Water Reservoir Tanks in Arizona

Applications we support

• Potable water and campus distribution

• Irrigation and agricultural reserves

• Process and cooling water for manufacturing

• Fire protection and hydrant supply

• Rainwater harvesting and storm-equalization basins

• Emergency/backup storage and resilience planning

Tank types & when to use them

Bolted steel (epoxy-coated):
Fast to erect, scalable to very large volumes, serviceable panels. Great for municipal, industrial, and fire-water storage.

Welded steel (field or shop):
High structural integrity and custom geometry. Ideal when head pressure, tall shells, or special nozzles are required.

Fiberglass (FRP):
Corrosion-resistant and lighter than steel; strong option for aggressive water chemistries or coastal environments.

Polyethylene (HDPE):
Cost-effective, quick to deploy for small–medium volumes. Best for non-pressurized applications and accessory/secondary storage.

Concrete (cast-in-place or prestressed):
Very long service life and excellent thermal stability; common for large municipal reservoirs or where burial is preferred.

Bladder/collapsible tanks:
Rapid, temporary, or remote deployments; emergency and seasonal use.

We’ll recommend the right material, liner, and coating system for Arizona’s UV, heat, dust, and hard-water conditions.

Sizing & design considerations

• Capacity & duty: Daily demand, peak/diurnal use, fire-flow reserve, and contingency needs

• Water quality: Hardness, silica, TDS, and disinfectant strategy (chlorination/chloramination)

• Foundation & site: Bearing capacity, wind/seismic loads, drainage, access, and secondary containment as required

• Coatings & liners: NSF-61 contact surfaces, corrosion allowance, cathodic protection (sacrificial or impressed current)

• Instrumentation: Level transmitters, overflow/vents, mix systems, sample taps, and SCADA tie-ins

Our installation process

1. Site walk & proposal: Verify capacity, siting, tie-ins, and permitting path

2. Engineering & submittals: Drawings, foundation design, coatings/liner specs

3. Civil & foundations: Grading, ringwall or mat foundation, conduits and drains

4. Tank erection & piping: Shell, roof, nozzles, ladders, vents, overflow, and yard piping

5. Disinfection & testing: Hydrostatic test, leak check, disinfection, and water-quality verification

6. Turnover & training: O&M manuals, spare parts, and operator walk-through

Maintenance that extends service life

• Interior cleaning & inspection: Remove sediment/biofilm; inspect seams, coatings, and appurtenances

• Coating touch-ups & relines: Repair holidays, recoats, or liner replacement when adhesion or thickness falls below spec

• CP monitoring: Anode replacement or rectifier tuning to control corrosion

• Valve & level control service: Floats, altitude valves, actuators, and telemetry checks

• Annual report: Photos, thickness/holiday test data, and prioritized recommendations

Cost & schedule drivers (so you can plan)

• Capacity and height; material (steel/FRP/poly/concrete)

• Coating/liner system and NSF-61 requirements

• Foundation type and site access/crane logistics

• Appurtenances (mixers, heaters, insulation, instrumentation)

• Inspection, disinfection, and startup scope

FAQs

How do I size a reservoir tank for my facility?
Start with average daily demand, add peak/hourly draw, and include reserve for fire-flow or emergency duration. We’ll model cycles and recommend capacity with a safety margin tailored to your use case.

Can these tanks store drinking water?
Yes. We specify NSF/ANSI 61-compliant coatings/liners and disinfection procedures, then provide water-quality documentation at startup.

What’s the typical maintenance interval?
Plan on an external inspection quarterly, internal inspection/cleaning every 12–24 months (more often for high-TDS or sediment-laden sources), and coating/CP evaluations annually.

Above-ground or buried—what’s better in Arizona?
Above-ground tanks are faster to deploy and easier to inspect. Buried or partially buried reservoirs can reduce thermal swings and visual impact but add civil complexity. We’ll help weigh lifecycle cost, temperature control, and permitting.

How long do water reservoir tanks last?
With proper coatings and maintenance, bolted/welded steel tanks often exceed 25–40 years; concrete can last longer. Poly and FRP are typically 15–30+ years depending on exposure and care.

Do you assist with permits and fire-code requirements?
Yes. We coordinate submittals, foundation calculations, and, for fire-water, NFPA 22 appurtenances (vents, overflows, anti-vortex, signage) to streamline approvals.

What water-quality issues are common in Arizona?
Hardness, high TDS, and silica drive scale formation. We design for accessible cleaning, specify compatible liners, and can integrate mixing and treatment strategies to manage deposition.
