Cleaning and waterproofing of cisterns and cisterns

The problem

Generally, the water that accumulates in cisterns comes from rainwater.
In the case of rainwater, this is collected by the roofs and / or gutters, which usually do not have a good cleaning, since bird droppings and many types of particles such as pollen, sand , leaves, etc.
In the case of water from the network, it usually does not have problems, since it comes from the public water supply company in question, which carries out exhaustive controls on the quality of the water; but, even so, as it runs through pipes, and certain contaminants and particles may be on the walls of these, carry out cleaning and disinfection to ensure that the water present has good parameters. The parameters that indicate the bad state of the water are the smell, color and taste of the water.

For your health and for your economy

The passage of time, together with changes in temperature, generate bacteria and pathogens that contaminate drinking water both in the cisterns and in the reservoirs. In addition, cracks may appear that cause leaks that can scare the bill, put structures at risk and cause humidity.
