Septic in Horse Shoe, NC

Last updated: Mar 21, 2026

Hi neighbor—welcome to Horse Shoe, where the French Broad winds through green hills and quiet cul-de-sacs, and a reliable septic system quietly holds our daily comfort together. If you're new to the area or simply want straightforward guidance, you've found a helpful resource. I've spent years helping local families here, so you'll get practical, down-to-earth advice you can trust.

Is septic common in Horse Shoe? Should I expect septic if I own or buy a home?

Yes. In Horse Shoe, most homes rely on private septic systems rather than city sewer lines. The area's rural character and the way our land is laid out mean extending centralized sewer service to every property isn't always feasible or cost-effective. If you own or are buying here, expect to encounter a septic tank and a drainage field as part of the home's core infrastructure. Property disclosures and records should include tank size, type (conventional, mound, etc.), last pumping date, and any inspection notes. If you don't see those records, ask for them—the information helps you plan maintenance and budget for any needed upkeep.

Why homes typically use septic systems in Horse Shoe

This isn't an oversight—it's a practical fit. Our hills, soil conditions, and historical development patterns mean many lots don't have easy access to municipal sewers, and extending lines up a hillside can be expensive and disruptive. A properly sized septic system lets a home treat wastewater on-site, using the natural soils to help filter and decompose waste. It's a cost-effective, self-contained solution that works well with the space and landscape many Horse Shoe properties offer.

High-level explanation (why septic exists here)

  • Rural housing patterns: many properties were built before large-scale sewer expansion, or on parcels where a sewer main isn't nearby.
  • Soil and groundwater considerations: the local soils are often well-suited to on-site treatment when properly designed and maintained, helping protect groundwater and streams.
  • Cost and practicality: private septic systems avoid the cost and coordination required to run sewer mains to remote or hillside homes.
  • Regulatory framework: local health and environmental guidelines are designed to ensure proper siting, design, and maintenance so systems remain safe and effective.

Practical notes for homeowners

  • Regular pumping every 3-5 years is a good starting point, more often for high-usage households.
  • Watch for signs of trouble: slow drains, gurgling sounds, odors, or damp spots over the drain field.
  • Protect the drain field: avoid heavy vehicles or construction over the system; plant grasses (not trees) above the field; avoid chemical drain cleaners.
  • When buying: secure pumping and inspection history, determine tank size and type, and confirm last service date.

This neighborhood-centered approach helps keep Horse Shoe healthy, comfortable, and trouble-free—so you can focus on enjoying the view and the sense of community.

Where Septic Systems Are Common in Horse Shoe

Common locations by terrain and service boundaries

  • Unsewered hillside parcels: many Horse Shoe homes sit on slopes where sewer lines aren't feasible to extend, so a septic system handles wastewater on-site.
  • Valley and lower-elevation parcels outside sewer districts: homes on flatter ground often rely on septic because municipal service hasn't been brought in.
  • Older homes on mid-size lots (roughly 0.5–2 acres): when homes were built before sewer expansion, a gravity septic system was the standard design.
  • Newer developments that aren't yet connected: even as growth occurs, some subdivisions remain on private septic until sewer service is planned or funded.

Why septic is common here

  • Rural development pattern: Horse Shoe has many residential pockets spread out from centralized services, making on-site treatment the practical option.
  • Cost and feasibility: extending sewer mains across hilly terrain and private lots is expensive and logistically challenging, so septic systems are a more affordable, readily available alternative.
  • Local geology and soil variety: soil type and depth to groundwater in this region influence system choices. Where soils drain well, conventional septic fields work; where soils are restrictive, engineered designs are used.

