Rainwater harvesting package (underground tank + equipment) HAUSTECHNIK ECO 3500L 1135008038

Economical and ecological solution for rainwater harvesting

This complete rainwater harvesting package is a proposal for anyone looking for an economical and ecological way to utilize natural resources. The system allows you to collect rainwater for various purposes, reducing water consumption from the mains and lowering bills. Rainwater, due to its softness and acidity, is ideal not only for watering the garden and flushing toilets, but also for washing and dishwashers.

The package includes a TWINBLOC tank with a capacity of 3500 liters, made of durable polyethylene (PE). A telescopic shaft DN 600 with a lid, a filter to protect against impurities, a calmed inlet ensuring clean water intake, and a Standard rainwater center with a float switch are also included – all for comfortable use and system reliability.

Construction and installation

The tank has a cylindrical shape and is made by blow molding. The high-density polyethylene (PE-HD) used guarantees durability and resistance to weather conditions. The tank weighs 150 kg and is 980 mm high. The possibility of connecting several tanks of the same capacity allows you to increase the storage volume – however, remember that only tanks with identical parameters can be connected.

Applications and benefits

Using rainwater is not only saving money but also caring for the environment. The average annual rainfall in Poland is 600 mm/m², which means that you can collect as much as 120 m³ of water annually from a roof with an area of 200 m²! Thanks to this system, you can reduce your demand for water from the water supply network by up to 45%. In addition, Roth offers a 20-year warranty on the tank and 2 years on automation and mechanical parts, which confirms the high quality of the product.
