Changes

:"The urban water cycle consists of three main engineering paradigms: stormwater and wastewater disposal and water supply. All three paradigms are actually based on a centralised control and pipe transport paradigm (the pipe paradigm). Beder [http://homepagewww.macherinst.com/herinstorg/sbeder/sewage/paradigms.html 1993] explains that the pipe paradigm is popular with authorities because it ensures that water supply and wastewater disposal is a relatively automatic process and is a public rather than individual responsibility. The centralised nature of pipe paradigm also provides significant control, power and revenue to central authorities such as water authorities, local and state governments. The perception of lost power and revenue is a major source of institutional resistance to the use of decentralised technologies such as rainwater tanks.

:"Powerful institutional bodies such as the [[Institution of Engineers]], Australia; and the '''Australian Water Association''' have perpetuated the pipe paradigm. These institutions perpetuate the pipe paradigm through education and practice that is specified in accordance with the paradigm. Beder [http://homepagewww.macherinst.com/herinstorg/sbeder/sewage/paradigms.html 1993] states that this has resulted in the domination of the wastewater disposal and water supply industries by engineers who have discarded the search for better solutions because the consensus is that the pipe paradigm is adequate."<ref>P.J.
