Lebanon County leak detection, 24/7
Leak Detection in Lebanon, PA
Lebanon has some of the oldest water pipes in the county, and the winter of 2026 proved it, with most of the authority’s main breaks inside city limits. Four in ten city homes were built before 1940. A local technician finds the leak on your side of the curb stop so you fix it once.
- Row homes, twins and older detached homes across 17042 and 17046
- City of Lebanon Authority service lines traced from curb stop to house
- Written reports for your plumber, landlord, insurer or the authority
Calls answered day and night. Emergency? Shut off your main valve first, then call.
Quick answer
Is a leaking water line at my Lebanon house my problem or the authority’s?
The City of Lebanon Authority splits service lines at the curb stop: the authority side runs from the main to the curb stop, and the property owner side runs from the curb stop to the house. A leak on the owner side is yours to repair, so a pinpointed location keeps the dig small.

Why Lebanon Homes Leak
Lebanon’s housing is old and its water system is old. About 80 percent of city homes were built before 1970, and the authority says many mains and service lines are 75 to 100 years old. Freezing winters and a shrinking, drought stressed supply raise the stakes when a pipe fails.
NeighborhoodScout figures based on Census data show 39.94 percent of Lebanon homes built in 1939 or earlier and another 40.27 percent built from 1940 to 1969. Just under 5 percent date from 2000 or later.
Row houses and attached townhomes make up about 34 percent of homes, and single family detached homes another 32 percent. Duplexes, converted homes and apartments fill out the rest, and about 54 percent of homes are rented.
Census Reporter puts the city at 26,536 people in 4.2 square miles, with 11,685 housing units and a median home value of $156,500. That is a lot of old plumbing packed into a small footprint.
What we find by era
| When the home was built | Typical materials | Common leak points |
|---|---|---|
| 1939 and earlier (40%) | Galvanized supply, cast iron drains, lead or iron service lines possible | Corroded galvanized threads, old service lines, cracked cast iron stacks |
| 1940 to 1969 (40%) | Copper and galvanized supply, cast iron drains | Copper pinholes, joints in walls, leaks under basement floors |
| 1970 to 1999 (15%) | Copper, CPVC, PVC drains | Fittings, water heater connections, slab runs |
| 2000 and newer (5%) | PEX, PVC | Crimp fittings, appliance and outdoor lines |
In 2023 the authority wrote that almost 100 miles of cast iron mains are due for replacement and that it spends about $3 million a year on aging mains and service lines (CoLA column in LebTown).
Old Mains, Winter Breaks and What They Mean for Your Pipes
Lebanon’s unique problem is the age of the pipe in the street. In early 2026 the authority logged 13 main breaks in two months, nearly all inside the city, and in May a 1965 valve blew apart and dumped about 1.7 million gallons. Pressure swings from repairs like these stress old house plumbing too.
LebTown reported that the authority had nine main breaks in January 2026 and four more in February. All but two were in Lebanon city, where the authority has some of its oldest pipe, and frigid weather caused more breaks and leaks than usual.
On May 8, 2026, a leaking valve on a 12 inch main at 12th and Lehman streets turned into a 20 to 25 foot geyser when the top blew off. The valve and main were both installed in 1965, and rusted bolts were the likely cause (LebTown). Crews cut water to 88 homes and found a cracked 4 inch main during a second dig.
Why a street break can become your leak
- Shutoffs and restarts send pressure surges into old service lines and fittings
- Ground disturbed by a nearby dig can shift a rigid old line
- Rust and sediment loosened by flushing can foul valves and toilet fill valves
- A curb stop that has not been turned in decades may not close fully when you need it
If your meter keeps moving or pressure stays low after the street is repaired, have the line checked. The authority fixes its side. The curb stop to the house is on the owner.
The authority is hunting leaks too
CoLA says its leak detection program cut water lost to leaks to one third of what it was. In 2025 it withdrew an average of 6.8 million gallons a day and sold 5.2 million, with the other 1.4 million going to leaks, hydrants, flushing and bulk haulers (LebTown). A 2025 Susquehanna River Basin Commission grant is paying for more detection equipment.
