At Water Tank Lining, we specialise in the process of applying a specialist protective coating to the interior of a storage tank to prevent leaks, corrosion, and contamination. 

The lining creates a seamless, waterproof barrier, ensuring that potable water, industrial water, or wastewater remains safe and uncontaminated. 

Since unlined tanks are prone to rust, bacteria growth, and structural deterioration, professional water tank lining extends the tank’s lifespan and ensures compliance with UK water safety regulations.

Why Is Water Tank Lining Important?

Water tank lining is essential for maintaining water quality, preventing corrosion, and ensuring structural integrity. 

Over time, exposure to moisture, chemicals, and environmental conditions can cause rust, bacterial buildup, and cracks in tank walls. 

Lining the tank protects against these issues while ensuring compliance with WRAS (Water Regulations Advisory Scheme) and other UK industry standards. 

Since clean and safe water storage is crucial for health, safety, and environmental compliance, professional lining solutions prevent contamination and costly repairs.

How Long Does Water Tank Lining Last?

High-quality linings typically last 10 to 20 years, with some advanced coatings providing longer durability in harsh conditions. 

The lifespan of water tank lining depends on the type of coating, environmental conditions, and maintenance routine. 

Regular inspections, cleaning, and minor repairs help extend the lifespan, ensuring continued protection against leaks and contamination.

How Much Does Water Tank Lining Cost?

Prices can range from £500 for small tanks to £10,000+ for large industrial tanks. 

The cost of water tank lining depends on the tank size, lining material, surface preparation, and complexity of application. 

As lining prevents expensive repairs, environmental fines, and premature tank replacement, it is a cost-effective long-term investment. 

Since every tank has unique requirements, a detailed quote is provided after an assessment.

How Long Does the Water Tank Lining Process Take?

The application process for water tank lining usually takes one to five days, depending on the tank size, type of lining, and curing time. 

The process involves surface preparation, coating application, and drying/curing to ensure a strong, long-lasting bond. 

As some linings require multiple layers and specialist curing times, the total duration may vary. 

To minimise downtime for businesses, professional water tank lining services offer fast-drying solutions and flexible scheduling.

Is Water Tank Lining a Legal Requirement?

Water tank lining may be required under UK water safety and environmental regulations, particularly for potable (drinking) water storage. 

Tanks used for public water supply, food production, and industrial processes must comply with WRAS, DWI (Drinking Water Inspectorate), and HSE (Health & Safety Executive) standards. 

Ensuring that tanks are leak-proof and bacteria-resistant is essential for compliance, safety, and hygiene.

Can All Types of Tanks Be Relined?

Most concrete, steel, and GRP (Glass Reinforced Plastic) tanks can be relined, provided the structure is still sound. 

Lining is a cost-effective alternative to tank replacement, especially for large or difficult-to-access tanks.

Can an Old Water Tank Be Relined Instead of Replaced?

Water tank relining is a cost-effective alternative to full tank replacement, restoring damaged or ageing tanks to full functionality. 

If the tank’s structure is still sound, applying a new lining can prevent leaks, reinforce weak areas, and extend its service life without the expense of full replacement. 

A professional tank inspection determines whether relining is the best solution.

What Are the Benefits of Water Tank Lining?

Water tank lining provides a protective, waterproof barrier that prevents leaks, corrosion, and contamination, ensuring safe and long-term water storage.

Key benefits include:

• Prevents Leaks & Corrosion – Protects metal and concrete tanks from rust, chemical degradation, and water damage.
• Ensures Water Quality – Creates a hygienic, bacteria-resistant barrier for clean, safe water storage.
• Cost-Effective Alternative to Replacement – Restores existing tanks without the high costs of full replacement.
• Meets UK Regulatory Standards – Complies with WRAS, HSE, and industry regulations for potable and industrial water storage.
• Reduces Maintenance & Repair Costs – Extends the tank’s lifespan, minimising ongoing maintenance expenses.
• Compatible with Various Tank Types – Suitable for metal, concrete, plastic, and GRP tanks.
• Quick & Efficient Application – Relining can be completed in days, reducing operational downtime.

How Do I Know If My Water Tank Needs Relining?

If your tank shows signs of corrosion, leaks, cracks, discolouration, or bacterial growth, it may need relining. 

A professional inspection home’s can determine if relining is the best solution.

Can You Reline a Drinking Water Tank?

Potable water tanks can be relined using WRAS-approved, food-safe coatings that prevent contamination and ensure water remains clean and safe for consumption.

Does Water Tank Lining Affect Water Quality?

High-quality WRAS-certified linings are designed to be non-toxic and safe for drinking water, ensuring the stored water remains pure and uncontaminated.

Is Water Tank Lining Suitable for Concrete Tanks?

Concrete tanks can be lined using cementitious coatings, epoxy resins, or GRP linings, preventing leaks and strengthening structural integrity.

Can Underground Water Tanks Be Relined?

Underground tanks can be relined with chemical-resistant and waterproof coatings, preventing leaks and protecting against soil moisture infiltration.

Will Relining a Tank Reduce Downtime?

Professional tank relining can be completed in a few days, significantly reducing downtime compared to full tank replacement.

Can I Use My Tank Immediately After Relining?

Most tank linings require a curing period before the tank can be refilled. 

The timing of line curing can range from 24 hours to several days, depending on the lining material.
