Water Recycling
Grey Water Recycling
Grey water recycling is the use of water from baths, showers, sinks, etc to be re-used for toilet flushing, garden use and anything apart from human consumption.
The mildly polluted wastewater from shower/bath, washbasin and washing machine (GREYWATER) is utilised as an internal household water resource after undergoing the appropriate treatment.
In private sector housing, savings of 45 Litres of drinking and wastewater per person / per day are possible, and these can rise to above 60 litres per guest / per day in hotels.
The reuse of already used water reduces the costs of water supply and wastewater treatment. The greywater recycling plant pays for itself within a few years. The double use of valuable water conserves the ground-water resources and reduces the wastewater load.
Rainwater Harvesting
Collection and use of rainwater would appear the obvious way forward in reducing the use of mains water and surface water run off.
This system collects rainwater from the roof via gutters and down pipes through a gravity type filter into an underground tank. This initial filtration takes out larger particles from the rainwater.
The oxygenated water then flows into the tank through an inlet, where a second purification takes place. There are various other components inside the tank necessary to guarantee good water quality.
