Anchor water tanks to ground to prevent floatation.

Rainwater tanks are a great addition to any property and enable self-sufficiency and water security. A significant flood event could uplift a full water tank drive it into your house or garage. Or water tanks could be swept downstream, causing damage to other properties.

A full 2000-liter rainwater tank weighs just over two tones, which could cause significant destruction. And you don't want the added cost of repairing or replacing and reinstalling tanks and pumps.

Securing the water tanks to the ground or wall by a strap or anchor will ensure they remain in place. In the event of a flood, If tanks tip over they could break water and gas pipes, or damage pressure pumps. 

Ensure your tank overflow is adequate and clear of debris. A locked tank overflow will cause water to flow over from the top of the tank, which may result in erosion of the tank base in heavy downpours. If your tank base is crushed rock or road base, sandbag the base to avoid erosion, which leads to instability.

Protect your tank pressure pump by removing and relocating it somewhere dry. If your pump becomes submerged, it is unlikely to operate and your warranty will be void. 

If your tanks are underground, relocate the pressure pump before bad weather. Contaminated water can be disinfected using a non-chorine food-grade tank water purification agent.