Soil, slope, and groundwater considerations in Horse Shoe

  • Soil types vary: some areas have deep, well-drained soils suitable for standard drain fields; others have clay layers or shallow bedrock that restrict infiltration.
  • Slope and groundwater depth matter: gentle to moderate slopes can support gravity-fed drain fields, while steep areas or high groundwater may require alternatives like mound systems or sand filters.
  • Regulations guide design: design standards and setbacks are established by the North Carolina Onsite Wastewater Program. Check with the NC Department of Environmental Quality for official requirements.
  • Soil information resources: the USDA NRCS Web Soil Survey helps you understand your property's soil type and suitability for septic systems. https://websoilsurvey.nrcs.usda.gov/

Common system designs you'll encounter in Horse Shoe

  • Conventional gravity septic system: typical for well-drained soils with a clear path from the tank to the drain field.
  • Mound systems: used on shallow bedrock, restrictive soils, or high groundwater; these elevate the drain field to improve infiltration.
  • Sand filtration or other engineered fields: applied when soils have limited permeability or when space constraints exist.
  • Aerobic treatment units (ATUs) and other advanced systems: found in properties with challenging soils or where higher treatment performance is desired; these often require professional maintenance and monitoring.
  • Note: always verify what type is installed on a home by requesting the installation permit and as-built drawings from the local health department or a licensed installer.

Quick reference for homeowners

  • Identify and locate: know where your septic tank lid and drain field are, and confirm setbacks before any digging or landscaping work.
  • Maintain with purpose: a regular pumping and inspection schedule helps prevent failures and protects nearby wells and streams.
  • Protect the field: limit heavy equipment and concrete or parking over the drain field, plant only shallow-rooted vegetation, and avoid irrigation spray directly onto the field.
  • Be mindful of waste: avoid flushing large amounts of grease, filters, wipes, solvents, or chemicals that can disrupt beneficial bacteria.
  • When buying a home: ask for the current septic permit, recent pumping records, and the service history; this can reveal pending maintenance or potential issues.

Steps to plan and maintain (quick guide)

  1. Check the installation permit and as-built drawings with the local health department or licensed installer.
  2. Schedule a professional inspection if you're purchasing a home or notice signs of trouble (gurgling sounds, slow drains, standing water over the drain field).
  3. Pump the tank every 3–5 years as recommended by the local pro, adjusting frequency for household size and usage.
  4. Follow maintenance basics and safety tips (see official guidance from EPA and NC DEQ). https://www.epa.gov/septic and https://deq.nc.gov/about/divisions/engineering-nature-conservation/onsite-wastewater-program

Septic vs Sewer: What Homeowners in Horse Shoe Should Know

How septic systems differ from municipal sewer

  • Septic system: on-site treatment—your home's wastewater goes to a private tank and drainfield. Maintenance and replacements are your responsibility.
  • Municipal sewer: wastewater is collected by a city/county system and treated off-site. You pay a monthly sewer bill; the system is owned and maintained by the municipality.

Key implications for Horse Shoe homeowners:

  • Control and costs: septic means more control over maintenance timing but potential large bills for pumping or failure, while sewer provides predictable monthly fees but depends on the utility's infrastructure.
  • Availability: not every lot in Horse Shoe has access to municipal sewer yet; some neighborhoods may connect as service expands.

How a septic system works in Horse Shoe homes

A typical on-site system includes:

  • A septic tank that holds solids and light scum.
  • An underground drainfield where liquid effluent is dispersed and treated by soil.
  • A passive or minimal-mechanism system, relying on soil to filter and degrade waste.

Maintenance basics:

  • Regular pumping removes solids that otherwise clog the drainfield.
  • Soil conditions, water use, and landscape factors influence performance.
  • A failing drainfield can cause backups, odors, and expensive repairs.

When to consider sewer service

Consider connecting to municipal sewer if:

  • Your property is in an area slated for sewer expansion or you're near an available line.
  • Your septic system is old, poorly draining, repeatedly failing, or costly to repair.
  • Soil or groundwater conditions make on-site treatment unreliable.

Typical triggers:

  • Structural drainfield problems (wet spots, slow drains, gurgling plumbing).
  • High annual pumping or frequent repairs without lasting improvement.
  • Plan to sell or refinance, where a failing septic could complicate the process.

Maintenance and cost considerations

  • Pumping frequency: most septic tanks are pumped every 3–5 years, depending on usage and tank size.
  • Pumping and inspection costs: roughly $300–$800 per pump; inspections are often bundled with pumping.
  • Drainfield replacement: a major expense, commonly $10,000–$30,000 or more, depending on size and soil conditions.
  • Sewer connection costs: one-time hookup fees plus monthly sewer bills; total can vary widely by project scope, distance to the line, and permit requirements.

