Underground PEHD rainwater tank TWINBLOC 1500L 1135006122

Rainwater Harvesting – Reliable Twinbloc Underground Tank

Are you looking for an effective and durable solution for collecting rainwater? The Twinbloc underground tank with a capacity of 1500 liters is an ideal choice for both installers and end-users. Made of durable high-density polyethylene (HDPE), it ensures long-lasting and trouble-free operation. The construction based on two adjacent cylinders guarantees exceptional stability and resistance to loads, even in difficult ground conditions.

Tank Construction and Features

The Twinbloc tank is distinguished by a well-thought-out design that minimizes excavation depth – by up to 40% compared to traditional tanks of similar capacity. This translates to lower earthwork costs and faster installation. It is equipped with a number of practical elements that facilitate installation and use:

• Telescopic inspection chamber with a lid for up to 200 kg: allows easy access to the inside of the tank for inspection and cleaning. The height adjustment of the chamber allows it to be adapted to the installation depth.
• DN100 connection sockets: provide convenient connection to the rainwater drainage system.
• Overflow siphon: protects against overfilling the tank during heavy rainfall.
• Protection against small animals: prevents water contamination by unwanted guests.

Additionally, the tank can be connected with other Twinbloc models to create batteries of any capacity – simply use PVC pipes (available separately) and make holes in the appropriate places.

Application and Benefits

The Twinbloc tank is perfect for outdoor installations as an underground rainwater storage tank. The ability to load the inspection chamber lid up to 200 kg (or even 600 kg with an additional lid) allows for safe pedestrian and vehicle traffic over the tank. Importantly, the tank can also be placed in areas with a high groundwater level – up to half its height, which expands the range of possible locations. Thanks to this solution, rainwater can be effectively used for watering the garden, flushing toilets or washing, reducing water consumption from the water supply network and lowering bills. Investing in a rainwater harvesting system is also caring for the natural environment!
