Knowing how to stop erosion in water tanks is essential for those who have concrete water tanks at their facilities. In recent years concrete water tanks have become popular as they are cheaper and have better accessibility compared to steel water tanks. Although concrete water tanks are strong and durable, they are still susceptible to erosion. So, in this article, we will talk you through what you can do to prevent water tank erosion in your concrete water retaining structures.
Why Erosion Should Be Avoided
Concrete water tanks are open to deterioration and erosion if they unprotected when coming into contact with chemical solutions. If your water tank is not correctly lined even the mildest of chemical products can cause erosion which can then lead to the concrete degrading. If your water retaining structure is at the point of degradation, the excess aggregate created will form the ideal breeding environment for bacteria. The result of this will cause your water to become contaminated which will, therefore, mean it is no longer safe for function. If your tank is storing drinking water/potable water, your water supply could be affected by potential carcinogenic properties, so it will no longer be suitable for its use.
Ensuring Your Water Tank Lining is Sufficient
The best way to prevent erosion in your water tank is to ensure that is correctly lined with an effective lining which will protect the concrete substrate of your water retaining structure. Here at COVAC, we can ensure that your water tank is lined properly so you can avoid the issue of erosion. A long term solution into eliminating this problem is to apply a new ACOTHANE DW coating which has a high impact resistance against erosion. Our coating will leave you with a finish that will be easier to inspect and better for the functioning of your water tank.
Draining and cleaning your water tank is a crucial part of preventative maintenance, however, you must carry out maintenance checks before you start the cleaning process. These checks consist of checking the structural supports under the tank along with pipework and supports within the tank. You must also look out for any leaks here and also check overflows that are fitted for any damage. After these checks, you will be able to start the cleaning process.
Cleaning your water retaining structure is essential to ensure that the water within your tank remains clean and free of bacteria. Ideally, you should clean your water tank at least once a year to keep it clear from any algae, silt and bacteria, as this can build up in your tank over time. To properly clean your tank, you will need to drain it before cleaning the interior walls and finally finishing by disinfecting the tank.
