Rainwater harvesting package (underground tank + equipment) TWINBLOC HAUSTECHNIK l 5000L with rainwater center 1135006033

Comprehensive solution for rainwater harvesting

This package is a ready-to-use solution for efficient rainwater harvesting, ideal for both installers and end-users. The system allows for storing rainwater, which can then be used for various purposes, reducing the consumption of drinking water and lowering costs. The package includes all the necessary components for the smooth operation of the installation, from the tank to the rainwater center.

Design and components

The package includes a TWINBLOC tank with a capacity of 5000 liters, made of durable polyethylene (PE). The characteristic cylindrical design, consisting of two interconnected chambers, provides exceptional stability and resistance to external loads – even to the passage of passenger cars. The tank is equipped with a siphon overflow DN 100 with protection against small animals and a telescopic inspection shaft with a lid that can withstand a load of up to 200 kg. The water intake system with a float guarantees the intake of clean water from the surface of the tank, minimizing the risk of sucking in sediment. Additionally, the package includes a calmed inlet and a flow filter designed for a roof area of up to 150 m².

The central part of the system is the rainwater center with a built-in ASPRI 15-4 pump and a water level indicator. The ASPRI 15-4 pump provides efficient water intake from the tank and its pumping into the building's internal water supply system. The maximum pump head is 42 meters, and the maximum flow rate is 3.5 m³/h. The pump suction range is 3 meters with a maximum suction pipe length of 15 meters.

Advantages and application

• Economical solution: Reduction of drinking water consumption and lower water bills.
• Versatility: Possibility of using the collected water for watering the garden, flushing toilets, washing or washing the car.
• Durable construction: The TWINBLOC tank is characterized by high resistance to external loads and corrosion.
• Safety: Protection against small animals and a flow filter ensure the cleanliness of the collected water.
• Completeness: The package includes all the necessary components for the smooth operation of the installation – from the tank to the pump and control.
• Easy installation: The system has been designed with simplicity of installation and use in mind.
• Automatic operation: The float in the water intake system ensures automatic replenishment of the tank with tap water in the event of a low level of rainwater.

This system is ideal for both new buildings, where it can be designed during the construction phase, and for existing homes – although adjustments to the water supply installation may be necessary. This is an investment in ecological solutions and savings for the future.
