🌱🚽 What Is a Coco Tank? A Greener Way to Treat Wastewater
Looking for an eco-friendly septic solution? Meet the Coco Tank—a sustainable wastewater treatment system that uses natural coconut husk fibers to filter and clean effluent from your septic tank.
🔍 How It Works:
After wastewater leaves your septic tank, it flows into the Coco Tank, where it passes through layers of coconut husk media. These fibers act as a powerful natural filter, removing pollutants through physical, chemical, and biological processes.
🌿 Why Choose a Coco Tank?
✅ Uses renewable coconut husks instead of synthetic materials
✅ Requires no energy for treatment—it's a passive system
✅ Compact design—takes up 50% less space than traditional systems
✅ Ideal for small lots, rocky soils, or areas with high water tables
✅ Filter media lasts 10–15 years and is compostable after use
🛠️ Maintenance Made Simple
Coco Tanks are low-maintenance, but regular care ensures optimal performance:
🔹 Annual inspection by a certified technician is required
🔹 Effluent filter cleaning and sludge level checks in the septic tank
🔹 Raking or refreshing the coconut media if needed
🔹 Media replacement every 10–15 years (cost: ~$1200–$1500)
🔹 Optional: UV disinfection or phosphorus removal units can be added for extra treatment
Clarke County Environmental Health holds maintenance contracts for each coco tank known to have been installed in Clarke County in order to assist in the protection of homeowners and our aquifer. If you have questions about whether you have a maintenance contract on file, please call 641-223-8299!
