9/11 Memorial Pools - A Look at the Reflecting Pools

As the 20th anniversary of the attacks on September 11th approach, we take a moment to look at the 9/11 Memorial and the two reflecting pools that mark the footprint of where the Twin Towers once stood.

We are now looking back at a point in history that occurred before approximately 28.5% of Americans were ever even born. There are many memorials for the victims of 9/11, but none clearly encapsulate the raw emotions of absence the way the 9/11 Memorial does.

A look at the two reflecting pools at the 9/11 Memorial

Two reflecting pools mark the exact place of the World Trade Center and stand as a permanent place of remembrance. Both pools commemorate the names of nearly 3,000 killed in the attacks on September 11, 2001 and the World Trade Center bombing of February 26, 1993. Each of the victims names are inscribed on bronze parapets surrounding both of the memorial pools.

The two pools at the 9/11 Memorial have attracted millions of visitors each year since it first opened.

It’s hard to believe that two decades have gone by since the day happened that would forever change the course of our modern history. 9/11 is a moment in time that will live in as much infamy as December 7th (the attack on Pearl Habor), perhaps even more so in our generation. September 11th is important to people, and the memorial embodies what it means not only to New Yorkers who were first-hand witnesses, but to Americans who watched the events of September 11th unfold live on television.

The mourning and sorrow the nation still feels even twenty years later is evident in the amount of visitors the 9/11 Memorial draws each year. The memorial site was built to remember the victims as well as those involved in the rescue and recovery efforts.

‘Reflecting Abscence’ – The 9/11 Memorial Pools Commemorating The Victims of the September 11th Attacks

Why did they choose reflecting pools for the memorial site?

Tracing their roots back to the ancient Persian gardens, reflecting pools have been a time honored traditional memorial structure and a water feature typically found in gardens and parks. One of the most iconic reflecting pools is at the Lincoln Memorial in Washington D.C. Most reflecting pools are shallow vessels and can range in size from as small as a bird bath to as large as a major civic center water feature like the one found at the 9/11 memorial site.

The 9/11 Memorial Design Competition

An open competition for designing the memorial site drew 5,201 entries from 63 countries. The thirteen-member jury chose eight finalists on November 19, 2003.

At a press conference held at Federal Hall National Memorial on January 14, 2004, the final design for the 9/11 memorial was revealed to the public. Israeli-American architect Michael Arad of Handel Architects and landscape architecture firm Peter Walker and Partners concept ‘Reflecting Absence‘ was chosen as the winning design. Their design consisted of a forest with two large, recessed pools that represent the Twin Towers’ footprints.

The deciduous trees (swamp white oaks) form informal clusters, clearings, and groves when arranged in rows. The park is located above the Memorial Museum, at street level. The names of the victims of the attacks (including those from the Pentagon, American Airlines Flight 77, United Airlines Flight 93, and the 1993 World Trade Center bombing) are inscribed on the parapets surrounding the waterfalls.

‘Reflecting Absence’ consists of two 1-acre pools. The structures are the largest man-made waterfalls in the United States. Both pools symbolize the loss of life and the physical void left by the attacks. The dual waterfalls are meant to drown out the sounds of the city, and create a peaceful haven of remembrance for what was lost.

The names of the victims of the September 11th attacks are engraved into 152 bronze parapets on the North & South pools.

Remembering those who were lost

On 152 bronze parapets on the memorial pools, the names of 2,983 victims are inscribed: 2,977 killed in the September 11 attacks and six killed in the 1993 World Trade Center bombing.

The two reflecting pools at the 9/11 Memorial

The North and South Fountains at the 9/11 Memorial have combined recirculating systems that pump up to 26,000 gallons of water per minute non-stop every day of the year. The water flows over the memorial’s two deep reflecting pools’ walls before being recirculated into catch basins.

The September 11 Memorial utilizes a method of keeping water constantly flowing from a 30-foot drop regardless of the weather New York City gets. The pool is engineered in such a way so that it’s reflective qualities and the sound of falling water remain consistent through the changing seasons.

