A flexible tank for a REUSE project – Nice

Treated Wastewater Reuse (TWR) is an important lever for preserving water resources, by replacing withdrawals from natural environments and the supply of drinking water.

The city of Nice is launching a pilot project to reuse treated wastewater (REUSE) in order to reduce its consumption of drinking water. It is now storing recycled water for irrigating its green spaces and cleaning its roads in a flexible Labaronne-Citaf tank at its wastewater treatment plant.

The 100 m3 system, which is easy to install and tailored to the town's needs, was developed in partnership with Nomado (a company specialising in the design and construction of compact water treatment units). In practical terms, the Labaronne-Citaf flexible tank offers a cost-effective, easy-to-move storage solution that meets the specific requirements of a pilot project. ‘We chose this solution for cost reasons. It's a storage solution that's still cheap on a per cubic metre basis. It had to be a storage system that could be moved,’ explains Pierre Geeraert, project manager at Nomado. This flexibility is crucial for Nice, which is currently renovating its wastewater treatment plant to make it more sustainable.

The Nice project has been designed to ensure optimum management of the treated water. The tank acts as a buffer reservoir, guaranteeing water

The tank acts as a buffer reservoir, ensuring that water is available when needed. ‘The plant treats wastewater continuously, but demand for treated water, particularly at night, is currently very low. Buffer storage was therefore needed to manage production peaks in relation to consumption’, explains Mr. Béziers.
