Why Cleaning Your Rainwater Tank is Important?

Rainwater tank maintenance is essential and all rainwater tank system manufacturers and installers should provide some advice on this when you move into your new home, even if it’s via your new home builder or previous owner This is especially important when you’re using this system in combination with the main water supply. When you keep your rainwater tank hygienic, you’re playing a key role in safeguarding the wellbeing of your home and business.

Regular cleaning is key because sediment, debris and other outdoor elements can easily build over time. Which in turn allows for the rapid spread of diseases or other harmful bacteria. Not only that, this sediment at the bottom of the tank system turns into a thick layer of “liquid sand paper” which can break any pump system and cause it to fail

What hazards come from not cleaning water tanks?

When rainwater flows from the roof and into the tank it picks up contaminants. From debris, dirt and other organic matter. It doesn’t matter how clean you keep your gutters and stormwater system, the best thing that can happen from such maintenance is slowing down the build up of sludge and mud in the tank.

Many of these hazards are responsible for water contamination, pump system problems, including damage to toilets and washing machines. This poses a wide range of hazards for your space. For example, if the water is used for drinking purposes, it can cause health risks like gastrointestinal issues and parasitic infection. You should never drink rainwater without appropriate treatment and filtration.

On the other hand, contaminated water can worsen existing skin conditions. This comes down to the presence of chlorine and heavy metals which are very drying. Which is why, to prevent a bacteria breeding ground it’s important to maintain your tank regularly.

When Should I Clean my Rainwater Tank?

On average, it’s important to clean and inspect your tank every 1-2 years. However, it’s important to note that the frequency of cleaning depends on many factors.

Environment: Tanks near trees or in dusty areas collect debris and sediment more quickly. Some areas in Sydney, like Kuringai or housing estates nearby heavy industry or salt water need to have even more regular cleaning
Water Usage: Heavy rainwater use or low circulation can lead to faster contamination.
System Setup: First-flush diverters and filters reduce the need for frequent cleaning.
Tank Condition: Older or poorly maintained tanks may require more regular attention.
Wildlife Exposure: Animal or insect intrusion increases the risk of contamination. If an animal dies in the gutter system, the decomposing body will contaminate tank water.

How To: Keep Tank Water Clear

Now that the rainwater tank is completely clear, you may be wondering “How can I prevent rainwater tank contamination?”

Luckily, there are many preventative measures you can take for your tank. These are all crucial in keeping your rainwater tank clean for ongoing use.

Explore some steps you can take below:

Installation of a first flush diverter: As implied by the name, this diverts the first flush of water away from your tank. This is important because this water contains the most contaminants.
Leaf strains and mesh filters: Through these filtration systems, you’ll prevent the entry of leaves and other larger debris which causes clogs. The mesh filters also work to capture the much finer debris.
UV water filtration: To sterilise and target any microorganisms, the UV filters are very effective for these. This chemical free process is designed to ensure that the rainwater is safe for use.

When Should I Choose a Water Tank Cleaning Service?

While DIY tank cleaning is effective, for a more major tank clean it’s important to see a professional. An expert tank cleaner will have the right expertise, specialised equipment and knowledge. This is especially important in cleaning tanks within hard to reach areas, such as underground water tanks.
