Rainwater harvesting package (underground tank + equipment) TWINBLOC HAUSTECHNIK l 7000L (2x3500L) with rainwater control unit 1135006034

Rainwater harvesting system Twinbloc Haustechnik 7000L

This complete package is an effective solution for collecting and utilizing rainwater, both for installers and end-users. The system allows reducing the consumption of drinking water, lowering costs and supporting ecological resource management. Application in households, gardens and public buildings.

Construction and components

The package consists of two cylindrical tanks connected to each other with a total capacity of 7000 liters (2x3500L), made of durable polyethylene (PE). This construction ensures stability and resistance to external loads, allowing installation below ground level with the possibility of passenger vehicle traffic. The set also includes:

• DN 100 overflow siphon: prevents the tank from overflowing and protects it from contamination. Additionally equipped with protection against access by small animals.
• Telescopic inspection chamber with a lid up to 200 kg: allows easy access to the tank for inspection and maintenance.
• Water intake system with float: ensures intake of clean water from the surface of the tank, minimizing the risk of sucking in sediment. The float keeps the water intake slightly below the surface, which prevents solid contaminants from entering.
• Calmed inlet: minimizes turbulence when pouring water into the tank.
• Flow filter: effectively cleans rainwater from leaves, branches and other contaminants, protecting the installation from damage. Filter adapted for a roof area of up to 150 m².
• Rainwater control unit with ASPRI 15-4 pump and level indicator: automatically draws water from the tank and delivers it to the building's internal water supply system (toilet, washing machine, cleaning). The ASPRI 15-4 pump provides adequate water pressure in the installation. The level indicator allows you to monitor the amount of water collected in real time.

Advantages and application

The Twinbloc Haustechnik system is an investment in the future that brings measurable benefits:

• Drinking water savings: using rainwater for economic purposes significantly reduces the consumption of tap water.
• Ecological solution: collecting and using rainwater contributes to the protection of the natural environment.
• Independence from the water supply network: the system provides access to water even in the event of a failure or restrictions in the supply of drinking water.
• Simple installation and maintenance: the system components are easy to install and require minimal maintenance.
• Durable construction: tanks made of high-quality polyethylene (PE) are resistant to corrosion and mechanical damage.
• Versatility: The system can be used both in new buildings (designing the installation during construction) and in existing facilities (modernization).

Thanks to the rainwater control unit, the system is fully automatic - even when the tank is emptied, the internal installation is automatically replenished with tap water, ensuring continuous operation.
