Rainwater can help add on a home’s water supply in areas confronting water deficiency due to shortage of rainfall or population growth overextending the existing supply. For locations with a good deal of water, rainwater harvesting can help cut back greenhouse gas emissions related to pumping and treating water from a centrally located municipal works. Rainwater harvesting can also reduce stormwater overflow from the home, freeing some of the stress on old municipal stormwater systems.

Rainwater harvesting has less energy-emphasis than other secondary sources of water like water recycling and desalination. It is also clear of minerals, thus cutting back scale buildup in the pipes, and it is free of sodium, which can be good for people on low-sodium diets or high blood pressure if utilized for drinking water.

Rainwater harvesting helps our environment and wallets.

  • Preserves drinking water by reducing the demand for municipally treated water, especially if used for irrigation throughout dry periods.
  • Reduce water bills thanks to less dependence on municipal water.
  • Aids to decrease basement flooding in older urban regions by cutting back the chance of rainwater exiting the property and getting into storm sewers (the sewers can clog up during large storms, which can contribute to flooding).
  • Helps to refill groundwater supplies by using stormwater on a position where it can penetrate into the ground and by seizing overflows in instances where the rainwater tank overflows are controlled on the home’s property by a rain garden.

Water conservation

Prior to installing a rainwater collection system, it makes good sense to be sure that you are presently using water in a wise manner around your home.

  • Exchange older, wasteful fixtures, such as faucets and toilets, with more current, water-conserving models.
  • Look for the WaterSense® logo on new products to make sure that they meet water efficiency standards set by the EPA in the U.S.

EPA established the WaterSense Program to protect the future of our nation’s water supply by offering people a simple way to use less water with water-efficient products, new homes, and services. Products are independently certified to be at least 20% more efficient without sacrificing performance. Since the program’s inception in 2006, WaterSense has helped consumers save a cumulative 757 billion gallons of water and more than $14.2 billion in water and energy bills.

Look into your exterior water use and check where you can make modifications by watering less often or using native plants for the garden that are more advantageous to take care of in dry conditions. By preserving water around and in the home, you get the most out of your rainwater harvesting system. Larger water usage means you might need a bigger system, and that means higher operating costs and installation.

A Substantial Investment

Having a rainwater harvesting system can be a substantial investment and must be cautiously done to make sure the system runs efficiently and safely. By chance, if you are a building contractor, electrician, or plumber, you will need to check with professionals for most of the installation. Even a talented DIY builder should confer with a rainwater harvesting expert and, look at the size of the tank and the area geography, additional specialists may be required.


The benefits of rainwater harvesting can be substantial. Despite living in an apparently water-rich country, we have to be conscious of the importance of clean drinking water and of the necessity to conserve it. Using treated potable water for landscape irrigation and in toilets does not make any sense to a lot of people. In comparison, rainwater use, where allowed and possible, will help us bring down our carbon footprint by cutting back the need for the energy needed for the management and transfer of municipal water to homes.

Collecting and using rainwater takes some of the work off city storm drains and can help stop flooding. When we are in a drought, the stored water lets property owners more freedom in water use than homes and businesses depending on municipal water for irrigation. In addition, it saves money.
