Rainwater harvesting package (underground tank + equipment) TWINBLOC HAUSTECHNIK II 10000L (2x5000L) with rainwater center 1135006039

Comprehensive rainwater harvesting solution

This package is a ready-made solution for the effective management of rainwater, ideal for both installers and end-users. The system is designed for use of water for domestic and economic purposes – flushing toilets, washing, cleaning or watering the garden. The package construction is designed for situations where the distance between the tank and the installation in the building is significant.

Construction and components

The package consists of two connected TWINBLOC tanks with a total capacity of 10 m³, made of durable polyethylene (PE). This construction ensures long-term reliability and corrosion resistance. The set also includes:

• DN 100 overflow siphon: Protects against access by small animals and drains excess water during heavy rainfall.
• Telescopic inspection chamber: Allows easy access to the tank for inspection and maintenance, and its cover can withstand a load of up to 200 kg.
• Ground filter: Effectively cleans rainwater from impurities, ensuring its quality suitable for further use. The pre-filter and main filter capture even small particles, and the basket collects larger debris. It is designed for roof areas up to 350 m².
• Rainwater control unit with Combipress submersible pump: Automatically draws water from the tank and delivers it to the internal water supply system. If rainwater is not available, the system automatically switches to the mains water supply, ensuring continuity of supply.

Advantages and benefits

• Efficiency: The submersible pump allows pumping water over long distances, increasing installation flexibility. The maximum lift height is 64 meters.
• Automation: A fully automated electronic controller ensures trouble-free operation of the system and minimizes user intervention.
• Savings: Using rainwater allows reducing the consumption of tap water, which translates into lower bills.
• Ecology: Rainwater management contributes to the protection of natural resources and reduces the burden on the municipal sewage system.
• Durability: The tank is covered by a 20-year warranty, and the automation and mechanical parts – a 2-year warranty, which proves the high quality of workmanship and reliability of the system.
• Versatility: Can be used in various conditions – both in new buildings and during the modernization of existing installations.

Construction and installation

TWINBLOC tanks are characterized by a cylindrical construction, which ensures optimal use of space and ease of installation. The system controller should be placed in a utility room of the building to ensure appropriate working conditions. The entire system has been designed so that its installation is as intuitive as possible and does not require specialized knowledge (although it is recommended by a qualified installer).
