Sydney Water has reported an increases interest in waterless urinals and ultra-low flush urinal systems as a way to save water in large buildings and public amenities.

There are three main designs of waterless urinals, each with different requirements for installation and maintenance:
  1. Oil barriers - refillable or replaceable cartridge
  2. Mechanical 
  3. Microbial blocks

There are also various Standards that apply to waterless urinals which are:
  • WaterMark certification
  • Australian Standard 3500.2:2003 for sanitary plumbing and drainage
  • Australian Technical Standard 5200.459:2004

Water Efficiency Labelling and Standards (WELS) and Australian Standard 6400 currently does not apply to waterless urinals.

Factors to consider when specifying and installing waterless urinals
  • look for WaterMark approved models
  • understand all relevant technical standards and Australian Standards
  • ensure current sewer pipes are not made of copper or copper alloy
  • sufficient fall of the sewer pipes to avoid urine pooling and odour, build up of scale and sludge
  • properly ventilated areas
  • sufficient sewer service diagrams
  • regular cleaning regimes are implemented
  • physical barrier between the user and sewer pipes
  • other water-using facilities are upstream of waterless urinals
