Sewer Line Repair in Lopez Island, WA
The pipe between a house in Lopez Island and the public main is the owner’s, and on cast iron it is a run that loses capacity slowly rather than failing suddenly. There are 1,464 occupied homes here, and across all the housing the median build year is 1985 — the best single clue to what the pipe is made of and how it tends to fail.
In short
Where a run changes material partway is the question in Lopez Island, given typical housing of 1985: cast iron close to the building, plastic further out. The two fail differently on a single lateral, which is why the changeover point matters.

What went in the ground around 1985
A lateral laid in Lopez 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
On cast iron the recording should dwell on the bottom of the pipe, where corrosion channels and scale collect. The full picture on cast iron laterals.
Lopez Island is the 64th largest block of laterals we cover in Washington, carrying about 0.1% of the 1,780,641 homes on our WA list, and its housing runs older than 74% of the WA towns we route. Age concentration matters on a lateral: where a whole street went in one season, the failures arrive in one season too.
79% of homes here are owner-occupied — 19 points above the WA figure. That matters more on a lateral than on almost any other pipe in the house: the run from the building to the main is the property owner’s to repair, and a landlord and a resident owner do not find that out at the same speed.
Median household income across Lopez Island ZIP codes is $78,871 — the number to read against a repair that is the owner’s alone.

Before anyone digs in Lopez Island, get the run on camera — and ask what the bottom of the pipe looks like, because scale along the invert reads as a blockage. What the recording should show you.
