Water Main Break on Linglestown Road Leaves Susquehanna Township Under a Boil Water Advisory

A weekend main break in Dauphin County dropped water pressure across two townships and forced more than a dozen streets onto bottled or boiled water. Here's what happened and how homeowners should check their own plumbing before the all clear.

What happened on Linglestown Road

Veolia crews found a leak on Linglestown Road in Susquehanna Township early Saturday morning, September 12. Locating and isolating the break dropped water pressure across a wide stretch of the township, which is standard procedure but also the trigger for everything that followed. By the time crews finished repairs early Sunday, around 3 a.m., the physical leak was fixed, but the water system itself still needed to clear a health check before anyone could call it over.

The advisory reaches well past the break site itself. Laurelwood Drive is on the list, and so are the cluster of Laurel-named courts and circles nearby: Laurel Point, Mountain Laurel, and Laurel Den. A few streets over, Fargreen Road, Saybrook Lane, Terrace Drive, and Enterline Road are included too. Rounding it out are partial stretches of Continental Drive, Melbourne Drive, Rosewall Court, Forest Hills Drive, and the section of Linglestown Road closest to the leak. Residents outside that footprint in Susquehanna Township, and in neighboring Lower Paxton Township, also saw a temporary pressure drop, though their water was not placed under a boil order.

Why the advisory outlasts the leak

This is the part that trips people up every time a main breaks. Once repairs are done and water starts running clear, it looks like the emergency is over. It isn't, at least not yet. A drop in system pressure, even a brief one, creates a window where groundwater or contaminants near the pipe joint can get pulled into the line instead of clean water pushing out. That is a plumbing and hydraulics problem, not a visible dirt problem, so a boil order stays in place until water samples come back clean, regardless of how the water looks coming out of the tap.

Discoloration is a separate, more cosmetic issue. Veolia has told affected customers to expect it and to flush cold taps until the water runs clear, which is normal after a break disturbs sediment that has settled in the pipes over years. It is unrelated to whether the water is safe to drink without boiling, which is why both instructions get issued together and neither one replaces the other.

What to do at home right now

If your address is on the affected list, treat every tap as a boil-water tap for drinking, cooking, brushing teeth, and making ice until Veolia announces the advisory is lifted. That includes water going into a coffee maker or a pet's bowl. A standard pitcher or refrigerator filter does not remove bacteria, so filtered water still needs to be boiled during an active advisory.

Once the all clear comes, the work isn't quite finished. Automatic ice makers and water coolers should be emptied and run through a cleaning cycle before use, and any water heater set below 113 degrees should be drained and refilled, since lower temperatures don't reliably kill bacteria that may have entered the tank during the pressure drop. Homes with whole-house filtration or water softeners should also run those systems through a regeneration or backwash cycle rather than assuming they filtered out the problem automatically.

The bigger picture for Harrisburg-area plumbing

Main breaks like this one are becoming a familiar story across both Pennsylvania and New Jersey this year, and the pattern is consistent: aging pipe, a sudden pressure event, and a boil order that outlasts the actual repair by a day or more. For homeowners, the practical lesson is less about this specific street list and more about knowing the drill before it applies to your own block, because these events tend to arrive with little warning.

It's also a good prompt to check your own service line and home plumbing, especially if your house is older or sits near a main that has failed before. A sudden pressure swing can loosen sediment, stress old joints, or expose a slow leak that was masked by normal water pressure. If you noticed unusual pressure, discoloration that hasn't cleared, or reduced flow after this event, that is worth a professional look rather than a wait-and-see approach.

6 Things to Do During (and After) a Boil Water Advisory

Whether it's this Dauphin County break or the next one closer to home, the checklist for a boil water advisory doesn't change much. Here's the order to work through it.

1. Boil or use bottled water for anything you'll ingest: Drinking, cooking, brushing teeth, making ice, and pet bowls all count. A rolling boil for one minute is the standard guidance utilities use.
2. Don't trust a pitcher filter to fix it: Standard carbon filters reduce taste and some chemicals, but they are not rated to remove bacteria. Filtered water still needs to be boiled during the advisory.
3. Flush cold taps for discoloration, separately from boiling: Running cold water for a few minutes clears sediment stirred up by the break. It's a cosmetic step and doesn't substitute for the safety hold.
4. Empty and sanitize ice makers once the advisory lifts: Ice made during the advisory should be discarded, and the machine should run a cleaning cycle before making ice you'll actually use.
5. Drain water heaters set below 113 degrees: Lower tank temperatures don't reliably kill bacteria that may have entered during the pressure drop, so those units should be flushed after the all clear.
6. Wait for the official lift, not just clear-looking water: Clear water and safe water are two different things after a pressure event. Only lab results confirm it's safe, so wait for Veolia's actual notice.

Frequently asked questions

Why does a boil water advisory stay in place after the leak is already fixed?

Repairing the pipe stops the leak, but it doesn't prove the water inside the system is free of contamination. Utilities keep the advisory active until lab samples confirm the water meets safety standards, which typically takes a day or two after repairs finish.

My water looks clear again. Is it safe to drink?

Not until the advisory is officially lifted. Clarity is about sediment, not bacteria, so clear-looking water can still be under an active boil order.

Does this affect my home's plumbing, or just the water itself?

Usually just the water supply, but a pressure drop can also stress old service lines, joints, and fixtures. If you noticed banging pipes, reduced flow, or a leak start up around the time of the break, it's worth having it checked rather than assuming it's unrelated.

What should I do with my water heater and ice maker after the advisory lifts?

Drain and refill any water heater set below 113 degrees, and run ice makers or water coolers through a cleaning cycle before using ice or water from them again. Both can hold contaminated water even after the tap itself is clear.
