Wastewater treatment

Nomado designs and builds containerized treatment units (Waste Water Treatment Plants or WWTP) for wastewater purification.
Collected wastewater is treated before it is discharged into the environment.
Our solutions
Water is treated in accordance with public health and environmental requirements.

A concept of custom design

The solutions and equipment that we offer perfectly adjust to variations in the pollutant content of the wastewater or a change in its processing load.
Flexibility is a key feature of our compact solutions that can be adapted over time to needs that may appear after design.
We design treatment systems that can accommodate a range going from 50 PE (1.25m3/h) to 5,000 PE (125m3/h). Our experts will listen to your needs and help you determine the treatment unit that best suits your project.
We can assist you each step of the way:

  • Pre-study
  • Obtaining authorizations and preparing regulatory documentation
  • Design and construction of the unit
  • Commissioning
  • Operator training
  • Operation and Maintenance


Two wastewater categories exist:

  • Domestic or urban,
  • Industrial,

Domestic (or urban) wastewater includes domestic waste (i.e. grey water: shower/bath, kitchen, floor cleaning,…) and raw sewage (i.e. black water: toilet). These waters contain minerals and organic matter, suspended or dissolved.


Regulations require wastewater to be treated before being discharged into the environment. This is referred to as a sewage or wastewater purification system. Treatment aims at removing pollutants from the water so as to have no impact on the environment upon its discharge. Discharge criteria may vary and can be more or less stringent depending on the location (environmentally sensitive area, classified Natura 2000 …). In some cases an impact assessment may be required.
In France it is the ordinance of the 21st of July 2015 that lays down the obligations with respect to community or private wastewater sanitation systems for population equivalents (PE) of more than 20.
Before installing or modifying a wastewater treatment plant requests must be filed, and authorizations obtained from the regulatory authorities.

  • In France, for population equivalents of under 200, it is SPANC (non-municipal wastewater system public service) that is in charge of authorizing and inspecting the facilities.
  • In France, for population equivalents of under 200, it is SPANC (non-municipal wastewater system public service) that is in charge of authorizing and inspecting the facilities.
    For population equivalents greater than 200 it is DREAL (environment, land development and housing department or DDTM (land and sea development agency) associated with the Water Police that process the applications. In the latter case depending on the nature of the project you can either simply inform the authorities” or file a full request under the French Water Law. The sizing unit for wastewater treatment plants is the “population equivalent” or PE as defined by Article R2224-6 of the French Local Authorities Code. This allows for the easy determination of production capacity with respect to expected pollution load.


Whether in France or internationally, our water treatment experts are available to help you define the treatment unit that will best suits your needs.
