Cambridge is a city in Washington County, Idaho. The Census Bureau puts its internal point at 44.571748, -116.678101 and its land area at 0.48 square miles. Septic permitting and record keeping happen at the county level, not the city level, which is why every figure below is attributed to the county and linked back to the county page it came from.

Our collection for Washington County, Idaho is small, at 2,282 septic records. Treat it as a starting point for a Cambridge property rather than a search that settles the question. The county is genuinely mixed: 2,295 of 4,673 classified parcels are on septic and the rest are sewered. Which side of that line a Cambridge address falls on is worth establishing before anything else. We have not found a published online records portal for this county, which means the file is requested from the county directly rather than searched.
