Water Efficient Toilets and Urinals

Dual Flush Valve Toilets

Dual flush toilets can provide up to 30% water savings, if used correctly. This option encourages the user to choose between 1.6gpf (solids) or 1.1gpf (liquids). For flush valve toilets, the dual flush mechanism is part of the flush valve and can be easily installed on existing flush valve toilets. If the toilet is outdated, the toilet should be reviewed by a local toilet manufacturer or plumber to ensure that the new low flow option will work with the existing toilet trap way and bowl design. Although dual flush toilets are not considered to be new technology, adequate signage at the toilet should be provided to educate the user on the flush options. This will ensure that the low flow options are used more often which will ultimately provide increased water savings.

High Efficiency Toilets (HET)

Compared to the traditional 1.6gpf, new high efficiency toilets are designed to reduce water consumption by 20% having a single flush option using a maximum 1.28gpf.

Waterless Urinals

Waterless urinals function without any water or flushing mechanism. A replaceable cartridge, containing a unique sealant liquid, is used in lieu of a traditional drain. The sealant liquid acts as an airtight barrier, preventing odours from mitigating into the room, and is lighter than urine so it floats on top of the liquid beneath it. The sealant liquid remains in the cartridge while the urine passes through the drain. Cleaning a waterless urinal is the same process as a traditional urinal. However, the cartridge needs to be replaced approximately 3-4 times per year.

Ultra Low Consumption Urinals

An alternative to waterless urinals, this type of urinal contains an internal flow regulator that limits the water usage to only 0.125gpf. Using this urinal achieves up to 80% water savings when comparing to the traditional 1gpf.
