Upper St. Clair dye test and sewer lateral inspection
Selling in Upper St. Clair takes two things before closing: a dye test and an inspection of the sanitary sewer lateral. The Township puts both on the seller.
What Upper St. Clair requires
Last checked November 2026- Required for
- Sale or transfer of any property in the Township. The seller is responsible.
- What's required
- A dye test (Ordinance 1787, adopted 1998) plus a sanitary sewer lateral inspection (required since January 1, 2018)
- Also required when
- Improvements need both a Township building permit and an Allegheny County plumbing permit. This triggers the lateral inspection.
- Timing
- The Township recommends doing both early in the selling process, in case you don't pass and need repairs.
What the inspection covers
- The dye test confirms that no surface water or groundwater connections run into the sanitary sewer.
- The lateral inspection checks the condition of the private sewer pipe from your house to the public main.
If the test fails
Failed connections and lateral defects have to be repaired before the sale can close. Start early so a repair doesn't push back your closing date.
