hengzhou Yayuan Technology’s PP Modules Shipped for Pangdonglai Sponge‑City Project, Helping Zhengzhou Build a “Breathable” Green Commercial Benchmark

Zhengzhou, October 13, 2026 — Yesterday afternoon, at the manufacturing base of Zhengzhou Yayuan Rainwater Utilization Technology Co., Ltd. (hereinafter referred to as Zhengzhou Yayuan Technology), a batch of high‑load PP rainwater harvesting modules were fully loaded onto trucks and officially dispatched to the construction site of the Pangdonglai Zhengzhou Project. This marks the official commencement of on‑site construction for Pangdonglai’s sponge‑city rainwater collection project. With reliable product quality and professional technical services, Zhengzhou Yayuan Technology will inject green “sponge‑city” momentum into this highly‑anticipated provincial commercial benchmark project.

pecially Developed for High‑Load Scenarios with Industry‑Leading Performance

The PP modules delivered to the Pangdonglai site are core products independently developed by Zhengzhou Yayuan Technology for heavy‑load applications including large‑scale commercial complexes, municipal plazas and underground parking lots. Manufactured via one‑step injection moulding from polypropylene (PP), the modules deliver outstanding structural rigidity and load‑bearing capacity. Boasting a void ratio of 90%‑95% and a single‑module water‑storage capacity of 200 L, they can withstand surface loads of 40‑70 tons per square metre, fully meeting stringent requirements for vehicle traffic and pavement laying atop commercial premises.

ompared with conventional concrete rainwater tanks, Yayuan PP modules adopt a split modular design for flexible on‑site assembly, enabling “excavation and backfilling completed within one day”. This greatly shortens construction timelines while lowering overall project costs. Thanks to the hollow structure, the land above the underground tank remains available for green spaces, parking lots or public plazas without occupying valuable ground‑level space, which perfectly aligns with the intensive‑development concept of the Pangdonglai project: “urban park above ground, commercial facilities underground”.

Serving a Local Benchmark and Demonstrating the Responsibility of “Henan‑Made” Products

As Pangdonglai’s first outlet outside Xuchang and Xinxiang, the Zhengzhou project has drawn high expectations from consumers across Henan since its planning stage. Located on the east plaza of Zhengzhou East High‑Speed‑Rail Station, the project adopts an innovative layout integrating an over‑ground urban park with underground commerce, aiming to build a hub‑oriented commercial complex for shopping, dining and cultural‑tourism services. By participating in the sponge‑city rainwater‑harvesting system, Zhengzhou Yayuan Technology will deploy underground PP‑module tanks to collect, regulate and recycle rainwater for landscape irrigation and road washing, supporting the project’s low‑carbon and green operation goals.

Pangdonglai is a shining business card for Henan’s commerce. We feel a strong sense of responsibility to supply sponge‑city products and technical support for such a landmark project,” said Jia Xiaojing, Project Manager at Zhengzhou Yayuan Technology. “We have rolled out dedicated production and delivery schedules for this project to guarantee on‑time, high‑quality supply and fully support construction progress.”
