State officials say the water system is back online in the Pine Ridge area.
On Saturday, Governor Kristi Noem announced she was activating 13 soldiers with the South Dakota National Guard to help with the situation.
Now that the water is back on, the troops are headed home.
Flooding is still an issue on the reservation.
