Sediment collects in tanks from the rain run off from your roof, which includes the dirt, moss, leaves and insects as well as pollutants. The sediment can make your water discoloured and affect its taste and quality as well as be a home for bacteria, affecting the health of your water. Regular cleaning helps to keep your water fresh, healthy and reduces the risk of bacteria.
Over the years we have cleaned out many water tanks and found sludge, mud, tree roots and leaves as well as rotting snakes, birds, possums, snails, rats and mice (click the image above for a fun look at what goes on). Getting your tank regularly cleaned helps to keep these nasties out of your drinking water. Sand and silt drawn through your pump can also cause costly damage, otherwise avoidable with a clean tank.
Businesses and schools, who rely on tank water, may have a legal obligation to maintain their water to certain standards (set by individual councils).
