Prefabricated construction site water treatment — plug & play
A concrete and rapid response to your on-site water treatment needs
The challenges of effective construction site water management
On a construction site, water is never a trivial matter.
Between rainfall, dewatering, equipment washdowns and welfare facility effluents, every site generates volumes of polluted water with constantly changing characteristics. Add to this space constraints, tight deadlines and a strict regulatory framework to comply with.
That is why Nomado offers prefabricated, robust and tailored solutions, designed to adapt to every phase of your project and ensure compliant discharge — even in the most demanding environments.
The trust of the greatest
We treat all your water streams
Runoff water
On construction sites, runoff water can quickly become a source of diffuse pollution. Laden with suspended solids (TSS), hydrocarbons or other contaminants, it must be treated before discharge to the natural environment or drainage network. Nomado offers prefabricated solutions designed to manage these variable flows efficiently and in full compliance.
Dewatering water
During underground works or excavations, dewatering is essential. But this water can carry sediments, suspended solids and pollutants that must be treated before discharge. Nomado provides prefabricated and adapted systems to ensure compliant management of these unpredictable flows.
Tunnel boring water
Tunnel boring machines generate large volumes of water heavily laden with fine particles, bentonite slurries, polymers or additives. This water must be treated before discharge or recirculation. Nomado offers high-performance containerised installations to ensure solid/liquid separation, dewatering and regulatory compliance.
Concrete batching plant water
Truck mixer washdowns, mixer cleaning, skips, rinse areas… Concrete batching plants generate highly alkaline water laden with suspended solids. These discharges must be treated before release. Nomado offers prefabricated units capable of separating, neutralising and filtering this water to ensure full compliance.
