Why Backwashing Pipe Systems Are Crucial for PP Module Rainwater Retention Tanks in Sponge City Construction

In Sponge City construction, installing a backwashing pipe system in Polypropylene (PP) modular rainwater retention tanks is essential for ensuring long-term operational efficiency. Key reasons include: 1. Preventing Sedimentation and Clogging Stormwater runoff carries sand, silt, suspended solids, and other impurities into the retention tank. Over time, accumulated sediment reduces the tank’s effective storage capacity […]
