1.5m³ SMC FRP Septic Tank | Three-Chamber Sewage Treatment Tank SMC FRP Septic Tank | DISLAB Composite

1.5m³ Standard Three-Chamber Septic Tank

SMC molded fiberglass-reinforced plastic | High-strength · Leak-proof · Engineered for rural sanitation

Product Overview

This standard 1.5m³ SMC molded fiberglass-reinforced plastic (FRP) septic tank is engineered as a three-chamber sedimentation solution for rural domestic sewage treatment and dry toilet renovation projects. Manufactured from high-strength SMC composite material with a tensile strength ≥60 MPa, the tank offers exceptional structural rigidity, corrosion resistance, and leak-proof performance. Suitable for plains, mountainous regions, arid/semi-arid zones, and high-altitude cold areas.

Daily treatment capacity: 1.5m³/day · Influent SS ≤200mg/L · Effluent SS ≤20mg/L · 90-day sedimentation cycle. Fully compliant with decentralized sanitation standards.

Core Product Advantages

🏭 High-Strength SMC Molded Construction

One-piece SMC molding with tensile strength ≥60 MPa. High hardness, impact & crack resistance, eliminating structural deformation during long-term underground use.

💧 Enhanced Leak-Proof Three-Chamber Design

Raised partition slots + thickened baffles, staggered pipe openings, structural sealant and rubber gaskets with 100mm overlap for full watertight performance.

🔒 Reinforced Cover & Secure Access Lid

Heavy-duty reinforced cover withstands backfill and light vehicle traffic. Rotating lockable lid with “inlet (hazard)” / “outlet (non-hazard)” markings.

⚡ Fast Installation & Low Maintenance

Modular assembly, quick on-site assembly. Only sludge pumping every 1-2 years needed. Minimal operational cost for rural households.

Common Applications & Problem Solving

🚽 Dry Toilet Renovation

Hygienic, odor-free solution upgrading traditional pit latrines, eliminating pathogens and improving rural sanitation.

🏡 Decentralized Sewage Treatment

Ideal for remote areas without centralized sewer systems, compact self-contained solution for households.

🌍 Leakage & Groundwater Protection

Fully sealed design prevents untreated sewage from seeping into soil, protecting local groundwater resources.

⛰️ Adaptability to Harsh Environments

Withstands extreme temperatures, soil pressure, uneven terrain. Perfect for mountainous, arid, and high-altitude regions.

Installation Steps (Quick Assembly)
1. Apply neutral silicone sealant in clamping grooves
2. Install internal baffles (2/1/3 chamber ratio, staggered openings)
3. Fit sealing rubber gaskets with 100mm overlap
4. Install rubber rings for inlet/outlet ports
5. Fit transfer pipes facing inlet direction (staggered)
6. Lock cover parallel, secure baffles into grooves
7. Tighten screws evenly from all directions
8. Secure lids: hazard marking on inlet side, non-hazard on outlet
Delivery Case – Rural Sanitation Project in Central China

DISLAB Composite supplied 320 units of the 1.5m³ SMC molded septic tanks for a large-scale dry toilet renovation project in Hubei Province. The tanks were delivered in modular, stackable packaging to a remote mountain village, with on-site assembly completed in under 3 working days per unit. The installation included 210 units in mountainous areas and 110 units in plains locations, all passing local environmental authority inspections for leakage and effluent quality. System has been operating stably for over 2 years, treating domestic wastewater for 450+ households and eliminating groundwater pollution risks.
