A small fire broke out at 1:23 a.m. Saturday in a holding tank at the Sand Island Wastewater Treatment Plant, Fire Capt. Terry Seelig said.
The tank contained fertilizer pellets.
Firefighters sprayed down the smoldering pellets and extinguished the fire at 5:15 a.m.
“There was no damage to the tank that would require replacement or repair at this time,” said Seelig.
There were no injuries.
