Contaminated Water Diverter
The Contaminated Water Diverter (CWD) is a computerised pre‐tank filter – the only computerised first flush diverter on the market today that we are aware of. The Contaminated Water Diverter (Aqua Diverter) also comes in a manual (i.e. non-computerised) model system.
Why Do I Need It?
Over time a house’s guttering accumulates a lot of debris – dirt, leaf material, loose bird faecal matter, etc. – when it rains that is all washed into your water tank.
The Contaminated Water Diverter Tank system (CWD) prevents this material entering and contaminating your water tank by temporarily disconnecting the roof from your water tank. The contaminated water is siphoned off and goes to waste.
It makes sense to prevent debris getting into your water tank – it saves on cleaning and maintenance, and means quality water from any tap in your home.
How Does the CWD Work?
There are two ways water gets from the roof of your house to your water tank. The first is a siphon system – the pipework goes below ground then up into your water tank. The second is a direct system – the guttering pipework runs from the roof overhead and straight into your water tank.
The CWD can be connected to any water tank system preventing all those “gutter nasties” from getting into your drinking water. It can even be adapted to fit underground water tanks.
In simple terms, when the CWD is in “flush mode”, the head of water between the water tank and the in-line filter, rushes down the downpipe. This rinses the in-line filter and drops all dirt and debris into the bottom of the sediment tank. This is then vacuumed out to waste by the CWD controller through a siphon pipe.
It’s simple, it’s automatic, it saves on maintenance and cleaning and it gives great tasting water, making contaminated water a thing of the past.
Features of the CWD
- Battery backup for power outages.
- Manual open & close function (great when cleaning the roof).
- Customisable programming – control interval timings between flushes.
- “Dry mode” for a complete manual flush when not triggered by rainfall.
- Self-rinsing in-line filter.
- The valve and actuator motor are 12v and CE Certified.
- Electricals are housed in aluminium and stainless steel components.
- Maintain with ease and upkeep is minimal.
- Can be fitted to both Syphon and Direct setups, above or below ground water tanks.
The CWD Manual Option
The Manual Contaminated Water Diverter can be connected to any water tank system preventing all those “gutter nasties” from getting into your water tank and therefore your drinking water. The system can be fitted to any system set up including above and below ground Water Tanks.
When we get the “first flush of water” or have a good dump of rain, you simply open the Manual Diverter Valve, the head of water between the water tank and the Sediment Tank, rushes down the downpipe into the top of the Sediment Tank, rinses the in-line filter and drops all dirt, debris etc into the bottom of the sediment tank, which in turn is then vacuumed out to waste via the Diverter Valve. Once the Sediment Tank is empty, return the Valve to the closed position to allow the clean, debris-free water to go into your water tank.
