We pump and clean septic tanks to remove sludge before it reaches the outlet pipe or drain field. Each visit can also include checks of baffles, lids, tank walls, and inlet and outlet pipes.

New septic systems are designed around soil conditions, household demand, and available drain field space. We install conventional and alternative systems while following New Hanover County requirements.

Inspections evaluate the tank, distribution box, piping, and drain field for damage or poor performance. We check sludge levels, baffles, structural condition, and signs of drain field saturation.

We repair cracked components, damaged pipes, clogged effluent filters, failed baffles, distribution boxes, and root intrusion. Technicians identify the source before recommending the most practical repair.

Failed or outdated systems may require full replacement. We size and install new tanks and drain fields based on bedroom count, wastewater demand, soil conditions, and approved plans.

Routine maintenance helps prevent backups and premature drain field failure. Services may include pumping, filter cleaning, sludge monitoring, access-point checks, and drain field evaluation.

We diagnose standing water, sewage odors, surfacing effluent, and poor drainage. Services include pipe clearing, soil evaluation, drain field repair, and partial or full replacement.

System design accounts for lot size, soil conditions, groundwater, setbacks, and wastewater demand. We also coordinate required permitting through New Hanover County Environmental Health.

Urgent service is available for sewage backups, overflowing tanks, clogged lines, and drain field failures. We identify the cause, stabilize the system, and recommend any necessary repairs.

We locate buried septic tanks when records are missing or inaccurate. Probing and locating methods help find access points without unnecessary excavation.

Septic backups require both cleanup and correction of the underlying problem. We address wastewater, clogged pipes, full tanks, or saturated drain fields to reduce contamination and prevent repeat issues.


Commercial systems must be sized for occupancy, wastewater volume, soil conditions, and business type. Services include site evaluation, percolation testing, system design, permitting, excavation, and installation to New Hanover County requirements.

Inspections help identify leaks, blockages, structural damage, and drain field problems before they disrupt operations. We check sludge levels, effluent flow, tank condition, saturation, and permit compliance.

High-use systems often require fast repairs to prevent closures or sanitation issues. We repair clogged lines, damaged baffles, failing pumps, cracked tanks, and other commercial-grade components.

When repeated repairs are no longer practical, we replace failing tanks, drain fields, and related components. New systems are sized for current wastewater demand and installed around business operations whenever possible.

Preventive maintenance reduces emergency repairs and extends system life. Scheduled service may include pumping, filter and baffle inspections, effluent monitoring, and pump or float-switch testing.

We inspect and repair commercial drain fields affected by saturation, soil compaction, root intrusion, or damaged lines. Solutions may include line repair, field expansion, or complete drain field replacement.

Restaurants and food service businesses need grease traps maintained to control fats, oils, and grease. We provide pumping, cleaning, component inspections, and service documentation for compliance records.

Commercial lift stations require dependable pumps, float switches, and alarms to move wastewater safely. We inspect, repair, and maintain these components to reduce backups and unexpected pump failures.
Aerobic treatment units use oxygen to treat wastewater and require regular maintenance. We inspect aerators, compressors, alarms, disinfection units, spray heads, and drip lines to keep these systems operating properly.

Properties with high water tables, poor soil, or limited space may rely on alternative septic designs. We service mound systems, sand filters, low-pressure pipe systems, peat filters, and other engineered configurations.

Holding tanks store wastewater without a drain field and must be pumped regularly. We provide scheduled pumping for seasonal properties, temporary sites, cabins, and locations awaiting septic installation or repair.

We repair and replace effluent pumps, sewage pumps, grinder pumps, float switches, alarms, timers, and control panels. Accurate troubleshooting helps prevent backups and premature pump failure.

Wastewater testing helps verify that treatment systems are working properly. We can evaluate parameters such as biochemical oxygen demand, total suspended solids, and fecal coliform when required for troubleshooting or compliance.

We assist with permits, system evaluations, maintenance records, and other septic documentation required by local authorities. This helps property owners stay compliant during repairs, installations, and property transactions.

Some failing systems can be restored without complete replacement. We evaluate drain field condition, soil performance, component age, and permitting requirements before recommending rehabilitation or replacement.

We provide wastewater pumping for RV holding tanks and certain marine sanitation systems. On-site service offers a practical option for private properties, storage facilities, and marine locations requiring proper waste removal.

