This calculation is based on replacing 5 high flow showerheads (19L/min) with WELS 3 star showerheads (9L/min) and demonstrates the savings associated with reduced water and sewer charges and the payback period for the cost of the upgrade.
Calculation: litres/minute x 5 mins x 10 showers/day x 5 days x 50 weeks
discharge factor 95%
|Total water &
|Payback period = ($500/$614) x 12 months
For a facility with 10 showers, this represents an annual saving of 1,250 kilolitres and over $6,000. The savings increase even further, when you factor in reduced hot water energy costs.
