Water Tanks

Important: delivery instructions

City Tanks
City Tank Metro Water, the monopoly water supplier to Auckland city charges around $1000 to $1200 for a family of four, yearly water supply.

They do this by firstly charging a water rate for water usage, and then they charge 75% of that usage for discharging the water. Basically if you use $700 worth of water, you get charged $500 for discharging it as well. By installing one of our City Tank dual water systems you can bypass most of the Metro Water charges, and we believe savings of up to 70% can be made.

This means that your $1200 water bill could drop to as low as $360.

We can manufacture any size tank either underground or on top of the ground to meet either your total or partial water needs.
