Rainwater harvesting is an ancient practice that is experiencing a revival in the present day. Rainwater harvesting is the practice of collecting rainwater for irrigation, plumbing, bathing, and cooking. However, due to air pollution that contaminates rainwater, this practice was later abandoned.
Not anymore—components of modern rainwater harvesting systems involve more than pipes and cisterns. Modern rainwater harvesting systems operate with filtering and sanitation processes to make the rainwater as safe as possible for reuse. While the harvested rainwater is still not suitable for drinking, it is clean enough for washing vehicles, as well as watering lawns and gardens without risking pollution to the environment. These rainwater harvesting systems can range in size; the biggest ones can serve commercial enterprises.
Instead of concrete cisterns like those found in Carthage and Istanbul, modern rainwater harvesting chambers are made with high-density polyethylene or HDPE. High-density polyethylene is a plastic used in various applications like water and chemical containers because of its high resistance to various solvents. This makes contemporary water storage last very long while retaining its shape and chemical consistency for years on end.
These plastic rainwater harvesting systems are suitable for use in both residential and commercial properties, where rainwater runoff is best put to good use. Many people are aware that much of a property's utility bills stem from water use, but it can be quite difficult to conserve enough water to significantly cut down costs. Using free rainwater is the solution to this, and there is more than enough to reuse.
These systems for harvesting rainwater can be used in both residential and commercial properties for site irrigation. This means the harvested rainwater can be collected to sprinkle lawns and gardens, especially commercial or personal vegetable or flower gardens. Using harvested rainwater is more convenient for homeowners and business owners because they would need to pay less for water use. Watering the garden and lawn is done for free, and poses no inconvenience in summertime.
People are also aware that harvesting rainwater is a good idea for flushing toilets and urinals. Perhaps you have heard of hippies from the 1960s who limited toilet flushing to conserve water. Now, you can flush the toilet as many times as needed with no guilt because the water is free.
Perhaps the most valuable use for commercial rainwater harvesting is washing cars. Businesses can use free harvested rainwater to wash rental cars, service trucks, and other industrial vehicles. There is more than enough water to wash cars with throughout the year. For more information, see Water.EPA.gov/infrastructure/GreenInfrastructure/gi_what.cfm#rainwaterharvesting.
