Engineered Septic System Upgrades
Replacing an old, collapsed steel tank or building a new home requires professional septic system installation. A poorly designed septic system can cause sewage overflows, water contamination, and immediate code violations.
Flex Sanitation works with local health officials, geologists, and civil engineers to design and install custom septic systems. We evaluate soil properties, home layout, and daily water volume to size your tank and leach field correctly.
From permitting to structural backfilling, our team manages the entire process so you don't have to worry about delays or failed county inspections.
- Complete site analysis and soil percolation testing.
- Engineering support for septic tank and absorption layouts.
- Heavy excavation and precast concrete tank placement.
- County inspections and final system certification.
