The RainSava is the first complete rain water recovery system designed specifically for the British market
Each year we all face the possibility of water shortages or hose pipe bans. Yet we continue to waste purified drinking water for flushing the toilet, washing our clothes, cleaning our cars and watering our gardens. We do not need to waste our expensively purified drinking water, that is so often in short supply, on these uses. The revolutionary new Acorn RainSava is designed to help overcome this problem. Natural rainfall that falls on the roof of your property is filtered and collected in an underground tank. We then offer a number of economic options for distributing the water to the required locations around the home.
Whilst the RainSava will benefit any home, it can also be used in many industrial or commercial situations. Uses can range from cooling water to supplying water to flush public toilets in rural locations or even on campsites. Apart from the obvious environmental benefits, the increasing use of water meters will mean that the use of rainwater harvesting systems, such as these, will provide a saving on your water bill.
We are also working towards the recovery and re-use of ‘grey water’, from sinks, baths, showers and washing machines.
RainSava Component Options
Typical RainSava Layout
Underground Collection Filter Located in the rainwater pipe run after it goes underground, the unit contains a stainless steel filter that diverts the rainwater into the supply pipe to the RainSava underground storage tank. All excess water and filtered dirt particles continue in the usual way to the surface water drain. Vertical Collection Filter Similar to the underground filter but is located within the vertical rainwater downpipe before it reaches the ground.
The RainSava ‘Gold’ and ‘Silver’ systems use a submersible pump situated within the underground tank. The ‘Bronze’ system uses a separate pump, which can be located within the house or an outbuilding.
All of the systems use a pressure switch to control the operation of the pump.
The pump takes water from the tank via a floating filter. The float maintains the position the filter intake just below the surface of the water for maximum efficiency.
The system also senses the water level within the underground tank. At times when there is insufficient rain to maintain a working level, the system compensates by automatically introducing water from the mains supply into the underground tank. It is important to note that it only uses enough mains water to maintain a minimum working level within the tank.
Underground Storage Tanks
Underground storage tanks are available in a range of sizes, in both horizontal and vertical cylindrical formats. The inlet and outlet pipework connections can be located in any position to suit your particular site conditions.
We also offer a range of above ground storage tanks, which are ideally suited to industrial applications.
