BHS Underground Rainwater Storage Systems

 -> Department: Water Butts (show all categories in department)

underground rainwater storage system

Rainwater harvesting systems are designed to store and redistribute rainwater. Ideal for areas of low rainfall and those with water usage restrictions in dry periods. In these areas the storage of rainwater can be extremely useful. The system is easily connected to a rainwater down pipe where a simple connection is made to divert the rainwater into our high strength polyethylene storage tank either for underground storage on new build or renovation or above ground storage for existing properties (as shown below). It comes in various volumes from 1150 litres upwards. Multiple tanks can be slaved together to create any required storage capacity.

Each system is supplied complete with a submersible pump that can be used to extract rainwater from the underground tank. Water can be supplied to a hose pipe at pressure via this pump and used in the garden or for other purposes such as washing a car.

Example of use: On an average 3 to 4 bedroom property the tank would typically be sited at the front or back of the development, however land permitting you could connect both the front and back rainwater down pipe’s at a mid point As an example a typical area of pitch or side of a roof on a detached or large semi would be around 35 to 50 sq m and would generate between 150 and 250 litres per hour of rainwater from an average U.K. storm. So our smallest 1150 litre unit would take around 4 to 8 hours to fill in constant rainfall. Once the tank is full it will go to overflow. This amount of water would give a reserve water supply from the system for use from a hose or sprinkler onto your garden or connection to a jet wash for around 3 to 4 hours, based on a large car wash machine using 450 litres per hour.

Installation of a rain harvesting system reduces the requirement for tap water, saving money where supplies are metered. More and more UK homes are being converted to metered supplies following the introduction of new government legislation that gives water companies the right to compulsorily meter their customers in areas of water scarcity. Storing rainwater for use in the garden is also environmentally friendly and can prove especially useful when hose-pipe bans are enforced.

The tanks used in these systems are available in several sizes and the systems offered consist of several of these unit tanks linked together to obtain the desired storage capacity.

Please note these tanks are not suitable for the storage of drinking water. Tank colours may vary from those shown.