Practical tips for Horse Shoe homeowners:

  • Use water and household chemicals moderately to protect beneficial bacteria in the tank.
  • Avoid flushing solids or non-dispersible items, grease, or harsh chemicals.
  • Keep a records folder of all septic service, maintenance, and inspections.

Signs your septic or sewer needs attention

  • Slow draining, gurgling sounds, or sewage odors near drains or the drainfield.
  • Standing water or unusually green, lush patches over the drainfield.
  • Frequent backups despite pumping and maintenance.
  • Unexpected increases in monthly sewer charges or notices from the utility about rate changes.

Step-by-step quick actions if you notice issues:

  1. Stop flushing non-water items and minimize water use.
  2. Schedule a septic inspection or pumping with a licensed provider.
  3. Check whether sewer service is available or planned for your location.
  4. Consult the local health department or utility for guidance on permits and timelines.

Typical Septic System Types in Horse Shoe

Conventional gravity septic systems

  • How they work: A single or multi-compartment septic tank receives wastewater; effluent flows by gravity to a soil absorption field (drainfield) with perforated laterals buried in trenches.
  • Typical use in Horse Shoe: Common where soils are moderately permeable and the seasonal water table is deep enough.
  • Pros: Simple, relatively low cost, straightforward maintenance.
  • Cons: Requires adequate soil depth and drainage; poorly suited to areas with shallow bedrock or high water tables.
  • Maintenance: Have the tank pumped every 3–5 years (or per local professional guidance), avoid flushing harsh chemicals, and spread out water use to prevent overload.
  • Official guidance: NC DEQ Onsite Wastewater Program and EPA septic basics provide foundational info. See and https://www.epa.gov/septic'>https://www.epa.gov/septic.

Chamber systems (replacement for gravel trenches)

  • How they work: Instead of traditional gravel-filled trenches, modular plastic chambers create wider, rainwater–capable beds for effluent absorption.
  • Typical use: Suitable where space is limited or where refined drainage is desired in rocky or compacted soils.
  • Pros: Lightweight, easier to install, can offer improved infiltration in some soils.
  • Cons: Still requires adequate soil conditions and drainage; capacity is tied to field area.
  • Maintenance: Regular pumping and polite monitoring of surface conditions; avoid heavy machinery over the field.
  • Guidance: See EPA and NC DEQ resources for chamber system considerations. https://www.epa.gov/septic and https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program'>https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program

Mound systems

  • How they work: A raised "mound" built above the natural soil using sand fill and a controlled distribution field when native soil is too shallow or has poor drainage.
  • When used in Horse Shoe: Common on properties with a shallow groundwater table, rocky subsoil, or restrictive layers.
  • Pros: Enables safer effluent treatment where conventional trenches won't perform.
  • Cons: Higher upfront cost; more complex maintenance and monitoring.
  • Maintenance: Regular inspection, pump maintenance, and ensuring the dosing system is functioning correctly.
  • Official references: DEQ guidance and case studies for mound designs. https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program'>https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program

At-grade bed systems and trench systems

  • How they work: Similar to conventional systems but designed for slopes or restrictive soils; at-grade beds are built closer to grade with carefully engineered distribution.
  • Pros: Adaptable to uneven terrain; can improve infiltration in marginal soils.
  • Cons: Still soil-dependent; vulnerable to compaction from heavy use near the field.
  • Maintenance: Keep heavy traffic off fields; schedule regular inspections and pump-outs.
  • Resources: EPA and NC DEQ provide design considerations for non-standard beds. https://www.epa.gov/septic and https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program'>https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program

Pressure distribution systems

  • How they work: A pump or dosing chamber distributes effluent under pressure to evenly irrigate the drainfield, improving performance on slowly permeable soils.
  • Pros: More uniform moisture distribution; can boost field reliability in marginal soils.
  • Cons: Requires power, regular pump maintenance, and soft-start controls.
  • Maintenance: Test the pump regularly, keep the dosing chamber clean, and avoid salts or chemicals that corrode components.
  • Local context: Many Horse Shoe properties with variable soils benefit from pressure distribution when gravity flow is insufficient.
  • Guidance: DEQ and EPA resources outline design and maintenance standards. https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program'>https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program and https://www.epa.gov/septic

