Standard urinal flush mechanisms use in excess of 2ℓ
per flush. Not only do you not have to touch the flush
mechanism, but the low flush urinals use 1ℓ per flush,
saving water and limiting the spread of germs.
The taps on the wash handbasins and sinks are fitted
with flow inhibitors, which keep the water flowing at a
slow but usable 5ℓ and 9ℓ per minute, respectively.
The Zenprop development is targeting potable water
consumption of no more than 0.065m 3 /m 2 /yr. This is
a 93% reduction on the Cape Town average. Water
consumption will be monitored by water meters and
through the building management system (BMS).

Information from the BMS is used for reporting to the
building operations manager. The target is compared
to the Cape Town and Australian averages and National

best performance.
WATER SUPPLY
Only a small portion of the building’s water supply
needs to be potable. Major water demands like
irrigation and toilet and urinal flushing can be met with
recycled grey water.
All major potable and recycled water consumption is
metered and devices are connected to the monitoring
