Lori Casa, spokeswoman for Waste Management, said collection services have been delayed in various service areas, including parts of Western Pennsylvania. Sewickley contracts with Waste Management.
"In some cases it's due to severe weather conditions or the holiday," Casa said.
Landfills in Washington County closed because of the snow, causing everything to run behind schedule, according to borough officials.
Any trash that hasn't been picked up, will be hauled soon and the schedule will be as normal again on Monday, Jan. 7, officials said.
