Structural Water Tank Upgrades for Industrial and Public Use
Premier Tank Inc provides on-site structural upgrades for large welded water tanks used in municipal, industrial, and agricultural systems throughout California. With more than 30 years of experience in the tank construction and repair industry, we help clients improve the safety, compliance, and functionality of aging water tank infrastructure.
Our upgrades are designed to reinforce structural integrity, meet seismic and safety codes, and extend the service life of high-volume welded tanks. We work directly with water districts, contractors, and public agencies to assess tank conditions and implement code-compliant, long-lasting improvements.
Whether prompted by inspection reports, operational changes, or aging materials, our upgrade services are tailored to the specific needs of each tank and site.

Why Water Tank Upgrades Are Critical
Welded water tanks face long-term stress from environmental exposure, internal pressure, and fluctuating water loads. Over time, even well-built tanks can suffer from corrosion, metal fatigue, structural shifting, or outdated safety configurations.
Delaying upgrades increases risk of leaks, failure, and regulatory non-compliance. Upgrading a tank before major damage occurs protects your investment and ensures uninterrupted service to the communities or operations that depend on it.
Common reasons for upgrading large welded tanks include:
- Structural code changes or seismic retrofitting requirements
- Deterioration of roof or floor plates
- Corrosion beneath old coatings or linings
- Need for safer access or improved inspection pathways
- Expansion of system demands or capacity
Premier Tank Inc evaluates these concerns and delivers reliable upgrade solutions that keep tank systems safe and in service for the long term.
our water tank
upgrade services
We perform full-scope upgrades for large welded steel tanks used in water storage. Every project begins with a structural evaluation and project scope review to identify areas of improvement.
Upgrade capabilities include:
Seismic and Structural Reinforcement
California's seismic zones require welded tanks to meet updated movement and load-bearing standards. We retrofit tanks with bracing, structural tie-ins, and flexible components that meet current seismic codes and improve overall tank stability.
Roof and Floor Plate Replacement
Corrosion and wear at the roof and floor are common in older tanks. We remove and replace worn steel sections with new plate material and certified welds. This protects the tank’s integrity and prevents water intrusion or contamination.
Access Hatch, Ladder, and Railing Improvements
Older tanks often lack safe or accessible entry points. We install or upgrade:
- OSHA-compliant access ladders
- Safety railings and fall protection
- Locking hatches and sealed manways
- Platforms and landing points for inspections
Upgrades improve safety for inspection crews and reduce liability for facility owners.
Coating Preparation and Surface Work
Before any coating is applied, surface prep is essential. We provide:
- Blasting and grinding
- Rust and scale removal
- Coating removal from steel surfaces
- Weld prep and edge conditioning
Proper preparation ensures coatings bond correctly and protect against long-term corrosion.
Component Modernization and Retrofits
We can replace or add:
- Nozzles and inlet/outlet valves
- Overflow piping
- Level indicators and instrumentation ports
- Expansion joints or flexible connections
- Ventilation systems
All retrofits are completed to match current performance needs and meet regulatory expectations.
