Product Description

Sunmore Rotomolded Assembled Three-Chamber Septic Tank

Underground Split PE Sewage Treatment Tank For Rural Household Toilet Renovation

Product Overview

The Sunmore Rotomolded Assembled Three-Chamber Septic Tank is a segmented assembled septic tank independently produced by Sunmore Roto. It adopts thickened food-grade PE raw material through integrated rotational molding, featuring a split combined three-chamber structure with underground buried design. The rib-reinforced tank wall significantly improves compression resistance and anti-deformation capacity. Primarily applied to rural household toilet renovation, new countryside construction, village domestic sewage purification, and residential underground wastewater treatment projects. We support OEM customization with adjustable tank total volume, single cabin size, inlet & outlet position, and wall thickness according to customer construction drawings.

Key Features & Benefits

Thickened Reinforced PE Material: Excellent anti-corrosion and anti-aging performance with high-density thickened polyethylene containing anti-UV and anti-aging additives. Resists long-term erosion from domestic sewage, sludge, and underground soil acid-base substances. No rust, no corrosion, with stable underground service life exceeding 20 years.
Split Assembled Three-Chamber Structure: Efficient sewage separation and purification through three independent sedimentation cabins connected by assembly joints. Provides graded sedimentation, anaerobic fermentation, and step-by-step sewage purification. Effectively separates solid manure and wastewater, reduces blockage risk, and improves sewage discharge standard compliance. Split design lowers transportation costs and overcomes oversize whole tank logistics limitations.
Vertical Rib Reinforced Tank Wall: Strong buried compression resistance with integrated vertical reinforcing ribs that evenly disperse underground backfill soil pressure. Maintains structural integrity without deformation or cracking under vehicle load, suitable for roadside, courtyard, and road side buried installation scenarios.
Fully Sealed Assembly Interface: Zero sewage leakage risk with splicing flanges matched with special rubber sealing strips and multi-group locking fasteners. Ensures tight fit between tank segments, completely preventing sewage seepage and underground soil pollution while meeting national rural sewage treatment environmental protection standards.
Multi-Dimensional OEM Customization: Matches different engineering demands with customizable total tank volume, single cabin capacity, inlet/outter caliber and position, tank wall thickness, and overall length-width dimensions. Available in small household types, large centralized village types, and special specification tanks for engineering projects.

Frequently Asked Questions

What customization options are available for this assembled three-chamber septic tank?

We support full OEM customization including total tank volume, single cabin size, inlet/outlet hole position and diameter, tank wall thickness and overall outer dimensions to fit different rural and villa construction projects.

Can this split septic tank bear vehicle pressure after underground burial?

The tank wall is designed with vertical integrated reinforcing ribs to evenly disperse soil pressure. Conventional small vehicles can pass above normally; for heavy truck roads, we can customize thicker wall and extra reinforcement structure.

How to guarantee no sewage leakage at the splicing joints?

Each split flange is equipped with matched thick rubber sealing strips and multiple locking buckles to fully compress the joint surface, forming a fully sealed cavity and completely avoiding underground sewage leakage pollution.

We equipped our industrial park water supply project with multiple sets of 10-ton roto water tanks. Rotomolding integrated forming avoids leakage risks, and the product can keep continuous operation as designed. We will place repeat orders for our new expansion project soon.

We purchase various specifications from 0.5T to 10T cylindrical horizontal tanks to install on farm transport trucks for liquid fertilizer and pesticide delivery. Premium LLDPE material is corrosion resistant to farm chemicals, no liquid spillage even on bumpy country roads.

We ordered a large batch of 5T horizontal roto tanks for urban construction project water supply. Thickened LLDPE material ensures outstanding pressure resistance, no bulging after long-time full-load water storage. Horizontal design saves construction space and speeds up installation work.
