MK Septic Tank Pumping & Disposal has been serving Conway, Horry County, and the surrounding South Carolina communities since 2008. That's 18 years of pump-outs, routine maintenance calls, and emergency responses for homeowners, landlords, property managers, and businesses across the area. We built this company on straightforward service, transparent pricing with no hidden fees, and a simple belief that your septic system shouldn't be a source of stress. Real people. Real pricing. Real fast response.
When you call us, you're not routed through a call center or handed off to a subcontractor. We'll be there.
Septic maintenance doesn't have to be stressful. Most homeowners and business owners don't spend much time thinking about what's happening underground, and that's perfectly fine. When you schedule a pump-out with us, we handle the details so you don't have to.
Here's what to expect when our crew arrives on-site:
We bring an experienced crew that respects your property. That means no unnecessary digging, no mess left behind, and no surprises when the job is done. The entire process is typically completed in a single visit, and we work efficiently so your day isn't disrupted more than necessary.
Keeping your tank pumped on schedule is one of the most effective ways to protect your drain field and extend the life of your entire septic system. Neglecting it long enough allows solids to migrate where they shouldn't, and that's when the real problems start.
For most residential properties in Conway and across Horry County, a pumping cycle of every three to five years is a reasonable baseline. That said, the right schedule for your system depends on several factors, including household size, daily water usage, and how long it's been since the last service.
Larger households generate more wastewater, which means solids accumulate faster. A home with five or six occupants may need service closer to every two to three years. A single-occupant property might comfortably go five years or longer between pump-outs. Every system is a little different, and we're happy to talk through what makes sense for yours when you call.
Rental properties and landlord-managed homes in Horry County often fall into a category of their own. Tenant turnover, inconsistent usage habits, and gaps in maintenance history can all contribute to faster solids buildup. If you're managing a rental and you're not sure when the tank was last serviced, scheduling a pump-out sooner rather than later is the right call.
Commercial properties and high-use systems typically need more frequent attention than residential tanks. We'll get into that in more detail below. We'll sort it out.
Whether this is your first service or your tenth, we approach every residential job the same way: show up on time, do the work right, and leave your property the way we found it.
New homeowners in Conway and Horry County often reach out because they have no idea when the tank was last pumped. That's more common than you might think. If you recently purchased a home and the seller's disclosure didn't include septic records, a pump-out is a smart first step. It gives you a clean baseline and peace of mind going forward.
We work with homeowners across a range of situations, including single-family homes on private lots, rental properties where the landlord is responsible for system maintenance, and holding tank systems that require more frequent service. Whatever your setup, we can accommodate it.
We offer flexible scheduling with no pressure to rush. You pick a time that works for your household, and we'll be there ready to work. If your schedule is tight or you need to coordinate around tenants, just let us know when you call and we'll find something that fits.
Not all septic companies operate the same way. Some focus almost entirely on residential work and treat commercial calls as an afterthought. We've been serving businesses across Conway and Horry County for nearly two decades, and commercial pump-outs are a routine part of what we do.
Restaurants, retail properties, small offices, and other businesses along Conway's commercial corridors generate significantly more wastewater than a typical household. High-use systems accumulate solids faster, which means a standard three-to-five-year residential schedule won't cut it. Falling behind on commercial septic maintenance can lead to backups, odors, and the kind of disruption that no business wants to deal with.
Property managers overseeing commercial properties in Horry County rely on us to stay ahead of these issues. We understand that timing matters for businesses, and we work to schedule service with minimal impact on your operations. Get in touch and we'll get it done.
Every system is different, but a septic emergency tends to look the same no matter the property: slow drains that won't clear, a tank that's backing up into the home, standing water or odors near the drain field, or an overflow situation that can't wait until next week.
If you're dealing with any of those signs in Conway or the surrounding Horry County area, call us. We offer same-day and after-hours service for urgent situations because we know these problems don't schedule themselves for convenient times.
When you call, we'll ask a few quick questions to understand what you're dealing with and get someone headed your way as fast as possible. We keep our pricing consistent regardless of when you need us. You'll know the cost before we start. Transparent pricing with no hidden fees applies to emergency calls just as much as routine ones.
Pick the date. We handle everything else.
Getting started is easier than you think. Pricing for septic pumping in Conway depends on a few straightforward factors, and we're happy to walk through them with you when you call.
The main variables that influence cost include:
We don't publish flat rates on the page because no two properties are identical, and we'd rather give you an accurate quote than a number that ends up being wrong. What we can tell you is that we don't add fees after the fact. The quote you get when you call is the number you can count on.
If you've been searching for affordable septic pumping in Horry County, we understand price matters. We also know that cutting corners on wastewater removal creates bigger problems down the road. Our goal is to give you honest value, not the lowest number that gets us in the door. Call for a quote and see for yourself. We'll sort it out.
