We offer 3 different ways to inspect your WATER STORAGE TANKS and towers.
Remote camera inspection. Our most economical and popular method. we lower a camera into your Potable Water Tanks to get a look at underwater conditions including sediment levels while the tank remains in-service.
Remotely operated vehicle or ROV inspection is our second method. The ROV is motorized allowing it to swim to the rear of the tank. This method is recommended for larger facilities.
Diver inspection. Potable Water Divers are sealed in their own environment, then washed down with a 200ppm chlorine solution. This allows the diver to enter the water system and move around as needed to inspect, clean or make repairs.
Our Remotely operated Vehicle inspection is also popular for larger facilities. We maintain a feet of three ROV’s to meet our customer demands at any time. Our reports caver all required State and AWWA inspection points. Be deliver the completed inspection report back in a notebook/binder for convienient reference and storage.
DEEP TREKKER ROV
Diver inspections are our third method. Often used when specific inspection goals are required. Divers also perform inspections after tank cleanings. The diver is sealed in his own environment and washed down with a chlorine solution to meet all AWWA and EPA requirements. This allows the diver to enter the water system and move around freely.
Water Tank Inspection Diver
Water tank inspection and water tank cleaning is our specialty since 1997. Please visit our web site at www.ronperrin.us or www.watertankinspection.com for more information. For a free price quote call 817-377-4899.
Some people may not understand why I picked this strange shade of green for my blog. These photos may help explain. We still have an opening, if you are a qualified diver (see employment post) give us a call!
Multiple USEPA White papers have documented that bacteria, protozoa and even viruses can use the sediment that accumulates on the floor of water storage tanks as a habitat to grow and become a problem in water systems. One of these papers was published on June17, 2002. Titled
“Health Risks From Microbial Growth and Biofilms in Drinking Water Distribution Systems”
Many studies have identified microbes in accumulated sediments, including both pathogens and non-pathogens. These include bacteria, viruses, protozoa, algae, fungi and invertebrates. Opportunistic pathogens that have been detected, and can multiply in sediments, include Legionella and mycobacteria (van der Kooij, 2000). Some primary pathogens can also survive for some time in sediments. Hepatitis A virus survived more than four months in sediments at both 5/C and 25/C (Sobsey et al., 1986). Other opportunistic pathogens found in sediments include Pseudomonas fluorescens and Flavobacterium spp. (Berger et al., 1993). Sediments can also release nutrients into the water which stimulate biofilm growth downstream (LeChevallier, 1999b).
The paper explains there is steady inflow of bacteria, fungi, protozoa, algae, nematodes, and other microorganisms enter the distribution system.
We often find that some of the deepest sediment is found in the smaller storage tanks. Our cleaning service is priced right. We clean tanks from 3,000 to 30 million gallons. Give us a call at 817-377-4899 and we will give you a proposal designed for your specific tank.
It is amazing how many water utility professionals do not understand the threat of sediment build up in the interior of water storage tanks. Potable water tanks and towers accumulate sediment over the years they are in service. We often see tanks (weekly) that have never been cleaned. The EPA has documented that sediment in a storage tank may become a habitat for bacteria, protozoa and even viruses. Keeping your storage tanks clean should be a scheduled procedure for every water system. Unfortunately, the smaller water utility systems with fewer resources are where we see the most need. Tanks in smaller systems are much more likely to go longer between cleanings, or just never be cleaned at all. Check out our web site: www.ronperrin.com
Our crew is at our best cleaning and inspecting water storage tanks and towers.
If your tanks have not been inspected this year please call for a free quote. We offer diver, ROV or a lower cost underwater camera option. We are sure to have a comprehensive inspection that is right for you. Call today 817-377-4899.
Clean your water tanks. No mater how you do it Cleaning your water storage tanks is important. Soft sediment accumulations on the floor of your water storage tank can be an inviting habitat for bacteria, protozoa and even viruses. Keeping your tank clean will improve water quality, lower chlorine cost and reduce the chance of a RTCR violation.
Still not sure you need to clean your tank? Call us today to schedule a comprehensive inspection that will include an underwater video. See the floor of your tank on DVD.
