Rainwater Harvesting

Water, or the lack of water, is becoming an ever increasing issue in the UK and needs to be addressed as a matter of urgency.

Climate change, over extraction of water resources and population growth are largely to blame for the current and future areas of water stress in the UK. Indeed, we are seeing an increasing use of Hosepipe Bans being implemented by a number of Water Companies in the UK as part of the measures to combat this very real problem.

New technologies like rainwater harvesting and greywater recycling enable us to reduce the water consumption by using resources that are mostly available to all of us – coming from the roof or draining from our showers, baths and hand wash basins.

Why not make use of them?

 

 

 

 

 

 

 


Best water quality due to simple three step filtration/separation

Rainwater is collected from the roof and collected via the gutter or siphonic drainage system. Before entering the storage tank, the water is filtered. Large particles such as leaves, moss and twigs are separated. The filtered water is fed into the storage tank via a calmed inlet, thus ensuring that the water inside of the tank stays calm and small particles can settle to the bottom or float to the surface. The water is then pumped to the serviced appliances via a floating extraction which always takes the water below the surface and above the bottom of the tank. The floating extraction has another filter to avoid fine suspended matter entering the supply.

Water quality

If a rainwater harvesting system is professionally designed and installed, the water quality should be more than sufficient for non potable applications such as WC flushing, laundry etc. More de-tails on the water quality are available in BS8515:2009.

 

 

System Components

High quality, compact & easy to install

 

1) Pre-Filtration – Filtering out larger debris such as leaves

2) Rainwater storage tank – collects and stores the incoming rainwater

3) Supply pump (optional) – supplies water from storage tank to control unit unless tank is close enough to tank to prime directly

4) Aqua-Control – Control unit with integrated booster pump set and mains water back-up according to BS8515

5) Expansion vessel – Reducing run time of pumps and protecting equipment against small leaks

6) Soak away (optional) – Infiltration system with pre-sedimentation pit