Conway is our home base, but we serve customers across Horry County and the surrounding communities. If you're outside Conway proper, there's a good chance we cover your area.
We regularly provide septic pumping service to:
Whether you're in a neighborhood off Highway 501, a rural property outside Loris, or a vacation rental near the coast, we're familiar with the area and the range of septic systems that come with it.
Horry County's mix of year-round residents, seasonal properties, and commercial development means we see a wide variety of systems and service needs. That experience adds up. We'll be there.
We've been doing this work in Conway and Horry County since 2008. Over that time, we've built our reputation the same way any local company does: by showing up, doing the job right, and treating people fairly.
The person who answers the phone is often the person who drives the truck. That's not something you'll find with a national franchise or a large regional outfit. When you call us, you're talking to someone who knows this area, knows these systems, and has a direct stake in the quality of the work.
We don't require minimums, we don't pad invoices, and we don't make the process harder than it needs to be. Customers across Horry County come back to us year after year because the experience is consistent and the work holds up. No minimums. No surprises. No hassle.
When we arrive, we locate and uncover the access lid to your tank, then connect our vacuum truck to remove accumulated solids, scum, and effluent. We work carefully around the inlet and outlet baffles to ensure a thorough cleanout without disturbing the components that keep your system functioning. Once the tank is emptied, we check the visible interior and close everything back up cleanly before leaving.
Sludge is the layer of heavy solids that settles to the bottom of the tank over time, while scum is the lighter material, including fats and oils, that floats to the surface. Both accumulate naturally with every flush and drain cycle. When those layers get thick enough, they reduce the tank's effective capacity and increase the risk of solids reaching the drain field.
While the tank is being emptied, our technician checks the visible condition of the inlet and outlet baffles, looks for signs of cracking or damage to the tank walls, and notes the general level of buildup that was present. We're not performing a formal inspection, but we pay attention to what we can see and will let you know if something looks like it warrants further attention.
Wipes, paper towels, feminine hygiene products, grease, cooking oil, medications, and harsh chemical cleaners should never enter a septic system. These materials either don't break down or actively disrupt the bacterial balance that your system depends on. Keeping prohibited items out of the drain is one of the simplest ways to extend the time between pump-outs.
Most septic additives offer little to no proven benefit, and some can actually disrupt the natural bacterial environment inside your tank. The best thing you can do for your system is maintain a regular pumping schedule and avoid flushing materials that don't belong in it. We're happy to talk through maintenance habits when you call for your service.
Odors inside the house are often a sign that the tank is full or that there's a blockage preventing proper venting. A tank that hasn't been pumped in too long can push gases back through the plumbing, which is what creates that smell indoors. If you're noticing odors in your Conway home, it's worth calling us sooner rather than later to rule out an overfull tank.
We offer same-day and after-hours service for urgent situations throughout Horry County. When you call with an emergency, we ask a few quick questions to understand what you're dealing with and get someone headed your way as fast as possible. We're available every day from 6:30 AM to 9:00 PM, including weekends.
We keep our pricing consistent and explain all costs before work begins, whether it's a routine pump-out or an emergency call. When you reach us with an urgent situation, we'll give you the quote upfront so you know what to expect. There are no fees added after the fact regardless of when you need us.
The main factors that can affect the final cost include how long it has been since the last service, the level of solids buildup in the tank, and how accessible the tank lid is. We discuss these variables with you when you call for a quote so the number we give you reflects your actual situation. We don't add charges on-site that weren't part of the original discussion.
A buried or overgrown lid is a common situation, especially on older properties or homes where the system hasn't been serviced in years. Let us know when you call and we'll come prepared to locate and uncover it. We handle the digging as part of the service so you don't have to do anything ahead of time.
Heavy rain and saturated soil can affect how your septic system functions, and in some cases can make access to the tank more difficult. If you're scheduling service during or after significant rainfall in Horry County, mention it when you call. We'll factor that into our planning and let you know if conditions on your property might affect the job.
No. Driving or parking over the drain field compacts the soil and can damage the distribution pipes beneath the surface. That kind of damage is difficult and expensive to repair. Keep vehicles, heavy equipment, and anything with significant weight off the drain field area to protect the system long-term.
South Carolina requires that all septic waste be transported and disposed of at an approved facility in compliance with state environmental regulations. We follow those requirements on every job. Proper disposal protects local waterways, soil, and the surrounding community, and it's a non-negotiable part of how we operate.
A general rule is that when the combined sludge and scum layers take up more than one-third of the tank's liquid capacity, pumping becomes urgent rather than optional. At that point, solids are close enough to the outlet that they risk migrating toward the drain field. If you're not sure where your system stands, the safest move is to schedule a pump-out and let us assess what we find.
When you're ready to schedule service or just want to know what it'll cost, give MK Septic Tank Pumping & Disposal a call. We serve Conway, Horry County, and surrounding communities throughout South Carolina, and we're ready to help with routine pump-outs, urgent situations, and everything in between.

