Septic tank pumping is the process of removing accumulated solids, sludge, and scum from the septic tank before they reach a level that blocks the outlet baffle, overloads the drainfield, or forces raw sewage back into the home. Ontario homeowners often discover their tanks are overdue in spring, when snowmelt raises water tables, saturates drainfields, and pushes a stressed system into failure faster than any other season.

Septic system winter damage refers to the structural and functional harm that Ontario’s freeze-thaw cycles, frost heave, and spring snowmelt inflict on tanks, risers, distribution boxes, and drainfield pipes over the cold season.
