- Mitigation title
- Water efficiency measures
- Description
-
This relies on increased water usage efficiency in households as a method to reduce the volume of wastewater generated by single households, for example reducing water use from 120 L/person/day to 80 L/person/day. When scaled up and coupled with waste water treatment works that have phosphate strippers, this method has the potential to reduce additional volumes of wastewater requiring treatment and outfall phosphate loads.
Like all schemes, these reductions must be managed and kept in perpetuity and updates to the system to allow more water usage with new owners needs to be controlled.
