To remove the smell and the taste of chlorine in the drinking water, you can use an activated carbon filter or charcoal filter. This system is made of coconut shells, carbon, and other eco-friendly solution. The last method of filtering rainwater is through solar pasteurization.What are the types of rainwater harvesting?
There are three main types of rainwater harvesting system: direct pumped, indirect pumped, and indirect gravity. In certain situations it may be possible to have a purely gravity system; though such occasions are rare.How do you calculate rainwater collection?
To calculate how much rainwater can be harvested, multiply your rainfall (mm) by your roof surface area (m2) being used to catch rainwater. The resulting number represents how many litres of water you can expect to collect.How can we purify rainwater?
You wind up boiling the water first, then adding several drops of chlorines into a quart of rainwater.

Harvesting rainwater checks surface runoff of water and reduce soil erosion.How much rainwater storage do I need?
A general “rule of thumb” is to assume it rains every two weeks. So take your maximum potential annual rainwater collection and divide it by 26 (the number of fortnights in a year).
