School Water Efficiency Index Calculator

Pre-requisites for the successful completion of the e-service

Before you start, please gather the following info:

• Total water consumption in the last 12 months from the same year **
• Total population of students, teachers and employees

** If you do have water consumption data less than 12 months, you can take an average figure and multiple it by 12 months.

 Example

• Total water consumption of 9 months = 18,000m³
• 18, 000m³ divide by 9 months = 2,000 m³
• Multiple 2,000 m³ by 12 months to get total 12 months’ water consumption of 24,000m³.
