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.  

What are the benefits of using a rainwater harvesting system?  A rainwater harvesting system will reduce the demand for mains water and relieve pressure on available supplies.

How much water do I need to store?  The tank is often the most expensive part of the system and choosing the right size is key to minimising costs. The tank size needs to be a balance of cost and storage capacity. The tank should also overflow at least twice a year to flush out floating debris.

Does your rainwater tank need to be Fluid Category 5 Compliant?  Some rainwater tank installations need to be fluid category 5 compliment, we have a range of slimline and vertical tanks which are available.
