The Marshall Township Sewer Test That Depends on Which Authority Owns Your Street

A seller in Marshall Township schedules a closing date, then calls the number she has for the township's sanitary authority to ask about point-of-sale paperwork for her sale. The person on the phone asks for her address, pauses, and tells her that particular street isn't served by that authority at all. It belongs to a different one, with its own application, its own fee, and its own processing calendar. Her closing date doesn't move. Her runway to get the paperwork done just did.

This happens more than most sellers expect, because Marshall Township is not served by one sanitary authority. It's served by three.

The Test Isn't Checking What Most People Assume

If you've heard about point-of-sale sewer requirements in nearby townships, you might picture an inspector checking whether old clay pipe is cracked or a lateral line is letting groundwater seep in. That's not what Marshall Township's process does.

The Point of Sale Dye Test Application, administered by the Marshall Township Municipal Sanitary Authority (MTMSA), must be submitted at least 14 working days before closing, and the residential fee runs $175. The test itself, laid out in the township's own ordinance and adopted into Pine Township's code for the shared Marshall Service Area, is a visual inspection and dye test checking whether interior sumps and drains, or exterior downspouts and area drains, are illegally tied into the sanitary sewer system. The ordinance calls these the "interior test" and "exterior test." A home can have flawless pipe underground and still fail this test if a previous owner solved a drainage problem years ago by routing a downspout into a sanitary cleanout instead of daylighting it into the yard.

That distinction matters for pricing risk. A failed lateral test points to a repair bill tied to the pipe itself. A failed dye test points to a plumbing correction, often smaller in scope.

One Township, Three Landlords for Your Sewer Line

Here's the part that catches sellers off guard. Marshall Township's own Sanitary Authority page states plainly that public sanitary sewer service across the township comes from three separate providers, not one. The majority of the township is served by MTMSA. The area east of I-79 and south of North Allegheny's Marshall Campus falls under the McCandless Township Sanitary Authority. Two pockets near the township's western border are served by the Economy Borough Municipal Authority.

Same township, same school district, same "Marshall Township" line on the listing sheet. Three different offices decide how your closing paperwork moves.

Here's what that split actually looks like in practice.

The township even maintains a Sanitary Sewer Service Area map and a list of roads serviced by MTMSA specifically, because the boundary lines between the three service areas don't follow anything a buyer or seller would intuit from a street address alone.

Where Sellers Lose Days They Don't Have

A seller can spend the first several days figuring out which authority serves the property.

The lien letter process adds a second fork in the road. For properties served by MTMSA, sewage lien letters go through Jordan Tax Service, Inc. for a $35 fee. A seller working from general instructions rather than a confirmed service area can end up requesting the wrong document from the wrong office twice before getting it right.

None of this is unusual for Pennsylvania, where sewer oversight is handled at the municipal level rather than through a single statewide system. What's specific to Marshall Township is that "municipal level" doesn't mean one office. It means three, and the only way to know which one applies is to check the address against the service map before the listing goes live, not after an offer is signed.

Why This Isn't Getting Looser Any Time Soon

Sewer infrastructure across this part of the North Hills is under active, funded attention right now. The North Hills Council of Governments opened bidding on its 2026-2027 Sanitary Sewer Rehabilitation Project, with sealed bids due by 11:00 a.m. on August 27, 2026. The member and associate municipalities named in that bid notice include Marshall, Franklin Park, Pine, McCandless, and Fox Chapel, alongside more than a dozen other North Hills communities and the Marshall Township Municipal Sanitary Authority itself.

A coordinated, multi-municipality rehabilitation contract at this scale signals that these authorities are actively assessing and maintaining their systems, not scaling back oversight. Point-of-sale requirements built to protect the integrity of a shared sewer system tend to track with how much attention that system is getting. Right now, across this corridor, the answer is a lot.

That matters for timing. In February 2026, Franklin Park, another North Allegheny School District community, had a median 28 days on market against Allegheny County's broader median of 68 days, with homes selling close to full asking price. Homes in this school district have a track record of moving quickly. Confirming the right authority early matters more here than in a slower market.

Before You List in Marshall Township

1. Confirm which of the three authorities serves your specific address using the township's Sanitary Sewer Service Area map, before you assume MTMSA is your contact.
2. Submit the Point of Sale Dye Test application at least 14 working days ahead of your target closing date, and budget $175 for the residential fee if MTMSA serves your address.
3. If your property falls under MTMSA, request your sewage lien letter through Jordan Tax Service separately from the township's own municipal lien letter.
4. Walk your property before listing and check whether any downspout, sump pump discharge, or area drain was ever routed into the sanitary line. That is precisely what the interior and exterior dye tests are designed to catch.
5. If your home has never connected to public sewer and a tap-in is part of the conversation, know that the minimum tapping fee starts at $3,441.

A Few Direct Questions

Does every home in Marshall Township need this test before closing? Check directly with the authority serving the property before listing.

What if my home is on a private septic system instead of public sewer? The Point of Sale Dye Test described here applies to properties connected to sanitary sewer through MTMSA, McCandless Township Sanitary Authority, or Economy Borough Municipal Authority. Septic properties fall under different municipal considerations, and confirming those directly with the township before listing avoids surprises later.

Sewer paperwork rarely makes anyone's list of favorite parts of a home sale, but in a township split three ways between sanitary authorities, it's the kind of detail that separates a closing that goes smoothly from one that stalls in the final two weeks. Knowing which authority governs your specific street before your home goes live gives you the runway to handle it on your terms.
