Designing plumbing systems
Larry Konopacz, manager of training and education at the Little Red Schoolhouse reviewed some interesting stats regarding water: People living in residential areas in North America and Japan use about 92 gallons of water per day compared to people living in Europe — they use 52 gallons per day. In sub-Sahara Africa people use only 2.6 to 5.2 gallons of water per day. Experts have estimated that water consumption rates are rising at twice the rate of population growth. About 2.5% of the water on earth is fresh water, which is limited and fixed, and is being used by more and more people.
