Jordan's second-largest refugee camp for Syrian refugees now has a water well and a new school.

The projects are part of long-term investments in the still-growing Syrian refugee population as the conflict drags on.

A new remedial school aims to support 1,300 students. The well, Azraq's first, will cut water costs in half by avoiding having to truck water into the camp.

Officials from the U.N., U.S. and Jordan inaugurated the projects Wednesday.

U.S. Ambassador Alice Wells called the school a "small down payment" for preparing Syrians to eventually return home and rebuild their country.

More than 4 million Syrians have fled their country since the conflict began in 2011.

Jordan hosts about 630,000 refugees, including about 100,000 who live in formal camps. Azraq has 21,000 residents.
