Service Overview
Mound System Installation Backed by 65+ Years of Local Experience
Not every Central Florida property can support a standard in-ground septic system. When soil conditions are poor, the water table is high, or the ground simply can't absorb and filter wastewater the way a conventional system requires, a mound system is often the answer. Mound systems are engineered to work with your property's limitations — raising the drainfield above grade so wastewater is properly treated before it ever reaches groundwater. It's a smarter solution, not a compromise.
At Lapin Services, we've been installing septic systems across Central Florida since 1958. We know this region's soil, its water tables, and its county requirements inside and out. When your property calls for a mound system, we handle everything — from the initial site evaluation and permit applications through installation and final inspection. No guesswork. No surprises. Just a properly functioning system that's built to last and compliant from day one.
Problems We Solve
Common Mound System Installation Problems We Fix
Here are the issues our team commonly finds and resolves during mound system installation calls across Central Florida.
High Water Table
Central Florida's flat terrain and frequent rainfall mean many properties sit above shallow groundwater. A standard drainfield buried in saturated soil can't treat wastewater effectively — it has nowhere to go. A mound system elevates the treatment zone above the water table, giving effluent the filtration distance it needs to be safely absorbed.
Poor Soil Permeability
Some soils — including dense clay and hardpan common in parts of Central Florida — absorb water too slowly for a conventional drainfield to function properly. When a percolation test reveals inadequate drainage, a mound system introduces engineered fill material that provides the right conditions for safe wastewater treatment regardless of what's naturally below.
Shallow Bedrock or Hardpan Layers
Subsurface rock or impermeable hardpan layers can make it impossible to bury a traditional drainfield at the required depth. Rather than forcing a system that won't work, a mound system builds upward — bypassing the problem entirely and meeting all Florida Department of Health installation standards.
Failing Conventional System on a Difficult Lot
If your existing septic system is backing up or failing and the soil conditions that caused the problem haven't changed, a standard replacement often isn't the right fix. A mound system may be the correct long-term solution — addressing the underlying soil or drainage issue rather than repeating the same installation in the same compromised ground.
New Construction on a Challenging Site
Building on a lot that doesn't pass standard soil testing doesn't have to derail your project. A properly engineered mound system can make otherwise unbuildable lots viable, giving you the ability to move forward with construction while meeting all county health and environmental requirements.
When to Call
Signs Your Septic System Needs Professional Attention
If you notice any of these warning signs, schedule mound system installation before the problem becomes more disruptive or expensive.
Your Property Failed a Perc Test
A failed percolation test is often the first official signal that a conventional septic system won't work on your lot. Rather than walking away from the property or delaying a build, a mound system evaluation is your next step — and Lapin can walk you through exactly what that means for your site.
Standing Water or Soggy Ground Near Your Drainfield
If the area around your existing drainfield stays wet, has an odor, or shows patches of unusually lush green grass, your system may be failing because the soil can't keep up. This is a classic sign of a drainage problem that a mound system is specifically designed to solve.
Sewage Odors in Your Yard
Persistent odors near your septic area — especially after rain — often indicate that effluent isn't being treated or absorbed properly. On lots with poor drainage, this problem recurs no matter how often you pump. A mound system addresses the root cause instead of masking the symptom.
You're Replacing a System That Keeps Failing
If you've repaired or replaced your septic system more than once and problems keep coming back, the issue likely isn't the system itself — it's the soil conditions it's installed in. A mound system engineered to match your property's specific limitations can break the cycle for good.
Your County Requires an Alternative System
Some Florida counties and health departments require an alternative septic system — including mound systems — for properties that don't meet conventional installation criteria. If you've received a notice or your permit was denied for a standard system, Lapin can evaluate your property and install the required system with all the proper permits and inspections handled for you.
Our Process
What to Expect From Your Mound System Installation Visit
Lapin keeps the process straightforward from the first call through final documentation, so you know what is happening at every step.
Step 1
Site Evaluation and Soil Assessment
We start with a thorough evaluation of your property — reviewing soil conditions, water table depth, lot size, and any previous septic history. This gives us the information we need to determine whether a mound system is the right fit and what size and design your site requires.
Step 2
System Design and Permitting
Our team designs a mound system engineered to meet Florida Department of Health requirements and your county's specific codes. We prepare and submit all permit applications and handle coordination with inspectors so you don't have to navigate the paperwork maze on your own.
