Sanitary engineeringReservoirs are important infrastructural facilities that supply drinking water to the population. The majority are made of concrete, as the material is exceptionally well suited to receiving and storing drinking water without having a negative effect on its taste or composition. However, experience shows that brown patches can occur on clean mortar surfaces in tanks after only a few years of use. This can be the result of ionic currents. Corrosion protection is also a very important consideration in pumping stations or waste water treatment plants. Combining a tailormade corrosion protection concept with an active corrosion protection system extends the operating life of all structures and optimises the associated maintenance costs.
