COST SAVINGS ANALYSIS
For Kitchen Restaurants ( based on LA commercial rate )
_____________________________________________________________
Water savings =1/2 gallon per handwash based on 5persons in a restaurant kitchen
_______________________________________________________________
5 persons x 2 times an hour x 10 hours a day x 30 days x 1/2 gallons saved
= 1500 gallons
Assumptions ( All Figures on this page may Vary with Different Cities and States and Different Habits of Usage)
A. Water Rate = $4 + $4 Sewerage = $8 per 1000 gallons
B. Gas Rate = $1.6 per therm (Average Rate )
Gas required = 10 therms to heat 1000 gallons of water x $16
= $16 per 1000 gallons
= $10 per 1000 gallons (assume 66% hot water)
Cost Savings based on 10 persons @ 10 hours a day
__________________________________________________
1. Water Savings = 1500 gallons x ($4 Water rate + $4 Sewerage cost) = $12
2. Gas Savings = 1500 gallons x $10 (Assume 65% HOT WATER) = $15
Total Cost Savings = $27
= $324 per year per sink
3. Other Cost Savings:
______________________
Soap/ detergents, Faucet Costs, Heater, Boiler, Sewerage pipes
Engineer's Time for Maintenance of Heater, Faucets, Sewage pipe = $10

= $300 per year ( based on $695 outright purchase price)
Impact on ENVIRONMENT
1500 GALLONS PER SINK = 18,000 GALLONS PER YEAR
