Before the rainy season begins, make sure to clean the tank, entrance pipe, roof, and roof gutters thoroughly. This will remove any dirt or buildup that could affect water quality. It’s also very important to avoid using containers that have ever stored harmful substances like oil, pesticides, or any toxic chemicals, as these can make the water unsafe to drink.
When the first rains of the year come, let them wash through the tank to clean it. This first rinse helps clear out any remaining dust or dirt. After this, cover the tank and put a filter or screen over the inlets where water flows in. This keeps out insects, leaves, and other debris, and it also prevents mosquitoes from breeding in the water.
For the cleanest water, it’s best to take it out through a tap if possible. This avoids dipping into the water, which can introduce dirt. If you need to use a bucket or other container to scoop water out, make sure the container is clean each time. This reduces the risk of germs or dirt getting into the water.
For added safety, you can use a water filter that connects directly to the tank. It’s also helpful not to stir or move the water in the tank. This way, any dirt or germs that may have entered will settle at the bottom.
Also, remember to sweep the roof from time to time to keep dirt from washing into the tank when it rains. Following these steps will help keep your rainwater safe and clean for drinking and other uses.
