A Water Benefit Certificate (WBC) represents a volume of water that has been sustainably supplied, purified or conserved.
A Water Benefit Certificate represents different volumes for different project types due to the wide range of volumes between small but high-impact community projects like Water Access Sanitation and Hygiene (WASH) and large projects like agricultural interventions or wastewater treatment:
- For volumes up to 40,000 cubic metres per annum (m3 p.a.), 1 m3 = 1 WBC
- For additional volumes greater than 40,000 m3 but less than 1,300,000 m3 p.a., 10 m3 are worth 1 WBC
- For additional volumes greater than 1,300,000 m3 p.a., 100 m3 are worth 1 WBC
