- 500 Gallon Capacity: Suitable for up to 4–6 people in a typical household, with a hydraulic retention time optimized for effective solid-liquid separation.
- UV-Resistant Coating: A specialized outer coating protects the tank from degradation caused by sunlight, ensuring a long service life when installed above ground or in exposed areas.
- 3-Part Sealing System: This advanced sealing mechanism includes a primary gasket, a secondary compression seal, and a locking ring, delivering triple protection against leaks and odors.
- Corrosion & Chemical Resistance: SMC is inherently resistant to acids, alkalis, and sewage gases, eliminating the risk of rust or decay.
- Easy Installation: The tank can be installed in a variety of soil conditions with minimal excavation. It is designed to be backfilled with soil or gravel without additional support structures.
