THE MATH

Sewer line replacement cost formula

Total = length × rate × depth × access + permits

PVC installed runs ~$100/ft, cast iron ~$150/ft and clay-pipe repair ~$125/ft. Deep trenching adds 40%. Difficult access adds up to 50%. Permits ~$800.

PRACTICAL EXAMPLE

60 ft of PVC, standard depth, moderate access

Pipe = 60 × $100 × 1 × 1.2 = $7,200. Permits = $800. Total ≈ $8,000.
