Ask anyone - the government, the volunteers or the survivors what they need the most and you get a simple answer: "Water."
Drinking water supplies are running low and the authorities are very concerned that if it isn't addressed soon it could lead to diseases breaking out, which would only exacerbate an already difficult situation.
At Kathmandu's Bir hospital, the shiny new trauma centre - a brand new gift from neighbour India - is overflowing.
Every bed is filled and the road outside is being used as a makeshift emergency room, with patients lying on mattresses and blankets. Aid workers mingle with the hospital medical staff, assessing the situation.
"There's an urgent need for crutches, stretchers and other medical supplies especially in the outlying districts," says Sarah Blin, country director of Handicap International.
"Cargo planes are coming in, there is material coming in including medical tents and other supplies."
But most of the aid material is coming into the capital and the areas just around it.
"There's an urgent need to get it out into the remote areas, where conditions are far worse," says Ms Blin.
At the other end of the hospital, behind the old wing, soldiers wearing face masks perform a grim task. A pick-up truck carrying a body has just arrived. It is covered in dirt.
"We found this body in the Darbar Square under a destroyed temple," says one of the soldiers.
They carry it into the hospital and place it along with a few other bodies outside the morgue, in the open. There's no space inside.
A few people shuffle past them, faces covered with handkerchiefs because of the stench, trying to identify the victims.
It is distressing sight. But every now and then the rescue workers have reason to hope.
"While we were digging out this body, we found a man trapped inside who we've pulled out," says the soldier. "We are taking an oxygen cylinder out to him now. He's going to survive."