Every job starts with a site assessment of the tank, access points, drain field, soil conditions, and wastewater flow. Depending on the service, the process may include:
Findings and recommended repairs are explained clearly before work moves forward.
Materials are selected based on soil conditions, groundwater levels, system design, and property needs. Options include:
Choosing the right materials for each site helps improve durability, drainage, and overall system performance.
Wastewater flows into a septic tank, where solids settle and bacteria break down organic waste. Liquid effluent then moves to the drain field, where soil naturally filters it before it reaches groundwater.
Properties without access to a municipal sewer typically need a septic system. This is common for rural homes, low-density developments, and new construction outside existing sewer service areas.
Installation typically includes:
System size and layout are based on bedrooms, water use, soil conditions, and available space.
Most installations take 1 to 3 days after permits are approved and the site is ready. Permitting, weather, groundwater, and system complexity can extend the overall timeline.
Keep the installation area accessible and remove vehicles, furniture, or other obstacles. Property lines, wells, irrigation systems, utilities, easements, and major tree roots should also be identified before excavation begins.
New septic systems in Wilmington typically cost $6,500 to $18,000+. Conventional systems on suitable lots cost less, while properties with high water tables or poor drainage may require engineered systems.
Key cost factors include:
A site evaluation provides the most accurate estimate.
A typical installation may include:
Tank size, material, installation depth, and site access affect pricing. A three-bedroom home commonly uses a 1,000-gallon tank, while larger homes may require 1,250 gallons or more.
Concrete tanks generally cost more than plastic but offer greater durability. Tight or wooded lots can also increase labor costs.
Drain field costs depend on soil drainage, available space, groundwater depth, slope, and system design. Poorly draining soils or high water tables may require larger, raised, or engineered drain fields.
Septic permits in New Hanover County can range from a few hundred dollars to over $1,000, depending on the system and engineering requirements. Fees may cover site review, construction authorization, and final inspection.
Full septic replacement in Wilmington typically costs $8,000 to $20,000+, especially when the existing tank and drain field must be removed.
Component | Typical Cost Range |
|---|---|
Tank removal and disposal | $500–$1,500 |
New tank and installation | $3,000–$8,000 |
New drain field | $3,000–$10,000 |
Permitting and inspection | $300–$1,200 |
We provide septic pumping, repair, installation, and maintenance throughout Wilmington, New Hanover County, and nearby coastal communities, including:
Our team understands local challenges such as sandy soils, high water tables, and county septic regulations. This helps us plan compliant, reliable solutions for coastal properties and new construction.
If your location is outside these areas, contact us to check service availability.
We recommend pumping most residential septic tanks every 3 to 5 years. Tank size, household size, and daily water usage all affect how quickly solids build up.
Larger households or homes with garbage disposals may need pumping closer to the 3-year mark. We can review your tank size and usage patterns to set a schedule that fits your property.
Slow-draining sinks and toilets are often the first sign of a problem. Gurgling sounds in your plumbing or sewage odors near the tank or drain field also point to an issue that needs attention.
Standing water or unusually green, spongy grass over the drain field are additional red flags. We check for these signs during inspections and can pump or repair the system before minor issues turn into backups.
Yes, we offer same-day emergency pumping and repair for backups that can't wait. A septic backup spreads quickly and can affect your plumbing throughout the house, so we prioritize urgent calls.
Our team covers New Hanover and Brunswick County, responding to emergencies with the same equipment and expertise we use for scheduled service. Call us as soon as you notice a backup or overflow.
We perform both visual and full inspections, covering the tank, distribution box, drain field, and connecting pipes. A full inspection includes pumping the tank, measuring sludge layers, checking baffles, and probing the drain field for problems.
Beyond inspections, we handle repairs to tanks, drain fields, and sewer lines. If we find an issue during an inspection, we can typically schedule the repair without requiring a separate visit.
Grease, cooking oil, and food scraps should never go down the drain, since they don't break down and can clog pipes or the tank. Wipes, paper towels, and feminine hygiene products also cause blockages even when labeled "flushable."
Harsh chemicals, paint, and medications can kill the bacteria your septic tank needs to break down waste. We recommend sticking to toilet paper and normal household wastewater to keep your system running properly between pumpings.
