Halcrow provides services in all aspects of urban water supply
By 2030 it is projected that 5 billion people, 60% of the world’s population, will live in urban areas – an increase of 1.6 billion people over and above today’s urban dwellers.
In 2015, the target date for hitting the Millenium Development Goals, one of which includes halving the number of people without access to safe drinking water, there will still be 850 million people in the world without access to safe water, even if this goal is hit.
Billions of people in urban environments in the developing world, especially the poorest, are unconnected to a municipal water supply and many of these rely on water vendors. In Dar-es-Salaam, for example, fewer than 30% of households are connected to a water delivery system. The poorest people play as much as 10 times more than richer households for water, and often receive poorer quality water.
Many cities lose large quantities of water through leaks in their water distribution systems where 30-40% of the water supply can be lost due to leakage. In cities such as Delhi, Dhaka and Mexico City, about 40% of the water pumped into the system leaks out of corroded pipes or is taken illegally.
Even in the developed world the investment in urban water supply is often insufficient – deterioration of water infrastructure is such that a multi-billion dollar backlog of repair and replacement is gradually building up.
