Waste not, want not: in the world's arid regions, even sewage water cannot be thrown away
Article Abstract:
Population centers in arid regions, such as Namibia's capital city of Windhoek, face daunting water supply challenges. Windhoek confronted a dramatic water supply crisis in the late 1960s, when population increases had severely compromised the city's reservoir's and aquifers. A water reclamation plant that was inaugurated in 1968 produces enough potable water to supply close to a quarter of the Windhoek's needs. Improvements planned for the program are detailed.

Leaking away: more than one billion gallons of water flow through New York City ever day, and hardly a drop is wasted
Article Abstract:
New York City chose a water conversation project instead of another pumping station in the early 1990s, when it faced an impending water shortage caused by increased population and drought. Citizens were enticed to install low-flush toilets and low-pressure shower heads with a $295 million rebate program, resulting in a savings of nearly 90 million gallons of water per day. Water-efficiency surveys informed homeowners of areas where water could be conserved.
