Run-off water

Nomado supplies systems for treating run-off water from worksites or platforms.

A solution adapted to specific requirements.


In industrial activities, civil engineering sites and storage activities (e.g. storage of galvanised parts or sea containers), various particles and liquids, in particular hydrocarbons, can often be found all over platforms.
This is why during rainfall events these elements trickle and mix with stormwater generating pollution.

Stormwater is subject to regulations and is required to be treated before being discharged into the natural environment.

Our approach

First, effluent needs to be characterised in order to determine the level of pollution. The main pollutants present in stormwater being hydrocarbons and SS (suspended solids), Nomado provides hydrocarbon separating facilities and particle settling tanks.

Then an analysis of the worksite is carried out because often, depending on the terrain, a single treatment facility is not the most appropriate answer. Thanks to this study, an optimised treatment solution can be selected and implemented: containerised or dispersed.

Polluted stormwater is channelled and cleaned through the treatment process, ready to be discharged into the natural environment.

Nomado has significant experience in studying, sizing and constructing these treatment systems. We can assist you.

The solutions that we offer adjust extremely well to variations in the quality of the water to be treated and the quantity of the load that it contains. Our treatment units are integrated into sea containers or mounted on SKIDs thereby reducing production times, installation times on site and civil engineering costs.
Sheet metal work and welding of the hydraulic structures are performed directly inside the container. Waterproofing is ensured by a seal made of special coatings that constitutes a perfectly monolithic block. It prevents water from coming into contact with the structures. The Coatings’ properties are always chosen in accordance with the project’s specifics (Health compliance certificate, WRAS, aggressiveness of reagents or water, etc.).
