Le Syndicat Départemental d’Équipement des Communes des Landes (commonly known as “SYDEC”) is public body covering 327 towns in the Landes area, numerous inter-communal cooperation establishments, the County Council and the Aquitaine Regional Council.

Seven towns in the French county of the Landes receive water supply via a water borehole located in the town of SOUPROSSE. After pumping, water is chlorinated by injection gaseous chlorine into a storage tank. The quality of the water resource suddenly deteriorated in terms of iron, exceeding the regulatory reference quality threshold value of 200µg/l, regularly causing the water to become discoloured. Refurbishment works at the site have been programmed over the next few years but whilst waiting for these works to start the Sydec wished to install a mobile iron removal unit.
