Potable Water Diver Video

Some of our older video’s ate still the best.  This great video from 2009 shows a diver and a Remotely Operated Vehicle inspecting a water storage tank.  It also lets you see divers cleaning sediment off the floor of a tank in the video posted below.

Potable water divers vs ROV

While some water utility operators prefer to have their tanks inspected by Certified divers others prefer the safer method of using an underwater camera or remotely operated vehicle (ROV).

Video Ray Remotely Operated Vehicle

It is true the diver can deliver a more detailed inspection, it is also true that is usually at a much higher cost both in money and risk to human life.  The diver needs at least two tenders to safely enter a confined space, while a field technician with an underwater camera sends his camera into harms way.   Our company employs all three methods each has its advantage and disadvantage.  The remote camera is by far our most popular way to inspect water storage towers, due in great part to the low cost.

The remote underwater camera gives you a lot of information for the money, allowing you to see a good portion if not all of the intirior roof and floor area of most tanks and towers under 500,000 gallons.  Our next step up from the Remote Camera is a Remotely Controlled Vehicle (ROV).  This is a unit that has an underwater camera and motors with props that allow it to go to the rear of large tanks or look a a specific point.  Be carful with deceptive contractors that try to pass off a remote underwater camera as an ROV saying it stands for Remotely Operated Video.

Both the remote underwater camera and the ROV put the equipment not the person into the confined space containing potable water.  The diver inspection requires a much larger operation.  The diver can use a remotely controlled underwater video system that is being viewed and recorded by the top side dive team or he can use a diver held camera that is actually a camcorder in an underwater housing.  All the equipment he is using and wearing should be purchased for and only used in potable water.  When selecting a ROV or diving contractor you should do your homework.  Check out their main web site and see what kind of work they are promoting. If the Web site is focused on off shore activities, the company may only be working in potable water as a sideline. Further investigation may show them using the exact same identifiable  gear in potable water storage tanks that they use in muddy canals or even waste water.  A little online research will go a long way when you want to determine who to trust the safety of your water system to.  Microbiological contamination is a real concern when allowing access to your potable water storage tanks.  For more information on bacteria and other contaminants visit my Water Project blog at www.ronperrin.us  scroll down to the contaminate article or watch the bacteria reproduction video.

“Inspecting & Cleaning Potable Water Storage”  By Ron Perrin

Bacteria, protazoa and even viruses can find the sediment in the floor of a water storage tank an inviting habitat. The sediment can allow many microbiological contaminates to get a foothold in your system, grow and create a larger problem. The EPA has determined that microbiological growth in distribution systems is a threat to public health.

If you cant get your supervisors, directors or council members to look at this web site, now you can order the book and put it in their hands.

These photos make the case- Inspecting & Cleaning Public water supplies should be a top priority.

Dewatering a Tank to Inspect or Clean it can be a nightmare!

Why is de-watering a nightmare?  Once a water storage facility is drained, the loose sediment begins to dry and harden.  Multiple inches of sediment that had been is a semi- liquid state and could easily be removed by a dive team, may be reduced to less than a ½ inch of hard, clay like buildup that must be scraped from the floor of the tank.  The painted surface of the tank floor is better off if the sediment is removed before it is allowed to dry and get hard.

The best method for cleaning your tank is to use a qualified and experienced dive team.

 Removes all loose sediment

 Will not damage tank

Little if any down time, because the water is not drained the tank goes back in service quick

Small tanks can be cleaned in hours instead of days.  Large tanks can be cleaned in days instead of weeks.

Once underwater, the diver carefully works off the ladder to clean a spot to stand.

He then works slowly outward from that spot, careful not to stir up the sediment and Crate turbidity.  This is one of the big differences between a professional tank cleaning crew and a commercial dive crew that has been trained to work offshore.  They tend to throw everything they need into the tank, and once the sediment is disturbed, it becomes a big cloud in the water. This turbidity has a negative effect on the water system.  The dirty/cloudy water can then get into the system causing complaints.  In addition to that, the tank can never really be cleaned on that day because the sediment that is suspended in the water causing the cloudy and high turbidity condition will eventually settle down to be another layer of sediment on the floor of the tank.  There is an art to cleaning a potable water storage tank without creating turbidity.

In-Service Cleaning of Potable Water Storage Tanks

 

Photo: Sediment being removed from Potable Water Storage Tank.

        The American Water Works Association recommends that tanks be cleaned at least every three years.  Recent focus on pharmaceuticals in water systems have made more people than ever aware of contaminates that may be lurking in their water supply.   Although pharmaceuticals in drinking water may be in the news the real threat is random bacteria and cryptosporidium spores.

The Threat of Bacteria-

Countless kinds of bacteria can make their way into a public water supply.  Chlorine and other treatment methods are our first line of defense.  When potable water storage tanks are clean small amounts of bacteria that survive the treatment process cycle through the system undetected and harmless due to the small quantity.  Sediment in the tank can capture and harbor these small amounts of bacteria.  The bacteria can start to grow hidden from chlorine deep in the sediment.  Chlorine can even be overwhelmed and depleted if a nitrate eating bacteria is collected.   As the bacteria continues to grow in the sediment month after month and year after year the threat to public health grows.       

  The Threat of Cryptosporidium

The threat of cryptosporidium outbreak is even greater with sediment in the floor of a water storage tank.   Again Sediment can harbor bacteria, cryptosporidium and other contaminates.  The best defense to insure a protozoa like  cryptosporidium will not take up residence in your water storage system may be to keep the tanks free of sediment.  In the Spring of 1993 over 100 people died as a result of a cryptosporidium outbreak that was directly associated with the Howard Avenue Water Purification Plant.  This was the largest water born disease ever documented in United States history.  It is estimated that over 400,000 people became ill with diarrhea.  

Due to the fact that cryptosporidium is a protozoa parasite with a thick outer shell it is highly resistant to disinfectants such as chlorine.  The best defense to ensure it will not inhabit your water system may be to make sure your water tanks remain sediment free.  This will remove and habitat that small amounts bacteria or protozoa could lodge and grow in, Preventing possible public health problem in the most simple way.  Keeping water storage tanks clean.

Health risk of sediment build up in tanks-

Yearly inspections of your potable water storage tanks is the best way to keep up with the sediment levels in your tank.   A good inspection of a potable water storage tank should allow the customer (the water Utility) to see the floor of the facility.  Using a Remote video camera or diver held camera the inspection often reveals 2 to 3 inches of sediment and sometimes much more. Keeping your water storage tanks clean may be one of the most overlooked maintenance procedures in the water industry.  Out of sight and out of mind, sediment in the bottom of your water storage tanks is never seen and rarely thought of.   The sediment that builds up in almost all potable water tanks can be a habitat for bacteria and other contaminates.  Bacteria can get a foothold in the sediment  out of reach of the chlorine entering the tank. Hidden in the sediment the bacteria can then grow and flourish creating a health risk. A nitrate eating bacteria can even deplete your chlorine levels leaving you at even greater risk. Removing the sediment and keeping your tank clean is the best way to maintain a healthy water system.  Divers wearing a dry suit are sealed in their own environment, they are then washed down with a chlorine solution meeting all State and AWWA requirements.  The divers may then enter the water system and vacuum out the sediment.  Everything that is loose is removed, allowing the chlorine or other treatment chemicals entering the tank to effectively do its job. This is a much more effective method than the traditional buckets and shovels.  We are able to remove ALL loose sediment without scraping shovels on painted surfaces.  In addition thereIs minimum water loss with our method, you do not need to DRAIN YOUR TANKS.         Call today to learn how we can save you water, time and money while helping you maintain the healthiest water system possible.
