Everything you need to know about rainwater harvesting systems, water storage tanks and sustainable water reuse.
A rainwater harvesting system collects and stores rainwater, typically from building roofs, for reuse in suitable non-drinking water applications.
Rainwater is directed through gutters and downpipes into a storage tank, often passing through a filter to remove leaves, debris and other contaminants.
Depending on the system, the collected water can then be supplied to garden irrigation systems, toilets, washing machines or other suitable applications.
Our range includes complete rainwater harvesting systems, underground storage tanks and accessories for domestic, commercial and agricultural use.
Harvested rainwater can be used for a variety of non-potable applications, helping reduce reliance on mains water.
Common uses include:
- Garden watering and landscape irrigation.
- Toilet and urinal flushing.
- Vehicle washing and outdoor cleaning.
- Agricultural irrigation.
- Washing machines, where supported by a suitable system.
- Certain commercial and industrial applications.
The intended use will determine the type of rainwater harvesting system, filtration and pumping equipment required.
Harvested rainwater should not be used for drinking or food preparation without appropriate treatment and verification of water quality.
The correct rainwater harvesting tank capacity depends on your property's roof area, local rainfall levels, available installation space and expected water consumption.
For example, a system used exclusively for garden irrigation may require a different storage capacity from one supplying toilets and washing machines throughout a property.
Our range includes smaller rainwater storage tanks alongside larger-capacity systems for domestic, commercial and agricultural applications.
When choosing a tank, it's important to consider both the amount of rainwater you can collect and how much you expect to use.
If you're unsure which capacity is suitable, our team can help you identify an appropriate product.
Above-ground and underground rainwater harvesting tanks provide different storage solutions depending on your available space and installation requirements.
Above-ground tanks are typically easier to access and are commonly used for garden watering, irrigation and general outdoor water storage.
Underground tanks are installed below ground level, allowing larger quantities of rainwater to be stored without occupying valuable surface space.
Underground systems are particularly popular for new-build properties, landscaping projects and complete domestic rainwater harvesting installations.
The best option depends on your required capacity, available space, intended use and installation conditions.
Yes. Rainwater harvesting systems can help reduce mains water consumption by collecting and reusing rainfall for suitable non-potable applications.
Using harvested rainwater for activities such as toilet flushing, garden irrigation and vehicle washing can reduce the amount of treated mains water required.
However, actual savings depend on rainfall, storage capacity, water usage, system efficiency and whether your property has metered water charges.
Some systems also require electricity for pumps and regular maintenance.
Choosing an appropriately sized system is important for achieving practical long-term water savings.
Yes. Regular maintenance helps ensure rainwater harvesting systems continue operating efficiently and reliably.
Maintenance may include inspecting and cleaning filters, removing accumulated debris, checking pumps and inspecting tank connections.
Underground and above-ground systems may have different maintenance requirements depending on their design and components.
The frequency of maintenance depends on the system, surrounding environment and amount of debris entering the collection area.
Always follow the manufacturer's maintenance instructions to help maintain water quality and reliable system operation.
Many of our rainwater harvesting tanks and systems are supplied directly from the manufacturer, with delivery lead times varying depending on the product and availability.
Free delivery is available on eligible products to most mainland UK postcodes, although additional charges or restrictions may apply.
Larger tanks and systems may require specialist transport, suitable delivery access and appropriate offloading equipment.
