(CNN) -- At least 200 homes in the colony of San Isidro and La Providencia, in the Mexican state of Mexico, remained flooded Sunday because a crack in an area sewage canal caused water to overflow into the city, authorities said.
There were no fatalities reported among the roughly 500 residents in the affected area, but three minors were reported injured, according to the local fire department. One youth was slightly injured when he tried to flee his house, while another two minors were admitted to the hospital with symptoms of hypothermia.
The crack in the wall of the Canal de la Compania is about 30 meters long, staffers at the National Water Commission (Conagua) told state-run news agency Notimex. The crack, located at the 27.5 kilometer marker of Puebla Highway, is allowing the output of about 6,000 cubic meters per second of raw sewage, Notimex said.
The crack was caused by heavy rains overnight, newspaper El Milienio reported.
The first calls about the flooding came about 2 a.m. Sunday, according to the local fire department.
State of Mexico Governor Enrique Pena Nieto was scheduled to tour the area, Notimex reported.
Authorities anticipate that the situation could be controlled by late Sunday, but the highway would likely remain closed until sometime Monday.
