Sedimentation well PP DN500 – effective stormwater drainage

The DN500 sedimentation well is a solution designed for stormwater drainage systems from streets and urban areas, working with street inlets of class D400 (load capacity 40 tons). The well construction, combined with relieving rings, ensures effective water drainage, minimizing the loads acting on the well itself – they are transferred directly to the ground. This makes the system stable and resistant to damage.

Construction and application

The well is made of polypropylene (PP), which guarantees high chemical and mechanical resistance. Equipped with a smooth PP socket available in diameters DN160 or DN200, it allows easy connection to the existing sewage infrastructure. The high ring stiffness of the trunk pipe (SN8) is particularly important, ensuring stability under load. A version with a 150-liter sedimenter is available, allowing preliminary separation of contaminants before the water is fed into the sewage system. The total height of the well is 2000 mm, and the height of the sedimenter itself is 780 mm. The orange color ensures good visibility and identification.

Advantages and benefits for the installer and user

• Quick installation: The low weight of the elements facilitates transport and installation, eliminating the need for heavy equipment. This translates into saving time and labor costs.
• Economic solution: Narrow excavations and simple installation reduce investment costs.
• Durability and resistance: Polypropylene is characterized by high resistance to corrosion, abrasion and the action of aggressive chemical substances contained in wastewater and groundwater. External ribs protect the trunk pipe from mechanical damage.
• Flexibility: The possibility of easily making an additional connection in-situ – drilling a hole and mounting an insert – increases the functionality of the well.
• Stability: The construction transfers loads to the ground, minimizing the risk of damage to the well under the influence of vehicle traffic or changing weather conditions.
• Weather resistance: The material does not absorb water, is resistant to low temperatures and changes in soil volume related to freezing and thawing.
• Environmental safety: The material has no negative impact on the natural environment.
