Rainwater is naturally soft and chlorine-free, so is ideal for plants and ponds. It’s also great for washing the car. Garden rainwater harvesting systems provide water that is much better for the garden than mains water. When correctly filtered and stored, there is no discolouration or algal growth. Our unique Vortex filters enrich the rainwater with oxygen so it will stay fresh for months.

Garden Rainwater Harvesting

Rainwater can be stored above or below ground depending on your requirements and available space. Below ground systems are more discrete and keep the water colder which helps to maintain quality. Below ground systems are easier to install when a property is being built, although a shallow dig tank can make this possible for retrofit applications. Above ground systems can be less costly to install as there is no digging, however they take up more usable space.

For garden taps only, our quiet, auto start-stop submersible pump provides good pressure to reach your entire garden. A harvesting system can also be connected to sprinkler or drip irrigation pipes; however it is best to consult us when planning your project as special considerations may need to be taken before selecting the best solution for some irrigation systems.
