Northampton County's cities and boroughs are sewered, but the slate belt towns, the Bushkill and Plainfield farm country and much of the Lower and Upper Mount Bethel area run on on-lot septic. In Pennsylvania those systems are permitted by a municipal Sewage Enforcement Officer under the Sewage Facilities Act, Act 537, and the rules in 25 Pa. Code Chapters 71 to 73.
Some townships go further. Bethlehem Township's Chapter 201 requires every on-lot system to be inspected and every treatment tank pumped at least once every three years, with the township sending notice about a year ahead.
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 septic areas: Lower Mount Bethel, Upper Mount Bethel, Plainfield, Washington Township, Bushkill, Moore, Lehigh Township, Lower Saucon, Williams and the rural parts of Bethlehem Township.
- Crews run Route 33, Route 611, Route 512, Route 248 and I-78.
- Check your township's own on-lot management ordinance; schedules and fees differ from one municipality to the next.
Common Jobs in Northampton County
- Pumping to meet a township three-year schedule
- Certified inspections for a sale or the first required pumping
- Baffle, riser and lid repairs found during a pump-out
- Drainfield repairs on shallow slate or wet soils
- Holding tank pumping
- Locating tanks on older farmhouses
What Drives Pricing Here
- HomeGuide's published national pump-out range is $300 to $700, based on $0.30 to $0.70 per gallon of tank size.
- HomeGuide lists an inspection at $150 to $450; Bethlehem Township's ordinance requires a certified inspection the first time a tank is pumped under its program.
- Penalties: Bethlehem Township's Chapter 201 sets fines of $300 to $1,000 for violations, with each day a separate offense, so missing a pumping deadline costs more than the pump-out.
- Method: HomeGuide's per-gallon range scaled to your tank, plus township fees. Haul distance to a disposal site and steep slate-belt driveways add local cost.
Permits & Local Rules
- Step 1, SEO permit: under Act 537 (35 P.S. § 750.1 and following) and 25 Pa. Code Chapters 71 to 73, every on-lot system needs a permit from the municipal Sewage Enforcement Officer, including repairs.
- Step 2, township schedule: Bethlehem Township's Chapter 201 (§ 201-10) requires inspection and pumping at least every three years, with notice about one year ahead.
- Step 3, inspector: inspections under that ordinance must be done by an inspector certified by the Pennsylvania Septage Management Association and registered with the township. The ordinance lets the SEO grant a one-time extension of up to two years where a tank shows little buildup, but the total interval can't exceed five years, and holding tanks must be pumped at least once a year.
- Step 4, malfunctions: § 201-12 gives an owner 7 days to apply for a repair permit, 30 days to start work and 60 days to finish after notice.
- Step 5, penalties: § 201-14 sets fines of $300 to $1,000 per violation; ask your own township which ordinance applies.
Soil & Site Conditions
- Slate belt: the Martinsburg Formation slate along the north of the county near Bangor, Pen Argyl and Wind Gap weathers into shallow, stony soils over rock, which limits trench depth.
- Karst: limestone and dolomite of the Lehigh Valley floor south of the slate belt can open sinkholes and move effluent quickly to groundwater.
- USDA NRCS soil survey data rate 78.3% of Northampton County (PA095) as very limited for septic tank absorption fields.
- Census ACS counts about 129,448 housing units, and about 40.7% were built before 1960, so many on-lot systems serve older homes.
- Cold winters and frost make access to buried lids harder in midwinter; risers help.
