Deep water intake clearing, conduits, and reservoir maintenance.
Public Utilities & Municipal Water Systems
Deep water intake clearing, aqueduct descaling, pump station de-silting, and reservoir maintenance.
Municipal drinking water plants, regional wastewater treatment facilities, and regional aqueducts depend on clean, uninhibited hydraulic flow to serve millions of citizens.
Chow Marine delivers NSF/ANSI 60 certified potable water cleaning and remote robotic inspection services that protect municipal infrastructure without contaminating treated water supplies or requiring extended service interruptions.
Our fleet of specialized subsea ROVs and long-reach pipe crawling robots inspect and decontaminate raw water intake pipelines extending kilometers offshore into Lake Ontario, Lake Erie, and the St. Lawrence River. Using high-thrust cavitation cleaners and zero-chemical thermal hydro-jets, we eradicate heavy zebra mussel encrustations while recovering all biological waste.
For wastewater treatment digesters, clarifiers, and primary aeration tanks, our heavy-duty industrial vacuum tankers and 40,000 PSI jetting heads rapidly remove calcified struvite scale, compacted grit, and hardened sludge blankets.
Potable Water Compliance
Full sanitization of all equipment, hoses, and diving gear using NSF-approved sodium hypochlorite solution.
Robotic Intake Ingress
Deployment of long-range fiber-optic crawler ROVs through shore wells to inspect and log intake pipeline geometry.
Cavitation & Jetting Clearing
Non-abrasive cavitation cleaning of intake screens and internal tunnel walls to restore 100% flow coefficient.
Bacteriological Clear Testing
Collaborative water quality sampling with municipal laboratory technicians before water line reactivation.

Emergency Intake Screen Clearing for Regional Water Facility
Emergency winter mobilization to clear severely choked offshore intake crib located 1.8 km offshore in Lake Ontario at a depth of 22 meters.
01
Are the cleaning methods safe for drinking water reservoirs?
add
Are the cleaning methods safe for drinking water reservoirs?
Absolutely. We use zero toxic chemicals. All tooling is sanitized to drinking water standards, and we utilize high-pressure pure potable water or mechanical cavitation for cleaning.
02
Can intake clearing take place without taking the water plant offline?
add
Can intake clearing take place without taking the water plant offline?
Yes. By utilizing twin-intake bypass procedures or diver-safe lockouts on specific intake cells, the utility can maintain continuous partial plant throughput during operations.
03
How do you handle heavy struvite deposits in municipal digester piping?
add
How do you handle heavy struvite deposits in municipal digester piping?
Struvite is notoriously hard (comparable to concrete). We utilize specialized carbide-tipped rotary hydro-demolition nozzles operating at 36,000 PSI that shatter the crystalline struvite without damaging the ductile iron or PVC piping.
