Most people we speak to claim they have never had their rainwater tank cleaned, and claim the water comes out fine; just slightly tinted in colour or with a slight eucalyptus taste. What happens over time is that leaves and debris enter the tank and begin to de-compose like compost on the bottom of the tank, turning the water a dark coffee colour. This, in turn, greatly affects the drinking quality and health factor of the water. If there are and water-first flush diverters fitted to the inlet of the rainwater tank, many things commonly enter the tank such as:
Modular Tanks
Galvanised Tanks
Polyethelene Tanks
Fibreglass Tanks	Large Concrete Tanks	Underground Tanks

WARNING!

Entering a rainwater tank is illegal unless the individual and/or company is licensed to enter a confined space to the standard AS/NZS 2865:2001 and has been issued with the appropriate entry permit.
