Many experts say that untreated rainwater may not be safe for human consumption, even though national guidelines suggest that the risk of getting sick from drinking rainwater is low. While clean rainwater is safe to drink, it can easily become contaminated when dropped, which could pose a major health hazard. A properly maintained rainwater tank can provide good quality drinking water. As long as rainwater is clear, has little taste or odor, and comes from a well-maintained water collection system, it is likely to be safe and unlikely to cause illness for most users.
While useful for many things, rainwater isn't as pure as you might think, so you can't assume it's safe to drink. Rain can carry different types of pollutants into the water you collect (for example, bird droppings on the roof could end up in the barrel or water tank). Rainwater can carry bacteria, parasites, viruses and chemicals that could make you sick, and it has been linked to disease outbreaks. However, when rainwater falls from the sky, substances in the air and the earth melt into the rainwater.
Fortunately, when rainwater penetrates the ground, it turns into mineral water. This water (groundwater) is relatively safe to drink. However, rainwater that falls to the ground is not only absorbed into the ground, but goes everywhere. If it falls on waste, it becomes wastewater, as it becomes contaminated.
It can also flow across the sea and into river systems. Well-maintained rainwater tanks can provide a renewable supply of soft, clear, and odorless water that can be used for a variety of purposes. If your home is over-sprayed with overhead chemicals, clean the collection pipe of your rainwater tank to prevent pesticides from entering the tank. However, the problem of lack of knowledge about water is not limited to our country because water management has only been processed by experts in several countries.
As bottled water goes through a “purification process,” people assume that it is the safest form of drinking water. Since Korea's water facilities are quite nice, muddy water is managed and supplied to us despite its large amount of more than one million to ten million times of yellow powder. After cleaning, it is recommended to rinse the internal walls and floor of the tank with clean water. This “first flush” can be used for washing, watering plants, or other non-drinking uses.
Proper maintenance of the tank, catchment system, roof, gutters and inlet is essential to ensure a safe water supply and is best done before heavy rain seasons. To maintain a safe water supply after the initial dose, 1 gram of calcium hypochlorite or 4 milliliters of sodium hypochlorite per 1000 liters should be added to the rainwater tank and allowed to stand for a minimum of two hours. Good quality water supply depends on proper design and installation, followed by prudent maintenance of the rainwater tank and catchment area. The microbiological quality of rainwater collected in domestic tanks will be worse than that of many public water supplies.
