Yayuan Technology’s frontline team worked overtime in the rain to complete the shipment of high-performance PP modules and full rainwater harvesting systems for the Qinhuangdao project, adhering to strict quality standards and boosting local sponge city development.
Zhengzhou Yayuan Technology: Phase I of 600m³ Sponge City Rainwater Harvesting & Reuse System Project at BYD Zhengzhou Airport Zone Successfully Completed Zhengzhou, Sep 21, 2026 — Recently, Zhengzhou Yayuan Rainwater Utilization Technology Co., Ltd. (referred to as Zhengzhou Yayuan Technology) announced the milestone progress of its 600 cubic meters sponge city rainwater harvesting and […]
Amid the accelerated integration of green development and smart agriculture, Zhengzhou Yayuan Technology (Zhengzhou Yayuan Rainwater Utilization Technology Co., Ltd.) has completed its strategic upgrade from a single‑supplier of rainwater harvesting systems to a comprehensive solution provider for “Sponge City + Intelligent Irrigation”. Adhering to the philosophy of deepening traditional industries and refining new tracks, […]
Application Scenarios: Sponge City rainwater purification, rural domestic sewage treatment (widely used vertical subsurface flow ecological filtration system) Working Principle Wastewater and rainwater infiltrate vertically from top to bottom. The system achieves water purification through three core mechanisms: filter media biofilm attachment, microbial degradation, and plant root absorption. Layered anaerobic, anoxic, and aerobic zones are […]
We supply heavy-duty irrigation valve boxes in 6 inch, 10 inch, 12 inch and 14 inch sizes. UV-resistant, waterproof and durable underground sprinkler valve enclosures for residential, commercial and agricultural irrigation systems.
This case study presents the sponge city renovation project at Kaifeng Railway Station Square. Adopting high-strength PP rainwater harvesting modules, the system effectively eliminates urban ponding and waterlogging, stores rainwater resources, and supports green, sustainable urban transportation hub construction.
A valve box is an enclosure designed to protect quick couplers, solenoid valves, stop valves, ball valves, gate valves, handheld pressure reducing valves and other valve components. The valve box serves as a protective housing for valves, quick couplers, solenoid valves, handheld pressure reducing valves and related fittings. It is widely used in agricultural irrigation […]
Zhengzhou Yayuan Technology has successfully shipped a batch of 14-inch square valve boxes to Xinjiang aboard a 17.5-meter trailer departing from Zhengzhou Airport Economy Zone. Made from high-strength UV-resistant plastic, these valve boxes offer a lightweight, durable, and easy-to-install alternative to traditional brick valve pits, with a grass-green finish that blends seamlessly into park and garden landscapes. Designed for large manual valves, pressure reducing valves, and filtration equipment, the 14-inch model is well suited to Xinjiang’s large irrigation districts and municipal infrastructure needs. This shipment reinforces Yayuan Technology’s growing presence in western China, following the establishment of an office in Aksu Prefecture, and underscores the company’s role as a National High-Tech Enterprise supporting sponge city and water-saving initiatives across the Belt and Road region.
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 […]
On June 6, a batch of high-load PP rainwater harvesting modules manufactured by Zhengzhou Yayuan Rainwater Utilization Technology Co., Ltd. (referred to as Zhengzhou Yayuan Technology) departed from the company’s Zhengzhou production base and headed for Zhoushan City, Zhejiang Province. The products will be deployed in local rainwater collection and storage projects for the sponge […]
