About Rainwater Harvesting

Our rainwater harvesting systems are available for the home, garden and commercial use. You can install these systems in to existing buildings as well as new builds.  All the parts and fittings used in our rainwater harvesting systems are standard UK fittings available in most hardware stores.

All our rainwater tanks / Water Butts have BSP outlets which are perfect for adding a standard garden brass tap to.  Our BSP outlets are available from ¾” to 2” on selected water tanks. Other outlets can be added to the tanks after production however they be plastic tank connector instead of the brass BSP inserts used in the manufacturing process. They also have a vented screw down lid which is available from 4” to 16”.

All the rainwater harvesting system and water butts are made in the UK which gives us the advantage to offer a next day if required (depending on stock levels).  This also means in the unlikely event of a replacement tank/part be required, we can get one to you quicker than most.

Rainwater Harvesting System

The basic principles involved with our rainwater harvesting systems are as follows; The rainwater falls on to your roof and follows its natural path down the guttering and then normally straight down the drain. At the this point you divert the rainwater into one of our inline cylindrical filters this then flows out of the filter and into the underground water tank. From here it depends on what you want to use the rainwater for, as to what pumping system you would need. If you were using the rainwater for a domestic purpose such as flushing the toilet, then you would need a stainless steel booster pump kit.  The water pump would be installed in your house or a place where it can’t get damp, wet and protected from frost, this would then have a pipe running down to the water tank which would suck water up through the pump and send it to where it needs to go. Attached to the pump is a small pressure switch which would turn the pump on when the tap or outlet is opened, it would then turn the pump off when the tap or outlet is closed.

If you want the rainwater collected to be used in the garden your would need a different pumping system, however you can run both domestic and garden water systems off of the pumping system mentioned above. However if you only want to water the garden and not have any rainwater domestic supplies then there is a simpler system.  With the garden system you would have a submersible water pump installed in the underground water tank, this would then be connected to a pressure switch which you install into the provided pressure switch house (or you can install anywhere else providing it is protected from the elements). Connect a brass garden tap to the pressure switch via the flexi tap connector provided and wire the pressure switch to the pump via the mains and this will work in the same way as the domestic system.
