Florida Tank Inspection
In August 2003 the state of Florida set a high standard for the inspection & cleaning of potable water storage tanks. Under FDEP 62-55-350 each of the states potable water storage tanks must be inspected and cleaned at least once every five years. The FDEP allowed a grace period until August of 2008 before any enforcement action was taken.

What we do is really amazing-
Keeping tanks and water towers clean makes sure that bacteria, protozoa or even viruses don’t get a foothold in the water system. These contaminates can find sediment in the floor of a water storage tank or tower an inviting habitat where they can hide, grow and even thrive. Keeping the floor of water storage tanks clean reduces the risk of waterborne contamination in public water systems.

Potable Water Tank Inspections
Since 1997 Ron Perrin Water Technologies has served the water utility industry providing state of the art inspections with remote underwater cameras. Our inspection reports are the best in the industry covering all STATE REQUIREMENTS for water tank & tower inspection and meeting all AWWA guidelines.
Click here for more information about Potable Water Tank Inspections
Our Web site about Potable Water Tank Inspections
or go to www.PotableWaterTankInspection.com
We cover over 30 inspection points. Our digital photography documents the condition of your tank, our narrated underwater video lets you see first hand what the inside roof walls and floor areas of the tank look like.
We offer the most choices for your inspection needs,
* Diver inspection for the most detail
* ROV – Remotely controlled underwater vehicle
(specially designed for potable water use)
* Remote underwater video camera
(our most popular inspection, includes digital photos & narrated underwater DVD for the lowest cost).
* Basic inspection- no video no photos. To meet state regulations for minimal cost.
Remotely controled vehicle
If there is a deep sediment build up we offer a underwater cleaning service. Using certified divers and special equipment we are able to remove the sediment in the floor of the tank with minimal water loss and no disruption in service. Unlike other diving companies who make their money offshore and work in the water utility industry part time, serving water utilities is 100% of our business!
Our gear is purchase for and only used in potable water.
Diving in potable water is an art. Unlike offshore divers, potable water divers must be able to enter the water system without disrupting sediment on the floor of the tanks, Our divers are sealed in a dry suit so no part of their body touches the water. They are then washed down with a 200ppm chlorine solution to meet AWWA and state standards. The diver is then free to go into the confined space inside the water storage tanks, underwater the diver can do a more detailed inspection or clean the loose sediment from the floor of the tank. Visit www.ronperrin.us to see video of divers inspecting & cleaning waterstorage tanks.
We have serviced over 500 customers that include municipal governments, utility districts towns, communities, prisons, military bases and universities. Our customers all have a few things in common they want the most information for the lowest cost with no disruption in there water system.

The EPA is considering New Rules for tank Inspection & Cleaning
On July 14th 2010 the The U.S. Environmental Protection Agency Posted this notice under / Proposed Rules
2. Storage Tank Inspection and Cleaning
EPA requests comment on the value and cost of periodic storage tank inspection and cleaning . There are instances of storage tanks being the source of waterborne disease outbreaks at PWSs. In December 1993, aSalmonella typhimurium outbreak in Gideon, Missouri resulted in over 600 people affected by diarrhea, 31 cases of laboratory-confirmed salmonellosis and seven deaths of nursing home residents who had exhibited diarrheal illness (four deaths were confirmed by culture). The larger of the two storage tanks had a breach in the roof hatch that allowed pigeon droppings to be carried into the tank and likely accumulated in the several inches of sediment. This contaminated sediment, more than likely, was pulled into the distribution system by a flushing program that drained the tank (Clark et al. 1996). Salmonella typhimuriumwas isolated from the sediment of one of the towers, and tap water tested positive for fecal coliforms (CDC 1996). In March 2008, Alamosa, Colorado (with a population of about 9,000 people) experienced a waterborne disease outbreak associated withSalmonella. The report released by the Colorado Department of Public Health and Environment (Falco and Williams 2009) indicated that the outbreak resulted in 442 reported cases of illnesses, 122 of which were laboratory confirmed, and one fatality. The State epidemiologist estimated that a total of 1,300 people may have been ill. Two storage tanks in Alamosa had several inches of sediment and breaches; one tank had breaches large enough for birds and animals to enter. Some of the key factors that contributed to these two outbreaks include significant levels of sediment (several inches to feet) and the presence of breaches of the integrity of the storage tank. Sediment accumulation occurs within storage facilities due to quiescent conditions which promote particle setting. Over time sediment continues to accumulate in a tank, even if the finished water is consistently treated tobelow 0.1 nephelometric turbidity unit(NTU). For surface water systems, it isnot uncommon to have 1⁄4 to 1⁄2 inch or more of sediment accumulate after two to three years (Kirmeyer et al. 1999).
While there are no turbidity regulations for ground water systems (except for ground water under the direct influence of surface water (GWUDI)), the levels of turbidity can be significant in the water pumped from an aquifer. Sand particles, if allowed to accumulate, provide pore spaces that house diverse populations ofbiota (which may include pathogenic microorganisms) (Kirmeyer et al. 1999; van der Kooij 2003). Periodic high flows in the storage tank may scour, stir up, and suspend the sediment (along with entrapped bacteria and pathogens) and carry it into the distribution system, with greater accumulation of sediment being a more significant concern. Other water quality problems associated with sediment accumulation include increased disinfectant demand and disinfection byproduct formation. The storage tank’s vulnerability to contamination increases when breaches of the storage tank allow insects, animals, and birds and their associated diseases to enter. Contamination from bird and other animal excrement can potentially transmit disease-causing organisms to the finished water. Waterfowl, for example, are known carriers of many different waterborne pathogens including Vibrio cholerae(Ogg et al. 1989). Based on the potential public health implications associated with poorly maintained storage tanks (e.g., as indicated by significant sediment accumulation and breaches), EPA is interested in receiving comments and supporting information regarding the state and condition of tanks that have been cleaned and inspected, costs of storage tank inspection and cleaning, and how public health can be better protected. EPA requests information on whether there are States that recommend or require periodic inspection and cleaning of storage tanks. If so, what are the requirements, the frequency of inspection and cleaning, and how successful are they? Are inspections and cleaning done by individual PWSs or by contractors?

