Many homes have rainwater tanks that can become hazardous due to infrequent or improper cleaning. This article discusses some of the tips that you should keep in mind when you are cleaning your rainwater tank.
Ensure Proper Ventilation
It may be necessary for you to enter the water tank to clean it thoroughly. Make sure that the tank is well ventilated before you get into it. Proper ventilation will keep you safe from asphyxiation while you are working. Proper ventilation will also allow you to work patiently to do a good job since you won't be struggling to breathe.
Check the Tank
You should never select a cleaning method for your rainwater tank until you have conducted an assessment of the state of that tank. For example, the walls of some water tanks may be delicate due to age and wear. Using abrasive materials to scrape the walls of such a tank can cause it to develop leaks. A gentler cleaning method is therefore appropriate in such a case so that no further harm is caused to the tank.
De-Sludge the Tank
Rainwater tanks usually accumulate layers of sediment due to the contaminants that find their way into the tank as water collects within it. Sludge or sediment can cause the water to develop an odour. Microbial matter can also thrive on the sediment. Tank cleaning should, therefore, help to get rid of the accumulated sediment. The easiest way to remove the sludge is by extracting it after draining all the water in that tank. You can also siphon it in case you don't want to drain the water. Only then will you be sure that you have cleaned that tank thoroughly.
The cleaning products that you use in your tank may leave residues that can affect the quality of the water which will collect in that tank. Some cleaning products may even be harmful. Special effort should, therefore, be invested in rinsing all surfaces inside the tank to remove any trace of the cleaning chemicals that you used. Ensure that the used water from the cleaning or rinsing exercise is directed away from the foundation of the tank so that it doesn't contaminate the water inside the tank in case undetected leaks exist.
Always have someone watching you as you clean a rainwater tank. This person will respond quickly in case something happens to you while you are inside the tank. Alternatively, hire tank cleaners to repair and clean your tank in case you have discovered a structural defect that may compromise your safety.
