Rainwater harvesting package (underground tank + equipment) TWINBLOC HAUSTECHNIK II 7000L (2x3500L) with rainwater control unit 1135006038

Comprehensive solution for collecting and utilizing rainwater

This package is a complete system for effectively collecting and utilizing rainwater, ideal for both installers and end-users. It provides an independent water source for domestic and economic purposes, such as flushing toilets, washing, cleaning, or watering the garden, reducing tap water consumption and lowering costs. The system is particularly recommended when the distance between the tank and the installation in the building is significant.

Design and components

The package consists of two interconnected TWINBLOC tanks with a total capacity of 7000 liters (2 x 3500 liters), made of durable polyethylene (PE). The design based on two cylinders provides exceptional stability and resistance to external loads – passenger vehicles can safely move above the tanks. The set also includes a rainwater center with a Combipress submersible pump equipped with a float, allowing automatic water intake from the tank. If rainwater is unavailable, the system automatically switches to the mains water supply, ensuring continuity of supply. Additionally, the package contains:

• DN 100 overflow siphon: Protects against tank overflow and access by small animals.
• 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 collector: Cleans rainwater from larger impurities before it enters the tank – the pre-filter removes leaves and branches, and the main filter retains smaller particles. Effectively protects the pump from damage. The filter is designed for a roof area of up to 350 m².
• Submersible pump with float: An efficient pump allows pumping water over significant distances between the tank and the building. The float controls the water level in the tank and automatically starts/stops the pump.

Advantages and benefits of use

• Economy: Reducing tap water consumption translates into lower water bills.
• Ecology: Using rainwater reduces the burden on the natural environment.
• Independence: Providing an alternative water source increases independence from the municipal water network.
• Automation: The rainwater center with pump and float ensures fully automatic system operation.
• Durability: Tanks made of polyethylene (PE) are resistant to corrosion and mechanical damage – the manufacturer guarantees 20 years on the tank and ROTH treatment plant, as well as 2 years on automation and mechanical parts.
• Safety: The overflow siphon protects against tank overflow and access by pests.
• Long lifespan: The Twinbloc design based on two cylinders provides exceptional stability even under heavy ground load.

The system is easy to install and operate, which will be appreciated by both professional installers and end-users. The system control unit should be placed in a utility room of the building to ensure optimal operating conditions.
