Rainwater Storage Tanks

Rainwater collection systems for modern buildings and industrial facilities are of strategic importance in relieving urban drainage load and saving water. Unlike reinforced concrete systems, our GRP tanks offer a sealing guarantee and are fully resistant to acidic rain water.

• First Flush Separator Compatibility: Full integration with devices that separate the dirty load at the beginning of rain, storage quality is preserved.
• Opaque (Lightproof) Structure: Dark internal environment that prevents 100% algae growth through photosynthesis, water quality does not deteriorate.
• Calmed Inlet: The water inlet pipe is designed not to aerate the sediment at the bottom of the tank, ensuring clean water intake.
• Sediment-Protected Outlet: The water intake point is positioned 10-15 cm above the bottom, the sediment is not aspirated.
• Overflow Safety: The overflow pipe, which is the same or larger in diameter than the inlet pipe, is protected by a check valve that prevents pest entry.
• Capacity Planning Formula: Optimum volume calculation with the formula Vy = (A × Y × e) / 1000 (A: roof area, Y: annual precipitation, e: surface coefficient).
• YeS-TR Certificate Compliance: Full compliance with mandatory national green building certification criteria after 2026.
• UV Resistant Coating: Special Top-Coat coating resistant to sunlight for tanks to be used outdoors.
