2. Made of high-strength glass fiber material composite, using integral molding technology without joints, good tightness, acid and alkali corrosion resistance, no leakage, and no pollution of groundwater sources;

3. The appearance is designed and manufactured in the shape of a round barrel, with square steel reinforcement ribs inside the barrel. The two end heads are designed and manufactured with wheel shaped concave and convex surfaces, with high compressive strength, acid and alkali corrosion resistance, and a normal service life of over 50 years;

4. The cylinder is equipped with two compartment plate circulation flooding devices, which change the traditional septic tank's direct flow flooding to circulation flooding and increase the retention time of sewage. This effectively solves the problem of effective volume reduction after water short circuit in traditional septic tanks, greatly enhances the biodegradation ability, improves the anaerobic effect of sewage treatment process, reduces the COD and ammonia nitrogen index in sewage by more than twice, and lays the foundation for the subsequent deep treatment of sewage;

5. The overall installation and construction are fast, with a short construction period, and slot installation can be completed in just one day;

6. The final settlement price is about 10% to 20% lower than that of traditional steel-concrete septic tanks.

This glass reinforced plastic septic tank has good overall production tightness, no leakage, and completely solves the problem of underground water pollution caused by brick built septic tanks. It improves the environmental function, improves the operation of septic tanks, and ensures the anaerobic decay function of septic tanks. Practice has proven that its cleaning time is three to five times that of brick built septic tanks, which brings great convenience to property management. The increasing number of underground pipelines such as gas, water supply and drainage, rainwater, telephone, electricity, cable TV, and geothermal air conditioning in residential areas can save land and improve the comprehensive facilities of the pipeline network
