Protecting Your Rainwater Tanks During the Winter

Rainwater tanks are excellent sources of water during the warmer seasons because they recycle and store supposedly ‘used’ water from rainfall for your gardening needs. Come winter season in Western Australia, however, rainwater tanks may require extra protection to keep them from corroding or malfunctioning in the summer.

Here are four ways you can preserve the quality of your rainwater tanks even during the winter:

Empty Your Tank

Before the winter comes, use up whatever water is left in the tank for your garden. Unless you are certain the rainwater tank is installed in a manner to prevent freezing, emptying it is a good way to prevent damage. Although Western Australia is warmer than other regions of the country, it is best to stay safe. If you leave large amounts of liquids in a rainwater tank during the winter season, water could freeze and may potentially break your tank.

Invest in Proper Tank Covers

If you leave a flat cover on your tank during the winter, a gradual build-up of ice may lower the temperature of the water. Sloping water tank covers, on the other hand, prevent ice formation above the tank while keeping the water inside warmer.

Ensure Adequate Tank Insulation

If you want to keep water within the rainwater tank in the winter, insulating material that protects the tank from the cold helps maintain a steady temperature. Instead of heating from the bottom, attach the insulating material onto the sides of the tank to prevent warmth from escaping.

Protect Your Pipes and Valves

Lower temperatures may cause pipes or valves to split or shatter. To prevent this, bury your pipes underground as this will protect them from surface frost.

Water is essential to your garden. Giving your rainwater tanks the care they need during the winter ultimately helps them to perform better in the warmer weather.
