Rainwater Harvesting

Rainwater Harvesting Garden Systems

At Rewatec, we believe in preserving the precious natural source, WATER. With most forecasts pointing towards drier summers, the likelihood of hosepipe bans being introduced more frequently and rising water bills is higher than ever.

Utilising rainwater is the key to ensuring your garden is well watered throughout the summer, and there are many benefits to using a Rewatec Rainwater System that make it the right choice for your gardening and car washing needs.

We have produced 3 packages to ensure we have the right solution for you, each package is available in our round and flat tank styles. Minimise the disruption and save money on the installation with our F-line tank!

Rainwater Facts

  • Rainwater is much better for your plants than mains water, and not subject to hosepipe bans
  • The average UK house can yield as much as 64,000L of water a year from the roof! (that's 213 water butts!)
  • Water meters are becoming mandatory, and water costs are likely to increase a lot in the future due to repairs needed and water shortages. Using rainwater will save your metered mains water and therefore save you money
  • Rainwater harvesting adds a nice selling feature to your property!

Why store rainwater in a Rewatec underground tank?

  • Underground storage eliminates growth of algae
  • The water can easily be filtered before entry, making it cleaner
  • You can have large amounts of storage without taking up room in your garden
  • You'll be able to use the water to wash your car
