Rainwater harvesting package (underground tank + equipment) TWINBLOC HAUSTECHNIK II 5000L with rainwater control system 1135006037

Comprehensive solution for collecting and utilizing rainwater

This package is a ready-made solution for the effective management of rainwater, designed for both home and professional installations. The system allows for the collection of rainwater, which can then be used for flushing toilets, washing, cleaning, or watering the garden – significantly reducing water consumption and lowering operating costs. The package combines a spacious underground tank with a rainwater center, providing an independent water source and user comfort.

Construction and components

The package includes a TWINBLOC tank with a capacity of 5000 liters, made of durable polyethylene (PE). The characteristic cylindrical construction, consisting of two interconnected chambers, provides exceptional stability and resistance to external loads – even from passenger cars. The tank is equipped with a DN 100 overflow siphon with protection against small animals and a telescopic inspection shaft with a durable cover (up to 200 kg). Additionally, the package includes a ground filter collecting for a roof area of up to 350 m², which effectively removes impurities from rainwater.

The central part of the system is the Combipress submersible pump with a float switch. The automatic water intake system from the tank guarantees a constant access to rainwater, and in case of its absence – automatically switches to the water supply from the water mains. Thanks to this, the system works reliably throughout the year. The set also includes a water intake system with a float switch, which ensures drawing clean water from the upper layers of the tank, minimizing the risk of sucking up sediment.

Advantages and benefits

• Economic savings: Reducing water consumption translates into lower water bills.
• Ecological solution: Using rainwater reduces the burden on the natural environment.
• Independence: Provides an independent water source for economic and domestic purposes.
• Automation: Automatic switching between rainwater and tap water ensures user comfort.
• Durable construction: The TWINBLOC tank is characterized by high stability and resistance to external loads.
• Easy installation and maintenance: The complete package facilitates installation, and the pre-filter minimizes the need for frequent tank cleaning.
• Long service life: The tank is covered by a 20-year warranty, and automation and mechanical parts – a 2-year warranty from the manufacturer ROTH.
• Versatility of applications: Ideal for both new buildings (designing installations during construction) and modernized facilities.

Applications

The TWINBLOC Haustechnik II package is perfect for:

• Single-family homes
• Multi-family buildings
• Gardens and green areas
• Commercial facilities (e.g. car washes)
• Installations requiring an independent water source for economic purposes

The system is particularly recommended in situations where the distance between the tank and the internal installation is significant – the efficient submersible pump provides adequate water pressure even over long distances.
