Rainwater tanks

Brisbane summer wouldn’t be the same without the mozzies. If it’s not enough that they’re breeding madly in flood waters, they’re coming for your rainwater tank! Rainwater tanks are a great way to save on your water bills, if you can keep the local mosquitoes out! So, how do you keep mosquitoes out of your rainwater tank?

Stored water makes a perfect home for mosquitoes

The collection of rainwater is a system that can be of great benefit to the environment and your water bills. But any plumbing system that collects and stores water needs to be maintained, and the rainwater tank is one such system that is often out of sight, so out of mind. Mosquitoes use rainwater tanks to lay eggs and raise larvae – you could be pumping baby mozzies into your pool or directly into your garden irrigation system.

Mosquitoes are the most dangerous creatures on earth!

This mosquito is the culprit for infectious diseases including dengue, Zika, chikungunya and yellow fever. Here in Queensland, we’re susceptible to Ross River Fever outbreaks. Ross River Fever isn’t usually deadly but it can shatter you immune system and make you very, very sick, for months, if not years. Dengue and Ross River Fever are real risks to Brisbane families.

The most common areas for mosquitoes to breed are near water supplies and CSIRO are urging all rainwater tank owners within Brisbane to check their rainwater tank systems to prevent an outbreak of dengue fever.

Research has shown the last epidemic for dengue fever in Brisbane was when the use of unsealed water tanks was prevalent. It’s important to check the current state of your rainwater tank installation and fix these issues if found during your inspection. If necessary, Salmon Plumbers Brisbane can do hassle-free rainwater tank replacements.

How to keep mosquitoes out of your rainwater tank

1. Check the mesh sieves into and from your rainwater tank

The mesh barrier at the top of your rainwater tank should be intact and have no penetrations. Any holes will attract mosquitoes. Replace the mesh to keep mozzies out of your tank.

2. Clean all gutters and downpipes

Leaf matter attracts mosquitoes as this is their food source. Remove the food and the mozzies won’t come looking for a home. Ensure your gutters and downpipes are free from all leaf debris. It’s important to clean your gutters twice a year, not just to prevent mosquito infestations but for flood prevention too.

3. Inspect the tank and check for holes or penetrations

Any penetrations or open holes into the rainwater tank are basically inviting the mosquitoes in. Replace or fix broken rainwater tanks. Your plumber can give you a quote on the cost to replace and install a split rainwater tank.

4. Check your first flush device

Your first flush device, connected to the outlet of the water tank should be flushed every 3 months. A biannual inspection can check for malfunctions and the possibility of mosquito presence.

5. Treat the water

To prevent mosquitoes from breeding in your rainwater tank, the water can be treated. This will stop mosquitoes laying eggs and kill any larvae already present in the tank.