The Builders of The 9/11 Memorial

You may not know this, but Delta Fountains are the pool builders responsible for building the 9/11 Memorial pools. Joe Petry, President of Delta Fountains said the company has done architectural and floating fountain designs for universities, police memorials, parks and more. They are also the firm behind the Oklahoma City memorial reflecting pool, built in honor of the lives lost on April 19, 1995 and the memorial at the Pentagon. Delta collaborated on the project with Siemens for the automation, pump and flow controls. Dan Euser of Waterarchitecture also worked on the project as well

Challenges in Engineering

There were more than a few challenging engineering feats Delta had to achieve in order to build the pools for the 9/11 memorial site. The weir structure they devised had specific requirements, one was the ability to easily adjust and level water flow to within 1/16th inch over 1400 linear feet.

The 9/11 Memorial took ten years of planning and building before it was completed in 2011.

Another challenge for Delta was avoiding dry spots. Engineers accomplished this thanks to integral-design adjustability which allows for constant expansion and contraction of adhesive materials while still maintaining structural integrity. They devised a method of adding ribs which helped to prevent buckling and allowed field welding.

How the reflecting pools are controlled and maintained

By far one of the most impressive aspects to these two reflective pools is the sophisticated smart chemical filtration system they use. The system is able to anticipate and react to New York’s inclimate weather conditions on the fly.

Chief Engineer – Anthony LoCasto, says it takes a crew of three men to clean the pools 5 nights a week and roughly 8 hours to clean, vaccuum and brush each of the memorial pools.

Both of the pools utilize a total of 16 pumps to circulate 26,000 gallons of water each minute. The system is responsible for circulating over 480,000 gallons of recycled water.

There is also a cutting-edge networked control management system which effectively monitors over a thousand different data points about the pools to maintenance personnel, making it one of the smartest pools on the planet.

The maintenance crews perform goes far beyond simply maintaining the pools; displaying a reverence for the victims with gestures of remembrance. One of their duties is placing a white rose on top of each victim’s name who has a birthday each day before the memorial opens to the general public.

The project, which also includes an underground museum that utilizes parts of the fallen towers, had a budget of $610 million and offically opened to the public on September 12, 2011; ten years and one day after the September 11th attacks.

Natural Pools – The Pros & Cons of Going Au Naturel

We look at the Pros and Cons of Natural Pools and discuss the chemistry & science behind NSP’s. With guests Rudy Stankowitz & Allen Schnaak.

Natural Pools - The Pros & Cons of Going Au Naturel - Are NSP's (Natural Swimming Pools Safe?)

The chlorine shortages we’ve been facing this pool season has consumers looking for viable alternatives to a traditionally chlorine sanitized pool. Natural pools first started as a trend a few decades ago in Europe and over the past few years have slowly been gaining traction in the United States and Australia.

A Natural Pool BioNova built in Germany.

What is a Natural Pool?

A natural swimming pool typically doesn’t use chlorine for sanitization. NSP’s use plants to filter the water chemistry naturally, without chemicals. In most applications, the swimming pool is divided into two different sections: an area for swimming, and a dedicated regeneration zone with living plants that feed hydroponically on the water.

How does a natural pool work?

The water itself is naturally filtered by microorganisms through biological filtration plant life in the regeneration zone. The water is cleaned and filtered as it passes through the regeneration zone, and then back into the swimming area. A pump allows slow moving water to passively filtrate and the movement helps prevent mosquitos from breeding.

Small aquatic animals, such as microscopic algae-eating daphnia, snails, and amphibians, will typically colonize the regeneration zone of a natural pool environment over time.

This photo of a natural pool appears to have the blue water U.S. consumers expect in a chlorine pool.

Natural Pools Are Becoming More Popular

Allen Schnaak, Vice President of Business Development for BioNova Natural Pools thinks this could actually be a pivotal moment to introduce the pool industry to a new way of looking at how to filtrate and treat bodies of water. Recently Schnaak spoke with the Wall Street Journal touting the virtues of a chemically independent pool environment, and suddenly folks have begun to seriously pay attention.

BioNova is one of a handful of companies around the United States that are specializing in building NSP’s (natural swimming pools). Schnaak, who has appeared in numerous articles on the subject, has been working to educate consumers as well as the pool industry about the benefits of bio filtering swimming pools without the use of chlorine or other chemicals.

