When it comes to standards and compliance for public health and safety, Ven‑Tech Subsea’s dive team brings a tremendous amount of experience and can mobilize at a moment’s notice to respond appropriately in both routine and emergency situations. We proudly serve the Municipal, Industrial, and Private Water Storage sectors across British Columbia, Alberta, and Saskatchewan.
All of our potable water and reservoir services are performed in full compliance with — and often exceed — the standards set by the American Water Works Association (AWWA) for drinking water systems, including AWWA C652-19, and the NFPA 25 standards for fire suppression reservoir inspections. Our clients trust us to maintain the highest levels of safety, regulatory alignment, and technical accuracy on every project.
Experienced in confined space, deep water, contaminated environments, and zero-visibility diving for potable water storage systems.
Inspections, repairs, and maintenance performed while tanks remain full and operational, meeting AWWA standards and minimizing service disruptions.
Fully certified divers and equipment disinfected to AWWA C652-19 standards, delivering safe and compliant potable water solutions.
At Ven‑Tech Subsea, we deliver fully certified reservoir inspection, cleaning, and maintenance services for both potable water systems and NFPA-compliant fire suppression reservoirs. Our potable-grade commercial diving and ROV operations are supported by a technically skilled management team, including personnel with advanced qualifications in water quality, environmental science, and public health engineering. This depth of expertise allows us to consistently meet, and often exceed, the stringent requirements of AWWA C652-19 and NFPA 25.
All tasks are executed under written procedures, site-specific safety plans, and risk registers that ensure full alignment with CSA and provincial regulations. For every project, we offer real-time chlorine residual and turbidity monitoring, providing clear, traceable water quality data before, during, and after work. This helps water utilities, facility operators, and engineers maintain operational continuity and public health compliance.
Whether you’re managing a municipal drinking water reservoir, an industrial fire suppression system, or a remote storage facility, our teams can rapidly deploy throughout Western Canada, including British Columbia, Alberta, Saskatchewan, and Nunavut, as well as select regions of the United States.
From confined space robotic inspections to full-scale dive-supported cleanings, Ven‑Tech Subsea provides a scalable, turnkey solution tailored to the demands of modern infrastructure. Our services are trusted by municipalities, industrial operators, and engineering firms for their technical accuracy, transparent documentation, and unmatched safety performance.
Rigorous procedures to maintain water storage systems, ensuring compliance with regulatory standards.
Skilled divers handle underwater tasks, providing maintenance and emergency repairs in challenging reservoir conditions.
Advanced ROV technology for precise inspections and cleaning in high-risk, hard-to-reach environments.
Magnetic crawlers for efficient inspections and maintenance of steel tanks, evaluating welds and structural integrity.
Ven-Tech Subsea has extensive experience working with municipal and First Nations communities to ensure safe drinking water through potable reservoir cleaning and inspection. We follow AWWA C652-19 guidelines, which require thorough visual and structural inspections at intervals no greater than five years, as well as proper disinfection and monitoring.
Our potable-grade commercial diving services include:
Diver-led sediment removal (Reservoir Services)
Underwater video and photographic documentation
Chlorine residual and NTU turbidity testing
Biofilm removal and wall scrubbing (Reservoir Services)
Leak detection and minor underwater repairs
Inspection reports with detailed condition assessments
All divers and equipment are disinfected with a 200ppm chlorine solution per AWWA standards, and potable-only dive gear is used exclusively for drinking water facilities.
Industrial clients and engineering consultants across Western Canada trust Ven-Tech Subsea for NFPA 25-compliant fire reservoir services. Our certified divers inspect, clean, and maintain fire suppression reservoirs that serve oil refineries, pulp mills, logistics terminals, and government facilities.
NFPA 25 requires that tanks be inspected internally every 3–5 years and cleaned when necessary to maintain design flow rates and pump efficiency.
Our NFPA 25 dive services include:
Inspection of baffles, ladders, outlets, and intakes
Thickness measurement of steel tank walls (UT) (Reservoir Services)
Debris and sediment removal around intakes and suction points
Valve condition verification and functional checks
Detailed photographic and HD video records
Reports with remediation recommendations (Reservoir Services)
We also partner with engineering firms and EPCs for third-party validation or contractor verification of fire protection infrastructure.
