CARNEGIE (AP) – Some Pittsburgh suburbs hit by flash floods during a brief but intense weekend thunderstorm are blaming overloaded sewers for the mess.

Carnegie Mayor Jack Kobistek says it could take weeks to fix the borough’s sewers, many of which backed up into homes when they were also flooded with storm drainage Saturday evening.

The worst damage was in Carnegie and Scott Township, neighboring municipalities just southwest of the city.

There were widespread reports of basement flooding, though some streets also flooded when storm drains couldn’t handle about 2 inches of rain that fell in a short period of time.

The flooding was the worst in those areas since September 2004, when rains from remnants of Hurricane Ivan flooded much of southwestern Pennsylvania.
