Product Description

Product Overview

SUNMORE ROTO OEM Custom Rotomolded Plastic Septic Tank is an integrated seamless sewage treatment container manufactured using thick industrial-grade LLDPE raw material. Formed by one-time rotational molding without any splicing or welding seams, the tank features multi-layer ring reinforcing ribs for enhanced compression resistance and black anti-UV masterbatch to resist outdoor aging and inhibit algae growth. This corrosion-resistant, leak-proof, lightweight septic tank offers long service life and is widely applied in rural household sewage purification, villa domestic wastewater treatment, scenic spot temporary sewage storage, and community decentralized sewage disposal projects. Complete OEM customization service is available for volume, dimensions, wall thickness, inlet/outlet positions, and internal layout adjustments.

Key Features & Benefits

Integral Seamless Rotomolded Body: One-step rotomolding technology eliminates welding joints, thoroughly preventing sewage leakage and protecting underground soil and groundwater from contamination.
Thickened Industrial LLDPE Material: Resists acid, alkali, salt, and domestic sewage corrosion. Anti-UV black masterbatch prevents cracking, embrittlement, or deformation, ensuring service life over 15 years.
Multi-Layer Circumferential Reinforcing Ribs: Distributed on the tank outer wall to significantly improve compression and impact resistance, ensuring stability under soil pressure after burial.
Black Light-Shielding Tank Body: Completely blocks light penetration to inhibit algae and moss reproduction, slow sludge spoilage, and reduce maintenance frequency.
Full-Dimensional OEM Customization: Multiple standard volumes available (1000L, 2000L, 4000L) with support for custom dimensions, wall thickness, and pipeline layout adjustments.

Frequently Asked Questions

Can the tank volume, overall size and pipeline hole positions be fully customized?

Yes, we provide full OEM customization service. We can adjust the tank's overall dimensions, wall thickness, and set the quantity, position and thread standard of sewage inlet, outlet, overflow and sludge cleaning holes according to your rural construction space and pipeline design drawings.

Can the black tank effectively slow down algae and sludge reproduction inside?

The tank is blended with black anti-UV masterbatch, which fully blocks ultraviolet and visible light. Without light, algae and moss cannot reproduce inside the tank, slowing sludge decay and lowering maintenance costs.

Is this PE septic tank suitable for long-term underground buried installation?

The tank body is equipped with multi-layer circumferential reinforcing ribs for strong compression resistance. Thick LLDPE material resists soil corrosion and underground pressure, and can work stably underground for more than 15 years without deformation or leakage.

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 installed dozens of 15T horizontal water tanks for city road infrastructure supporting water supply. Thick LLDPE material brings great pressure resistance, no deformation after long-term full water storage. Horizontal layout is convenient for underground and ground installation.

This custom rotomolding steel mold works perfectly. The inner floral pattern is clear and delicate, and the HDPE water tanks produced have even wall thickness without any flaws. Highly recommend it!
