NILSA is a Navarra Government owned company in dependence of the Local Administration Department. Its aim is to give technical support to local entities in the implementation and management of municipal services related to depuration of waste water and other basic infrastructures.

Its compromise with society is translated into a respectful management with the environment that searches technical efficiency. Our working in D+R backs up our compromise and reinforces our role in a society that has water as a main character of the public debate.

More than 80 projects all along Navarra and almost the whole of its waste water treated give proof of its management quality.
