The core advantages of PP modular rainwater collection tanks compared to concrete tanks
In sponge city construction, rainwater collection tanks are key facilities. Among them, PP modular rainwater collection tanks are increasingly widely used and highly favored. So, what are their advantages compared to traditional concrete tanks? Let's take a look with Yajing Environment!
PP modular rainwater collection tanks are more practical than traditional concrete tanks and are becoming increasingly popular nowadays.
In terms of construction, traditional concrete tanks require formwork setup, pouring, and a 28-day curing period, taking 1–2 months to complete. PP modules, on the other hand, are prefabricated in factories and assembled on-site using snap-on connections. A 500-cubic-meter tank can be completed in 3–7 days, making them particularly suitable for projects with tight schedules.
Structurally, concrete tanks are heavy, require specific foundation conditions, and have fixed shapes. PP modules weigh only 1/5 of concrete tanks but possess strong compressive resistance. They can be directly buried under parking lots or green spaces and can be flexibly assembled into various shapes and sizes, making them adaptable even for narrow or irregular sites.
In terms of environmental protection and cost, dismantling concrete tanks generates a large amount of waste and maintenance is troublesome. PP modules are made from food-grade materials, are 100% recyclable, and reduce carbon emissions by 80%. Their smooth inner walls are resistant to dirt accumulation. Additionally, they can save 40% on labor costs, eliminate the need for renting formwork, and allow for future expansion, making them more cost-effective in the long run.
These are the core advantages of plastic rainwater storage tanks compared to concrete tanks, shared for reference only.
