Advantages and Benefits of Rain Water Harvesting

The method of collecting rainfall in a large butt or tank system is known as rainwater harvesting. A supplemental water supply for your house or place of business can be provided by rainwater tanks, which is a wonderful method to reduce water usage and costs.

What are the advantages of collecting rainwater?

Reducing water bills and other costs is the main advantage of rainwater gathering. You can save money on mains water by recycling natural water sources. This technique works well for cleaning cars, gardening, and operating appliances like toilets and washing machines. You may use rainwater right away and consume 40–50% less mains water with a fully integrated storage and filtration system.


Further benefits of rainwater collection include:


  • Zero water hardness: Rainwater from natural sources prevents the buildup of lime scale in your appliances, extending their lifetimes and lowering the need for detergents and cleaners.
  • No nasty chemicals or treatments: Rainwater can be used as drinking water after being thoroughly filtered and disinfected.
  • Ecologically sound: Natural water is renewable, untreated, and uses less energy in water treatment facilities. Excellent for landscaping, gardening, and plants.
  • Emergency water supply: A basic storage tank or integrated system for harvesting rainwater is the best option in an emergency. not a main? No issue!

Rainwater Harvesting System Types

When it comes to rainwater harvesting, there are many different types of systems to take into account. As part of a SOS Drainage & Plumbing Services survey, we will determine which option is appropriate for your home. We provide the following three choices:

Basic Systems:

Groundwater butts and standing tanks are examples of these rainwater gathering systems’ fundamental components. These tanks have a 400-liter capacity, making them a fantastic choice for smaller properties and grounds that use less water.

Aboveground Systems:

Aboveground tanks for commercial properties can be as large as 100,000 litres. An above-ground rainwater harvesting system is simpler to install and less complicated than an underground one. This big tanks may service a larger property and grounds while reducing the impact on the environment.

Systems Installed Underground:

Building an underground rainwater harvesting system requires excavation labour, although it is occasionally necessary for a large water tank, particularly if ground area is constrained or limited. This kind of system is more aesthetically pleasing and adaptable for larger properties and landscapes, albeit a pump will be needed to force water out of the tank.

Who can Benefit from a Rainwater Harvesting System?

Both residential and business premises can benefit from rainwater harvesting systems. Systems come in many shapes and sizes and can suit any requirement. The advantages are significant both financially and environmentally, especially for structures like farms, schools, and recreation centres that have large water demands.


Even more urban areas could benefit. Flooding is a big problem in some places with frequent storms, but storing extra water in a tank can significantly reduce flooding and overflow.


There are solutions for every size of property, whether you’re thinking about water harvesting for your home or your company’s premises.

Is Rainwater Collection Prohibited in the UK?

No, it is not against the law to collect rainwater in the UK. Harvested rainwater is not subject to regulation by the Environmental Agency. As long as it doesn’t hurt the environment, is stored properly, and doesn’t pollute a mains supply, you are permitted to collect and store rainwater.
