• Reduces Home Water BillsMost homeowners set up a rainwater harvesting system on their property to reduce their home water bills. Having your secondary water source lessens your dependence on the grid. If you include a water treatment system, you can use rainwater as a primary source to cut off a part of the typical living costs. It's also an efficient way to make your home eco-friendly.• Prevents Soil Erosion And FloodingSince the rainwater doesn't fall directly on the ground, soil erosion is lessened. The road and pavement rainwater collection systems in the cities also prevent flooding. Although water from these harvesting systems can be contaminated, it can still be filtered and used for crop irrigation.• Lessens The Use Of GroundwaterPotable water from underground is limited, unfortunately. As the human population grows, groundwater may become scarce after decades. By finding a secondary water source like rainwater, groundwater conservation is possible. This way, the planet's natural resources are protected and conserved for future generations.Although rainwater harvesting technology provides many benefits, there are also some disadvantages that innovators try to lessen and eradicate. Some of these are the following.• Requires Regular MaintenanceRainwater harvesting systems require regular maintenance to ensure health and safety. Frequent inspection is crucial to detect possible contaminants. While homeowners can take steps to maintain the system, it's still best to call the professionals for thorough periodic cleaning sessions.• Risks Of Harboring Mosquitos and Waterborne Diseases Are PresentFailure to maintain and clean your home's rainwater system can harbor waterborne diseases from bacteria and viruses. Uncovered rainwater barrels are also a typical breeding ground for mosquitos. Regular inspection, cleaning, and water testing are required to prevent these issues, especially if you use treated rainwater for cooking.• Rainfall May Be LimitedNot all regions or areas get frequent rainfall. Therefore, installing a rainwater system is not always a wise choice for everybody. If you're planning to rely on rainwater as a primary or secondary source, it's best to study how much rain you get in a year. This way, you can decide whether it's a good investment based on your location.
