The 3W approach: WATER.

Over the past 150 years urban water infrastructure has brought great public health
benefits to billions of people in the industrialised world (and into piped and
sewered communities in developing and transitioning nations). However, the
impact of these public health advancements has not been felt equally around the
world; with millions of urban dwellers living without access to safe and reliable
water, sanitation or drainage services.
The majority of cities in the developing world are currently continuing to struggle
to provide an adequate water supply system to rapidly expanding urban
populations. A lack of reliability in both quality of supply and consistency of supply
decreases community willingness to pay, and therefore the utility’s funding base,
and inversely it increases risks of water borne disease and public health risks.
Additionally, urban water experts now acknowledge the severe economic, social
and environmental costs that have been associated with the current reliance on
centralised, and expensive, infrastructure. Vulnerable communities have been
relocated to make way for large dams. The poorest communities have been out
priced, and continue to lack access to proximate systems due to high water and
sewerage charges.
