A lagoon system is an effective and affordable wastewater treatment solution for properties without access to municipal sewer systems. At Osborn Excavating, we specialize in designing and installing lagoon systems that meet Missouri Department of Natural Resources (DNR) regulations while providing reliable, long-term waste management.
Whether you're building a new home on rural acreage, upgrading an existing system, or need a lagoon for agricultural operations, our experienced team handles every aspect of the project—from initial site assessment and permitting to final grading and landscaping.
With over 25 years of experience in Central Missouri, we understand the unique soil conditions, terrain challenges, and regulatory requirements of our region.
WHAT IS A LAGOON SYSTEM?
Understanding how lagoon wastewater systems work and why they're an excellent choice for rural properties
How It Works
A lagoon system is a shallow, man-made pond that treats wastewater through natural biological processes. Sewage flows from your home into the lagoon, where bacteria break down organic matter. Sunlight, oxygen, and natural evaporation work together to treat and reduce the wastewater over time.
Key Components
A properly designed lagoon system includes inlet piping from your home, a lined or sealed basin to prevent groundwater contamination, proper depth and surface area calculations, overflow protection, and surrounding berms for safety and containment.
Ideal Applications
Lagoon systems are perfect for rural homes without sewer access, farms and agricultural operations, properties with high water tables where septic systems aren't viable, and locations where soil conditions don't support traditional drain fields.
Maintenance Needs
Lagoons require minimal maintenance compared to septic systems. Occasional mowing around the berms, keeping the area free of trees and shrubs, and periodic inspections are typically all that's needed to keep your system functioning properly for decades.
OUR LAGOON INSTALLATION PROCESS
A proven approach that ensures your lagoon system is built right the first time
Site Assessment
We evaluate your property's soil conditions, topography, water table depth, and setback requirements to determine the optimal lagoon location and size.
Design & Permits
Our team designs your lagoon system to meet Missouri DNR specifications and handles all permit applications and approvals on your behalf.
Excavation
Using professional-grade equipment, we excavate the lagoon basin to precise specifications, construct proper berms, and install all necessary piping.
Final Inspection
We coordinate the final inspection with local authorities, ensure everything meets code, and provide you with all documentation for your records.
BENEFITS OF LAGOON SYSTEMS
Why more rural property owners are choosing lagoon systems over traditional septic
Cost Effective
Lagoons typically cost less to install than conventional septic systems with drain fields, especially on properties with challenging soil conditions.
Low Maintenance
Unlike septic tanks that require periodic pumping, lagoons are largely self-maintaining through natural evaporation and biological processes.
Long Lifespan
A properly constructed lagoon can function effectively for 30+ years with minimal intervention, providing reliable wastewater treatment for decades.
Flexible Siting
Lagoons can be installed on properties where poor soil percolation or high water tables make traditional septic drain fields impossible.
Environmentally Friendly
Natural treatment processes mean no chemicals or electricity needed. The system works with nature to safely process household wastewater.
Code Compliant
We design and install all lagoon systems to meet or exceed Missouri DNR requirements, ensuring your system passes inspection the first time.

FREQUENTLY ASKED QUESTIONS
Common questions about lagoon excavation and installation
How much does a lagoon system cost to install?
Lagoon installation costs vary based on size, soil conditions, and site accessibility. Most residential lagoon systems in our area range from $8,000 to $15,000 installed. We provide free on-site estimates so you'll know exactly what to expect before work begins.
How much land do I need for a lagoon?
Missouri DNR requires specific setbacks from property lines, wells, and buildings. Generally, you'll need at least 1-2 acres to accommodate a residential lagoon with proper setbacks. The lagoon itself is typically sized at about 1 acre of surface area per bedroom.
Do lagoons smell bad?
A properly designed and maintained lagoon should produce minimal odor. The aerobic bacteria that treat the waste require oxygen, which is why lagoons are designed with large surface areas. Occasional mild odor may occur during temperature changes, but significant smell usually indicates a problem that can be addressed.
How long does installation take?
Most residential lagoon excavations are completed in 2-4 days, depending on size and soil conditions. The permitting process typically takes 2-4 weeks. From initial contact to completed installation, plan for approximately 4-6 weeks total.
Do I need a permit for a lagoon?
Yes, all lagoon systems in Missouri require a permit from the Missouri Department of Natural Resources or your local health department. We handle the entire permitting process for you, including site plans, applications, and coordinating inspections.
