"This request and full payment for testing must be received at least 14 days prior to the scheduled closing of a Sale or Refinance."
That single sentence sits buried on a policies and procedures page for the North Huntingdon Township Municipal Authority, the entity everyone in the township just calls NHTMA. Most sellers never see it until their closing date is already circled on a calendar. By then, the math has stopped being flexible.
Here is the scenario that plays out more often than it should. A homeowner lists their house, gets an accepted offer within a couple of weeks, and starts planning around a 30 to 45 day close. The home inspection happens. The appraisal gets scheduled. Somewhere in that window, either the seller's agent or the title company mentions that NHTMA requires a dye test and lateral inspection before closing, and that the request has to go in with full payment at least 14 days ahead of the date. If nobody flagged it on day one, the seller is now racing a clock that started the moment they should have made a phone call, not the moment they remembered to.
This isn't a fee tacked on for revenue. It's a compliance gate, and understanding why NHTMA runs it the way it does tells you something real about the pressure the township's sewer system is under right now, and why the timing rule is stricter than it might feel like it needs to be.
What the Test Actually Checks For
A dye test is exactly what it sounds like. A technician introduces colored dye into a home's plumbing, usually through a drain or downspout, and watches the sanitary sewer system downstream to see whether that dye shows up somewhere it shouldn't. The lateral inspection covers the pipe that connects a house to the main sewer line, checking for the same problem from a different angle: cracks, faulty joints, or a connection that lets rainwater and groundwater into a pipe that was only ever designed to carry wastewater.
That unwanted water has a name in the utility world: inflow and infiltration, or I&I. Inflow is stormwater entering through things like a downspout tied into a sanitary line instead of draining onto the lawn. Infiltration is groundwater seeping in through a cracked pipe or a bad joint. Neither belongs in a sanitary sewer, and Pennsylvania's Department of Environmental Protection requires municipalities to address it directly. Under Act 537, local governments have to adopt a corrective action plan to control sewer system overloading, and removing stormwater from sanitary lines is part of that mandate. NHTMA's dye test program is how the Authority satisfies that requirement one property at a time, using the point of sale as the moment it can actually check.
Why NHTMA Is Watching This So Closely Right Now
Point-of-sale testing exists in a lot of Pennsylvania municipalities. What makes it worth paying attention to in North Huntingdon specifically is the scale of what the Authority is dealing with at the same time.
NHTMA is a participant in a regional Consent Order and Agreement with ALCOSAN, the Allegheny County Sanitary Authority, which everyone from North Huntingdon eventually flows into. That agreement exists because ALCOSAN found it could not affordably convey, store, and treat every drop its member municipalities were sending its way, and inflow and infiltration is a large part of why. As part of that process, NHTMA has run its own I&I reduction study to identify which parts of the township are contributing the most excess flow, both from public infrastructure and from private connections on individual properties.
The Authority is also, right now, mid construction on a $46.1 million upgrade to its wastewater treatment facility at the Youghiogheny plant. Its board approved an $11.4 million operating budget for fiscal year 2027 along with an $8.8 million five-year capital improvement plan at its April 2026 meeting, and that plan includes projects like the replacement of the Kee Road Pump Station, which conveys sewage northwest into Trafford Borough before it reaches ALCOSAN, and the fifth phase of a sanitary sewer replacement project in the Markvue Manor area.
Every gallon of rainwater that sneaks into that system through an illegal downspout connection or a broken cleanout cap is capacity NHTMA has to pay to pump and treat, on top of the capacity it's already spending millions to rebuild. A point-of-sale dye test is one of the few moments the Authority gets real leverage to catch a private-side problem before it becomes someone else's headache after the deed changes hands. That's the actual reason the 14-day rule exists, and it's also why it isn't likely to get looser anytime soon.
One Township, Two Different Sewer Rules
Not every property in North Huntingdon connects to NHTMA's system. Large portions of the township still run on individual on-lot septic systems, and those homes fall under an entirely separate set of rules that has nothing to do with dye tests.
| Homes on NHTMA public sewer | Homes on on-lot septic (Township Chapter 432) | |
|---|---|---|
| Who enforces it | NHTMA | Township Sewage Enforcement Officer |
| Required before a sale | Dye test and lateral inspection | No specific pre-sale test mandated by the chapter, though township inspections occur on a set cycle |
| How often it repeats | Test result valid 5 years from the original test date | Inspection required every 3 years, tank pump out required every 3 years |
| Rough cost | $260 as of 2026, confirm current rate with NHTMA | Full septic evaluations for real estate purposes typically run $300 to $600 through a certified inspector |
The practical takeaway is that a seller's first question shouldn't be "what does the test cost," it should be "which system is my house even on." A quick call to NHTMA will confirm connection status in minutes, and it's the fastest way to find out which clock actually applies to a given closing.
The Timing Risk Nobody Budgets For
Even for homes squarely on NHTMA sewer, the 14-day window is a floor, not a target. Payment has to be received before the Authority will schedule an appointment, and scheduling itself takes time once the request lands. A seller who waits until the week their offer is accepted to think about this test is often already inside the danger zone, especially if the accepted offer carries a 30-day close.
There's a shortcut worth checking before assuming a new test is even necessary. Because results are valid for five years from the original test date, a home that changed hands or was refinanced within the last five years may already have a current dye test on file. It's worth asking NHTMA directly whether a property has existing results before paying for a new one.
A short list of what actually protects a closing date:
- Confirm sewer connection type with NHTMA the day a home is listed, not the day an offer comes in
- Ask whether a prior dye test on the property is still within its 5-year validity window
- Submit the request and payment as early as possible rather than waiting for the 14-day minimum to become the plan
- If the home is on septic instead, check the last pump-out and inspection dates against the township's 3-year cycle
A Few Questions Sellers Ask
Does this apply to refinances too, or just sales? Both. NHTMA's policy language covers "the scheduled closing of a Sale or Refinance," so a homeowner refinancing without selling still needs to plan around the same 14-day requirement.
What happens if the test finds a problem? If a dye test turns up an illegal stormwater connection or the lateral inspection reveals a defect, the fix has to happen before the Authority will sign off, which is exactly the scenario a seller wants to discover in week one of a listing rather than three days before closing.
How do I find out which system my home is on if I've never had to think about it? NHTMA can confirm this directly, and it's a five minute phone call that removes all the guesswork before a listing goes live.
None of this is complicated once someone tells you about it early. The problem is that most sellers only hear about the dye test from a title company or a closing coordinator, at the exact moment when there's the least room left to react.
