REPORTER: For the past two months

almost constant rain has caused massive flooding

in Lima and northern Peru.

Nine-year-old [INAUDIBLE] home was swept away

in the swelling river.

TRANSLATOR: At first, the river overflowed.

I was afraid that my brothers and sisters

were going to drown.

REPORTER: [INAUDIBLE], her mom, and siblings

are living here in shelters assembled just last week.

About 400 families are struggling

to survive in this temporary refugee camp on higher ground.

A muddy pond below is their main source of water.

We learned that some people have been without clean drinking

water for up to three weeks.

TRANSLATOR: My mom walked to the road.

She asked a lot of people to give us water to drink.

We were so thirsty.

After a few days she came back with only one small bottle.

REPORTER: Meanwhile, the rains fell.

Mudslides and flooding made life miserable.

[INAUDIBLE] said she prayed.

TRANSLATOR: I asked God to keep the river

from overflowing again.

And God listened to me.

My brother, Manuel, and I were really thirsty.

And we asked God to send water.

REPORTER: Just one day after her prayer for water to drink,

CBN came to her community.

We set up water purifiers, which cleaned

hundreds of gallons of pond water in just a few hours.

A grateful Rocio and her brother satisfied their thirst.

TRANSLATOR: God heard me.

And he send me water to drink.

REPORTER: But the need for fresh water continues across Peru.

And CBN is trying to reach as many people as possible

in the coming weeks.
