SCIRPE GRAND OUEST


SCIRPE Grand Ouest provisions wastewater engineering solutions using vegetated wetland systems to remove nitrates and phosphates load

Its treatment process systems are especially appropriately geared to controlling effluent discharges in Brittany’s many sensitive watersheds:

  • Standards regulating nitrogen and phosphorus discharge
  • Zero discharge in periods of hydrological drought
