Cold water storage tanks play a critical role in supplying potable water to various commercial and residential properties, such as hotels, schools, hospitals, and apartment buildings, among others. Ensuring water quality in these tanks is crucial for maintaining public health and safety, particularly to avert the risk of waterborne diseases such as Legionnaire’s Disease.

This severe respiratory illness is caused by the Legionella bacteria, which can thrive in water systems if appropriate preventative measures are not in place. As a result, maintaining the cleanliness and safety of cold water storage tanks is not only a matter of promoting public health but can also be a legal requirement in many jurisdictions.

In this comprehensive guide, we will delve into the vital aspects of cold water storage tank maintenance, including regular inspections, cleaning, disinfection procedures, and design considerations. By adopting meticulous maintenance practices, businesses and organisations can protect the health of their occupants, clients, or customers and ensure compliance with relevant regulations.

Additionally, we will highlight the benefits of partnering with experienced professionals like ATM Tanks for your tank maintenance needs.

Common Tank Liner Materials and Their Characteristics

To make an informed decision regarding the right tank liner material for your specific storage needs, it’s essential to have an understanding of the common liner materials and their characteristics. The following materials are commonly used for tank liners:

  • EPDM (Ethylene Propylene Diene Monomer): EPDM is a versatile synthetic rubber material with excellent resistance to UV rays, ozone, and weathering. It offers moderate resistance to chemicals and is predominantly used in water storage tanks and wastewater treatment tanks.
  • PVC (Polyvinyl Chloride): PVC is a widely used liner material offering resistance to chemicals, abrasion, punctures, and UV damage. PVC liners are available in an array of formulations, such as potable water grade, fuel-resistant, and chemical-resistant types, catering to diverse storage requirements.
  • RPE (Reinforced Polyethylene): RPE liners are made by combining layers of polyethylene film with layers of reinforcement mesh, providing enhanced durability and resistance to punctures and tearing. These liners are ideal for tanks storing non-aggressive chemicals, wastewater, and irrigation water.

XR Geomembranes: XR Geomembranes are designed to offer extreme chemical and UV resistance, as well as high strength and durability. These materials can withstand harsh environments and are suitable for long-term storage of aggressive chemicals and other materials.

Factors to Consider When Choosing a Tank Liner Material

Having examined the common liner materials and their characteristics, there are several key factors to consider when deciding on the appropriate liner material for your storage tank:

  • Stored Contents: Most importantly, consider the type of substance your tank is intended to store. A liner must be chemically compatible with the stored material and capable of withstanding any corrosive properties.
  • Temperature and Weather Conditions: Environmental factors, such as temperature variations and weather conditions, can impact the performance of a liner material. Ensure the chosen liner can withstand the conditions specific to the tank’s location.
  • Regulatory Compliance: Depending on the stored material and industry, certain regulations and standards must be adhered to in the choice and use of tank liners. Select a liner material that meets these requirements.
  • Tank Configuration: The size, shape, and any internal features of the tank may influence the liner selection, as some liners are more flexible and easier to install in intricate or large tank configurations.

The Role of Expert Consultation and Support

Navigating the selection process for the appropriate tank liner material can be a complex task. Collaborating with an experienced provider like ATM Tanks can support you in making a well-informed decision – one that best aligns with the specific needs of your storage tank.
