Best quality, best price, best advice

Proudly made in New Zealand, our tanks are made to last. With a 10 year warranty and we can even install. We cater for farms and lifestyle properties where large water supply collection is needed, to smaller tanks for extra water usage like watering the garden or washing the car through to emergency water supply tanks where a small tank holds a supply of water in case of a natural disaster where water is in short supply.
