Florida Tank Inspection

April 24, 2010 Leave a comment

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.

Ron Perrin Water Technologies offers Qualified Inspections meeting all Florida requirements for potable water tank inspections.  Using underwater cameras, ROV’s or divers we are able to inspect 100% of your facility without any disruption in service.

If your tank is out of compliance for the cleaning requirement our professional potable water divers are available to remove all sediment from your water storage tanks at competitive prices.

Florida Inspection Rule:

62-555.350 Operation and Maintenance of Public Water Systems. (1) Suppliers of water shall operate and maintain their public water systems so as to comply with applicable standards in Chapter 62-550, F.A.C., and requirements in this chapter.   (2) Suppliers of water shall keep all necessary public water system components in operation and shall maintain such components in good operating condition so the components function as intended. Preventive maintenance on electrical or mechanical equipment – including exercising of auxiliary power sources, checking the calibration of finished-drinking-water meters at treatment plants, testing of air or pressure relief valves for hydropneumatic tanks, and exercising of isolation valves – shall be performed in accordance with the equipment manufacturer’s recommendations or in accordance with a written preventive maintenance program established by the supplier of water; however, in no case shall auxiliary power sources be run under load less frequently than monthly. Accumulated sludge and biogrowths shall be cleaned routinely (i.e., at least annually) from all treatment facilities that are in contact with raw, partially treated, or finished drinking water and that are not specifically designed to collect sludge or support a biogrowth; and blistering, chipped, or cracked coatings and linings on treatment or storage facilities in contact with raw, partially treated, or finished drinking water shall be rehabilitated or repaired. Finished-drinking-water storage tanks, including conventional hydropneumatic tanks with an access manhole but excluding bladder- or diaphragm-type hydropneumatic tanks without an access manhole, shall be checked at least annually to ensure that hatches are closed and screens are in place; shall be cleaned at least once every five years to remove biogrowths, calcium or iron/manganese deposits, and sludge from inside the tanks; and shall be inspected for structural and coating integrity at least once every five years by personnel under the responsible charge of a professional engineer licensed in Florida. Dead-end water mains conveying finished drinking water shall be flushed quarterly or in accordance with a written flushing program established by the supplier of water; additionally, dead-end or other water mains conveying finished water shall be flushed as necessary whenever legitimate water quality complaints are received.

Do your own Potable Water Tank inspection

March 21, 2010 1 comment

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, or 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.

Check the vent screen as it 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, so do not use stainless steel – it may seem like an upgrade, but it won’t last any time at all.

Vent Structure

Next check the level of the sediment on the bottom of the tank floor.  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 sediment depth & what it looks like, and make sure there are no insects, birds or other contaminants 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 inside, 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.

The proper safety equipment & training is the key to performing a water tower inspection safely.

Proper Safety Gear Must Be Worn

Get a copy of the Texas State Rules  for water tank inspection directly from the TCEQ here:

TCEQ 290.46 go to : Chapter 30,   TAC §290.46(m)(1)(A)

The State Form is also available HERE:

Texas Commission on Environmental Quality Tank Inspection Form

Some other states follow AWWA recommendations. Here are the main components that are required to be inspected annually in Texas, and  should be included in any potable water tank inspection.

Foundation: settling, cracks, deterioration

Condition of  Exterior Coating: rust, pitting, corrosion, leaks

Water Level Indicator: operable, cable access opening protected

Overflow Pipe: flap valve cover accessible, operable, sealed

Access Ladder: loose bolts or rungs

Roof: low spots for ponding water, holes along seams, rust

Air Vents: proper design, screened, sealed edges and seams

Cathodic Protection Anode Plates: secured and sealed

Roof Hatch: proper design, locked, hinge bolts secured, gasket

Interior inspections should include:

Condition of  Interior Coating : Check for rust, corrosion, blistering & scaling.

Water Quality Check for:

Insects in the tank both on the surface of the water and on the interior floor.

Floating debris

Sediment levels on the interior floor – (Sediment can be a habitat for bacteria & other contaminants).

Is your tank a HydroPressure Type Tank?

Pressure Type Tank

Check Operational Status: pressure release device, pressure gauge, air-water volume device

In Texas Pressure  Type Tanks that are large enough to have an inspection port are required to be inspected annually.

They are also required to be opened up and have the interiors inspected at least once every five years.

All inspection reports performed in Texas should be kept on file and available for TCEQ review for five years.

This should help you gat started on your potable water tank inspections.  My 157 page book is another great resource – it includes tank inspection and cleaning methods as well as state rules and common contaminants that are found in our nations water system.  It is available HERE: “Inspecting & Cleaning Potable water storage”

We have the proper training, inspection and safety equipment to safely deliver you the most information for the least cost.

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 a Florida

licensed engineer to inspect a water storage tank.  For service in Florida see: http://www.floridatankinspector.com

Potable Water Tank Inspections

November 17, 2008 1 comment

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.

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.

Warranty Inspections

November 17, 2008 Leave a comment

Warranty Inspections:

 

Our inspections are a valuable tool when used while your tank is still in warranty after construction or after a painting contract has been completed.  Allowing a painting contractor to perform his own warranty inspection is a little like hiring a fox to guard a hen house.  If he just did the painting it is in his best interest to tell you everything is ok.

 

Good or bad our report will show you what is going on inside and outside your tank, we cover it top to bottom.

 

Painting contractors offering low cost inspections are not much better.  It is their job to find work so they cam make tens or hundreds of thousands of dollars contracting a paint job on your water tank or tower.

 

We do not paint tanks.  Ron Perrin Water Technologies inspects and cleans water storage tanks & towers.   We are the perfect company for a third party inspection.  Have you been told your paint is too thin?  We can take DFT (Dry Film Thickness Test) reading on your tank from top to bottom, upon request.  Our photos show you what is going on.  If you have peeling paint or surface corrosion a photograph is truly worth a thousand words.

If you do not have a problem you may be able to go several more years before investing in an expensive painting contract.  Either way the information provided in our annual inspection reports is worth its weight in gold and meets all requirements for your

TCEQ required annual inspection.

 

Call today our inspection reports start at only a few hundred dollars.

 

We include:

A detailed written report including digital photography

Narrated underwater video documenting interior conditions and sediment levels

Dry Film Thickness Testing  (DFT) in nine locations unless more are requested.

One Million Dollars general liability policy, workers comp., and vehicle insurance.

The Importance of Cleaning Water Storage Tanks

July 24, 2008 Leave a comment

Safe municipal drinking water has been with us so long that it is easy to forget that even today the World Health Organization estimates that over a billion people do not have access to clean drinking water.  Administrators who manage water systems know that the luxury of having safe drinkable water comes at a cost.  It is a constant struggle to maintain the aging infrastructure and keep up with the most effective water treatment options.

Although water treatment chemicals and treatment methods have taken great leaps forward over the years there is still a basic element of sanitation in our water systems that is often overlooked.  Simple sediment build up in the bottom of a water storage tank can undermine the best plans and most advanced chemical treatments. In a municipal water system sediment builds up over time.  With 10 years of inspecting water storage tanks behind us and thousands of tanks inspected, we have found that three inches of sediment or less is common across Texas, but we have found some tanks with many times that and even multiple feet of sediment.

Keeping your water storage tanks clean may be one of the most overlooked maintenance procedures in the drinking 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 like cryptosporidium that devastated the city of Milwaukee in the spring of 1993.
