Features That Make a Difference

1. Authentic Natural Look

One of the standout features of these tanks is their lifelike appearance. Models like the GRAF Rocky Wall Tank in Dark Granite are made using high-resolution molds and color blending techniques that mimic real stone textures. Each tank is unique in finish due to a special manufacturing process, offering a realistic look that doesn’t fade over time.

2. Durable & Weather-Resistant Materials

Crafted from high-quality UV-stable polyethylene or polypropylene, these tanks are built to endure harsh outdoor conditions. Whether you live in a hot, dry climate or experience heavy seasonal rain, your tank will maintain its structure and appearance for years. Many models also include frost protection.

3. Space-Saving Vertical Designs

Decorative tanks are typically designed with slim, vertical profiles, making them ideal for smaller yards, patios, or tight side spaces. You can collect a significant amount of rainwater—up to 500 liters in some models—without taking up much room.

4. Ready for Use

Most tanks in this collection include integrated brass tap connectors, wind protection systems, and secure inlet seals. Some also feature childproof locking mechanisms or lids for added safety. These thoughtful additions make setup quick and worry-free.

5. Eco-Friendly Production

Many of the decorative tanks are made using recycled or upcycled plastic, supporting sustainable production methods. Brands like GRAF integrate their proprietary Upcyclen material to reduce environmental impact while maintaining quality.

Ideal Uses and Applications

Decorative rainwater tanks are suitable for a variety of purposes:

• Garden Irrigation: Use collected rainwater to water plants, lawns, and vegetable gardens.
• Outdoor Cleaning: Fill watering cans or connect a hose for cleaning patios, decks, and outdoor furniture.
• Emergency Supply: Keep water on hand during dry spells, droughts, or local water restrictions.
• Landscaping Integration: Position the tank as a central element in your garden design to enhance the natural look of your space.

Installation and Setup

Installing a decorative rainwater tank is simple. Most models are designed for direct connection to your downspout using a rainwater diverter. The tank collects water during rainfall, and overflow can be directed back to your stormwater drain or into the ground. Tap installation is quick thanks to pre-threaded brass connectors.

Some helpful tips:

• Make sure the surface is level and solid before placing your tank.
• Position the tank close to a downspout for efficient collection.
• Use a filter or screen on your diverter to keep out debris and insects.