Water Tank Inspector
We are adding a Registered P.E. to our staff to meet water tank inspection requirements in Florida. Our search for the best qualified P.E. has allowed us to have contacts with Professional Engineers in most states. If you require a Professional Engineers Evaluation of your water storage tank please contact us. Provide us with a scope of work to be preforemd or we will assist you in developing you scope of work request so you get the inspection you need.
Ron Perrin Water Technologies has provided the best Non-Engineering visual inspection reports on potable water tanks since 1997. Or inspections document all AWWA and state required inspection points with digital photos and underwater video, professionaly narrated and divifered in a binder that incluces a certification of inspection, printed report and the video on a DVD format.
The underwater video is available from three different sources. Our most popular is the most remote under water tank inspection camera, next our Remotely Operated Vehicle (ROV) provides more information on larger facilities and if needed we can deploy a potable water diver. Our non-engineering inspections are the best way to meet annual visual inspection requirements required by some states.
When a more comprehensive report is required our seasoned potable water tank inspectors work under the supervision of our PE to safely collect the information needed while the water system remains in service.

Potable Water Tank Cleaning
Check out www.potablewatertankcleaning.com for more information about cleaning potable water storage tanks. Cleaning potable water storage tanks & towers removes the soft sediment from the floor of the tank that can be a habitat for bacteria and other contaminates. It is very important that all equipment be purchase purchased for and only used in potable water. Cross contamination is a serious threat to any water supply. In addition to having dedicated equipment all equipment entering the tank should be washed down with a chlorine solution as recommended by the AWWA.

Do your own Potable Water Tank inspection
In Texas potable water tanks are required to be inspected inside and out each year. Of course that is our business and we are sure we have the best inspection, offering the most information for the lowest cost. But sometimes no matter how much we offer and no matter how little we offer it for the funds may not be available.
In that case follow these steps to safely inspect your own water storage tank to meet state standards.
Inspection Technician on tower
Check the vent screen, that is the most common problem we see day after day. The chlorine & other treatment chemicals used in potable water are very hard on steel mesh screens, do not use stainless steel, seems like an upgrade but wont last any time at all.
Vent Structure
Next check sediment levels. If you don’t have an underwater camera handy you should drain the tank at least down to the level you can see the sediment on the floor, make a note of the depth & what it looks like, make sure there are no insects, birds or other contaminates in the tank. DO NOT ENTER the tank. If you need to make entry into the tank you should follow all Confined Space Entry protocols including having at least a three man trained team. This is really important! Chlorine gas can form above the water line in potable water storage tanks that have been treated with chlorine, in addition to that corrosion on the steel can deplete oxygen levels in the tank making a deadly combination. Our crews go in on their own air to dive the facility or use a remote camera to make entry we NEVER ENTER THE TANK alone or unprotected.
If you choose to use an underwater camera to get a look make sure it is purchased for and only used in potable water. Cross contamination is a serious issue that you need to be aware of! Visit our other blog at www.ronperrin.us for more information on water storage tank contamination.
If You are inspecting a tank or tower with a ladder be sure to have the fall protection equipment you need to get the job done safely.

My book is a great reference point for state rules and requirements.
The State of Florida is one of the only states if not the only one that requires you be a Florida
licensed engineer to inspect a water storage tank. The City of New York is one of the few if not the only municipal government in the U.S. that requires annual water tank inspections their requirements are listed below.
The City of NEW YORK Requires The Following:
§141.07 Building Drinking Water Storage Tanks
(a) Applicability. The owner, agent or other person in control of a building which has one or more water
tanks used to store potable water which is distributed as part of the building’s drinking water supply
system shall comply with the provisions of this section. This section does not apply to the domestic hot
water system.
(b) Inspection Requirements. The owner, agent or other person in control of a building shall have the
water tank inspected at least once annually. The inspection shall include the examination of the general
condition of the tank, including but not limited to the condition of overflow pipes, access ladders, air
vents, roof access hatches and screens. The interior and exterior of the water tank and its sealed edges and
seams shall be inspected for evidence of pitting, scaling, blistering or chalking, rusting, corrosion and
leakage. Inspection of sanitary conditions, including the presence of sediment, biological growth,
floatable debris and insects in the tank and rodent or bird activity on and around the tank, shall be
performed. The inspection shall include sampling of the water in the water tank to verify the
bacteriological quality of the water supply in compliance with Subpart 5-1 of the State Sanitary Code.
Sample results shall be reported by a State certified laboratory equipped to analyze drinking water, in
accordance with the latest edition of the Standard Methods for the Examination of Water and Wastewater,
published jointly by the APHA, the AWWA and the WEF.

Inspecting & Cleaning Potable Water – THE BOOK is Here!
New book is now availble :
INSPECTING & CLEANING POTABLE WATER STORAGE
By Ron Perrin
A reference mauual for Water Utility Managers & Directors.
Are you a water utility manager having trouble funding the tank inspections & cleanings you need? This book is for you!
Over time sediment builds up in all water storage tanks. This book shows you what it looks like when it is removed from water storage tanks and towers. If a picture is worth a thousand words these full color photos give you a thousand reasons why potable water storage tanks should be inspected and cleaned on a regular basis. Chapters cover, state rules, contamination found in potable water, inspection methods and cleaning methods.
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.