Staying on top of your septic system starts with knowing what your tank actually needs and when it needs it. The table below gives you a straightforward look at recommended pumping frequency based on household size and tank capacity. Every system is a little different, but these ranges give you a solid starting point for planning ahead and avoiding the kind of problems that come from waiting too long.
| Household Size | Tank Size (Gallons) | Recommended Pump Frequency | Signs It's Due | Notes |
|---|---|---|---|---|
| 1-2 people | 1,000 gal | Every 4-5 years | Slow drains, mild odor near tank | Low usage keeps solids accumulation slow; still worth sticking to a schedule |
| 3-4 people | 1,000 gal | Every 2-3 years | Gurgling drains, occasional backups, odors | Smaller tank with moderate use fills faster; don't push past 3 years |
| 3-4 people | 1,500 gal Most Popular | Every 3-5 years | Slow drains, soft ground above drain field, odors | Most common residential setup in Horry County; a 3-year routine keeps things predictable |
| 5-6 people | 1,500 gal | Every 2-3 years | Frequent backups, standing water near tank, strong odors | Higher usage accelerates solids buildup; don't rely on the 5-year estimate for larger households |
| 5-6 people | 2,000 gal | Every 3-5 years | Slow fixtures throughout home, wet spots above drain field | More capacity gives you flexibility, but usage habits and garbage disposal use can shorten the interval |
| 7+ people | 2,000+ gal | Every 1-2 years | Backups, persistent odors, wet ground above field | Large households put heavy demand on any system; annual or near-annual service is a smart baseline |
| Commercial / High Use | Varies | Annually or as needed | System alarms, slow fixtures across units, odors in common areas | Tenant turnover, high water usage, and multi-unit demand require a proactive maintenance schedule |
How often does a septic tank actually need to be pumped?
The honest answer is that it depends on your household size, your tank's capacity, and how the system gets used day to day. For most households in the Conway and Horry County area, a three-to-five year interval is a reasonable starting point. Smaller tanks, larger families, or homes with garbage disposals may need service more frequently. If you are not sure when your system was last pumped, calling sooner rather than later is the right move. We can help you figure out where things stand.
What are the warning signs that a septic tank is getting full?
The most common indicators are slow drains throughout the home, gurgling sounds in the plumbing, sewage odors near the tank or drain field, and wet or unusually green patches of grass above the drain field. If you are seeing backups in multiple fixtures at the same time, that is a strong signal the tank is at or past capacity. Any of these signs warrant a call. Waiting typically makes the situation more involved and more expensive to address.
What actually happens during a septic pump-out?
We locate and uncover the tank access point, connect our equipment, and pump out the accumulated solids, liquids, and scum layer. The process is straightforward for most residential systems and typically takes less than an hour. We work cleanly and leave the area in the same condition we found it. Once the tank is emptied, it is ready to return to normal use. There is nothing complicated about the process when you have the right crew on the job.
Do I need to be home when the crew arrives?
Not necessarily. As long as we can access the tank and you have given us the go-ahead to proceed, we can often complete the service without you present. We will confirm the access details when you schedule so there are no surprises on either side. After the job is done, we follow up to let you know everything went smoothly. If you do want to be on-site, we are happy to work around your schedule.
How should I prepare for a septic service appointment?
If you know where your tank lids are located, clearing the area around them is helpful. If you are not sure, that is fine too. We are experienced at locating access points. Try to avoid running large amounts of water through the system in the hours before we arrive, since a tank that is actively receiving water can be a bit more involved to work with. Beyond that, there is not much you need to do. We come prepared for the job.
What should not go down a drain connected to a septic system?
A septic system depends on a healthy balance of bacteria to break down waste. Flushing or draining things that disrupt that balance, or that simply do not break down, causes problems over time. Avoid putting grease, cooking oils, wipes labeled "flushable," feminine hygiene products, paper towels, medications, harsh chemical cleaners, bleach in large quantities, and paint down any drain connected to the system. Garbage disposals add a significant amount of solids to the tank and can shorten the interval between pump-outs if used heavily.
What is a drain field and how does it connect to my septic tank?
After wastewater is treated in the septic tank, the liquid portion flows out into the drain field, where it is filtered through the soil. The tank and the drain field work together as a system. When a tank goes too long without pumping, solids can move into the drain field and clog the soil. Drain field damage is costly and disruptive to repair. Routine pump-outs are the most straightforward way to protect that part of the system from premature failure.
What causes a septic emergency or sudden backup?
The most common cause is a tank that has simply been full for too long. When there is no room left in the tank, waste has nowhere to go except back up into the home or out onto the ground. Heavy rainfall can also saturate the soil around the drain field, temporarily reducing its ability to absorb liquid. Flushing items that do not break down can create blockages in the line between the house and the tank. In any of these situations, the right step is to call us right away. We handle urgent pump-outs and can often respond the same day.
