Potable water tank condition assessment focuses on understanding the current state of drinking water storage systems and identifying factors that may affect safety, performance, and water quality. This process establishes a reliable baseline condition through visual review and targeted procedures applied only where required.
A comprehensive condition-based approach considers all elements influencing long-term tank reliability, including structural integrity, surface condition, environmental exposure, and operational history. Rather than delivering standalone services, each assessment activity contributes to a clear and objective overview of tank condition.
At Raven Tanks, condition-focused procedures are applied selectively to confirm findings and support informed decision-making.
Accurate diagnosis of tank condition depends on clear access to internal surfaces. Where necessary, controlled cleaning is used as a diagnostic step to expose coatings, joints, and structural elements that cannot be reliably assessed otherwise.
This process allows for the identification of coating breakdown, corrosion indicators, contamination sources, and wear patterns that may affect potable water quality. Each diagnostic step contributes to a reliable condition profile rather than ongoing tank care activities.
Condition findings may indicate that existing protective systems are no longer performing as intended. In such cases, the assessment may recommend the use of ANSI/NSF-approved coating systems to restore protection and extend asset life.
Any coating recommendations are based solely on assessment outcomes and are provided as follow-up options. Coating application itself is delivered as a separate service to ensure clear separation between condition assessment and remedial works.
Raven Tanks performs washouts and recoating services in strict compliance with all applicable OSHA safety regulations. This includes lead abatement and containment requirements.
NACE-certified specialists oversee blasting, priming, and finish coats at every stage. Their work ensures municipal water tank cleaning and recoating projects meet specs and deliver consistent, high-quality results.
Raven Tanks, an ISO 9001:2015 Quality Certified company, drives functional excellence and continuous improvement. We focus on safety, compliance, and efficiency to exceed customer expectations. At the same time, we extend the service life and reliability of every water tank we maintain.
Where physical access presents safety or operational limitations, drone and ROV technologies may be used to support the condition assessment process. These tools allow visual evaluation of internal surfaces without unnecessary entry or system disruption.
Drone and ROV observations supplement assessment findings and assist in confirming condition-related concerns. Their use remains focused on supporting accurate evaluation rather than replacing dedicated inspection services delivered through specialist non-entry inspection methods.
We know our clients often have important questions before starting a project. Here are clear answers to help you make informed decisions with confidence.
A potable water tank condition assessment provides a structured evaluation of the tank’s current state, including surface condition, structural integrity, and factors that may affect water quality. The service focuses on identifying risks and establishing a clear condition baseline rather than performing maintenance or repair works.
No. Cleaning is only carried out where surface buildup or sediment prevents accurate evaluation of internal surfaces. When used, cleaning serves a diagnostic purpose only and is applied selectively to support reliable condition findings.
No. Repairs, recoating, and other remedial works are not included within the condition assessment service. Where assessment findings indicate further action may be required, these works are recommended as separate services to maintain a clear service scope.
A condition assessment is typically undertaken when there are concerns about water quality, asset age, visible deterioration, or uncertainty around current tank performance. It is also used to support planning decisions before committing to maintenance, recoating, or upgrade works.
