Double-walled HDPE storage tanks

Double-walled HDPE Weholite storage tanks: safe storage of liquids

Double-walled HDPE Weholite storage tanks offer a reliable and durable solution for storing water, wastewater, and chemical liquids. These tanks are manufactured from a double-walled HDPE Weholite pipe and end faces, guaranteeing a 100% leak-free system. Thanks to their lightweight yet robust structure, they are suitable for both above-ground and underground installation and can be customized to meet the specific requirements of each project.

Production of HDPE storage tanks in Belgium

The production of these tanks takes place entirely in our own Belgian production facility, Collinet. Here, the tanks are custom-manufactured and equipped with all necessary connections and provisions, enabling quick and efficient installation. With their high chemical resistance and long service life, these storage tanks are the ideal choice for applications where environmental protection and safety are paramount.

What are the benefits of HDPE storage tanks?

HDPE (high-density polyethylene) offers numerous advantages compared to traditional materials such as

  • Excellent chemical resistance
  • Resistant to acids, bases and other aggressive substances
  • Lightweight and strong
  • Easy to transport and install without heavy lifting equipment
  • 100% recyclable
  • Sustainable and eco-friendly solution
  • Corrosion and UV resistant
  • Long-lasting performance without loss of quality
  • Flexible in design: custom-made for specific applications and requirements.

What are the applications of HDPE storage tanks?

The versatility of double-walled HDPE Weholite storage tanks makes them suitable for various applications:

  • Wastewater storage: safe buffering and transport of industrial and domestic wastewater.
  • Chemical storage: suitable for aggressive liquids such as acids and solvents.
  • Drinking water and food storage: meets strict standards for the safe storage of drinking water and liquid foods.
  • Rainwater management: used for buffering, infiltration, and reuse of rainwater
  • Industrial applications: storage of process water, fire water, and other liquids in production environments.

Certification of HDPE storage tanks

Our double-walled HDPE Weholite storage tanks comply with the strictest standards and inspections:

  • BENOR-certified (NBN EN 13476-2): quality assurance for water and sewerage systems.
  • Belgaqua Hydrocheck certificate: confirms safety for drinking water storage.
  • VLAREM II-approved: the only underground tanks in Belgium that comply with these stringent environmental regulations. This makes our storage tanks a unique and future-proof choice for companies looking to reduce their environmental impact and comply with the strictest regulatory requirements.
  • Permanent leak detection system: for continuous monitoring and maximum safety.
  • Level measurement and overfill protection: prevents overflow and guarantees optimal control.

FAQ

1. Are HDPE Weholite storage tanks suitable for the storage of chemical liquids?

Yes, double-walled HDPE Weholite storage tanks are extremely suitable for the storage of chemical liquids such as acids, bases, and solvents. The HDPE material offers high chemical resistance and is resistant to aggressive substances, without the risk of corrosion or degradation.
Thanks to their leak-free construction and long service life, these tanks provide a safe and durable solution for industrial applications.

Weholite storage tanks comply with strict Belgian and European standards. For example, they hold the BELGAQUA conformity certificate and VLAREM II certification, among others, confirming their suitability for the storage of both drinking water and hazardous chemicals.
In addition, they are produced according to standards such as NBN EN 13476-2 and equipped with safety features such as leak detection and overfill protection

Safety is ensured by several factors: a double-walled design, a 100% leak-proof construction, and integrated systems such as permanent leak detection and level measurement.
Furthermore, regular inspections and compliance with environmental legislation (such as VLAREM) contribute to the reliable and safe storage of hazardous substances.

HDPE offers significant advantages over traditional materials such as steel or concrete:

  • No corrosion or rust formation
  • High chemical resistance
  • Lightweight and quick installation
  • Long lifespan and low maintenance costs deschacht.eu, steptsl.com

Because of this, HDPE tanks are particularly suited for the long-term and safe storage of chemicals in industrial environments.
