Survey services
Book a tank survey.
Two depths of survey for water storage tanks, priced on the page rather than behind a quote. One tank or forty — book it, pay for it, and we confirm the date. Only the travel is worked out separately, and that comes from the site ZIP.
Request received.
Your tank schedule is with our engineers. We price the trip against the actual route and come back with a quote — usually the same working day.
Price a survey
Two answers and an address.
Surveys are priced per tank. Travel is worked out from the site ZIP rather than picked off a list, and charged once per visit — six tanks on one site is one trip, not six.
01How deep?
02How many tanks?
No minimum — a single tank is a real job and we will book it. Tanks on the same site share one mobilization charge though, so putting them on one visit is where the saving is: six tanks on one site is one trip, not six.
03Where is the site?
Mobilization is charged once per visit, by driving distance from our Pleasant Grove yard — six tanks on one site is one trip, not six. Type the address with its ZIP and the travel is worked out from it.
Add the site ZIP and the travel is added to the total.
Tank schedule
Tell us what we are walking up to.
This is the part that decides whether the survey is worth what you paid for it. Hand hole covers determine whether the interior can be assessed at all, an existing rectifier changes what gets tested, and the tank's geometry is what anode sizing is calculated from. Filling it in now means the crew arrives with the right equipment on the first visit.
What's included
The difference is whether we put instruments on it.
A visual inspection tells you what the tank looks like. A full CP survey tells you whether the protection on it is actually working.
Visual inspection
Priced at checkout per water storage tank
- Exterior and accessible interior condition assessed
- Coating breakdown, corrosion and deformation recorded
- Findings written against the governing standard
- Prioritized list of what needs attention
Not included
- No testing of the existing cathodic protection system
- No structure-to-electrolyte potential readings
- No photographic record
Full CP system survey
Priced at checkout per water storage tank
- Everything in the visual inspection
- Photographic record throughout the survey
- Structure-to-electrolyte potential readings taken
- Existing anodes, rectifier and wiring tested under load
- Reference cells verified against a portable half-cell
- Readings compared against the −850 mV criterion
- Safety, access and sanitary-protection condition documented
- Engineering report with recommendations and costs
Pipelines, plant test points and buried infrastructure are surveyed too, but they are priced per test station against the route rather than per asset, so they are arranged by enquiry rather than through the cart. Send us the run and we will price it.
Also included, at no extra charge
We document the things that let contamination in.
A cathodic protection survey that only looks at cathodic protection misses the failures that actually take a reservoir out of service. The ladder, the hatch and the vent screen are on the way to the anodes, so while we are up there we document what we can see of the safety and sanitary condition too — and put it in the same report.
Safe access
- Fixed ladders — corrosion, loose, bent or missing rungs and rails, damaged welds and fasteners, clearances, transitions and top extensions
- Safety-climb systems — cable or rigid rail, carriers, guides, sleeves, brackets, anchors, terminal stops, slack, missing parts and any inspection tag on record
- Ladders over 24 ft — the cage, fall-arrest or ladder-safety arrangement documented, and flagged for qualified review where it looks uncertain
- Roofs, platforms and catwalks — guardrails, midrails, toe boards, self-closing gates, ladderway and hatch openings, walking surfaces and unprotected edges
- Confined-space indicators visible without entry — signage, openings and apparent retrieval or anchorage provisions
Sanitary protection
- Hatches and manways — covers, hinges, hold-opens, locks, gaskets, curbs, overhangs, gaps, and evidence of runoff, insect, bird or animal intrusion
- Vents — weather hood or downturn, screen condition, corrosion or holes, missing mesh, roof seals, blockage and nesting
- Overflows and drains — screen, flap or duckbill condition, visible discharge, air gap and cross-connection concerns, and apparent direct connections to storm drains or sewers
- Roof and shell penetrations — open seams, missing plugs or caps, failed sealant, abandoned conduit, corrosion-through, daylight and staining
- Security and access control — locks, gates, fencing, signage, tampering and apparent unauthorized-access routes
What this is, and what it is not
Anything presenting a foreseeable immediate safety or sanitary hazard is communicated on the day, not held back for the report. But this is visual documentation from normally accessible locations and the top hatch — it is not a structural certification, a fall-protection certification, a load test or a confined-space program audit. Where a condition needs one of those, the report says so and says who should do it. Final compliance determinations stay with the owner, the engineer of record and the authority having jurisdiction.
Written against
Only the standards relevant to the tank type, cathodic protection system, location, owner criteria and adopted code edition are applied. Dry-film thickness to ASTM D7091 and pitting evaluation to ASTM G46 are available when separately authorized; they are not in the base survey.
What you get back
A document you can put a budget on.
Not a verbal on site and an invoice afterwards. The survey ends with something you can hand to a board, an engineer, or a capital planning committee.
- 01On siteOur technician works the tank, records readings and photographs everything that matters.
- 02InterpretedAn engineer reviews the data against ACI, ASTM, API, ISO and AMPP criteria — not just tabulated and sent.
- 03ReportedCondition, remaining useful life, prioritized deficiencies and the cost of each corrective option.
Service request
Tell us what you are protecting.
We visit the site before we estimate. Send the structure, the environment and what you already know — an engineer will come back to you, not a call center.
