The importance of water and sanitation
"We forget just how fundamental water and sanitation is to human dignity, to human decency, and to aspirations of people across the developing world."

The power of public campaigning
"It's much easier as a government minister  keen to do the right thing  if you have the support of the public behind you."

Engaging with the political process
"Our learning over recent years has convinced us that water and sanitation needs to be a central part of our work to tackle effectively the global poverty that still scars our world."

Accountability
"We want governments to be responsible to their own peoples.

How can we make a difference?
"I think resources and finances matter, but so do people of goodwill, conscience and concern. Those are really the only people who have ever changed the world."

The challenges ahead
"The work that WaterAid is doing and others are doing is even more vital, and even more important, not less in the face of this economic downturn."
