Our Activities

We know how to treat all types of water to achieve the requirements of its final use: waters suitable for human consumption, irrigation and industrial use or discharged into public watercourses. We design, build and operate all types of treatment facilities, providing consulting services tailored to each client. More than 25 years building water treatment plants are proof of this.


Drinking water treatment plants

Water resources are usually very diverse (deep wells, rivers, dams, etc.). Besides, many other factors such as soil composition and climate, causes a great diversity of types of water to be treated. All this means that we find a great variety of water characteristics that demand a spe-cific design of the treatment plant.

In Drinking Water Treatment Plants (D.W.T.P.), raw water goes through a series of process in order to remove substances that may be harmful for human consumption. It is also required that the product meets the standards adopted in the country.

In TERSAQUA we develop and operate Drinking Water Treatment Plants in which we adapted our knowledge to client needs. For this purpose we use all the available technologies in the market.
