Key Features & Technical Specifications
- Material Excellence: Constructed from high-strength SMC (Sheet Molding Compound), FRP (Fiberglass Reinforced Plastic), and GRP (Glass Reinforced Plastic), offering exceptional corrosion resistance, UV stability, and a service life of over 30 years.
- Integrated Biogas Recovery: Built-in anaerobic digestion chamber with a gas collection system captures methane-rich biogas, which can be used for cooking, heating, or lighting, reducing household energy costs.
- Compact & Lightweight Design: Molded as a single piece, the tank is lightweight (approx. 150–300 kg depending on capacity) and easy to transport and install without heavy machinery.
- Seamless Structure: No joints or welds, eliminating leakage risks and ensuring long-term durability.
- High Efficiency Treatment: Achieves up to 70–80% BOD (Biochemical Oxygen Demand) reduction, meeting local discharge standards for household sewage (optional tertiary treatment add-on available).
- Easy Maintenance: Large inspection ports allow for simple sludge removal and biogas system checks.
- Customizable Sizes: Available in capacities from 1m³ to 5m³, suitable for 1–10 person households.

Frequently Asked Questions (FAQ)
- Q: What is the lifespan of the SMC/FRP/GRP septic tank? A: Under normal operating conditions, the tank can last 30 years or more due to the corrosion-resistant composite material. UV-resistant coatings add extra protection for above-ground installations.
- Q: How does the biogas recovery system work? A: Anaerobic bacteria break down organic matter in the sewage, producing methane and carbon dioxide. The gas is collected in a sealed chamber and routed to a gas outlet pipe. You can connect it to a gas stove, heater, or lamp using a simple gas line and regulator (gas appliances not included).
- Q: What is the typical biogas yield for a household? A: For a family of 4–5 people, expect 0.3–0.5 m³ of biogas per day, equivalent to about 1–2 hours of cooking on a medium burner. Yield depends on temperature, organic load, and retention time.
- Q: Can the tank be installed in cold climates? A: Yes, the tank is designed for underground installation where soil temperature remains relatively stable. For extremely cold regions, optional insulation or a heating element can be added. The anaerobic process works best above 10°C.
- Q: Do you provide installation instructions? A: Yes, we provide detailed installation manuals and technical drawings. We also offer remote guidance via video call. For large orders, on-site training may be arranged.
- Q: What maintenance is required? A: Sludge should be removed every 1–3 years depending on usage. The biogas system requires occasional checking of the gas valve and pipe connections. No special tools or chemicals are needed.
- Q: Can I customize the inlet/outlet positions? A: Absolutely. We can customize the tank’s inlet and outlet diameters and positions to match your existing plumbing. Please provide your requirements when ordering.
- Q: Is the tank suitable for use with a garbage disposal unit? A: It is recommended to avoid excessive solid waste. The tank is designed for typical household sewage (toilet, kitchen, laundry). A separate grease trap may be needed for heavy kitchen waste.
