Water Tank Solutions


Whether you live rurally, rely on rainwater, or simply want a backup water supply, a high-quality tank system is essential. At Aqua, we install, repair, and maintain water tanks for residential homes, rural properties, and commercial/industrial sites.

From rainwater harvesting to large-scale farm storage, we provide full end-to-end plumbing solutions and supply trusted tank brands built for Kiwi weather.
