Souprosse – France
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.

The issue faced by our client

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.

The project

Working entirely alongside our client, we designed a compact, containerised iron removal unit for a flow rate of 80m3/h.


in-line injection of chlorine

4 x sand filters

+ redox media

Input/output analysis

chlorine, pH, redox

Human-machine interface

with communication via the supervision in place

Backwash pump

Reagent storage and retention

Constructed in record time, given the urgency to supply quality water to its customers, our design teams were mobilised in order to size a process which could be easily and economically operated and delivered quickly. This unit was designed so that it could easily be remobilised at another production site.

To summarise, Nomado:

  • Completed design studies
  • Provided a compact system
  • Performed on-site commissioning
  • Reference standard: French Decree n° 2007-49 of 11 January 2007 on health safety of water intended for human consumption.
