Municipal Water Storage Tanks

Reliable, compliant bulk water infrastructure for municipalities. Aquasteel designs, manufactures and installs engineered steel tanks for bulk storage, distribution reservoirs and community supply across urban and rural environments.

With increasing pressure on municipal systems from population growth, aging infrastructure and climate variability, robust water storage is no longer optional — it is critical. Municipal storage must perform under continuous cycling, fluctuating water levels and exposure to UV, temperature extremes and corrosive atmospheres, while maintaining structural integrity and water quality over extended operational lifespans.

The Challenge

Municipalities must balance regulatory compliance, operational efficiency and cost control. Corrosion, structural fatigue and coating degradation are common failure points in poorly designed systems — leading to service interruptions, water losses and costly emergency repairs. Demand must grow without compromising reliability, which calls for scalable solutions that can expand without disrupting existing infrastructure.

The Aquasteel Solution

Aquasteel provides sectional bolted steel tanks for high-capacity potable water storage, suitable for both ground-level and elevated installations. Modular design enables rapid on-site assembly, reducing project timelines and labour costs. A key differentiator is the use of Fusion Bonded Epoxy (FBE) coated panels for exceptional corrosion resistance — a durable, hygienic solution that meets international standards in harsh African conditions.

Return on Investment

What a Municipal Reservoir Earns Back

Worked example — a 1,000 kL steel reservoir, ±R2.0 m installed

Conservative sample assumptions. Adjust every figure to your own operation in the calculator.

Tanker deliveries replaced — 2,000 kL/yr (R120 vs R14/kL)R212,000/yr
Emergency response cost avoided (50% of R150,000)R75,000/yr
Billable water protected — 5,000 kL/yr at R14/kLR70,000/yr
Less: maintenance provision (1% of investment)−R20,000/yr
Net annual benefitR337,000/yr

Tankered water at R100–150/kL is the most expensive water a municipality ever buys. Stored bulk water eliminates it — and keeps revenue water flowing through outages.
