Water Storage Tank Exterior Inspection Logger
Ground-level tank walkdown — coating, foundation, vents/screens, security, overflow and site issues for elevated and ground storage; offline log.
New storage tank inspection
Walk the site monthly for security/sanitary items; comprehensive interior/exterior inspections by specialists every 3–5 years per AWWA practice.
Field guide: Water Storage Tank Exterior Inspection Logger
Storage tanks have a special place in waterborne-outbreak history: the Salmonella outbreaks traced to bird droppings entering through torn vent screens and unsealed hatches taught the industry that tank sanitation is mostly about screens, gaskets and locks — items a ground-level monthly walk can fully check. This logger leads with those sanitary protections and treats any breach (torn vent screen, missing overflow flap, unlocked hatch) as the highest finding class, because each is a direct contamination pathway to thousands of customers.
The rest of the walkdown covers what drives tank capital planning: exterior coating condition (the coating IS the tank — steel under failed coating is on a countdown), foundation and anchor condition, the safety-climb system that determines whether anyone can legally go up, and site security. Telecom co-location gets a line because antenna crews loosen what they touch.
Field tips
- Binoculars make a monthly walk a real inspection — vent screens and hatch positions are checkable from the ground.
- After every storm, check the overflow discharge for fresh erosion; an overflow event you didn't know about is a control problem.
- Treat contractor visits as inspection triggers: re-walk the site the day antenna or painting crews leave.

Frequently asked questions
Why are vent screens such a big deal?+
The tank breathes as levels change, and the vent is an open pipe to the water surface. The screen (typically 24-mesh non-corrodible) is all that excludes birds and insects. Documented outbreaks — including fatal ones — trace to exactly this failure, which costs a few dollars of mesh to fix and a tank's worth of trust to ignore.
How often do tanks need professional inspection?+
AWWA practice is a comprehensive inspection every 3–5 years (dive, float-down ROV, or drained), covering interior coating, sediment and structure. The monthly site walks this log captures are the layer between those — sanitary, security and obvious-change detection.
What does exterior coating condition tell me?+
Chalking and fading are cosmetic; rust staining means moisture under the film; visible pitting means the steel is being consumed. Coating projects run cheaper-per-year the earlier they're done — logging progression with dates and photos is what justifies repainting before pit repair welding enters the bid.
Is telecom equipment on tanks a problem?+
It's revenue and risk: leases are valuable, but every penetration, mount and cable path is a corrosion and sanitary consideration, and crews on the tank are an access-control variable. Best practice is logging co-location condition each walk and inspecting after every carrier visit — loose mounts and abandoned cables accumulate otherwise.
