Third Pipe Wastewater Recycling
Water can be sourced from greywater, treated wastewater or drainage water for non-drinking uses in and around the home. This is generally referred to as a ‘third pipe’ system as it requires an additional pipeline to the house (separate from the existing drinking water and wastewater pipes) to supply the water.
The water could be used for external uses such as garden watering and car washing as well as some domestic internal uses such as toilet flushing.
