Underground rainwater tank - GARDEN COMFORT 8400L set (CRISTALL TRIO 8400L tank + equipment with automatic submersible pump) W-278

Rainwater harvesting tank – a capacious solution for home and garden

This kit is a complete solution for efficient rainwater harvesting, ideal for both demanding home users and professional installers. It includes a spacious, underground CRISTALL TRIO tank with a capacity of 8400 liters, along with the necessary equipment for collecting and using the stored water. Using this system allows for a significant reduction in water consumption from the water supply, lower bills, and care for the environment.

Construction and application

The CRISTALL TRIO tank is made of durable PE-HD plastic, which guarantees its longevity and corrosion resistance. The three-segment construction makes it easy to transport and install, and the monolithic walls ensure a complete seal. The tank is perfect for collecting rainwater from roofs and paved surfaces. The collected water can be used for watering the garden, washing the car, flushing toilets, or powering irrigation systems. Additionally, the tank can serve as a sealed tank for wastewater. The set includes an external filter placed in the D400 manhole, which pre-cleans the water from impurities.

Comfort of use and efficiency

The kit also includes an automatic submersible pump with a connecting hose and a draw-off point with two quick couplings and shut-off valves. The automatic pump provides convenient water collection without the need for manual switching on and off. This makes the system fully functional immediately after installation. The usable capacity of the tank is about 7950 liters, which allows you to collect a significant amount of rainwater. The double-walled D600 cover ensures safe use and protects against access by children. The possibility of extending with a telescopic extension allows for precise adjustment of the cover height to the ground level.
