Local Help in Northampton County, PA

Northampton County's sewers are run by its cities, boroughs and township authorities rather than by the county. Bethlehem, Easton, Nazareth, Bangor and the townships around them each set their own connection rules, but they share one principle: the owner pays for the private lateral.

Bethlehem's sewer ordinance spells it out. Article 921.02(m) says the owner of any improved property shall maintain and repair the building drain and sanitary sewer lateral at his own expense, and shall remove trees, tree roots and other obstructions. That rule dates to 1972, and many of the laterals it covers are older still.

Northampton County Service Details

What providers in this area actually see: coverage, common jobs, local pricing factors, and rules worth knowing.

Service Area Notes

  • Coverage across the county: Bethlehem, Easton, Nazareth, Bangor, Hellertown, Bath, Wind Gap, Palmer Township, Forks Township and Wilson.
  • Crews run US 22, I-78, Route 33 and Route 191 between the Lehigh Valley cities and the slate belt.
  • Tell us your municipality when booking; permits come from the city, borough or township, not the county.

Common Jobs in Northampton County

  • Root cutting and repair in clay tile laterals under older city streets
  • Camera inspections before buying a pre-war rowhouse or twin
  • Cast iron drain replacement inside older basements
  • Lateral replacement with a new cleanout at the curb
  • Testing an existing lateral before reconnecting it to new plumbing

What Drives Pricing Here

  • HomeGuide's published national average for replacing a residential sewer line is $6,000, and most jobs run $2,000 to $10,000.
  • HomeGuide lists a camera inspection at $125 to $500. On a lateral running under a sidewalk and city street, that inspection decides whether lining or digging is the cheaper route.
  • Trenchless pricing per linear foot, per HomeGuide: $60 to $200 for pipe bursting and $90 to $250 for cured-in-place lining.
  • Local fees are small next to the work. The City of Bethlehem fee schedule lists a residential sanitary sewer permit at $50, plus the $4.50 state training fee.
  • Method: national ranges from HomeGuide, adjusted for local factors such as depth, rowhouse access, street cuts and municipal permits.

Permits & Local Rules

  • Step 1, responsibility: under Bethlehem Codified Ordinance Article 921.02(m), the owner maintains and repairs the building drain and lateral.
  • Step 2, permit: the City of Bethlehem's Article 1702 fee schedule sets a one- or two-family sanitary sewer permit (new, replacement or repair) at $50, and adds $4.50 to every permit for the state-imposed training fee.
  • Step 3, testing: Article 921 lets an existing lateral connect to new building sewers only after the City Plumbing Inspector finds, through examination and testing, that it conforms; the permit holder supplies the equipment and labor.
  • Step 4, re-inspection: after the first re-inspection, the City of Bethlehem lists a $75 fee for each additional visit, so have the trench ready before calling.
  • Outside Bethlehem, check with your borough or township; each adopts its own sewer ordinance and fees.

Pipe Stock & Soil Notes

  • Census ACS data put Northampton County's housing stock at 129,448 units with a median year built of 1971, and 40.7% were built before 1960.
  • Older homes in the neighborhoods near downtown Bethlehem, College Hill in Easton and the boroughs along the Lehigh River often still have clay tile laterals and cast iron drains.
  • Tree roots from mature street trees along older blocks find the joints in clay pipe; Bethlehem's ordinance names them specifically.
  • Frost reaches shallow pipe in hard winters, and freeze and thaw cycles can move joints in short laterals near the house.
  • Slate and shale bedrock near Bangor and Pen Argyl can make deep trenches slower and more expensive to dig. Rowhouses and twins with shared walls add another wrinkle: a lateral may run under a neighbor's yard or join another line before the street, so confirm the route on camera before anyone digs.

Side view of a home's sewer line. The house drain leaves the basement, passes a capped cleanout beside the house, and runs as the sewer lateral under the yard, property line, sidewalk and street to a tap on the city main. Bars beneath show the homeowner owning the lateral from the house to the property line, the city owning the main, and the stretch from the property line to the tap varying by city.
The homeowner is responsible for the lateral on private property; some cities extend that to the tap on the city main, so check the local utility's rule for the stretch under the street.

Emergency Response Expectations

If sewage is backing up, stop water use and call your municipal sewer office to check the main. Requests here go to independent local plumbers.
