When was your rainwater tank cleaned last?

webpics-3-042-2Rainwater 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 and make it almost unusable.

These contaminants and others such as waste from birds, possums, koalas and rodents can quickly create a large problem with the health of the water supply which, if consumed, can lead to serious illness of a family member.

Insects, frogs, lizards, snakes and rodents are often discovered decomposing on the bottom of tanks during the cleaning process. They find their way into the rainwater tank through water inlet pipes, cracks, holes, incorrectly fastened or left open manhole access covers, tank overflows, disconnected pipes etc. It is also very important to have a water filter screen installed to the water inlet to your water tank to prevent these creatures possibly being washed into the tank when it rains.

We offer our standard tank cleaning service removing the sludge from the tank floor. This process removes minimal water and the tank can be full or almost empty and the tank water can be used the same day after cleaning.

We also offer a complete flush and drain tank cleaning service as required. This process removes all the contaminated water and the tank is completely flushed and drained. No chemicals are used in either tank cleaning process.

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 can heat up in warm weather.

As the wet system pipeline contains contaminants bacteria quickly breeds and 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.

With the rainwater tank cleaned and inspected on a regular basis we also recommend a rainwater filtration system be installed. Read more about Rainwater Filtration »
