Asbestos Water Tank Removal in the UK

Asbestos was once heralded as a wonder material due to its strength, heat resistance, and affordability. From the mid-20th century until the 1980s, asbestos was used extensively in the UK, including in water tanks. However, with the discovery of its significant health risks, its use has been banned, and safe removal of asbestos-containing materials (ACMs) has become a priority. Among these materials, asbestos water tanks present a unique challenge, requiring careful handling and disposal to prevent exposure to harmful asbestos fibres.

Here we explore everything you need to know about asbestos water tank removal in the UK, including health risks, legal obligations, and the step-by-step process for safe removal.

What Is Asbestos and Why Was It Used in Water Tanks?

Asbestos refers to a group of naturally occurring silicate minerals known for their heat resistance, tensile strength, and insulating properties. These properties made asbestos a popular material in construction and manufacturing. In water tanks, asbestos cement was commonly used because it was lightweight, durable, and resistant to corrosion.

However, we now know that asbestos exposure can cause severe health issues, including asbestosis, lung cancer, and mesothelioma. The health risks arise when asbestos fibres are disturbed, releasing microscopic particles into the air that can be inhaled and lodged in the lungs.

The Risks of Asbestos in Water Tanks

  1. Degradation Over Time: Over decades, asbestos water tanks can deteriorate due to weathering, cracks, or general wear and tear. This degradation increases the risk of asbestos fibres becoming airborne, especially if the tank is disturbed during maintenance or removal.
  2. Health Hazards: Inhalation of asbestos fibres is the primary health concern. Once inhaled, these fibres can remain lodged in lung tissues for years, causing chronic inflammation and scarring that may lead to serious diseases. Even minimal exposure can pose a risk, making proper removal procedures essential.
  3. Environmental Impact: Improper disposal of asbestos water tanks can lead to contamination of soil and water, putting local ecosystems and communities at risk.

UK Regulations on Asbestos Water Tank Removal

The UK has strict regulations governing the handling and removal of asbestos-containing materials, outlined under the Control of Asbestos Regulations 2012. These regulations aim to protect workers and the public from exposure to asbestos fibres. Key points include:

  • Duty to Manage: If you own or manage a property, you are legally obligated to identify and manage asbestos risks. This includes ensuring that asbestos-containing water tanks are safely maintained or removed when necessary.
  • Licensed Work: While some non-licensed work with asbestos is permitted under specific circumstances, removal of asbestos water tanks often requires a licensed contractor, particularly if the material is in poor condition.
  • Disposal: Asbestos waste must be disposed of at licensed facilities. Dumping or mishandling asbestos is illegal and can result in severe penalties.

Identifying Asbestos Water Tanks

Before initiating any removal process, it’s crucial to determine whether your water tank contains asbestos. Asbestos water tanks are typically made from asbestos cement, a mixture of asbestos fibres and cement. They are often grey or white in appearance and have a rough, fibrous surface.

Professional Surveys

To confirm the presence of asbestos, a professional asbestos survey is recommended. These surveys involve:

  • Visual inspection
  • Sampling and laboratory testing
  • A detailed report outlining the presence and condition of asbestos

The Process of Removing Asbestos Water Tanks

Removing an asbestos water tank is not a DIY task. It involves strict safety protocols and the expertise of qualified professionals. Below is an overview of the process:

1. Assessment and Planning

  • A professional contractor conducts a risk assessment to evaluate the condition of the tank and the potential for fibre release.
  • A detailed plan is prepared, outlining removal procedures, safety measures, and disposal methods.

2. Preparation of the Site

  • The area around the tank is sealed off to prevent contamination.
  • Warning signs are posted to alert others of the presence of asbestos.
  • Workers don personal protective equipment (PPE), including respirators, disposable coveralls, and gloves.

3. Removal

  • The tank is carefully dismantled to minimise fibre release. This may involve wetting the material to suppress dust.
  • Pieces of the tank are double-bagged or wrapped in polythene sheeting and securely sealed.

4. Cleaning the Area

The site is thoroughly cleaned using specialised equipment, such as HEPA-filtered vacuums, to remove any residual asbestos fibres.

5. Disposal

The removed tank is transported to a licensed asbestos waste disposal facility. Contractors provide a waste consignment note as proof of proper disposal.

Costs of Asbestos Water Tank Removal

The cost of removing an asbestos water tank in the UK varies depending on several factors:

  • Size of the Tank: Larger tanks require more time and resources to remove.
  • Condition of the Tank: Tanks in poor condition require more precautions and may incur higher costs.
  • Accessibility: If the tank is located in a hard-to-reach area, additional equipment or labor may be needed.

On average, professional removal can range from £400 to £800, including disposal. It’s important to obtain quotes from multiple licensed contractors to ensure competitive pricing.

Choosing a Licensed Contractor

Selecting a qualified contractor is essential for ensuring the safe and legal removal of your asbestos water tank. Look for contractors who:

  • Hold a license from the Health and Safety Executive (HSE).
  • Have experience in asbestos removal and disposal.
  • Provide clear documentation, including a risk assessment, method statement, and waste consignment note.

You can search for licensed contractors on the HSE’s official website.

DIY Removal: Is It Ever an Option?

While DIY removal of asbestos water tanks is legal under certain conditions (if the material is in good condition and appropriate precautions are taken), it is highly discouraged. The risks associated with improper handling far outweigh any cost savings.

If you choose to proceed with DIY removal, you must:

  • Use appropriate PPE.
  • Wet the tank to suppress dust.
  • Follow strict guidelines for sealing and disposing of asbestos waste.
  • Consult local authorities for disposal locations.

However, to ensure safety and compliance with UK regulations, hiring a professional is strongly recommended.

Asbestos Water Tanks and Property Sales

If you are selling a property that contains an asbestos water tank, you are legally required to disclose this information to potential buyers. A professional asbestos survey can help provide documentation, reassuring buyers that the risks are being managed appropriately.

Conclusion

Asbestos water tank removal is a complex process that requires careful planning, professional expertise, and strict adherence to UK regulations. The health risks posed by asbestos fibres make safe removal essential, not only for your well-being but also for the safety of those around you.

By hiring licensed contractors and following established protocols, you can ensure that the removal process is both safe and compliant. Whether you are managing a residential property or a commercial site, addressing asbestos risks promptly is a crucial step in protecting health and maintaining legal compliance.
