Underground rainwater tank PEHD BASIC 5000L W-221

Rainwater tanks – an effective solution for home and garden

The BASIC 5000L PEHD underground rainwater tank is a practical solution for collecting rainwater, ideal for both domestic and garden applications. Made of durable high-density polyethylene (PEHD), the tank provides long-lasting and reliable operation. Its flat design makes installation easier, especially in areas with high groundwater levels or limited space.

Construction and application

The BASIC 5000L tank has been designed for ease of installation and versatility. It is equipped with a number of elements that ensure the full functionality of the rainwater retention system. It can be used for watering the garden, washing vehicles, flushing toilets or as a source of technical water. Thanks to its capacity of 5000 liters, it allows you to collect a significant amount of water, reducing water consumption and lowering costs.

Functionality and equipment

The kit includes all the necessary elements for its proper operation:

• Basket filter: prevents larger contaminants from entering the tank.
• Syphon with grate: provides drainage of water from the surface of the tank and additional filtration.
• Suction hose with float: allows water to be drawn from different levels of the tank, and the float protects the pump from running dry. Contains a mesh filter and a check valve led to the outside.
• 400mm inspection hatch: provides easy access to the inside of the tank for inspection and cleaning.

The tank design is designed to ensure its stability and resistance to ground loads. The PEHD material is resistant to corrosion, mechanical damage and UV radiation, guaranteeing a long product life. The tank can also be combined into larger retention systems, adapting the capacity to individual needs.
