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 […]
As China comprehensively advances the construction of Sponge Cities, rainwater harvesting and reuse systems have become critical infrastructure for green buildings and eco-industrial parks. Among these, Polypropylene (PP) module reuse systems are highly favored for their high efficiency and durability. At the core of this system’s longevity is the backwash piping—the “self-cleaning heart” whose technological […]

Published on: Global Water Infrastructure Portal • Industry Insights Category: Sustainable Urban Drainage Systems (SUDS) Rainwater harvesting and utilization has emerged as an increasingly prominent topic of global discussion in recent years. Water is intrinsically bound to our daily lives, regardless of whether a region is navigating a wet season or a drought. The core […]
Urban Environments Under “Fast Drainage” vs. “Slow Drainage” Modes: The Evolution Toward Resilient Sponge Cities Urbanization has long served as a primary engine driving global economic growth. However, rapid economic development has intensified the friction between resource availability and environmental sustainability—most visibly manifested in the stark contradiction between severe urban water scarcity and the massive […]
Zhengzhou Yayuan Technology offers high-quality valve boxes made of virgin HDPE/PE materials, featuring strong corrosion resistance, high load-bearing capacity, and long service life. With a full range of sizes and models, the products fit landscaping, municipal, agricultural, and sponge city projects. As a direct factory, Yayuan provides stable delivery, full technical support, and responsive after-sales service.

Zhengzhou Yayuan Technology Co., Ltd. recently shipped a batch of high-load bearing blue PP modules to Haikou, Hainan, to support local sponge city construction. These modules are specially designed for high-load scenarios including parking lots, plazas and municipal roads. With high structural strength, excellent bearing capacity, corrosion resistance and long service life, the modules offer over 95% void space for efficient rainwater harvesting, storage, infiltration, purification and reuse. The solution effectively relieves urban waterlogging, promotes water recycling and adapts well to Hainan’s high-temperature and high-humidity climate. As a national high-tech enterprise, Yayuan Technology provides reliable stormwater management solutions for sponge city projects across China.
