To round out J. Huesa’s activities, we have an after-sales department, specialized in the operation and maintenance (O&M) of water treatment facilities.

Our working maxim is to offer our customers personalized services, with the premise of improving the facility’s performance from a technical, economic, and environmental standpoint.

These types of operations allow us to quantify and parameterize the performance of the water facility. Sampling can be either spot or composite, depending on the facility in question. We adapt to the needs of our customers and verify that they comply with current legislation regarding water use.

Industrial process feed water

The use of water in the industrial sector is so broad that, depending on its application, there are various problems that can arise. To avoid losses due to production stoppages, sampling must be carried out to assess the water problem. Potential findings:

  • Water sedimentation
  • Scale buildup
  • Different types of corrosion
  • Organic contamination
  • Legionellosis (Legionnaires’ disease)

Potable water

Whether for human consumption or for use in agri-food sector industrial processes. In compliance with current national and sectorial legislation, physical, chemical, biological, and microbiological quality controls (legionellosis prevention) must be carried out.

“We offer personalized attention to all our customers”


Periodic internal controls are carried out, as well as necessary evaluations for the study of a new treatment system or to comply with administration requirements. We specialize in effluent characterization, analyzing, among others, the following parameters: pH, conductivity, turbidity, COD, BOD5, oils and fats, metals, and other dissolved contaminants.

Reclaimed water

RD 1620/2007, which establishes the legal framework for reuse of treated water, includes the analytical profile that must be performed in order to verify that the water complies with the quality parameters for its intended use. Some of the parameters studied are: turbidity, suspended solids, microbiological contamination, heavy metals, and others.
