São Paulo university saves 360.000 litres (95,000 gallons) of water each day

In São Paulo, Brazil, water is scarce and expensive. In 2007, this university installed a Jets™ system which paid for itself in 15 months. How could the pay-back period be so short?

Expensive water

The answer lies in São Paulo's water prices. High bills for water were a burden on the university: with daily water costs of USD $1,800 for the 420,000 litres (110,000 gal.) of water used for toilet flushing each day, the university spent close to USD $50,000 a month on flushing its 720 toilets!

Cutting water consumption with Jets™

After installing a Jets™ vacuum sanitary system, the amount of water used for flushing was reduced to just 60,000 litres (16,000 gal.) a day, and the water cost fell to a mere USD $320 a day.
