Fast
Moveable and expandable
Quick to construct, easy to service, and adaptable to changing storage demand.
Capacity, footprint, access and air-space constraints can all be designed around. Timbertanks can be configured as tall narrow barrels, wide low-profile reservoirs, or elevated tanks where the site requires it.

Reservoirs and
large-scale storage
First developed for domestic potable water in the early 1970s, Timbertanks now provide durable, cost-effective storage for councils, utilities, industry, farms, and private properties across New Zealand. Ongoing development in manufacturing and construction has enabled larger reservoirs while preserving the speed, flexibility, and sustainability of on-site timber construction.
Reservoir capacities range from 100 m³ to 6,000 m³, with design-build solutions tailored to site access, footprint, and operating conditions. They are ideal for potable water storage projects that need a system that is expandable, moveable, and easy to service, as demonstrated by the 3,000 m³ reservoir delivered in Whitianga.
Timber barrel
Treated radiata pine staves contained by hot-dipped galvanized steel cables.
Liner system
Four synthetic liner options housed within a polyethylene preliner for a sealed interior.
Structural roof
Engineered timber roofing that stabilizes the structure and protects water from UV exposure.
Domestic water storage
that fits the property
Timbertanks are ideal for rainwater harvesting, holiday homes without municipal supply, and urban sites needing an economical supplementary water source. Their natural timber finish sits comfortably in established landscaping and can be stained to suit the setting.
Package delivery makes them especially practical for difficult access conditions. Tanks can pass through most gateways and be installed in mature gardens, tight urban backyards, or sites without direct road access.

Firefighting reservoirs
for constrained sites
Fire protection systems often require significant water volumes on sites that are already heavily developed. The design flexibility of a Timbertank reservoir, combined with efficient on-site construction, allows that firefighting reservoir to be placed where conventional systems struggle.
Depending on available area and headroom, tanks can be configured as tall narrow barrels, wide low-profile forms, or flat-roofed reservoirs located under mezzanines, inside buildings, or in basement spaces.
