Water tank work has a reputation as a summer job. In practice, most relining projects carry on through the colder months without any trouble. So if you are wondering whether you can reline a water tank in winter, the short answer is yes.
There are a few things that change once the temperature drops, though. Here is what to expect, and why waiting until spring is not always the sensible choice.
What Changes When You Reline a Water Tank in Winter
The work itself happens inside a drained tank, which usually sits out of the way in a plant room or a tank room. That shelters it from the worst of the weather. Even so, cold air affects the job in a few ways.
Most lining systems have a minimum application temperature and a maximum humidity level set by the manufacturer. In cold conditions, a contractor may need to warm the space or run dehumidifiers before lining can begin. Curing also takes longer in the cold, so the tank may stay out of service a little longer than it would in July. None of this stops the work. It simply needs planning.
External and rooftop tanks need more thought. Icy walkways, frozen pipework and short daylight hours all affect how safely a team can work at height. A good contractor will factor this into the programme rather than discover it on the day.
Why It Can Pay to Reline a Water Tank in Winter
Cold weather is not only an obstacle. It brings a few genuine advantages.
- Quieter buildings. Schools, universities and many offices run at low occupancy over the festive period, which makes it far easier to take a tank offline.
- Shorter lead times. Summer diaries fill up quickly, so winter often means less waiting for a slot.
- Lower water temperatures. Stored water stays naturally cooler in winter, which helps with the temperature control set out in the HSE’s ACOP L8.
- Ready for spring. Getting the work done now means the tank is in good condition before demand picks up again.
The Risk of Waiting Until Spring
A tank that is already corroded or leaking will not improve over winter. Freezing conditions put extra strain on tanks, pipework and insulation, and a slow leak can become a burst in a cold snap.
Winter is also when a loss of supply hurts most. The same stored water often feeds heating and hot water systems. If your tank is showing signs that it needs relining, the season is rarely a good reason to put the job off.
Final Thoughts
You can reline a water tank in winter, as long as the contractor plans for the conditions and allows for longer curing times. The building, the access and the tank matter far more than the month on the calendar.
