How Long Does Tank Relining Last?

Published: June 5, 2025

If your water tank is starting to show signs of wear such as corrosion, leaks, or flaking internal coatings then relining can be a smart, cost-effective alternative to replacement. But a question we often get asked is: how long does tank relining actually last?

The answer depends on a few key factors, including the condition of the existing tank, the type of lining system used, and how well it’s maintained. Let’s break it down.

ES Water Solutions prides itself on offering a 15 year guarantee on all Water Tank Relining projects. We use our own WRAS approved solvent-free polyurethane coating which is anti-corrosive for use in water tanks, pipelines, pipe fittings and associated equipment.

What Affects the Lifespan of a Relined Tank?

Tank Condition Before Relining

If the structure of the tank is sound and the corrosion hasn’t caused significant metal loss, relining can provide a solid, long-term solution. Severely degraded tanks might still be suitable for relining, but may require more intensive preparation or reinforcement. We always undertakes a site visit to make sure water tank relining is right for your tank.

The Lining System Used

Different coatings have different durability levels:

Epoxy coatings typically last 10–15 years and are common for clean water storage.
Polyurethane coating can offer greater flexibility and durability, lasting 20+ years in the right conditions.
Cementitious coatings are often used in concrete tanks and also provide long-term protection when properly maintained.

We match the right material to the tank’s usage, ensuring optimal longevity.

Preparation is Key

Like any project, preparation is key to ensuring a successful tank relining project. Before any work begins we ensure that the tank is correctly emptied, taken offline and properly cleaned to ensure the long lifespan of the application. Not preparing the tank correctly can lead to reduced adhesion, and compromise the lining’s lifespan.

Regular Maintenance

All because your tank is freshly relined, that doesn’t mean it shouldn’t be maintained. To guarantee the relining application remains as good as it can be, regular maintenance must be performed. This is especially important to avoid contamination and diseases such as Legionella.

We manage a large residential block and recently reached out to Echo to quote to reline two water tanks that were failing. An absolute fantastic service all round. A quote was received within a day or so. Works were booked in and communication was excellent. We were really impressed with the engineers on the day. They communicated well on the day in terms of the plan of action. Once the work was complete, they ensured all areas were left clean and tidy. A follow up report post works was sent very soon after the works.

We look forward to working with Echo again. If you need honest, reliable contractors who will get the job done and to a high a standard, don't hesitate to get in touch with them.

Thank you.

I contacted Echo Square on behalf of a client of mine who urgently needed her Victorian underground Cistern re lined. The work was quoted for promptly and the work carried out to a high standard by the engineers who were courteous and friendly despite their long drive to site. My client was very impressed and so grateful to have her Cistern back in working order. I would highly recommend this company and will most definitely approach them again should I have another client with tank issues in the future. 5 star service!

Echo Square Services team assisted in helping with the refurbishment of two very difficult to access steel water tanks located at a VIP client’s head office.

Their team did a fantastic job.

I was especially impressed by the comprehensive photo report at the end.

Highly recommend!

Having used other companies in the past I can wholeheartedly say that our dealings with Nationwide Tank Relining have been a breath of fresh air. We have had tanks relined, water hygiene assessments and floor coatings. All work was carried out in a timely manner and the quality of work has each and every time been exemplary. My bosses are thrilled with my decision to switch to Nationwide Tank Relining and a tank that was relined 10 years ago by them still looks good as new internally, and the money we've saved from choosing the right supplier has proven to be a very smart business move. Highly recommended!