Step 3
Site Preparation
Before installation begins, we prepare the area — clearing vegetation, grading the ground surface, and laying the groundwork for the mound structure. Proper site prep is essential to a mound system that performs correctly for decades, and we don't cut corners here.
Step 4
Mound Construction and System Installation
Our licensed crews build the mound using approved fill material, then install the distribution system, piping, and all components according to the permitted design. Every step follows Florida's strict installation standards — because anything less puts your property and your investment at risk.
Step 5
Inspection, Testing, and Handoff
Once installation is complete, we coordinate the required county inspection, confirm the system passes all tests, and walk you through how your new mound system works — including what to expect for maintenance going forward. You'll have documentation of everything and a team you can call anytime.

FAQs
Mound System Installation FAQs
What is a mound septic system and how does it work?
A mound system is an alternative septic system designed for properties where soil conditions — such as a high water table, poor permeability, or shallow bedrock — prevent the installation of a conventional in-ground drainfield. Instead of burying the drainfield below grade, the system builds an engineered mound of approved fill material above the natural ground surface. Wastewater from your home flows to a septic tank, where solids settle out, and the liquid effluent is pumped up into the mound. As it filters down through the fill material and into the native soil below, it’s treated by naturally occurring bacteria before reaching groundwater. The elevated position gives the system the treatment distance it needs to function safely even in challenging conditions.
Does my property need a mound system?
Not every property does — but in Central Florida, a significant number of lots have soil or drainage conditions that make conventional systems impractical or non-compliant. The most reliable way to find out is a professional site evaluation and soil assessment. If your lot has failed a percolation test, if you’re experiencing recurring drainfield problems, or if your county has indicated that an alternative system is required, a mound system may be exactly what your property needs. Lapin can evaluate your site and give you a clear, honest answer about your options.
How long does a mound system installation take?
The installation itself typically takes one to three days once permits are in hand and the site is prepared. The total timeline from initial evaluation to a fully permitted and inspected system depends on how quickly your county processes the permit application and schedules inspections. Lapin manages the entire permitting process on your behalf to keep things moving as efficiently as possible. We’ll give you a realistic timeline during your initial consultation so you know what to expect.
How much does mound system installation cost in Orlando?
Mound system installation costs vary based on the size of the system your property requires, site-specific conditions, and current permitting fees. Because every lot is different, we can’t provide a meaningful number without evaluating your specific property. What we can promise is honest, transparent pricing — no surprises once we give you a quote. Call us at (407) 326-3367 or schedule a site evaluation and we’ll give you a clear picture of what your project will cost.
Are mound systems approved in Orange County and surrounding Florida counties?
Yes. Mound systems are an approved alternative septic system under Florida Department of Health regulations and are permitted in Orange, Osceola, Seminole, Lake, Polk, and other Central Florida counties. Each county may have slightly different requirements and inspection processes, and Lapin’s team is familiar with all of them. We handle the permit applications and inspector coordination for every installation we perform.
How do I maintain a mound system?
Mound systems require the same basic care as any septic system — regular pumping (typically every three to five years, depending on household size and usage), avoiding flushing non-biodegradable materials, and keeping heavy vehicles and deep-rooted plants away from the mound area. Because mound systems include a pump, you’ll also want periodic inspections of the pump and controls to catch any mechanical issues early. Lapin offers ongoing maintenance and inspection services, so you have a single trusted partner for the life of your system.
Can a mound system handle the same load as a conventional septic system?
Yes — a properly sized and installed mound system is designed to handle your home or facility’s daily wastewater load just as effectively as a conventional system. The key word is “properly sized.” During our site evaluation, we calculate the system size your property requires based on the number of bedrooms, expected water usage, and site conditions. An undersized system will struggle; a correctly engineered one will perform reliably for decades.
What happens if my mound system fails or has a problem after installation?
Lapin stands behind every installation we perform. If you experience a problem with your mound system — whether it’s a pump failure, drainage issue, or anything else — call us at (407) 326-3367. We’re available 24/7 and can diagnose and address problems quickly. Because we installed your system and know it inside and out, you won’t be starting from scratch explaining your setup to someone who’s never seen it before.