Drought, the Siegrist Reservoir and Why Every Leak Counts
Lebanon’s water comes from the Siegrist Reservoir and Swatara Creek, and 2026 tested both. The county spent much of the year under a drought watch or warning, and the reservoir hit a record winter low. A hidden leak in a Lebanon home wastes water the whole system was asked to save.
The authority’s sources are the Siegrist Dam in Schuylkill County and the Swatara Creek intake in Jonestown (CoLA). Safe yield is 7 million gallons a day against average use of 6.5 million, and a new supply study by Black and Veatch started in 2026 (LebTown).
At the end of January 2026, Siegrist was more than 15 feet below its spillway. In late June the county moved to a drought warning and CoLA asked for 10 to 15 percent voluntary cuts. The county returned to normal status on October 2, 2026 (LebTown).
A toilet leaking 0.25 gallons a minute wastes about 10,800 gallons a month. That is the kind of loss a dye test catches in ten minutes.
Drought also affects the ground. PA DEP lists drought and lowered groundwater, along with leaking water and sewer pipes, among the conditions that can trigger sinkholes. The DCNR notes karst is common where limestone and dolostone underlie southcentral Pennsylvania, and Lebanon sits in the Lebanon Valley, part of the Great Appalachian Valley.
Signs of a Hidden Leak in a Lebanon Home
Lebanon water is inexpensive by Pennsylvania standards, so a leak can run for months before the bill looks alarming. Watch the meter, the basement walls, the sidewalk over the line and any shared wall with a neighbor. Those signs show up long before the money does.
Meter and bill
- Meter moving with every fixture off
- Quarterly bill higher with no change in use
- Hissing at the meter or main valve
- Pressure drop on upper floors
Basement and walls
- Damp front foundation wall where the line enters
- Wet party wall shared with a neighbor
- White mineral crust on block or stone walls
- Warm spot on a basement floor
Sidewalk and yard
- Wet sidewalk joint or curb in dry weather
- Water standing in the curb box
- Sunken soil or a small hole over the line
- Green strip across a lawn in a dry spell
EPA WaterSense says a faucet dripping once a second wastes over 3,000 gallons a year and that 10 percent of homes have leaks wasting 90 gallons or more a day.
Leak Detection Services for Lebanon Properties
Pennsylvania Leak Detection connects Lebanon owners and landlords with local technicians who find service line, slab, wall, sewer and fixture leaks. In a city of old row homes and converted apartments, service line and multi unit work make up a large share of calls.
Water service line leak detection traces the owner side from the curb stop to the basement wall. With thousands of lines of unknown material in the inventory, the technician also notes what the pipe is made of where it enters.
Commercial and multifamily leak detection helps landlords with converted homes and small apartment buildings find which unit or riser is leaking. Hidden wall and ceiling leak detection works through plaster with thermal and moisture tools.
After a cold snap, frozen and burst pipe leak detection finds every crack. For old cast iron and clay, sewer lateral and drain leak detection uses a camera and sonde. And when a pipe gives way at night, emergency leak detection is answered 24/7.
How the Visit Works
Call, get a price, and a local technician comes with acoustic, thermal, pressure and tracer gas equipment. The leak is confirmed at the meter, isolated by section, pinpointed and marked, and you receive a written report.
1
Call
Describe the problem. The price is quoted on the phone.
2
Test
Meter and pressure tests confirm a leak and split the house into sections.
3
Pinpoint
Listening equipment, thermal imaging and tracer gas locate it.
4
Report
The spot is marked and documented for the repair.
What the report covers
- Readings before and after isolation
- Photos and measurements of the leak location
- Whether the leak is on the owner side of the curb stop
- Pipe material where visible, useful for lead line questions
Any excavation needs a PA811 call at least 3 business days ahead.
Service Lines, Lead and High Bills with the City of Lebanon Authority
The City of Lebanon Authority, or CoLA, supplies water to Lebanon city and much of the county. It divides each service line at the curb stop: authority side from the main to the curb stop, owner side from the curb stop to the house.
