Product Description

SUNMORE Factory Anti-Compression Underground Septic Tank

Anti-Corrosion HDPE Domestic Wastewater Separation Tank designed for reliable underground sewage treatment applications.

Product Overview

The SUNMORE Factory Anti-Compression Underground Septic Tank is an integral rotational molding buried sewage treatment tank manufactured using thickened modified HDPE raw material with corrugated reinforced structure. This seamless three-chamber separation purification system provides strong underground compression resistance, excellent anti-corrosion properties, and fully leakproof performance for domestic sewage treatment.

Key Features & Benefits

Corrugated Reinforced Anti-Compression Structure: Circular corrugated reinforcement ribs evenly disperse soil pressure, preventing collapse, deformation, or cracking in various geological environments.
Modified HDPE Material: Industrial anti-aging HDPE resists erosion from domestic sewage, sludge, organic acids, and underground corrosive substances with a service life exceeding 50 years.
One-Piece Rotomolded Seamless Design: Fully closed cavity formed by one-time rotational molding eliminates welding and joint leakage risks, preventing groundwater and soil pollution.
Three-Chamber Integrated Wastewater Separation: Independent partition structure enables primary sedimentation, anaerobic degradation, and secondary filtration to effectively reduce sewage COD values.
Lightweight Construction & OEM Customization: Lighter than cement tanks for easier transportation and installation, with full customization of volume, pipe positions, diameters, and branding.

Frequently Asked Questions

Can this anti-compression septic tank withstand heavy soil pressure after full burial?

Yes. The corrugated reinforced ribs cooperate with thickened tank wall to uniformly bear overlying soil pressure, providing strong compression resistance that prevents deformation or cracking after decades of buried use.

Will the HDPE tank corrode and leak after long-term contact with sewage?

The modified HDPE material resists acid, alkali and sludge corrosion. The integral seamless molding eliminates leakage risks, preventing water seepage problems common with cement tanks.

What customization can be provided for municipal environmental engineering orders?

We can adjust internal volume, change inlet/outlet pipe sizes and positions, print engineering brand logos on the tank surface, and develop special size molds according to specific construction site geological conditions.

Great value for money. Compared with other brands, SUNMORE's molds have longer service life and more reasonable prices. We plan to expand our order quantity next time.

We purchase full range tapered rotomolded barrels from 50L to 5000L to match diversified raw material storage of our integrated chemical factory. The tapered design facilitates complete material pouring without leftover residue, seamless one-piece PE structure prevents leakage of granular and mild corrosive liquid raw materials.
