Why Winter Is The Best Time Of Year To Clean Your Water Tank.

Winter’s cooler weather might not have you thinking about your water tank – but it should.

After all, many tanks are now sitting full, making this the ideal time to give your system a little attention. Whether your water comes from rain, bore, or both, your tank doesn’t take the season off.

Getting ahead with a winter clean will save you a lot of time and money, helping roll into summer with confidence.

1. A Full Tank is the Easiest to Clean

The winter season usually brings plenty of rain, keeping your tank nice and topped up. Thankfully, our advanced cleaning process actually works best when your tank is full, unlike other methods that require it to be emptied first.

This means:

• More of your water supply can be run through our filtration unit, leaving you with even more clean water.
• No need to waste water by dumping your supply before cleaning
• You’ll save money by avoiding the cost of expensive top-ups afterwards

So while the rain’s filling your tank, we can get it cleaned out properly. No waste, no refills, no extra costs.

2. Your Tank Collects More Than Just Rain Water

After the dry summer weather and autumn fallen leaves, winter rains bring more to your tank than just water. Your roof and gutters act like a big collection surface, and rain carries whatever it finds straight into your tank.

Common contaminants include:

• Roof cleaning chemicals
• Foliage
• Insects
• Birds nests
• Animal droppings
• Animals themselves (both dead and alive)
• Moss, dust, and dirt

If left unchecked, bacteria can grow in your water supply and pose serious health risks to anyone in the household. It’s easy to forget, but your roof can significantly influence the quality of your tank water.

A good preventative setup, combined with regular tank maintenance, is the best way to ensure your water stays safe to drink all year round.

Bonus: By keeping your gutters free of leaves and debris, you not only protect your water supply but also make the most of every drop of rain.

3. New Water + Dirty Tank = Muddy Mess

When rain is scarce and tanks are empty, ordering in water during summer is normal for many rural and tank-reliant households. While that’s usually harmless, it’s worth thinking about what might be lurking at the bottom of your tank before adding fresh water. A dirty tank can turn clean water into a bigger problem.

The force of the incoming water tends to disturb the sediment left settled at the bottom, which can contain all the contaminants we discussed earlier. All that sediment is now suspended in your new (and expensive) clean water.

This may cause:

• Murky brown colour or cloudiness in your water
• Changes in scent or taste
• Your filters may block up sooner than expected

Get Safe H2O to clean your water tank now and go into the dry season with a full and clean tank.

4. Dodge the Summer Stink! Increase in Temperature Can Create Bad Odours in your Tank

As summer rolls around, so do the higher temperatures. Warmer climates create ideal conditions for bacteria to grow, which can cause unpleasant smells and tastes in your water. Winter is the perfect time to stay ahead of water quality issues.

🚩 Warning: Smelling rotten eggs or sulphur in your tank? That’s a red flag for dangerous bacterial growth. It’s important to get on top of it with a thorough clean.

Leave it too long, and that harmless-looking buildup can turn into a contamination risk by summer. By removing built-up sediment ahead of time, you’re setting yourself up for fresh, clean water when it matters most, especially during the hotter months when demand is high.
