Hengshui City Yike Composite Materials Co., Ltd. has been a trusted manufacturer of composite water storage solutions since 2009, specializing in high-quality GRP tanks. Our Double-Walled GRP Modular Water Tank is designed to meet the growing demand for efficient rainwater harvesting and agricultural water storage. With capacities ranging from 1,000 to 10,000 liters, this tank combines the strength of fiberglass with the flexibility of modular construction, offering a durable, corrosion-resistant, and cost-effective solution for farms, gardens, and rural communities. Whether you need to capture rainwater for irrigation or store water for livestock, our tank delivers reliable performance year after year.
The modular design allows for easy transportation and on-site assembly, even in remote locations. Each panel is precision-molded using advanced GRP technology, ensuring consistent thickness and structural integrity. The double-walled construction provides an extra layer of insulation, reducing temperature fluctuations and minimizing algae growth—a critical advantage for agricultural water quality. Our tanks are built to withstand harsh weather conditions, including UV exposure, freezing temperatures, and heavy loads, making them suitable for both above-ground and partially buried installations.
Key Features & Technical Specifications
- Double-Walled Construction: Provides enhanced insulation and structural strength, reducing heat loss and preventing contamination.
- Modular Panel System: Panels are interlocking and bolted together, allowing for unlimited expansion and customization of shape and size.
- Corrosion & UV Resistant: GRP material is non-corrosive, rot-proof, and resistant to UV radiation, ensuring a long service life without maintenance.
- Food-Grade Inner Liner: Optional inner coating ensures safe storage of potable water (upon request).
- Lightweight & Easy to Transport: Panels are lightweight compared to concrete or steel tanks, reducing shipping costs and installation effort.
- Versatile Applications: Ideal for rainwater harvesting, agricultural irrigation, livestock watering, fire protection, and emergency water storage.
- Customizable Accessories: Inlet/outlet fittings, overflow pipes, manholes, and level indicators can be added as needed.

Why choose our Double-Walled GRP Modular Tank? The modular design not only simplifies transportation and installation but also allows you to start with a small capacity and expand later as your needs grow. The double-walled structure provides superior thermal insulation compared to single-walled tanks, keeping water cooler in summer and preventing freezing in winter. This is especially important for agricultural applications where water temperature can affect crop health and livestock hydration. Additionally, the smooth inner surface of GRP panels prevents sediment buildup and makes cleaning easy, reducing maintenance time and costs.
For rainwater harvesting, our tank can be integrated with downspout diverters, first-flush devices, and filtration systems to ensure clean water storage. The UV-stabilized GRP material will not degrade under direct sunlight, and the tank can be painted or covered with an insulating jacket (optional) for added protection. With a lifespan exceeding 20 years, this tank offers an excellent return on investment for farmers and property owners who want a sustainable water management solution.

Frequently Asked Questions
-
Q: How long does it take to assemble the tank?
A: Assembly time depends on tank size and crew experience. Typically, a 5,000L tank can be assembled by 2–3 people in 4–6 hours. Detailed instructions and video guides are provided. -
Q: Can the tank be used for drinking water?
A: Yes, if you request the optional food-grade inner liner and proper cleaning. Standard tanks are suitable for rainwater, irrigation, and non-potable uses. For potable water, please specify your requirements. -
Q: Is the tank resistant to earthquakes or ground movement?
A: The modular GRP panels are flexible and can withstand minor ground movements better than rigid concrete tanks. For seismic zones, we recommend additional anchoring or a flexible foundation. -
Q: What maintenance is required?
A: Minimal. Periodically check for debris in the inlet filters, inspect seals and bolts, and clean the interior if sediment accumulates. The GRP material does not rust or corrode. -
Q: Can I expand the tank after installation?
A: Yes. Since the tank is modular, you can add extra panels to increase capacity. However, the foundation may need to be extended accordingly. Consult our technical team for details. -
Q: What is the warranty period?
A: We offer a standard 5-year warranty against manufacturing defects. Extended warranty options are available upon request. -
Q: How do I choose the right capacity?
A: Consider your daily water usage, roof catchment area (for rainwater), and local rainfall patterns. For agricultural use, a general guideline is 10–20 liters per square meter of irrigated area per day. Contact us for a customized calculation. -
Q: What accessories are available?
A: We offer a range of accessories including inlet/outlet bulkhead fittings, overflow pipes, ball valves, manhole covers, level indicators, and first-flush diverters for rainwater systems.
