Re-using grey-water that would otherwise be sent down your DWV systems for treatment is the mother of all water savings.

Isn't saving 30,000 Gallons (113,562 Liters) of water per year worth considering the change?

Energy-saving calculations:

  • City of Vancouver Water Utility rate is $1.827 / 625 Gallons (2,365.8 Litres)
  • City of Vancouver Sewage rate is $1.243 / 2,831.6 Litres
  • Yearly water savings = $87.96
  • Yearly sewage savings = $49.85
  • Yearly total savings = $137.84
  • 25 Year savings = $3446.00 & 2,839,050 Litres of water
  • SPR = ~$500.00 CDN
  • ROI =  85.49% (HOLY CRAP!!)
