Mixed Faucets

While a standard sink faucet delivers 17-18 liters of water per minute, mixed faucets deliver 7.5 to 8 liters per minute, thus saving water.

Problem:

What is the annual water savings for a family of three, each using a mixed faucet for at least 5 minutes per day?

Answer:

The family currently uses a total of 15 minutes of water, which translates to 270 liters per day from 15 x 18 liters, or 97,200 liters per year. If the family uses a mixed faucet; It uses 120 liters of water per day from 15 x 8 liters, or 43,200 liters per year.

The family saves 54 tons of water by using a mixed tap...

What can be done with the 54 tons of water saved?

A dishwasher can be run 4,500 times.
A washing machine can be run 306 times.
A 5-minute shower can be taken 900 times.
A bathtub can be taken 350 times.
