I live in Mesa. These figures are from my Jan 2014 bill.
Total water charges including sewer,fees and taxes: $58.02
Total billed gallons: 9000
Cost per gallon of billed water: 0.64 cents per gallon.
Assuming a 4:1 ratio and 100% waste,my cost per RO/DI gallon in Mesa is 3.2 cents. Most LFS charge 10-30 times that for RO/DI,
The value is what you make of it in time,travel, and extra effort.
I paid about $150.00 for a BRS 4-stage system last October.
If you use the low end of 33 cents per gallon for purchased RO/DI, the unit payback point is at 454 gallons.
I use about 25 gallons per week for all our tanks.
If you ignore the approximately 300 gallons for initial setup and cycling of my 110g DT + 30g sump, it will have paid for itself in less than 5 months.
If you count the setup water, it's already paid for itself and my tank has only been cycled for 2 months!
My back already thanks me!
