Spill inspection

The protection of the environment and the health of employees and local residents is an important issue that companies must take into account when using, storing or handling chemical or hazardous materials in the course of their business.

Industrial pollution originates from discharges of potentially toxic substances released by industries, as well as water discharged from factories.

To limit pollution caused by the discharge of polluting materials into water, the law has established a strict system of controls with which companies must comply.

What is

Spill inspection?

All activities (industrial or otherwise) that involve the use of water in their processes are likely to generate polluting discharges. The owner of the activity must carry out periodic measurements of the discharges in order to control that they do not exceed the limits set by the competent authority.

Discharges can be classified into two types depending on their destination and the specifications established for their control.

2 types

of discharges


Discharges into the sewage system


The activity must have a discharge authorisation from the local council of the municipality in which it is located. The control must be carried out by an Authorised Control Body (OCA) by ENAC (National Accreditation Entity) for Environmental Inspection, in accordance with the UNE-EN ISO/IEC 17020 standard.


Discharges into the natural environment: stream, river, sea, septic tank, etc.


The discharge authorisation depends on the Hydrographic Confederations and the control must be carried out by an Authorised Control Body (OCA) by ENAC (National Accreditation Entity) for Environmental Inspection according to the UNE-EN ISO/IEC 17020 standard, which is also a Collaborating Entity of the Hydraulic Administration (ECAH).

On the other hand, activities that carry out controlled or uncontrolled discharges are susceptible to groundwater controls, when so indicated in their application document (regulations, AAI, etc.) and in cases of cessation of activity associated with a soil study.
