Frequently Asked Questions

Find the answers to some of the most commonly asked questions about water recycling. 

Rainwater harvesting or recycling (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation.

Greywater, Grey Water, or gray water recycling (GWR) – depending on where in the world you are, is the collection, filtration and storage of waste water specifically from wash hand basins, showers, baths, ablutions, swimming pool back-wash, and condensate, for reuse in non-potable distribution such as WC flushing, Irrigation and Wash Down.

These are common terms in the industry. Basically, it simply refers to the way the water is distributed to the point of use.

Direct – the stored water is pumped directly from the storage tank to the point of use. mains water is topped-up into the main storage tank. This means that you have better pressure and higher flow rates. However, if you have a pump failure of power cut you lose your non-potable supply i.e. no toilet flushing!

InDirect – the water is pumped to a cistern, normally a header tank. The mains water is topped up into this tank with a mechanical ball valve. The water is distributed to the point of use from the cistern by gravity. This means that even in the event of pump failure or power cuts, you still have a supply of water. however, the pressure is not suitable for some high pressure WC cisterns, and not suitable for irrigation.

Absolutely! Our grey water systems collect water from the wash hand basins, showers and baths, for reuse in WC flushing. When you combine our system with a sewage treatment plant (STP) you are reducing the volume of water going into the system, and increasing biological density (more bacteria per litre of waste), and lowering the level of surfactants, this actually helps the treatment plant clarify and treat your waste more rapidly.

Of course, having a septic tank can be costly, and time consuming, with regular costs for tank emptying. By diverting the less contaminated waste of wash hand basins showers and baths, treating it, then using it for WC flushing, you are reducing the volume water entering the septic tank by the total volume of WC flushing.

This can reducing you emptying frequency by as much as 40%.
