Rainwater Tank Cleaning Service

Rainwater tanks should be inspected and cleaned at least every 2-3 years to ensure that the water is in good condition for use within a house or business. Over time leaves, dirt, pollen, gum nuts and other material may enter the rainwater tank as it rains and build up on the tank floor. Here they break down, dissolve, go rotten and contaminate the water making it foul tasting and putrid. This will greatly affect the quality of the water.

"We clean water tanks when full or near empty with a process that uses minimal water"

We offer professional water tank cleaning service to remove the sludge from your rainwater tank walls and floor. Our process is accurate and efficient and removes minimal water. The tank water is not stirred up and can be used the same day after cleaning. We can clean your rainwater tank either full or near empty and don’t need to remove all the water.

Tips to help keep Your Rainwater Tank in Good Condition

The problem starts at the collection point. Leaves piled on the roof and in the house guttering create tannin staining of the water and quickly find their way down into the rainwater tank.

Leaves trapped in tank inlet screens must be cleared on a regular basis. If left to build up they will pollute and tannin stain the rainwater as they decompose acting like a giant tea strainer.

Bird waste  can introduce harmful bacteria such as E-Coli, Giardia, Salmonella, Campylobacter and Cryptosporidium to the rainwater supply. Watch for birds nesting under solar panels!

Animal waste on the roof and in the guttering can introduce unsafe levels of bacteria to the rainwater supply so check under overhanging tree branches. Filtration with U.V. sterilisation is  recommended.

It is very important that all water inlets to rainwater tanks and overflow outlets be screened to prevent rodents, birds, bats, snakes and possums from entering the tank in search of a regular water supply. Once in the tank they cannot escape where they will sadly die and quickly pollute the water!

Many people claim ‘My rainwater is fine, never hurt me’, ‘Been drinking it all my life, it’s natural’, ‘I don’t need my tank cleaned or filters installed’. That is fine, they have a right to their own opinion but here are the facts. Studies have been done on rainwater tanks that revealed a high percentage of tanks are not safe to drink from and contain dangerous E.coli bacteria levels. With a dead possum inside your rainwater tank how safe do you think the water would be to drink? You decide.

Sludge breeds bacteria in down pipes especially over the summer months so ensure they are drained as often as possible. Underground concrete rainwater tanks need to be inspected at least every 12-months for tree roots penetration as water pollution and damage to the tank can occur.

Another serious rainwater contamination problem is the supply of rainwater from the house gutters to the tank via a ‘Wet System’. This is where the rainwater travels from the guttering down into a sealed system of underground pipes and then up and over into the rainwater tank.

This ‘Wet System’ works well when it is raining however when the rain stops the water in the wet system becomes stagnant and this pollutes the water with bad colour, taste and odour. The next time it rains this putrid water is flushed directly into the rainwater tank. It is extremely important that this water is drained from the wet system at the lowest point as often as possible when it is not raining. This will ensure a clean pipeline awaits the next rain.

We recommend the installation of a 90mm PVC Gate Flush Valve to the wet system at the lowest point possible. If access to this point is unavailable, install the flush valve at ground level and open the valve several times when it is raining heavily to flush out the lower sludge level in the bottom of the system.

This water pipe cross-section shows the sludge buildup inside a non-flushed wet-system.

Installation of a 90mm PVC Gate Flush Valve allows quick flushing of the wet-system line.
