Can you filter rain water and drink it?

Rainwater can be filtered for drinking as long as you have a clean catchment surface and use a suitable filter. Whole house water can be filtered with an ultraviolet filter or quantum filtration system, or you can use a gravity filter such as a Berkey water filter for drinking water only. To eliminate the odor and taste of chlorine in drinking water, you can use an activated carbon filter or a charcoal filter. This system is made of coconut shells, carbon and other environmentally friendly solutions.

The good news is that rainwater can be efficiently filtered and can be safe for consumption. Our filtered water systems can be used with rainwater tanks, but unlike water that comes from the mains, the water filters used for rainwater are specially made. Using a silver carbon block specifically for rainwater, these water filters fit our standard under-sink water filter systems, making them easy to install and maintain. Two key steps you can take to improve the quality of your rainwater are boiling and filtering it.

Filtration, such as through a domestic water filter jug, will remove chemicals, dust, pollen, mold, and other contaminants. While clean rainwater is safe to drink, it can easily become contaminated when dropped, which could pose a major health hazard. However, ozone will not remove harmful chemicals from the water supply, so additional filtration may be needed and a water test is always recommended. Consider adding a grate to the water inlet or emptying the rain barrel at least every 10 days to prevent mosquitoes from using the rain barrel as a breeding ground.

Your basic system requires plumbing work, and the building terrace outlets are connected via a pipe in an underground tank that can store water. If you already have a rainwater tank or plan to install one, consider regularly maintaining water intake areas to minimize contamination. The best and safest way to collect rainwater is through the use of storage containers specifically manufactured by a reputable company that produces steel rainwater tanks for the purpose of directly collecting rain. The size of a rain harvester must be large to meet the demand for daily water consumption during the dry season.

Although this method can be time-consuming and laborious, doing such a method is beneficial for producing clean drinking water collected from rain. In ancient Indian communities, they collected rain and stored it in tanks to drink and irrigate agriculture. 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). According to studies, about 2 million people in Peru have no access to any water supply, and those who have access to a water source are at high risk of contamination.

When rainwater is used as a source of supplemental water, homeowners should ensure that rainwater cannot enter pipes that contain drinking water.
