Rainwater is an excellent resource that can be used for a wide variety of applications (gardening, laundry, bathing, drinking, etc.), as long as the water is properly cleaned prior to use. At Tristar Gutters, we know that one of the easiest ways to set up a rainwater harvesting system is to utilize residential gutter systems or commercial gutter systems. Here are some simple tips on how to use gutters to harvest rainwater.
1. Research the Laws for Rainwater Collection
Laws for the amount of rainwater that can be collected without a permit vary from city to city, with most having some form of regulation in place for rainwater collection. For this reason, it is important to look into the laws regarding rainwater harvesting before setting up a harvesting system. Homeowner’s who are looking to collect large quantities of rainwater might want to consider applying for a permit.
2. Calculate the Volume of Average Rainfall
In order to properly set up a rainwater harvesting system, it is important to know how much water will be collected when it rains. The volume can easily be measured using a rain gauge, which will allow for the proper amount for rain barrels or water tanks to be installed in the collection system.
3. Regularly Gutter Cleaning
Rainwater barrels can become infested with leaves and other unwanted debris, making it harder to clean than simply cleaning out the gutters. Keeping leaves and other debris out of the gutters will prevent an even bigger household chore from occurring.
4. Knowing the Roof’s Dimensions
Knowing the dimensions of the roof will also tell you how much rainwater can be collected on average. The rule of thumb for these dimensions is that a typical 25 by 40-foot roof can collect around 2271.25 litres of water during an average rainfall. Comparing this to any other roof will allow for a good idea of how many water tanks are needed for a system.
5. Water Barrel Storage and Protection
Water barrels should be stored on a small platform made out of a layer of cinder blocks in order to prevent the barrels from having direct contact with the ground. This will also make it easier to move and store the rain barrels, while also preventing the house’s foundation from getting wet. Rainwater barrels and tanks should also be covered to prevent debris from ending up in the water supply. Another option is to add filers into the collection system. The best type of filter to use is an aluminum filter with a fine mesh screen because it will keep mosquitoes from gaining access to the rainwater harvesting system.