That split appears in the authority’s lead inventory figures reported by LebTown in June 2026, which counted 2,135 lines of unknown material on the authority side and 6,579 on the owner side. A May 2026 update showed 2,002 and 6,761. CoLA serves about 70,000 people across 12 municipalities (CoLA).
| Section | Responsibility | Notes |
|---|---|---|
| Main in the street | CoLA | Breaks are the authority’s to repair |
| Main to curb stop | CoLA (authority side) | Tracked separately in the lead inventory |
| Curb stop to house | Property owner | Most private service line leaks |
| Sewer lateral in the city | Property owner to the public sewer | CoLA runs sewer collection in the city |
Lead service lines
In November 2024, CoLA mailed letters to 2,300 customers whose lines might contain lead. Its inventory of 22,000 service lines included 165 known lead lines (LebTown). The authority uses lime and a high pH for corrosion control, and asks owners who confirm lead to tell CoLA so replacement can be prioritized.
Handling a high bill
- Do the meter test and toilet dye test.
- Book leak detection and get a written report.
- Repair the leak and keep the invoice.
- Contact CoLA, explain the leak and repair, and ask what options apply.
We did not find a published leak adjustment policy for CoLA, so we cannot promise a credit. As a municipal authority, it is generally outside the PA PUC‘s rate oversight, so questions go to the authority and its board. Our high water bill guide and service line ownership guide cover the details.
What Leak Detection Costs and What a Leak Costs in Lebanon
Leak detection alone runs about $150 to $600 nationally, quoted on the phone. Because Lebanon water is cheap, the real cost of a leak is often damage to a basement or wall, not the bill. Still, water plus city sewer adds roughly $10 per 1,000 gallons.
CoLA held water rates flat for 2026. Its published estimates put annual water bills at $614 for 100,000 gallons and $395 for 48,000 gallons, so each extra 1,000 gallons costs about $4.21 ($219 divided by 52). City sewer rises from $5.30 to $5.98 per 1,000 gallons starting in April 2026.
| Leak flow | Gallons per 30 days | Water at about $4.21 | City sewer at $5.98 | Added per month |
|---|---|---|---|---|
| 0.1 gal/min | 4,320 | $18.19 | $25.83 | about $44 |
| 0.25 gal/min | 10,800 | $45.47 | $64.58 | about $110 |
| 1.5 gal/min | 64,800 | $272.81 | $387.50 | about $660 |
| 3 gal/min | 129,600 | $545.62 | $775.01 | about $1,321 |
Water per 1,000 gallons derived from CoLA’s published annual bill estimates; excludes base charges. Township sewer rates differ. Flow figures from FACTS (30 day month).
In 2023 CoLA said its water rates were about 40 percent of Pennsylvania American Water’s (CoLA). The 2025 rate increase averaged 5 percent (LebTown). For repair costs, This Old House puts an average slab leak repair at about $2,300. See our cost guide.
Lebanon ZIP Codes, Sections and Local Notes
Lebanon is a city and the Lebanon County seat, with ZIP codes 17042 and 17046. It was incorporated as a borough in 1821 and became a city in 1885, so much of its plumbing is layered on very old buildings.
| Area or reference point | Local notes | What to watch |
|---|---|---|
| Downtown and the north side | The Union Canal once ran along the north side (1828 to 1885) | Oldest row homes and commercial buildings |
| 12th and Lehman streets area | Site of the May 2026 valve and main failure | Pressure surges on old service lines |
| North Partridge Street | UGI gas main replacement between Mifflin and Lehman streets, fall 2024 | Coordinate any dig with PA811 |
| Quittapahilla Creek corridor | Creek drains the city westward toward Annville | Damp ground and basements near the creek |
| North Cornwall and nearby townships | Borders the city to the south and west; sends wastewater to CoLA’s plant | Detached homes with longer service lines |
Details come from the Lebanon and Quittapahilla Creek entries, the May 2026 break report and LebTown’s UGI coverage. Most of Lebanon County drains to Swatara Creek and the Susquehanna.
