- “Greywater may be used for non-potable applications such as crop and landscape irrigation, toilet flushing, cooling, groundwater recharge, vehicle washing, laundry, bathing, ornamental lakes and streams, dust control, street washing, and snow melting, depending on the level of treatment applied.”
- High removal efficiency was obtained for COD (82–87.4%), PO₄³⁻ (85–100%), NO₃⁻ (57–64%), and turbidity (58–89%) using natural filtration media. [[Ref 02 Low-cost_treatment_of_grey_water_and_reuse_for_irrigation_of_home_garden_plants.pdf#page=1&selection=43,102,52,34|Cite]]
- Thermal energy recovery of greywater may allow for household energy savings of up to 40%.
- The energy cost to transport water in centralized water management systems... is estimated to be, on average, four times the energy required for the actual water treatment.
- Pollutants from grey water can produce adverse effects if it accidentally comes in contact by people during WC flushing or spraying during gardening. [[Ref 01 Grey-water-reclamation-for-urban-non-potable-reuse-challenges-and-solutions-a-review.pdf#page=4&selection=341,4,341,32|Cite]]
