Deep-seated groundwater plus an engineered bolted-steel reservoir — for estates, communities and farms done waiting on a municipal pipe that may or may not deliver.
If your only water is the municipal pipe, your estate, farm or business runs on someone else's maintenance schedule. Throttling, outages and tanker weeks aren't emergencies anymore — they're the pattern.
Supply is throttled or cut without notice — and your operation stops with it.
Water tankers cost a fortune and arrive on their schedule, not yours.
A plastic tank on a stand buys you hours of buffer, not independence.
Every outage, the same scramble — and the next one is already coming.
Deep-seated groundwater under your own ground, pumped on your own schedule.
Days of engineered bulk storage — sized to your real demand, not to a catalogue.
PosMac® alloy-coated steel — with an optional AquaGuard potable liner, certified to AS/NZS 4020, when it’s drinking water.
The pipe becomes your backup. Your reservoir becomes the plan.
Water security isn't a bigger buffer. It's owning the source and the storage.
From a farm reserve to 11.8 million litres in one bolted flat-panel reservoir — Ø 3 to 37 m. Real days of supply, not hours.
Add the optional AquaGuard 720 g reinforced PVC liner — heat-welded seams, AS/NZS 4020 certified — when the duty is drinking water. Skip it when it isn’t.
PosMac® zinc-aluminium-magnesium alloy coating with self-healing cut-edge protection — outlasting conventional galvanised in Africa’s toughest conditions.
Bolted and modular — expand, relocate or re-use the same shell as the estate, scheme or farm grows. Storage that keeps up.
The same flat-panel Dura Tank system we build for municipal reservoirs and mines — designed to AWWA D103-97, sized ring by ring from our own engineering calculator, and signed off per site.

Indicative ranges for planning. Every Dura Tank is sized, load-checked and signed off by a professional engineer for your demand, site and wind zone before fabrication. Borehole yield testing and pump design by your drilling contractor or ours. Size your tank in the tool →
Not imported in a container. Designed, punched and rolled in our own factory — so panels fit, liners are tailored here, and the engineering answers to us.
Your Dura Tank is raised by trained, certified installer teams close to your site — not a crew flown in from far away and billed to you.
The reason is the same everywhere: nobody can afford to run on a supply they don't control. What changes is the scale. A Dura Tank is the water bank behind each of these.
Eco estates, lifestyle developments and body corporates — one borehole, one reservoir, and the outage notice stops mattering.
Stock water across camps, irrigation reserve, rainwater off every roof — banked in bulk. Rest the borehole; pump off-peak or on solar; feed the farm by gravity.
Lodges, schools, clinics, factories and packhouses — operations that stop when the pipe does, unless the reservoir says otherwise.
Different gates, same principle: own the source, own the storage — and the pipe becomes your backup.
Fifty households with fifty plastic tanks are fifty people waiting for a tanker. Fifty households on one borehole and one engineered reservoir are a water scheme.
A hydrogeologist sites the borehole; drilling and yield testing prove what's really under your ground. Deep-seated water is an asset — treat it like one.
One Dura Tank sized to the scheme's real daily demand plus reserve — potable-lined, engineered, and expandable as members join.
The body corporate, trust or scheme committee owns the system. Metered draw-offs, shared running costs — and nobody waits on the municipal pipe again.
We'll help you size the reservoir to your combined demand, plan the layout, and phase the build so the scheme grows one ring — and one member — at a time. Talk to us about a scheme →
Your ground already holds the water. We build the half above it.
A reservoir is more than a purchase. It's the point where your estate, community or farm stops hoping the pipe delivers and starts controlling its own supply — source, storage and all. That's not just convenience. It's independence you can measure in litres. We build the steel. You take back the tap.
