product name Durable Seamless PE Plastic Septic & Aquaculture Tank
Our three-chamber septic tank is manufactured via one-piece rotational molding with premium HDPE raw material, no splicing or welding seams to eliminate leakage risk.
The independent three-cell layout grades sewage step by step, separating sludge and wastewater effectively to meet domestic sewage purification standards, widely used for rural household underground sewage disposal.
HDPE material brings excellent acid & alkali resistance, anti-aging and high compression performance, which allows direct underground burial without collapse, with a service lifespan up to 50 years. Various volume specifications can be customized per clients' project demands for your rotomolded septic tank projects.
