320,000 Litre Aqualine Steel Water Tank

With 320,000 litres of water storage the ASL320 steel tank is ideal for situations that require a large volume of water to be stored. These include rural farms, mining sites, resource projects, storm water management systems and large commercial industrial buildings.  

These large 320,000L steel rainwater tanks include hot dipped galvanised roof trusses ensuring good corrosion protection. Plus, the corrugated walls and roof blend in with most industrial and commercial buildings. There are no sacrificial anodes to be installed and maintained. Aqualine steel tanks do not require anodes, that typically need to be replaced every 5 years. A durable polyethylene liner is used which ensures that the tank remains leak free and meets the AS/NZS4020 potable water standard. This means the 280,000L steel rainwater tank is safe for drinking water. Bushmans does however recommend that a filter is utilised before drinking water from a rainwater tank.
