We supply a wide range of below ground rainwater tanks, in a choice of materials. For the widest choice, GRP tanks are available in sizes from 1500 litres upwards. We also have a limited range of low-profile plastic below ground tanks.
Most tanks for domestic use tend to be up to 7500 litres; though occasionally more. For larger commercial installations, tanks can be much larger; anything up to 100,000 litres is possible. All our GRP tanks are supplied pre-fitted with a calmed inlet and an overflow trap with a built-in backflow prevention device. Backflow prevention is a requirement of BS 8515, so by including this feature in our tanks, you don’t need to worry about adding this to the drainage run.
