Conrady Consultant Services is a nationwide professional water storage tank inspection company specializing in ROV inspection, ROV water tank inspection, ROV pipeline inspection, other ROV tank inspection, underwater tank inspection, drained tank inspection, NFPA 22 and 25 fire water tank inspection. We do both drained inspection and underwater ROV inspection of all types and sizes of storage tanks except for petroleum products. We inspect inground, groundlevel, and elevated tanks constructed out of poured in place reinforced concrete, prestressed concrete, composite, welded steel, riveted steel, bolted steel, glass lined bolted steel, fiberglass, and hydropneumatic tanks. Since our ROV documents the water temperature throughout your tank from side to side and top to bottom, we determine whether or not your water storage tank has water stratification and evaluate if you need a water mixing system or the effectiveness of your existing water mixing system.

We are a husband and wife inspection team consisting of a Registered Professional Engineer (P.E.) and an assistant and we have no other employees and we do not subcontract inspections to others. Each and every one of our inspections are now and always have been done by us. For our underwater inspections we dove into the tanks until 2004 when we stopped diving and started exclusively using a Remotely Operated Vehicle (ROV).
We are an independent inspection company and do not use our inspection to try to sell you a maintenance program, or an unnecessary recoat or repair, or unneeded silt removal. Our inspections are honest and thorough and complete.
Since our team has personally done about 4,000 inspections throughout the US and in Canada and in Mexico in the 31 years we have been in business since 1982, and we personally inspect from 150 to 200 tanks each and every year, it is very likely that our team has inspected more tanks in the last 5 years than any other inspection company personnel have in their entire career. We teach classes and seminars on tank inspection, tank maintenance, tank operation, and tank design.
We specialize in routine every 5 or 3 year inspections and this is the vast majority of our work and income. We also do 1 year warranty inspections and pre and post cell phone antenna installation inspections. Since we only occasionally do critical phase, and final acceptance inspections, and do not do full time inspection of a tank during a rehabilitation, there is no reason for us to not be completely honest about the condition of your tank since we will not make any additional money from you for encouraging you to unnecessarily rehabilitate or repair or modify your tank. We will tell you what condition your tank is in, whether or not you need corrective actions, and in what time frame you should do these corrective actions. In other words, if your tanks need rehabilitation we will tell you so, and we will also tell you if you donít need to do anything. We wonít show you a few places of coating failure and corrosion and tell you that you need to recoat your tank and encourage you to hire us for inspecting the contractorís work during the rehabilitation. We make no more money from you after the initial inspection!
We are the only firm that specializes in tank inspections that we know of whereby a P.E. actually comes to your tank site or facility and personally inspects your tanks. Although our P.E. may not be registered in your state, and the inspection report may not be stamped or sealed with an engineering stamp, WE DO CARRY PROFESSIONAL LIABILITY INSURANCE and you do have the advantage of having an experienced and educated P.E. inspector instead of a technician who may not have a clue what to look for or what they are looking at.
We include the tank exterior in our inspections. Many ROV and commercial diving inspection companies do not include the tank exterior in their inspections!
Our Registered Professional Engineer (P.E.) has 37 years of tank inspection experience and has been on several AWWA committees/subcommittees including the AWWA D104 and D106 Committees for cathodic protection systems. We have been involved in the installation, testing, and repair of cathodic systems since sometime in the late 1980's. We are both are on the NFPA Technical Committee On Water Tanks.
Our education, experience and training has been specifically oriented to the inspection of water storage tanks. We have been intimately involved with the recoating, modification, and repair of countless tanks, as well as specification preparation, failure analysis, and warranty inspections.
Since 1976 we have been involved with the design, construction, installation, operation, maintenance and inspection of water storage tanks. Many steel and concrete tank manufacturers have brought us to their tank installations at each progressive stage of their tank construction so that we would see firsthand their construction methods and we were carefully instructed by these manufacturers what problems to watch for, and what conditions were actually problems, and what were not problems. We have been to many paint manufacturer facilities to learn how their paint products were manufactured, how they are applied, and what problems we might encounter during our inspections, such as application problems and methods to correct these problems, reasons for premature failure, amine blushing problems, reasons for adhesion loss problems, determination as to whether or not the tank should be recoated or repaired, determination as to whether or not a tank exterior can be overcoated, and also the determination as to the existence of lead primer material and the possibility of encapsulation of this material or if it must be completely removed.
We have been to many steel tanks as they have been recoated. We were at some tanks at the invitation of the painting contractor to watch their work so we were comfortable recommending them to others. We have been hired several times by engineers and tank owners as critical phase inspectors, even on some tanks which had a full time inspector, to inspect the contractor's work, perform wet sponge holiday testing and MEK rub tests, and ensure that the contractor was meeting the requirements of the specification. We have been hired several times to do final acceptance inspections of tanks that were just painted and were ready to be filled with water and placed into service, even on some tanks that were full time inspected by another company, to ensure that the full time inspector did not miss problems and that the contractor's work met the specification requirements. We have been hired many, many times to do warranty inspections on tanks that were newly constructed, or were recoated and/or repaired and were nearing the end of their warranty period to ensure that the contractor's workmanship was adequate and that no recoating or repairs were necessary and that the owner or engineer could completely accept the tank and release the contractor's bond.
We were hired to actually drive 130 miles down into mainland Mexico to determine and analyze why there were major problems with a new bolted steel tank installation.
We have provided expert witness testimony for legal disputes about water tanks.
We were hired to inspect a steel standpipe which was empty waiting for a final inspection after a recoat which had a stick of dynamite exploded in it to determine if any damage occurred to the tank and if it was safe to fill this tank and place it back into service. They said that they could hear the "BOOM" throughout the entire valley.
We have prepared recoat specifications and provided assistance to our clients throughout the bidding process, contractor selection, and recoat process.
Since we specialize only in tank inspections, and are not involved in other water, sewer, and road projects, and have 37 years of experience in this field, other engineering firms are comfortable and confident in our expertise and frequently use us as a consultant. We constantly modify our reports to make sure that they meet the expectations of our engineer clients. Because of this, we have very good relationships with the engineering firms who subcontract their tank inspections to us, refer us to their clients, or do joint inspections with us.
