There is a famous poem written in 1963 by the great Chinese literary figure Guo Moruo after he took a boat trip on Qiandao Lake: "Three thousand West Lakes lie here, and the mountains seem to lose their height." He was comparing the vast, 17.8 billion cubic meter reservoir to 3,000 of Hangzhou’s famous West Lakes.
Inspired by this poetic tribute to "the finest waters under heaven," a company was born on the shores of this emerald lake. For 30 years, Chun'an Qiandao Lake Renren Enterprise Co., Ltd. has been turning this natural gift into pure, safe drinking water through its flagship brand: Xizi Sanqian.
A Legacy of Quality and Innovation
Founded in 1996 in the scenic Qiandao Lake region of Zhejiang, China, Renren Enterprise has grown into a National High-Tech Enterprise and a Zhejiang Green Enterprise. The company holds 38 Chinese patents (including 7 invention patents) and was a principal drafting organization for the Packaged Natural Drinking Water group standard (T/ZJFIA 001—2019) in Zhejiang.
But perhaps the most impressive statistic is their impeccable safety record: A 100% pass rate in product sampling inspections for 30 consecutive years. The company rigorously adheres to ISO 9001, ISO 14001, ISO 22000, and ISO 45001 certifications, along with HACCP and social responsibility management systems. They are the only legitimate manufacturer in Chun'an with zero water-quality penalties or regulatory fines.
The Source: Deep, Living Water
Great water cannot be manufactured; it is a gift from nature. Xizi Sanqian draws its water from 20 meters below the surface near Mishan Island in Qiandao Lake. This deep, naturally flowing water maintains a stable temperature of around 12°C year-round. It is naturally filtered under high pressure, isolated from microbial and heavy-metal contamination, and contains dissolved oxygen between 7.5 to 9.68 mg/L.
The water is mildly alkaline and rich in essential minerals like potassium, sodium, calcium, magnesium, and metasilicic acid. To make it even safer for health-conscious consumers, the company uses advanced OSMO membrane separation technology to control the sodium content to approximately 3 mg/L (down from the natural ~10 mg/L). This makes it ideal for people with hypertension, heart conditions, or for mixing infant formula.
The Breakthrough: The Disposable Collapsible Water Container
For decades, the traditional 5-gallon water dispenser has been plagued by problems: secondary contamination, repeated heating, poor hygiene of reused barrels, and the risk of counterfeit water.
To tackle these issues, Xizi Sanqian spent 20 years and over 20 million RMB in R&D to develop their patented Disposable Collapsible Water Container. This innovation has won multiple awards, including the "Best Technological Innovation Award" in China's packaged water industry, and was featured on CCTV.
The magic lies in its simplicity: The container collapses automatically as water is dispensed. No air enters the container, keeping the water in a vacuum state and ensuring it stays as fresh as the moment it was filled.
Why It's a Game-Changer:
-
Safer: One-time use eliminates cleaning issues and the risk of fake water. The lightweight, transparent PET material prevents the use of illicit "black barrels" (recycled non-compliant plastic).
-
More Convenient: No deposits or returns. At just 10L and 100g, it's easy for anyone to lift. It works with existing electric kettles and dispensers using a simple stand and dispensing plug.
-
More Eco-Friendly: The container uses 70% less PET plastic than traditional barrels and collapses flat after use, drastically saving storage and shipping space.
The Complete Ecosystem: Water and Dispenser
To complement their water, Xizi Sanqian also produces a patented Secondary-Contamination-Free Instant Hot Water Dispenser (Patent No. ZL 2015 1 0720875.3). It features a fully enclosed water circuit and vacuum dispensing, heating water in just 3 seconds with no repeated boiling. It offers 5 temperature and 4 volume settings, and even supports AI voice control.
A Vision for the World
With the mission of "all for one and one for all," Renren Enterprise is committed to green development and quality. Their vision, "One Bucket for the World," reflects their goal to bring eco-friendly, healthy collapsible water-container products to households everywhere.