The Value Proposition of owning a Natural Pool

“Biological filtration in a natural pool has the same objectives as chemical applications.” said Schnaak who has a long history in the pool industry and worked on the chemical side before embracing natural pools. “The purpose of adding chemicals to the pool,” continued Schnaak, “is the same purpose of biological filtration and that is to reduce and suppress the opportunity for pathogens to exist and thrive in the water.”

“We’re seeing this play out in natures backyard in Tampa Bay right now with the red tide influenced by a greater amount of nutrients than the ecosystem can consume which gives these pathogens an opportunity to thrive.” said Schnaak referring to a toxic algae bloom which has ravaged marine life and killed millions of fish over 100 square miles of Florida coastline.

We’ve seen plenty of articles discussing natural pools, how they work, and why consumers should consider building one. In my discussions with Schnaak prior to our interview, I asked him if he would be willing to have a frank and open conversation with Rudy Stankowitz who has openly expressed his disdain for natural filtration and disaffectionately refers to NSP’s as “ponds”. Schnaak jumped at the opportunity to address Stankowitz one on one on the Pool Magazine podcast.

The timing for Schnaak to pitch the value proposition for natural pools couldn’t come at a better moment. With the current shortages consumers are facing, plus a new emphasis on eco-consciousness, the opportunity is there for bio pools to pick up enormous traction. The problem however, is winning over the pool industry. Folks like Rudy Stankowitz, one of the foremost experts in swimming pool algae have their own ideas about how viable bio filtration truly is in comparison to using chlorine.

Advantages of Natural Pools

  • Natural pools are eco-friendly and can work in a range of different climates.
  • Natural pools do not rely on chemicals like chlorine to sanitize the water in the pool.

Disadvantages of Natural Pools

  • Require larger lot sizes to build essentially two pools, one for swimming and the other to function as a regeneration zone.
  • Water color and clarity is not identical to that of a chemically treated chlorine pool.

“It is not necessary to chemically treat a pool in order to make it viable and healthful for someone to swim in.” said Schnaak, “Our opportunity in the market has certainly increased, and we’re definitely anxious and interested in getting more of our pool industry cohorts to consider that there is a viable option outside of chemical treatment.”

An Opportunity To Convince Non-Believers

Stankowitz, who recently authored a new book “How To Get Rid of Swimming Pool Algae“, has appeared on the Pool Magazine podcast when we discussed the chlorine shortages and the trajectory this years supply chain would take. Extremely knowledgeable when it comes to swimming pool chemistry, Stankowitz is a 30 year veteran and CEO of Aquatic Facility Training / CPOClass.com.

Allen Schnaak and Rudy Stankowitz went head to head in a thought prevoking discussion about the pros and cons of natural pools.

We felt that having Schnaak and Stankowitz go head to head would make for a compelling dialogue and we weren’t wrong. Stankowitz’s expertise and viewpoint create the perfect counterpoint for a dynamic conversation about natural pools. Schnaak and Stankowitz go way back and have a mutual respect for eachother, but currently they sit on opposite sides of an important issue. Whether natural pools are as safe to swim in and ultimately as cost feasible as chemically treated pools.

Are natural pools as cost efficient to build and ultimately maintain as traditional chlorine inground pools?

“Really, I’m not a fan” said Stankowitz, “I am a fan of algae being used for other things. Things are progressing, there’s been a lot more fuels. Even in waste water treatment, algae has become a major player. My problem is that this is basically a pond and it looks like a pond.”

“As long as anything living gets into it, there is going to be constantly things that are introduced to that body of water that are not able to be eradicated quick enough that it can’t cause a potential problem for human beings. The follow up to that which is just as heavy is water clarity. We know that 10% of all drownings are attributed to cloudy water situations.” said Stankowitz.

Schnaak says that people need to rethink the notion that natural pools are green messy bodies of bond water.

“The preconceived notion that all natural pools are green messy bodies of pond water are just a misimpression. We’ve done pools with water clarity easily down to 12 feet. I’m a big believer in safe water environments. In fact the swimming pools we design are built to ICC and ANSI standards. The vessels are safe, and to that point water clarity is not an issue.” said Schnaak.

