Sewer Line Repair in Fenwick Island, DE
Whoever owns a property in Fenwick Island owns the lateral under it, out to the main. On iron, what that ownership eventually costs is decided at the bottom of the pipe. There are 315 occupied homes here, and across all the housing the median build year is 1987 — the best single clue to what the pipe is made of and how it tends to fail.
In short
Cast iron on the house side with early PVC beyond it is the usual arrangement under Fenwick Island properties, whose housing typically dates from 1987. Iron corrodes along the bottom of the pipe, so a survey looks at the invert rather than at the seams.

What went in the ground around 1987
A lateral laid in Fenwick Island in that period is most likely cast iron on the house side and early PVC beyond it. Cast iron corrodes along the bottom of the pipe, so capacity is lost gradually rather than suddenly. More on cast iron laterals.
What a camera survey should settle here
