Water Storage Tank Solutions

Bolted steel water storage tanks are factory-coated steel panel tanks assembled on site, used where a utility or plant needs large-volume storage without field welding. Tarsco builds them from potable service through wastewater treatment, in capacities to 4 million gallons, to AWWA D103, AWWA D100, NFPA 22 and API 12B principles, with NSF/ANSI 61 certified Enduro Coat Fusion Bonded Epoxy where the water is treated or potable.

Engineered for Compliance: Water Storage Tank Solutions

Getting water storage right isn't just about capacity; it's about engineering for specific challenges. At Tarsco, we design durable tanks that stand up to the rigors of potable systems, municipal treatment plants, and industrial processing. Our water tanks perform reliably at every stage, from initial equalization and sludge holding to final clarification in both aerobic and anaerobic digesters.

We factor in everything from chemical exposure and pH levels to structural demands and the need for secondary containment. By following AWWA D103 and NFPA-22 standards from the ground up, we position projects for a smooth approval process. The result is a storage solution that lowers risk and delivers reliable ongoing performance.

Built for Performance: The Advantages of Tarsco Water Tanks

What makes a Tarsco water tank the smart choice for engineers and operators? It’s the combination of robust construction, practical design, and a focus on your total cost of ownership.

Tank Specifications

  • We build tanks for the entire treatment cycle, including mixing, flocculation, sedimentation, and digesting.
  • A wide range of capacities, all featuring durable epoxy or glass-fused coatings that fight corrosion for years.
  • The modular bolted design isn’t just for easy assembly. It lets you adapt capacity later and ensures compliance with AWWA, NSF, and NFPA.
  • Need secondary containment or other safety features? We integrate them to meet your site's specific regulatory demands.

Operational Benefits

  • Because our tanks arrive as manageable components, your crew can install them faster, with minimal welding and reduced labor time, accelerating your project timeline.
  • The efficient shipping packages we use dramatically lower your freight costs and make site handling straightforward, even in tight or remote locations.
  • Replace a damaged component without heavy equipment or specialized tools, slashing maintenance complexity and cost.
  • Altogether, you get a lower installed cost, a faster commissioning date, and a tank known for its operational reliability year after year.

FAQs About Water Tanks

Compare our tank types to find the best solution for your specific application requirements

For atmospheric storage designed to AWWA/API, bolted tanks meet the same loads (hydrostatic, wind, seismic). Welded tanks are preferred for pressure service or extreme temperatures. Strength depends on code, thickness, and detailing - not the joint type alone.
Bolted panel tanks are factory-coated and field-assembled, so erection runs under half the time of a field-welded or concrete tank and the coating is applied under controlled factory conditions rather than on site. Welded tanks to AWWA D100 remain the choice where a fully continuous shell is specified.
Yes – the bolted panel design allows additional shell courses or panel replacement without heavy equipment.
Properly designed and erected, no. Gasketed seams, controlled bolt torque, quality coatings/liners, and hydrostatic testing deliver tightness. Periodic inspections and gasket replacement maintain long-term performance.
For liquid containment, yes - a sealed bottom (steel or concrete with membrane liner) is essential. Exceptions are special foundations with certified liners. Bottom choice depends on fluid, hygiene, and code/secondary containment needs.
Individual capacities are engineered to 4 million gallons.
pH 3 to 14, with a 200 F limit immersed and 300 F dry.
Bolted: modular panels, factory coatings/liners, fast erection, easy expansion/repair; ideal for atmospheric service. Welded: monolithic shell, best for custom shapes/pressure or certain chemicals; more site work and coating in the field.
Enduro Coat Fusion Bonded Epoxy, factory-applied and thermally cured, certified to NSF/ANSI 61 for potable contact.
AWWA D103, AWWA D100, NFPA 22 and API 12B principles, with FM where the project requires it.
By protective systems: factory powder/glass-fused/epoxy linings, galvanizing, sealants, cathodic protection (anodes), edge protection, and rigorous surface prep. Regular inspection and timely touch-ups keep steel protected for decades.