Aerobic treatment units (ATU) and compact systems

  • How they work: Pre-treat wastewater with aerobic bacteria, producing a higher quality effluent before it reaches the drainfield.
  • Pros: Effective in poor soils or where space is limited; can handle higher strength wastewater.
  • Cons: Requires electricity, tank monitoring, and annual service; higher ongoing costs.
  • Maintenance: Regular servicing by a licensed installer, routine filter changes, and annual inspection.
  • Resources: EPA septic system pages describe how ATUs fit into onsite wastewater, and NC DEQ outlines licensing and maintenance expectations. https://www.epa.gov/septic and https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program'>https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program

Sand filter systems

  • How they work: An above-ground or below-grade sand filtration bed treats effluent before it reaches the drainfield, often used in soils with limited absorption.
  • Pros: Robust treatment in challenging soils; can extend system life in marginal sites.
  • Cons: More components to maintain; higher installation cost.
  • Maintenance: Regular backwashing (if applicable), keep surface free of debris, and follow local service schedules.
  • References: DEQ guidance on supplementary treatment types and long-term performance. https://deq.nc.gov

Drip irrigation / subsurface drip systems

  • How they work: Treated effluent is applied via small emitters under the landscape, reducing groundwater and surface exposure risk.
  • Pros: Water-efficient, can enable septic use on steeper lots or where drainfields are limited.
  • Cons: Specialized design and maintenance; typically more common in larger rural landscapes.
  • Guidance: EPA and state programs discuss drip in certain residential scenarios. https://www.epa.gov/septic

Shared or cluster systems

  • How they work: A single treatment system serves multiple homes, common in small developments or neighborhoods.
  • Pros: Can lower per-home cost and improve management when planned well.
  • Cons: Requires cooperation, shared maintenance, and clear legal agreements.
  • Maintenance: appoint a single responsible party for operation and maintenance; ensure regular inspections and budget for pumping.
  • Resources: Local environmental health offices can provide guidance on permitted shared systems in Henderson/Horse Shoe areas. https://www.hendersoncountync.gov/health

What to consider when planning in Horse Shoe

  • Soil and slope: Slope stability and soil percolation affect system type choice.
  • Water usage: High water use can overwhelm marginal soils; plan for long-term effluent management.
  • Local regulations: Work with the Henderson County Environmental Health office for permits, setbacks, and code-compliant designs. https://www.hendersoncountync.gov/health
  • Regular maintenance: No matter the system, routine pumping, inspections, and prompt repairs protect your investment and groundwater.

If you're evaluating options for a specific property in Horse Shoe, start with a soil test, then consult with a licensed onsite wastewater contractor and your county health department for the best-fit system type and maintenance plan. Official resources: EPA septic basics (https://www.epa.gov/septic) and NC DEQ Onsite Wastewater Program (https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program'>https://deq.nc.gov/about/divisions/health-service-regulation/onsite-wastewater-program).

Common Septic Issues in Horse Shoe

High water table and soil conditions in Horse Shoe

  • Horse Shoe's mountain foothill soils often include clay-rich layers with limited percolation and, in many lots, a shallow groundwater table. After heavy rains, the ground can stay saturated, pushing effluent toward the surface or backing up in the tank.
  • Signs to watch: soggy areas above the drainfield, persistent odors near the system, and unusually lush patches of grass over the drain area.
  • Why it's common here: seasonal heavy rainfall combined with soil limits can stress systems not designed for high water conditions or shallow drainfields. When a system is installed without soils suited to these conditions, failures happen sooner.
  • What to do: have soils professionally evaluated; consider a system designed for high water conditions (e.g., mound or enhanced drainfield) if your lot has poor drainage or a high water table.

Drainfield failures and surfacing effluent

  • Signs: standing water on or above the drainfield, sewage odors in the yard, damp or muddy patches, backups in the home.
  • Local factors: insufficient drainfield area for the lot, repeated high-water-use (bulk laundry, long showers) leading to overload, and occasional root intrusion or soil compaction from landscape work.
  • Preventive measures: limit daily water input, stagger high-water activities, use water-saving fixtures, and avoid driving or heavy equipment over the drainfield to prevent soil compaction.

