GreyWater Recycling

(GWR)

As a result of population growth, urbanisation, economic growth and climate change, domestic water consumption has i. Therefore, water conservation has become very important. At Chamberlains Aqua Systems Limited (CASL), we offer different innovative water efficiency solutions; one of which is Grey Water Recycling (GWR). GWR allows the conservation and effective reuse of water.
Greywater can be defined as any domestic wastewater produced, excluding black water (i.e. wastewater produced in the toilet). Black water contains very high amount of organic matters in comparison with greywater. The main sources of greywater are the wastewater generated in baths, showers, washing machines, dishwashers and kitchen sinks. Although, many GWR technologies cannot properly deal with the wastewater produced in the last two, therefore wastewater from dishwashers and kitchen sinks are excluded in some definitions of greywater. Proportion of greywater to the whole household wastewater varies depending on household characteristics and water use habits, but generally it is about 40 to 80% of a household’s wastewater.

Benefits:

• Reduction in water use by 50 per cent.

• Reduction in discharged wastewater to the sewerage

• Significant reduction in mains water and sewage bills(up to 50%)

• Short payback period compared to other sustainable technologies

• Can be combined with rainwater harvesting

• Tax savings

• No chemicals required
