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.

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.

For the inspection you need at a price you can afford call Ron Perrin Water Technologies  1-888-481-1768

GST – Ground Storage Tank Inspection

EST – Elevated Storage 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 method and offer the most information for the lowest cost.   Sometimes circumstances may arise that prevent funds from being available.

In that case, follow these steps to safely inspect your own water storage tank to meet state standards.

There are safety concerns before you get started. The first step is to be sure the person assigned to climb any type of water storage facility is fit.  Obviously climbing a water tower is physically challenging, but even smaller ground type storage tanks can require an exhausting amount of physical effort to climb.

Make sure everyone who is working on elevated surfaces (any water tank or tower) has completed a basic OSHA approved course on working at height.  Employees who conduct work on elevated surfaces are exposed to fall hazards and are required to receive fall-protection training. If you are going to make entry into the tank you will also need to acquire confined space training.  Employees who work in confined spaces face increased risk of serious physical injury. Hazards involving a confined space include entrapment, engulfment, and dangerous atmospheric conditions. As a result, employees who conduct work within confined spaces must be properly trained.

Next, you need the right equipment. Starting with a full body safety harness with Fall Protection Shock Absorbing Lanyards. If you are going to enter the tank for an inspection, a multi-gas monitor to perform atmospheric testing prior to entering a confined space is required under OSHA’s 1910.134.  You will also need at least a three man entry team that includes a supervisor, entrant and attendee.

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.

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 view the interior.  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 Log

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.

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.
