We use footprint methodologies to quantify the water–energy nexus in WWTPs.
- •
A new indicator “gray water footprint reduction” is proposed.
- •
The energy intensity in most WWTPs is 0.4–0.5 kWh/m3 in China.
- •
6.78 m3 gray water footprint is reduced when 1 m3 domestic sewage is treated.
- •
0.28 kg CO2 are produced when electricity is used to treat 1 m3 domestic sewage.
