Production of drinking water

AguaDue to the increase in the demand for drinking water, more and more types of hydraulic resources are used. This means that to obtain water fit for human consumption, it is possible to come across many different situations and characteristics as regards the water to be treated.

In Drinking Water Treatment Plants (DWTP) the unprocessed water is submitted to a series of processes to eliminate substances that are harmful to human health. In conventional plants, these processes consist basically of:



  • Regulation.- A set of mechanisms which regulate the water flowing into the plant, to adapt it to the plant's treatment capacity.
  • Flocculation.- .- A process which, by means of chemical reagents, creates floccules which, when moving slowly through the decanters, are deposited on the bottom of those tanks, and then removed and eliminated in the appropriate manner.
  • Filtration.- Normally, this is done by forcing the decanted water through a bed of sand, where the particles not separated during the flocculation phase are retained.
  • Disinfection.- A chlorination process to guarantee a residual chlorine load in the distribution pipes.


TEDAGUA develops and operates Drinking Water Treatment Plants for supplying cities and towns in which we apply the conventional treatments described above, and also specific treatments and the latest technologies used in producing high-quality drinking water (chlorination using chlorine dioxide, selective nanofiltration membranes, microfiltration, active carbon treatments, etc.).
