Construction and application

This underground tank is designed for storing domestic, sanitary, municipal sewage and rainwater. The MAX extension, with DN160 inlets, allows for convenient connection of the drainage system.

• Durable construction: Made of high-density polyethylene (PE-HD) provides resistance to mechanical damage, corrosion and weathering.
• Versatility: Can be used for various purposes - from collecting rainwater for garden irrigation to storing sanitary sewage.
• Easy installation: The tank components are factory-matched, which significantly speeds up and simplifies the installation process.
• Expandability: The MAX telescopic extension allows for height adjustment and 360° rotation, and is prepared for mounting additional elements, such as a pump or Aqua-Control+ controller.
• Safety: The tank is sealed, preventing leaks and environmental pollution.
• Long-lasting operation: The material is 100% recyclable.

Construction features

The Carat tank is characterized by a monolithic PE-HD body construction, which guarantees its tightness and durability. The MAX extension provides easy access to the inlets and allows you to adjust the tank height to individual needs. The lack of a cover in the set allows for flexible adaptation of the solution to specific installation conditions - you can purchase an appropriate cover adapted for pedestrian traffic or a B125 cast iron cover for vehicular traffic. DN160 inlets facilitate the connection of drain pipes.
