Underground PEHD rainwater tank TWINBLOC 5000 l 1135005426

Rainwater harvesting with efficiency and durability

This TWINBLOC underground rainwater tank with a capacity of 5000 liters is an ideal solution for households and businesses looking for an effective way to collect and use rainwater. Made of high-quality high-density polyethylene (HDPE), it provides reliability and durability, and its design allows for a wide range of applications. The tank is monolithic, meaning it is seamless – this minimizes the risk of leaks and ensures greater strength.

Construction and functionality for demanding applications

The TWINBLOC tank is distinguished by a unique design based on two cylinders placed side by side. This innovative construction guarantees exceptional stability, even under soil load or when passenger vehicles pass over it. This allows the tank to be installed in areas exposed to traffic without fear of damage. Importantly, the tank can also be placed in areas with a high water table – a solution for difficult terrain conditions. The set includes all the necessary elements for proper operation: a telescopic inspection shaft with a durable lid (up to 200 kg), DN100 connection fittings, an overflow siphon and protection against small animals.

Advantages for the user and installer

• Durability and resistance: Made of high-grade HDPE, resistant to corrosion and mechanical damage. This material is 100% recyclable, which emphasizes the ecological character of the product.
• Versatility: Possibility of installation in various ground conditions, including areas with a high water table.
• Easy installation: Simple construction facilitates and speeds up installation, which translates into saving time and labor costs. The adjustable height of the inspection shaft adapts to the installation depth.

• Safety: Equipped with an overflow siphon to prevent overfilling and protection against small animals.
• Long warranty: The manufacturer offers as much as 20 years warranty on the tank, which proves its high quality and reliability.

Let's remember that the average annual rainfall in Poland is about 600 mm/m2, which means that you can collect up to 120 m3 of rainwater annually from a roof with an area of 200 m2! This is a significant amount of water that can be used effectively.
