Now we can add a brain-eating amoeba to the list of contaminants that can be in tank sediment

Sediment being removed from the floor of a potable water storage tank by a dive crew.

Removing sediment from the floor of your water tanks and towers may also be removing the habitat that allows bacteria, protozoa and viruses from getting a foothold in your distribution system.   Now we can add a brain-eating amoeba to the list of contaminants that the sediment on the floor of your water storage tank can support.

September 16, 2013, NBC News reported: “Deadly brain amoeba infects US tap water for the first time”. The death of a 4-year-old boy near Violet, LA., was linked to the Naegleria fowleri amoeba. The child had been playing on a backyard slip-n-slide that used water from the St. Bernard Parish water system, that was later found to be contaminated with the amoeba. “Tests show it’s present throughout the water supply system in St. Bernard Parish, directly southeast of New Orleans.”

According to the CDC:  “Naegleria fowleri (commonly referred to as the “brain-eating amoeba” or “brain-eating ameba”), is a free-living microscopic ameba, (single-celled living organism). It can cause a rare and devastating infection of the brain called primary amebic meningoencephalitis (PAM). The ameba is commonly found in warm freshwater (e.g. lakes, rivers, and hot springs) and soil. Naegleria fowleri usually infects people when contaminated water enters the body through the nose. Once the ameba enters the nose, it travels to the brain where it causes PAM, which is usually fatal. Infection typically occurs when people go swimming or diving in warm freshwater places, like lakes and rivers. In very rare instances,Naegleria infections may also occur when contaminated water from other sources (such as inadequately chlorinated swimming pool water or heated and contaminated tap water) enters the nose. You cannot get infected from drinking water contaminated with Naegleria.”

The CDC also tested nearby DeSoto Parish Waterworks Dist. #1 because it was the near the site of an infection that happened in 2011 from non-potable water (lake or river, etc.). On October 8, 2013, The CDC confirmed the presence of the rare amoeba in five locations in DeSoto Parish Waterworks Dist. #1.

Heat is also a factor, an increase in only ten degrees can double the speed of bacteria growth. As record high temperatures become more common in summer months we see that keeping water distribution tanks free of sediment build up may be more important than ever before. Removing the sediment from your water tank may prevent a disaster before it can ever start.

We offer potable water tank inspections and cleaning.

Potable Water Diver

Potable Water Diver

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 and tower inspection and meeting all AWWA guidelines.  Our inspections cover over 30 inspection points.  Digital photography documents the condition of your tank, and our narrated underwater video lets you see first-hand what the inside roof walls and floor areas of the tank look like.

.

For those experiencing an EPA total coliform violation, our underwater inspections are a perfect place to start assessing your problem. Should accumulated sediment be found in the tank, our potable water dive crew can offer a cleaning solution that may be the only step needed to satisfy the Revised Total Coliform Rule requirement to take action.  Accumulated tank sediment can be a safe habitat for bacteria, protozoa, viruses and other contaminants.  Removing the sediment is often the only step required to comply with the Revised Total Coliform Rule**, in fact, our customers tell us time after time that their chlorine costs were significantly reduced after the tank was cleaned.

.

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.

.

We are here to help you get it done!  We offer the most choices for your inspection needs:

*Remote underwater camera (drop camera)

*ROV – Remotely Operated Vehicle (specially designed and only used in potable water)

*Diver inspection – For the most detail

*Basic state requirements covered with, or without, photos to meet budget needs

.

We have served over 500 water utilities since 1997.  Our customers include municipalities, prisons, universities and military bases.  They all have one thing in common – they wanted comprehensive documentation about the status of their water tank, with no water loss and no disruption in service.

**On February 13, 2013, EPA published in the Federal Register the revisions to the 1989 TCR.  EPA anticipates greater public   health protection under the Revised Total Coliform Rule (RTCR) requirements.  The RTCR:

  • Requires public water systems that are vulnerable to microbial contamination to identify and fix problems; and
  • Establishes criteria for systems to qualify for and stay on reduced monitoring, which could reduce water system burden and provide incentives for better system operation.

Florida Rule Requires Tanks to be inspected and cleaned at least once every five years

Our company can help your Florida Utility meet the requirements for water tank inspection and cleaning under 62-555.350 with no or little disruption in your water service.  For more information see our main web page at http://www.ronperrin.com for a free quote call 888-481-1768 or fax a list of your tanks to 817-246-1740. The Florida standard is the most aggressive in the country requiring all potable water storage tanks to be cleaned and inspected by a licensed Florida P.E. at least once every five years.  The rule also requires some tanks at water processing plants to be cleaned every year. Read more here: 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. ——— Serving the Midwest & Southeast U.S. Ron Perrin Water Technologies is ready to work!
