Identifying Asbestos Water Tanks
Before any removal work, it’s vital to confirm whether a water tank contains asbestos. Asbestos-cement tanks are typically grey or white, with a rough, fibrous surface. Visual inspections by a qualified professional, followed by sampling and laboratory testing, provide definitive identification. If suspect, an asbestos survey produces a detailed report outlining the presence and condition of the tank.
Removal Process Overview
Removing an asbestos water tank should not be attempted as a DIY project. The removal process involves several precise steps:
Assessment and Planning: A licensed contractor evaluates the condition and location of the tank, planning safety procedures and disposal routes in accordance with regulations.
Site Preparation: The surrounding area is sealed off with polythene sheets to prevent the spread of contamination. Warning signs are posted, and all personnel wear appropriate personal protective equipment (PPE), including respirators, coveralls, and gloves.
Tank Removal: The tank is dismantled carefully. Wetting the tank suppresses dust and fibre release. If space is limited, controlled breakage may be necessary, with the tank wrapped in thick polythene before and after breaking to prevent fibre escape.
Cleaning: After removal, the area is cleaned using HEPA-filtered vacuum equipment and damp rags to capture any missed fibres. Any insulation boards used to support the tank are treated similarly, and small debris is carefully contained.
Waste Disposal: All tank fragments and contaminated materials are double-bagged and taken to licensed hazardous waste facilities. An official consignment note confirms proper disposal in accordance with UK law.
Legal, Health, and Safety Considerations
UK law strictly prohibits unlicensed asbestos removal due to the health hazards involved. Exposure to asbestos fibres can cause lung cancer, mesothelioma, and asbestosis; therefore, handling and disposal must be conducted by certified contractors using HSE guidelines and compliant PPE. Failure to follow these procedures can result in legal penalties and health risks for both workers and occupants.
Cost Implications
Removal costs depend on tank size, access, and project complexity. For good access, professional removal prices typically range as follows:
| Tank Size | Good Access | Limited Access (Breakage Required) |
|---|---|---|
| Small (<½ m²) | £175 (+VAT) | £250 (+VAT) |
| Medium (½–1 m²) | £225 (+VAT) | £300 (+VAT) |
| Large (1–2 m²) | £275 (+VAT) | £350 (+VAT) |
Prices assume the tank is disconnected and empty; additional costs apply if plumbing work is required.
Why Professional Removal Matters
Professional removal offers multiple benefits:
All legal requirements and health protocols are met.
Risks from airborne asbestos fibres are minimized.
Waste is properly tracked and disposed of, with certification for peace of mind.
DIY removal should be avoided—not only because of health risks but also because legal disposal of asbestos waste is expensive and subject to strict regulatory oversight.
Conclusion
Asbestos water tank removal is a job for certified experts who can guarantee safety, legal compliance, and proper disposal of hazardous waste. Strict preparation, controlled techniques, thorough clean-up, and licensed disposal keep occupants, workers, and the environment safe from the long-term risks of asbestos contamination.
