Installing a septic system is one of the most significant infrastructure decisions a homeowner can make. A properly designed and installed system handles every gallon of wastewater your home produces for decades, while a poorly designed one becomes an expensive, recurring problem from day one. At Bayou Teche Septic, we install complete septic systems for new construction, replace failed systems on existing properties, and upsize systems when home additions or expanded household use have outgrown the original design.
Every installation we do follows current Louisiana Department of Health standards for setbacks, sizing, soil testing, and component selection. The process begins with a site evaluation, including a soil percolation test to determine how well your ground can absorb and treat effluent. Based on that data and your household size, we design a system that fits your property and meets all parish and state requirements.
Lafayette Parish and the surrounding Acadiana region are dominated by heavy clay and prairie soils that drain slowly. The water table sits high during the wet months, and many properties have flat topography that limits natural drainage. These conditions mean drain fields must be sized correctly, oriented properly, and in some cases supplemented with aerobic treatment units or pressure-distribution systems to function reliably. Skipping the soil test or installing a one-size-fits-all system in this region is a recipe for premature failure.
After the design is approved, our crew schedules excavation and installation. A typical residential installation takes one to three days depending on system complexity, soil conditions, and weather. We protect existing landscaping where possible, restore the site to grade after work is complete, and walk you through how to maintain your new system for maximum longevity.
A complete residential septic installation in the Lafayette area typically ranges from $5,000 to $12,000 depending on system size, soil conditions, and whether an aerobic treatment unit is required. Aerobic systems and pressure-distribution systems for difficult sites cost more, but they can be the only practical solution for properties with very poor soil percolation. We provide a detailed written estimate after the site evaluation so you know exactly what's included.
