Rainwater Harvesting FAQ’s  

What is rainwater harvesting?  

Rainwater harvesting is the collection of rainwater from the surface or surfaces upon which it falls. This water would otherwise have gone into the drainage system. Once collected and stored, the rainwater can be used for toilet flushing, garden watering and washing clothes using a washing machine.

Why should I consider a rainwater harvesting system?  

Water resources are under pressure in England & Wales as demand for water is rising. as a result of population, changes in lifestyles and a changing climate.

What savings can I achieve using a rainwater harvesting system?  

Any rainwater harvesting system will reduce your dependence on the mains water supply. Potential savings should be assessed on an individual basis as there are many factors that will influence this. The demand for non-potable water, the amount of rainwater that can be collected, and whether the property is charged by volume used.

Savings will be higher in commercial/industrial buildings and schools as these buildings have much larger roof areas. Non-potable water for flushing toilets and washing means payback on these systems can be recovered in quicker timescales.

Are there grants for rainwater harvesting?  

There are grants for rainwater harvesting which are available in regions of the country. These grants may help towards the installation costs of water storage tanks.

What outlets are fitted to these plastic water tanks?

The rainwater tank is fitted as standard with a BSP outlet. For commercial installations modifications including liquid level sensor assemblies, fill pipes, inlets, outlets or PN16 flanges are available to connect to existing process pipework.

Do I need a leaf filter for my rainwater tank?

Rainwater filters are important to make the water used in any rainwater harvesting system. These are used to filter debris from the rainwater as it flows from the collection roof before it enters the storage tank. Calmed inlets are used as part of the filter system. The water runs down through a pipe to the bottom of the tank.

This oxygenates the water in the tanks and helps prevent it from stagnating. When the tank is full the overflow siphon diverts the excess water to a drain or soakaway.   Our rainwater filters can be viewed here for home and garden water butts and tanks and commercial and agricultural rainwater tanks.
