosion and predicts changes to the coastline, as well as making...
