Historical Developments
Oldest first1992
International water policy produced statements that seeded sustainable urban water management policies
Statements developed in 1992 led to the creation of several policies elevating the importance of water and steering urban water system management towards sustainable development. These provided the policy framing within which supply networks were subsequently planned.
2000
New South Wales Health Centre investigated the public health impacts of domestic grey water reuse
The Australian study found that grey water contains less nitrogen and fewer faecal pathogenic organisms than sewage, and that its organic content decomposes more rapidly. The findings supported the case for grey water reuse as a component of sustainable urban water supply.
Recent Developments
Most recent first2010
United Nations General Assembly formally recognised the human right to water and sanitation
The General Assembly acknowledged that clean drinking water and sanitation are essential to the realisation of all human rights. The recognition reframed water supply provision as a rights obligation rather than a discretionary service, informing how states and utilities approach coverage of unserved populations.
