This septic tank boasts prominent product advantages. The seamless one-piece HDPE structure eliminates weld joints, effectively preventing sewage leakage and odour escaping. The material features outstanding anti-corrosion, anti-ageing and anti-ultraviolet properties, resisting erosion from acidic, alkaline sewage and underground soil for decades.
Adopting a flexible modular design, multiple tank units can be connected and expanded on site. Engineers can adjust the total treatment capacity according to the number of residents and daily sewage flow of the apartment building. The internal multi-chamber layout supports staged anaerobic fermentation to decompose organic pollutants thoroughly. The produced biogas can be collected and reused as clean energy.
Compared with traditional concrete septic tanks, it is lightweight for transportation, with simple installation and no concrete pouring required, cutting construction cycles and labour costs. Reinforced wall ribs improve compressive performance to bear soil overburden pressure safely.
Supplied by Guangdong Wanquan Construction Technology Co., Ltd., this product covers rich application scenarios. It is perfectly suited for mid-rise apartment buildings, multi-family residential compounds, serviced apartment blocks, suburban apartment communities and worker dormitory buildings. It is also applicable for supporting sewage treatment in mixed-use residential zones, scenic residential apartments and rural centralized apartment housing projects. It can be combined with our rainwater harvesting tanks and drainage facilities to form a complete sponge city water management system for the whole community.
