Frequently Asked Questions
What's the difference between a gravity and mound septic system?
Gravity systems rely on natural slope to move wastewater downward, while mound systems are built above ground when soil conditions don't allow adequate drainage or depth. In southern Minnesota, mound systems are common where water tables are high or soil drains poorly. At Advanced Septic and Excavating LLC, we design based on your site's soil test and terrain.How does freeze-thaw affect septic systems in Minnesota?
Freeze-thaw cycles can shift soil, stress pipes, and disrupt drainage fields if systems aren't properly installed or insulated. Minnesota septic installations should account for frost depth and seasonal ground movement. We design and install systems in Le Roy to handle these conditions and maintain performance year-round.When should you schedule a septic inspection before selling property?
Schedule a septic inspection at least two to three weeks before closing to allow time for any needed repairs or documentation. Many rural property sales in Minnesota require proof of a compliant system. At Advanced Septic and Excavating LLC, we provide clear findings and recommendations for time-sensitive transactions.What affects the cost of installing a new septic system?
Cost depends on system type, soil conditions, site accessibility, and permit requirements. Mound systems typically cost more than gravity systems due to additional materials and labor. In southern Minnesota, soil variability and drainage challenges can also influence final pricing.Can septic system repairs extend the life of an older system?
Yes, timely repairs can address performance issues and prevent full system failure, especially in older rural Minnesota systems. Common repairs include fixing distribution lines, adjusting tank levels, or repairing drainage fields. At Advanced Septic and Excavating LLC, we assess problems early to help avoid costly replacements.How do soil conditions determine septic system design?
Soil type, drainage rate, and depth to bedrock or water table all dictate system design and placement. Sandy soils drain quickly, while clay soils may require mound or engineered systems. We evaluate soil conditions on-site in Le Roy and surrounding areas to ensure compliant, long-lasting septic performance.What's included in a septic system evaluation for new construction?
An evaluation includes soil testing, site layout review, system design recommendations, and guidance on county permitting. It ensures the septic system will meet regulatory standards and perform reliably. At Advanced Septic and Excavating LLC, we help property owners plan installations that fit their land and budget.Why do rural properties in Minnesota need private septic systems?
Most rural areas in southern Minnesota lack access to municipal sewer lines, making private septic systems the only option for wastewater treatment. These systems are designed to handle household waste on-site and must comply with state and county health regulations to protect groundwater.How does proper excavation impact septic system performance?
Accurate excavation ensures correct system depth, slope, and drainage field placement, all critical for long-term function. Poor grading or improper trenching can cause pooling, backup, or early failure. We handle all excavation in-house to maintain quality control and meet Minnesota installation standards.What's the biggest mistake people make with septic maintenance?
The biggest mistake is ignoring early warning signs like slow drains, odors, or wet spots near the drain field. Delaying repairs can turn minor issues into expensive system failures. At Advanced Septic and Excavating LLC, we encourage on-site assessments at the first sign of trouble.