We cover the whole city and Lebanon County, plus Hershey and the rest of the Lancaster, Harrisburg and York region.
Winter in Lebanon: Freeze Season Is Break Season
In Lebanon, cold weather breaks pipes on both sides of the curb. The authority saw more main breaks than usual in the frigid winter of 2026, and the same cold finds weak spots in old house plumbing, especially front walls, rear additions and unheated porches.
Pennsylvania soil freezes about 24 to 42 inches deep (Penn State PHRC). Service lines that run shallow under steps or porches are most exposed.
- Let a tap drip on the coldest nights if a pipe runs on an outside wall
- Close off and insulate crawlspace vents in winter
- Shut and drain outdoor spigots in the fall
- Test your curb stop and main shutoff before winter, not during a burst
Read our frozen pipe guide. If a pipe has split, close the main, then call.
Gas Leak Safety in Lebanon
UGI Utilities supplies natural gas in Lebanon and is replacing older gas mains in the city. If you smell gas, leave first, then call UGI at 800-276-2722 or 911 from outside.
LebTown reported in October 2024 that UGI had replaced more than 50 miles of gas main that year, including North Partridge Street (LebTown). In May 2026 crews had to lift a UGI gas main off the broken water main at 12th and Lehman before repairs could finish. UGI’s safety page lists its emergency line.
Smell gas?
No switches, no phones, no flames inside. Get out, then call from a distance.
After the utility makes it safe, our gas line leak detection service locates customer side leaks.
DIY Checks Before You Call
Watch the meter with everything off for 15 minutes, dye test each toilet, and look at the foundation wall where the service line comes in. These checks cost nothing and narrow the problem fast.
- Turn off all water use and watch the meter for 15 minutes.
- Close the main shutoff. If the meter still moves, suspect the service line.
- Add food coloring to each toilet tank; color in the bowl within 10 minutes means a leak.
- Check the curb box and sidewalk for water in dry weather.

Frequently Asked Questions
Who supplies water in Lebanon, PA?
The City of Lebanon Authority (CoLA). It draws from the Siegrist Reservoir in Schuylkill County and Swatara Creek at Jonestown and serves about 70,000 people across 12 municipalities.
Who is responsible for my service line in Lebanon?
CoLA treats the main to curb stop as the authority side and the curb stop to the house as the property owner side. Leaks on the owner side are the owner’s to repair.
Does Lebanon have lead service lines?
Some. CoLA’s 2024 inventory listed 165 known lead lines out of 22,000, and it mailed 2,300 letters about lines that might contain lead. Thousands of owner side lines are still unknown material.
How can I find out if my line is lead?
Check where the pipe enters your basement, have your water tested at a local lab, or ask a technician to note the material during a visit. If you confirm lead, tell CoLA so it can prioritize replacement.
Why are there so many water main breaks in Lebanon?
Age and cold. CoLA says many mains are 75 to 100 years old, and in January and February 2026 it had 13 breaks, all but two in the city.
Can a main break in the street cause a leak in my house?
It can. Pressure surges and ground disturbance from repairs can open weak spots in old service lines and fittings. If your meter moves after a nearby repair, have it checked.
Does CoLA give leak credits?
We did not find a published leak adjustment policy. Fix the leak, keep the report and invoice, and contact the authority to ask.
How much does a leak add to a Lebanon bill?
Roughly $10 per 1,000 gallons for water plus city sewer in 2026. A running toilet near 0.25 gallons a minute adds about $110 a month.
How much does leak detection cost?
We quote the price on the phone. National guides put leak detection alone at about $150 to $600.
Do you cover the townships around Lebanon?
Yes. We cover all of Lebanon County, including North Cornwall and the other townships around the city.
What do I do if I smell gas in Lebanon?
Leave the building, then call UGI at 800-276-2722 or 911 from outside.
Hearing Water You Cannot See? Call Now.
A rising water bill, a wet basement wall or a soggy strip of lawn will not fix itself. Call any hour and we will help you find the leak, prove it and keep the repair as small as possible.
Answered 24 hours a day, 7 days a week.
