Water conservation has been one of the major research drivers over the past 10-15 years. It has affected w.c. design, drainage system sizing and vent design due to lower entrained airflows. It has impacted upon appliance design, from the development of the pressure-assisted flush and subsequent improvements to gravity operation, so ably discussed in PME (Nov. 2003), to the design of appliances such as washing machines and dishwashers. Water conservation has been promoted as "the right thing to do."