“If your only experience with a natural pool is looking at a green cloudy pond, then there’s a greater exploration of opportunity. We’ve got a 20,000 square foot public pool up at Webber Park with a 13 foot diving well that is totally clean with a 500 person bather load.”

  • Swimming pool is 21,000 sq. ft. (500,000 gallons water)
  • Regeneration basin is approximately 16,250 sq. ft.


“The Opportunity Is On You”

Stankowitz replied “We’re giving you the benefit of the doubt. The opportunity is on you…” in reference to changing perception in the market that not all natural pools are ponds. “I’ve only seen the pictures that people put out there and honestly I have never in any magazine, in any post or anywhere seen a natural pool that is not green. So the opportunity for education is on you. I’ve known you a long time and I believe you.”

Natural Pools utilize a regeneration zone to biofiltrate water back into the pool.

“From the standpoint of the industry and where it is in the United States, natural pools are not nearly as prevalent in the U.S. as they are in Europe. 16% of the recreational water in Europe are natural swimming pools. Probably less than 0.3% in the U.S. can be termed as a natural pool.” said Schnaak.

“The opportunity for helping the industry recognize that this is a viable method for maintaining recreational water is on us, you’re right; and it’s really up to the market as well. There certainly is an increasing interest by those looking for more sustainable options for pool care.” continued Schnaak.

“The opportunity for nutrients to be put into a body of water is going to be defined by the footprint that it has in the landscape.” said Schnaak. “As any pool is constructed it’s always built so that it does not allow surface runoff to enter the pool.”

Debating The Safety of Natural Pools

“We do know that with a given square footage there is an anticipdated amount of environmental depositions of nutrients that are constantly bombarding the pool.” said Schnaak, “In a chemical environment they are referred to as contaminants because everything that can be oxidized, reduced or killed has to be killed as soon as you begin taking out the beneficial microbial life that would be consuming it.”

“I don’t necessarily know that I agree with you that if you have diatoms present in a body of water that you will not see cyanobacterial biofilm.” said Stankowitz.

“I understand the process that we’re feeding the water with phosphates and silicates so that diatoms can outgrow and use up the nitrates so that nothing else can have them therefore they don’t grow. In theory, that works great. The problem is just like there are carbon fixing diatoms, there are nitrogen fixing cyanobacteria so you will still have these biofilms, and these biofilms do harbor many other disease causing organisms such as Legionella and Naegleria fowleri (the brain eating amoeba),” continued Stankowitz.

“I’ve done extensive studies on black algae which is cyanobacteria and in those biofilms I’ve found diatoms living happily. It’s not an incompatible relationship if you have the right diatoms and the right cyanobacteria.” said Stankowitz.

“It’s interesting that diatoms are a participant,” responded Schnaak, “they are part of the population, but they are not the only microbial life. When you consider phytoplankton, zooplankton, the entirety of population of beneficial bacteria that has been specialized for the nitrogen reduction cycle.”

Schnaak suggested that copepod zooplankton like Daphnia which grazes in fresh water environments on cysts like Cryptosporidium and Giardia and harmful viruses to which Stankowitz responded with a few different “what if” scenarios. “To your point about Daphnia, it feeds til it explodes and releases that back into the water. That’s also the problem we are having with the red tide. Daphnia doesn’t last long enough to contain it all and then if it’s consumed by an animal, a person can eat that animal, or it can be defecated or released into the atmosphere and that could make it’s way back into the pool.”

Changing Perception That Chlorine Is King

“I think the major challenge for you,” Stankowitz said to Schnaak, “is chlorine does kill these things. We have proof that chlorine kills those things. What we need then if this is true, if this system takes all these things out, we need to get that research out and make that common knowledge because that’s how you gain more acceptance in the pool industry,” continued Stankowitz.

Schnaak agreed and said that as a member of the council for the Model Aquatic Health Code that they’d begun participating in an ad-hoc committee for the evaluation and potential implementation of biological filtration for public aquatic venues. Schnaak agreed there is much that is still misunderstood about natural pools and that each project has to account for the specific environment, size, bather load and unique characteristics.

No One Size Fits All Solution

Natural swimming pools are very dependent on maintaining ideal conditions for the plant life which bio filtrates and allows useful organisms to thrive. “There isn’t a one size fit’s all, neither is there in chemical applications. There’s not a pool out there where you couldn’t find a pathogen or organism living in that environment. The presence of chlorine does not indicate a sanitized environment.” said Schnaak.