Tree roots and landscaping near the system

  • Trees and large shrubs with aggressive roots can invade the tank and buried pipes, causing cracks, blockages, or misalignment.
  • In older Horse Shoe properties, roots may be closer to the system than expected, particularly in rocky or shallow soils where roots spread horizontally in search of moisture.
  • Management steps: keep trees back from the drainfield by a recommended setback, use shallow-root ground cover away from the field, and discuss root barriers with a septic professional if trees are nearby.

Maintenance and pumping schedule

  1. Identify tank size and occupancy; typical residential tanks range from 1,000–1,500 gallons.
  2. Schedule routine inspections every 1–2 years; pumping generally every 3–5 years, depending on usage, tank age, and whether an effluent filter or baffles are present.
  3. Have a pro inspect inlet and outlet baffles and any filters during service.
  4. Maintain thorough maintenance records and keep a map of the system location to avoid damage during landscaping.
  5. Use water-efficient fixtures and distribute high-water-use tasks (laundry, dishwashing) across the week.
  6. Limit garbage disposals and avoid pouring fats, oils, greases, solvents, pesticides, or medicines down the drain to reduce solids and chemical load.

Common household practices that cause problems

  • Fats, oils, and greases accumulate in the tank and drainfield; flushable wipes, cotton swabs, feminine products, and diapers create solids that shorten the system's life.
  • Household chemicals and cleaners can kill beneficial bacteria essential for breakdown; limit harsh chemicals and use septic-safe products.
  • Excessive use of cleaners and detergents can disrupt the natural biology of the tank.
  • Best practices: minimize solids entering the system, flush only wastewater and toilet paper, and use septic-safe products to protect the system's biology.
  • Freeze-thaw cycles and wet springs can move soil and affect drainage; prolonged wet periods keep fields saturated and inflates the risk of effluent surfacing.
  • Seasonal landscaping or construction activity can compact soil and reduce percolation, worsening performance.
  • Preparation: plan maintenance before wet seasons and after heavy rainfall, and consult a local septic pro for site-specific guidance.

Septic Inspection, Permits & Local Oversight

Permits required in Horse Shoe, NC

  • Any new onsite wastewater system, substantial repair, or significant modification requires an official permit from the local health department (Henderson County Environmental Health) with oversight by the NC Department of Environmental Quality Onsite Wastewater Program.
  • A NC-licensed onsite wastewater designer must prepare the design and site evaluation, showing lot layout, soils, setbacks, and the proposed system type.
  • You'll pay permit and inspection fees as part of the process; costs vary by project scope and system type.
  • Keep in mind setbacks and lot-specific constraints (streams, wells, property lines, and structures) are built into the permit review.

The permit process: steps to get your septic permit

  1. Hire a NC-licensed onsite wastewater designer to produce a compliant site evaluation and system design.
  2. Gather required documents: property plat or survey, well location (if applicable), site plan, and the designer's report.
  3. Submit the permit package to Henderson County Environmental Health and pay the review/permit fees.
  4. The county reviews the plan for code compliance; you may be asked to revise plans if issues arise.
  5. Once approved, begin installation under permit; schedule inspections at key milestones and complete an as-built inspection for final approval.

Inspection milestones you should expect

  • Pre-installation review: the designer's site evaluation and design are used to inform the county's plan checks.
  • During installation: inspections verify tank placement, baffle integrity, pump or gravity distribution, field layout, access, and setbacks.
  • Final installation inspection: ensures proper backfill, cover, and system operation; as-built drawings and record drawings are submitted.
  • Reinspection if corrections are needed: the inspector will outline required fixes and a follow-up inspection will be scheduled.

Local oversight: codes, compliance, and long-term care

  • State framework: NC DEQ Onsite Wastewater Program sets the overarching design and performance standards for all systems.
  • Local enforcement: Henderson County Environmental Health administers permits, conducts inspections, and enforces ongoing compliance; violations may require remediation and re-inspection.
  • Maintenance expectations: most systems need regular pumping and maintenance by a licensed provider; aerobic or advanced systems may have additional annual maintenance or reporting requirements.
  • Property boundaries and setbacks: expect rules about minimum distances from wells, streams, property lines, and structures; verify exact distances in your local permit documents.
  • Post-installation records: keep your final permit, as-built drawing, and maintenance records in a safe place for future property transactions or inspections.

