Collecting rainwater can help you to save you money on your water bills because you can use the rainwater that you collect to water your indoor and outdoor plants. You can harvest rainwater to fill your swimming pool, flush your toilet, do your laundry, cook food or drink. You need to have a special rainwater harvesting system to be able to drink or use rainwater in your home but having the system can mean that you have access to water during power outages or storms. For people who have problems with their groundwater, utility service or terrain, a rainwater harvesting system can provide them with pure water with no dissolved minerals. If you are just trying to collect water for landscaping purposes, you can create your own rainwater collection system that is less sophisticated but will allow you to collect and store water to use for watering the grass or your plants.
Rainwater harvesting systems are used to collect, store and purify rainwater so that it can be used in a variety of ways. These systems are used by individuals and businesses. You place the systems on the roof or in a catchment area when they can collect water. The systems often contain ground-level tanks where water is stored, purified and distributed. Rainwater harvesting systems contain pipes, diverter systems, cisterns, purification systems, pumps and pressure tanks. The systems collect, remove debris and contaminated materials from, store, use UV rays to purify and distribute the rainwater. Once the rainwater has gone through the harvesting process, it is safe for people and animals to drink. Some water systems are connected to the water supply so that the harvested rainwater can be immediately used for tasks such as flushing a toilet. Rainwater harvesting systems can often store anywhere from 170 to 1,700 gallons of rainwater.
If you only want to collect a small amount of rainwater for gardening purposes, you can create a simpler system to collect water. One method that many people use is to take a 55 gallon bucket, drum or barrel and place it under their gutters. Water flows from the roof to the gutters down the downspouts to the collection containers. The drums or buckets will store the rainwater for you. You need to connect the barrels, buckets or drums to a PVC standpipe and hose bib so you can divert the water to a hose. When you use this method, it is important to install screens on your gutters to keep out debris. This method works best if you have a metal roof because water moves more easily over this type of roof. Another easy method of collecting and using rainwater is to create a sloped walkway, sidewalk, porch or deck, pointing it directly towards your trees or plants so that water will naturally run off to your plants. Creating depressions in the ground can help you to naturally store the rainwater for future use and prevent flooding in your yard.
