Raw Water Tanks for Utilities and Industrial Facilities

Raw water storage requires durable containment for untreated source water before it enters treatment processes or industrial cycles. Tarsco bolted steel tanks are engineered for utilities and industrial facilities that demand reliable, large-capacity performance from their raw water storage tanks.

Engineering Requirements for Raw Water Storage

When water is drawn from a river or reservoir, it contains whatever is present in that source, including sediment, minerals, and runoff. This untreated water is considered raw water. It is commonly stored in tanks before entering treatment processes or industrial systems. Those tanks must provide reliable containment day after day, year after year, regardless of changing source conditions.

Municipal systems use raw water storage tanks to maintain supply ahead of demand. Industrial facilities rely on them for process water and cooling tower operations. Power plants depend on them for a continuous supply, while irrigation systems use them to manage water delivery during pumping cycles. The common thread is volume. These operations need millions of gallons of reliable raw water storage capacity.

From an engineering standpoint, the key performance requirements for raw water tanks are clear. The structure has to withstand significant loads over time, which is why steel is commonly specified for large-capacity storage applications. Coating systems also matter, especially with untreated water that can introduce corrosion risks depending on source conditions. Factory-applied coatings are used to improve consistency and extend service intervals. Just as important, the tank must tie cleanly into the pumping and treatment systems, enabling controlled transfer and stable operation across the entire water supply chain.

Why Our Raw Water Tanks Deliver Reliable Storage

Raw water tanks are expected to carry more than the volume. They have to hold up structurally, handle shifting demand, and stay dependable within a working water system over time.

Large-capacity storage capability

Some facilities need a couple of hundred thousand gallons. Others need millions. Our raw water tanks are available in a wide range of capacities to support both municipal and industrial storage requirements.

Corrosion-resistant coatings

Raw water carries sediment, minerals, and other contaminants that can’t be ignored. We use factory-applied coatings to create a consistent barrier on steel surfaces, helping manage long-term exposure and slowing down material breakdown.

Structural durability for long-term use

Each tank is built from steel components formed and cut with precision equipment, then assembled to meet required standards. The result is a structure designed to remain in service under continuous load without premature wear.

Efficient integration with pumping systems

Storage does not function in isolation. Our raw water storage tanks are designed to connect cleanly with pumps and treatment systems, allowing water to move through the process without unnecessary restriction or instability.

Low maintenance requirements

Coating quality and fabrication control play a direct role in upkeep. When both are controlled during manufacturing, ongoing maintenance becomes more predictable and typically less frequent.

Custom engineering for site conditions

No two sites present the same constraints. Tank dimensions, layout, and supporting elements are adjusted to accommodate location-specific factors, ensuring the system fits into the broader infrastructure without rework.
