Rainwater tank – a complete solution for retention and water use

This kit is a comprehensive solution for collecting and utilizing rainwater, ideal for both households and professional installers. It includes a durable Cristall Trio tank with a capacity of 8400 liters, along with the necessary equipment for efficient collection and use of the stored water. This system allows for a significant reduction in drinking water consumption, lower costs, and environmental protection.

Construction and equipment

The kit is based on the Cristall Trio tank, made of high-quality high-density polyethylene (HDPE), which guarantees its durability and corrosion resistance. The three-module design facilitates transport and assembly, and the monolithic walls ensure complete tightness. The kit also includes:

• Telescopic extension D600 with adjustable height (470-950 mm) – allows adaptation to terrain conditions and an aesthetic appearance.
• Double-sided cover – ensures safe use and resistance to loads.
• Rainwater control unit – automates the process of water collection and replenishment, ensuring optimal system performance.
• System passage through the wall – allows connection of the installation inside the building.
• Suction hose with filter, check valve and float – ensures intake of clean water from the surface of the tank.
• Float with cable – controls the water level in the tank.
• External filter placed in the D400 manhole – pre-cleans the water from impurities.

Advantages and applications

This system offers a number of benefits for both end users and installers:

• Water saving: The possibility of saving up to 50% of drinking water consumption by using rainwater for watering the garden, washing the car or flushing toilets.
• Ecology: Reducing the load on the water supply network and protecting natural resources.
• Maintenance-free: The system is designed to minimize the need for maintenance (with the exception of regular filter cleaning).
• Versatility: The tank can also be used as a sealed tank for wastewater (septic tank).
• Easy installation: The modular design facilitates the transport and installation of the tank, even in difficult ground conditions (up to 50 cm of groundwater level).
• Durability: Made of high-quality materials resistant to mechanical damage and weather conditions.

Thanks to this, the tank will work in any garden, providing independence from the municipal water supply and contributing to environmental protection. Installers will appreciate the ease of installation and the reliability of the system, which translates into customer satisfaction and work efficiency.
