Crawler Vac reservoir sediment removal

Robotic reservoir sediment-removal service

Crawler Vac cleaning with an inspection-led suitability and access plan.

Read technical summary

Topside-controlled floor suction removes sediment and small debris from suitable potable-water reservoirs. An initial ROV assessment determines suitability; a pilot and assistant perform Crawler Vac work with no human tank entry.

Evidence of maturity

Marketed service with a documented assessment and cleaning workflow; the inspected sources do not identify the installed crawler model or a configuration-specific acceptance certificate.

Commercial availability

Suitability, duration and quote follow ROV assessment of size, access, sediment and condition; an alternative method or no work may be appropriate.

Core features

Hatch-deployed Crawler Vac operated by a pilot and assistant
Supplier-described online operation with limited water discharge
Supplier-described sterilized equipment reserved for potable-water work
Final inspection/report and video document the work
Ridges, rivets, slopes, multiple levels, baffles and hatch/lifting access constrain suitability

ROV potable-water reservoir inspection

ROV reservoir-inspection service

ROV media and condition observations for utility maintenance planning.

Read technical summary

Hatch-deployed ROV visual inspection of accessible potable-water reservoir interiors without draining or human entry. One trained pilot works with the utility operator assisting near the hatch; video, photographs, temperature/depth observations and a report inform maintenance.

Evidence of maturity

Commercial service with named historical municipal operating evidence, including Cariboo’s 2024 103 Mile inspection without interrupting service. Visual observations do not replace emptied-tank engineering examination where needed.

Commercial availability

Available through Aquavision’s business inquiry route; accessible interior coverage and utility-operator assistance depend on the site.

Core features

One trained ROV pilot assisted by the water-system operator
HD camera and lights with temperature/depth observations
Supplier-described sterilized equipment reserved for potable-water work
Recorded media and inspection report with maintenance recommendations

Questions for a first conversation

Which tasks can use online ROV/Crawler Vac methods at this reservoir, and which require draining, confined-space entry or separate engineering assessment?
Crawler Vac suitability depends on floor geometry, baffles and hatch/lifting access. The supplier’s full-cleaning process explicitly takes the reservoir offline; Belcarra engineering reports identify conditions that need emptied-tank examination.

Aquavision describes a two-person ROV inspection team, with topside piloting and water-side handling, recording high-definition video, photographs, depth and temperature. Equipment is used only in potable-water reservoirs and disinfected. The service provides observations and reports; it does not by itself certify structural integrity or water quality.

Supports: Profile · reviewed questions.aquavision-services-decision-1.id
Aquavision's full reservoir-cleaning description explicitly includes draining, taking the reservoir offline and confined-space entry. Other wording advertises no service disruption. The specific cleaning method must therefore be agreed; the blanket existing claim that all inspection, cleaning and maintenance occur online is unsupported.