Real estate considerations and disclosures

  • If you're buying or selling a home in Horse Shoe, a septic status review or disclosure may be requested as part of the real estate process; verify with your agent and the local health department what records should be available at closing.

Septic Maintenance for Homes in Horse Shoe

Horse Shoe-specific considerations

  • Groundwater and soils: Horse Shoe sits near the Blue Ridge foothills with clay and shallow bedrock in places. In wet seasons or after heavy rain, the water table can rise and drainage may slow, increasing the risk of a saturated drain field. Plan maintenance around seasonal patterns and be prepared for longer recovery times after storms.
  • Proximity to water and wells: Many homes here rely on wells. NC rules emphasize adequate separation between septic systems and wells or surface water to protect drinking water. Confirm setbacks and compliance with your local health department or the NC DEQ On-site Wastewater Program.
  • Root intrusion and vegetation: Trees and shrubs with aggressive roots can threaten drain fields. Horse Shoe yards often feature mature trees; keep root zones clear and limit heavy foot or vehicle traffic over the drain field to reduce compaction.
  • Slopes and erosion: Sloped lots can channel runoff toward the drain field. Install turf or shallow-root ground cover and avoid placing a drainage ditch or sprinkler system directly over the field.
  • Seasonal usage patterns: Vacation homes or seasonal occupancy can create uneven loading. If you're away part of the year, consider how long the standing water in the tank may be, and plan pumping accordingly.

Key maintenance milestones

  • Pumping interval: Most households with a 1,000-gallon tank pump every 3–5 years, but Horse Shoe's high rainfall, well usage, and family size can push this sooner. Use the tank size, the number of occupants, and solids buildup as your guide. Have a licensed septic contractor confirm the schedule.
  • Annual professional inspection: Hire a licensed inspector to check baffles, the tank for cracks, pumps, and the distribution system. Mound or pressure-dosed fields may require more frequent checks if soils are marginal.
  • Drainage system check: Inspect the distribution box, piping, and effluent filters (if installed). Clean or replace filters as recommended by the contractor to prevent solids from clogging the drain field.
  • Tank mapping: Keep a current map of where the tank, lid access, and drain field sit on your property. This helps avoid accidental damage during landscaping or renovations.

Drainfield care and landscaping

  • Protect the field: Do not park cars or heavy equipment on the drain field. Avoid similar weight-bearing use, which can compact soils and damage laterals.
  • Plant wisely: Use shallow-rooted grasses or ground cover over the drain field. Avoid trees with deep or invasive roots nearby.
  • Irrigation and fertilizers: Don't irrigate directly over the drain field, and avoid applying fertilizer within 10 feet of the field. Excess irrigation or lawn runoff can overwhelm the system.
  • Surface indicators: If you notice soggy soil, standing water, or lush green grass above the drain field, call a septic professional promptly.

Water use and household habits

  • Conserve water: Fix leaks promptly; install water-saving fixtures; spread out laundry and dishwasher loads to avoid peak loading.
  • Avoid chemical drain cleaners: They can harm beneficial bacteria in the septic tank and disrupt system balance. Use septic-safe products or consult a professional.
  • Garbage disposals: Use sparingly. They add solids to the tank and can shorten pumping intervals.

Signs of trouble and what to do

  • Slow drains, gurgling, or sewage smells inside or outside the home.
  • Wet, spongy, or unusually lush areas over the drain field.
  • Backups or toilets that won't drain properly.
  • If you observe any of these, reduce water use immediately and contact a licensed septic contractor or the local health department for guidance.

What to ask your local professional

  • Is the soil suitable for conventional septic or do I need an alternative design (e.g., mound or pressure distribution) given my Horse Shoe site?
  • How does recent weather (wet seasons) affect my expected pumping interval?
  • What maintenance tasks can I perform myself, and what requires a licensed technician?
