If your Washington Suburban Sanitary Commission bill is much higher than usual, you can blame the polar vortex.
WSSC officials said the winter snow and ice delayed meter readers, resulting in a billing cycle as much as one month longer than usual. Some customers could see a bill as much as 30 percent higher than expected. The number of days a bill covers is in the upper right portion of the bill.
Most residents are billed every three months, while larger commercial customers are billed about every 30 days, according to the WSSC.
Customers with questions can reach WSSC at 301-206-4001.
