HERVY is a pioneer in the implementation of technology seeking rational water use. HERVY was the first Brazilian company to develop a toilet tank that uses only 6 liters of water per cycle and is the only one with a two-inch siphon — in other words, more efficiency with less water consumption.
In 2007, after three years of research, HERVY introduced into the market the first high performance Brazilian toilet, capable of using only 4.8 liters of water without the need for any water pressure equipment.
These are only some of the results obtained from the ongoing research in our laboratories.
HERVY also participates actively in institutional programs to develop low water consumption products like PBQP-h (http://www.cidades.gov.br/pbqp-h/), having environmental awareness and sensible water use as its main concerns.
