Commercial & Residential Backup Water Tanks

When the municipal supply stops, your business, estate, school or home shouldn't. Engineered steel backup storage keeps taps open through every outage — and harvests rainwater the rest of the year.

Municipal water interruptions are no longer exceptions in South Africa — bursts, throttling, water-shifting and infrastructure failures are part of operating reality. For a shop, restaurant, school, medical practice or estate, a no-water day is a closed-for-business day. Backup storage turns that risk into a non-event.

The Challenge

Most businesses discover their water dependency the day the taps run dry: ablutions close, kitchens stop, tenants complain, patients are turned away. Small plastic tanks help a household for hours — but commercial demand needs engineered volume, and cheap tanks in the sun age fast precisely where reliability matters.

The Aquasteel Solution

The Home Tank™ (Chromadek®) covers residential and small-commercial duty, while the Dura Tank™ scales to estates, schools, hospitals and office parks — with an optional AquaGuard potable liner (AS/NZS 4020) for drinking water.

Disruption avoided — 12 no-water days/yr at R2,500/day (full 2-day coverage at 5 kL/day)R30,000/yr
Rainwater harvested — 176 kL/yr off a 400 m² roof, at R45/kLR7,920/yr
Less: maintenance provision (1% of investment)−R1,500/yr
Net annual benefitR36,420/yr

Every outage the tank bridges is a trading day saved — and every rainy season cuts the bill. Most backup installations repay themselves well inside five years.

Backup Storage FAQ

Common Questions

How much backup water does a business need?

Size for at least two days of normal demand — enough to bridge a typical municipal outage. A business using 5 kL/day needs a minimum 10 kL reserve; estates, schools and hospitals scale up from there. Use the sizing tool to match your demand.

Is a backup water tank worth it?

Counting avoided closure days and rainwater harvesting, payback of 3–5 years against a 30+ year tank life is common. Run your own numbers in the ROI calculator.
