Funding calculation when payback is two or more years

Rebate = (litre of water saved per day*) x ($0.40)

* Average daily water use over a one-year period)

Example:

A 152-unit multi-residential building with 228 occupants replaced the toilets, showerheads and aerators with water efficient models. The project's capital cost was $60,000 with a payback of more than 2 years. Over the next 12-month, water consumption decreased by 2,500,000 litres, averaging out to about 6,849 litres per day.

Rebate received = $2,740 (6,849 litres saved per day x $0.40)

Calculations to determine funding:

• Average water savings per day: 6,849 litres ((8,000,000 - 5,500,000) ÷ 365 days)
• 12 months of water consumption using water billing data:
  • Prior to upgrade: 8,000 cubic metres (8,000,000 litres)
  • After upgrade: 5,500 cubic metres (5,500,000 litres)
• Payback period: (project capital costs) ÷ (total water savings for year x municipal water billing rate)
