Rainwater Harvesting Solutions

Our Rainwater Harvesting Systems are designed to accommodate farms, homes, gardens, industrial settings and multi-house dwellings, making it virtually impossible for you not to find exactly what you’re looking for.


What is Rainwater Harvesting?

The process of rainwater harvesting is straightforward.

A rainwater harvesting system collects, filters and stores rainwater.

When rain falls onto the roof of a property, it’s channelled through the gutters and downpipes into a rainwater tank via a filter.

The filter allows rainwater to be cleaned before it passes through to the tank – preventing leaves, moss or debris from entering the tank. 

The water within the system is then stored reliably in the rainwater storage tank until it can be diverted to the required place. This could be an outdoor tap for garden irrigation or car washing, to a washing machine or a toilet for flushing.

Our rainwater harvesting systems are designed to accommodate the needs of domestic, commercial and industrial customers, including (but not limited to) farmers, homeowners, gardeners and landlords.

Commercial Systems

Rainwater tanks can also be used for commercial rainwater harvesting.

A rainwater harvesting system can collect, filter and store rainwater from the roof of a commercial building, helping businesses to achieve their goal of focusing on water independence. On top of this, a rainwater storage tank can offer a cost-effective solution for various businesses and their buildings.

Harvesting rainwater will allow commercial businesses to work towards sustainability and will meet the requirements of clients and buildings, alike.

The contents of the rainwater collection system can be used for toilet flushing, irrigation and vehicle washing – reducing reliance on mains water supplies. This allows commercial clients to reap the benefit of reduced carbon emissions and savings on their monthly water bills.

How can you benefit from Rainwater Harvesting?

Rainwater harvesting is an effective and eco-friendly solution for increasing the efficiency of your water usage.

Below are just some of the ways you can benefit from using rainwater tanks.

  • Reduced water consumption
    The water that is stored inside the rainwater harvesting tanks can be used for various systems, including toilet flushing, outdoor taps and many more. Finding appropriate rainwater harvesting solutions will ultimately reduce the amount of water that you use, therefore making your bills cheaper.

  • Simple installation
    Installing rainwater tanks is quick and easy and, if required, we can also provide an installation service. The rainwater harvesting system is managed carefully by our technical experts and any of the equipment that we supply is tried and tested to guarantee the best results.

  • Environmentally friendly
    Rainwater doesn’t contain any nasty chemicals, meaning less energy is required at water treatment centres. This helps to reduce carbon emissions, which is great for the environment – not to mention gardens and landscaping.

  • Emergency water supply
    Having access to a rainwater harvesting tank can be a real bonus, especially in case of emergencies. If there is a water shortage or no mains nearby, you can use the water stored in your rainwater collection system. What’s more, once natural rainwater has been properly filtered and disinfected, it’s usually safe to drink.
