Rainwater overwhelmed the sewer system in tiny Saco on Sunday afternoon.
The town received 6.91 inches of rain over the weekend, according to the National Weather Service.
The deluge overwhelmed the pumps that usually move sewage from lift stations into two lagoons outside town, said Shirlee Whitaker, Saco town clerk.
"Our pumps were working, but there was just too much rain for our pumps to keep up," she said. "I didn’t think anyone knew how much water we were going to get."
The town has a separate system for stormwater. A series of grates takes water off the gravel streets of Saco and into a neighboring irrigated hay field.
To make sure sewage didn't get into homes, Saco residents were asked to regulate their water usage until the storm waters subsided and the excess water could be pumped out.
With the help of some local farmers, ranchers and a few of the companies in town, the water in both systems had been moved out of town, and everything was back to normal by midmorning Monday.
Saco is a town of fewer than 200 residents in Phillips County.
