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 non-potable applications such as 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 rises due to the increase in the population, changes in lifestyles and a changing climate.? 

What savings can be achieved by 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, factors which will influence this are the demand for non-potable water, the amount of rainwater that can be collected and whether the property is charged by volume of volume used.? Savings will be higher in commercial/industrial buildings and schools as these types of buildings having much larger roof areas and a much greater demand for non-potable water. 

Are there grants for rainwater harvesting? 

?There are?grants?for rainwater harvesting which are available in regions of the country.? 

Equipment Mounting and Customisation 

The 10000-litre rainwater tank is available with tank modifications including Liquid level sensor assemblies,?fill pipes, BSP threaded inlets, outlets or PN16?flanges.   Our range of rainwater filters can be view here.  Rainwater filters are important to make the water used in any rainwater harvesting system and 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 as the water runs down to the bottom of the tank and fills the tank through the calmed inlet at the bottom of the tank. This oxygenates the water in the tanks and helps prevents it from stagnating.  When the tank is full the overflow siphon diverts the excess water to a drain or soakaway.