Ultimately, Stankowitz still had serious questions pertaining to how long harmful pathogens can survive in the biofilm in a natural pool and insists that chlorine is still the most reliable solution for sanitizing pools. Schnaak is adamant that the system that BioNova has created is capable of biologically filtering swimming pools to the point where they are viably safe swimming environments.

Stankowitz said that while he’s open minded to the concept of natural pools, he needs to see more conclusive research on the subject before he’s swayed from using tried and true chlorine sanitization methods, which prompted Schnaak to invite him and as well as others interested in learning more about natural filtration methods, to seek out more information on the Association for Swimming Ponds and Natural Swimming Pools website.

Natural pools and ponds have become increasingly popular with the recent chlorine shortages

Why Have Natural Pools Been Slow To Catch On In The U.S.?

While natural pools are becoming increasingly popular in Europe, there is no denying that they have a nominal marketshare in the United States. In this humble editors opinion, there are several impediments towards more acceptance beyond those early adapters.

One is the public perception that all pools must have crystal clear blue water. Another are the requirements for constructing a natural pool. Given the need for an additional regeneration zone, most natural pools are typically built on larger sized lots. The initial build and configuration cost for a natural pool is also much more than your typical inground pool. There is definitely some give and take in terms of initial cost concerns versus ongoing chemical costs.

There are also a good portion of consumers that while aware of natural pools, have a tendency to believe a popular misconception; which is that NSP’s maintain themselves. Natural pools, just like chemically treated pools still require routine maintenance and to some extent even more attention than a chemically treated pool in order to ensure a harmonious water environment.

Still Schnaak remains a champion for the bio filtration cause and says a growing percentage of environmentally conscious homeowners yearn to go chlorine free. As such, he will continue to facilitate and fan that interest to generate more excitement and awareness about natural pools.

Hurricane Ida Slams Louisiana, Pool Industry Waits to Assess Damage

Pool Industry Report – Hurricane Ida has utterly ravaged parts of Louisiana and may be responsible for millions in damage.

Hurricane Ida has utterly ravaged Louisiana and may be responsible in potentially millions in damage to pools

The entire Gulf Coast region is reeling after Hurricane Ida made landfall in Louisiana, knocking out power to virtually the entire state. The category 4 hurricane obliterated roofs and actually reversed the flow of the Mississippi river as it pounded the region, causing a swath of devastation to whatever was in its path.

So far the Hurricane has been responsible for at least one reported death and has disrupted most services to a good portion of Louisiana. The pool industry still vividly recalls the effects of Hurricane Katrina which caused $81 billion dollars in property damage back in 2005 and impacted about 90,000 square miles of the Gulf Coast region. That particular storm was a Category 5 Hurricane and was responsible for over 1,800 deaths.

Hurricane Ida may be responsible for potentially millions of dollars in damage to ongoing pool construction projects.
Hurricane Ida may be responsible for potentially millions of dollars in damage to ongoing pool construction projects.

Pool builders got wind Hurricane Ida was coming, but scarcely had time to prepare job sites. At this point, given the level of damage the storm caused to the local area, many pool companies are looking at potentially millions of dollars in damage to vessels currently under construction.

Weather conditons such as hurricanes and tornadoes are capable of flattening a home within seconds. In many instances, the sheer force of the storm can destroy swimming pools. One storm in Australia a few years ago completely ripped a pool from the property and shows the power that severe coastal storms have and the damage they can inflict.

We all have seen first hand what ravaging hurricane winds can do to vessels. When confronted with storms of this magnitude, there is no guarantee that even the best built structures can withstand winds that exceed over 150 mph.

Jefferson Parish Emergency Management Director Joe Valiente gave his assessment of the current situation and said that local area residents may be without power for 6 weeks or more. “There are about 10 parishes that the electrical grids are completely collapsed and damaged, smashed, out — however you want to put it,” said Valiente.

The storm caused a main electricity tower to collapse into the Mississippi River, severing a critical link between power stations and five parishes. Although much of the region is currently flooded, Valiente said the one piece of good news was that the region’s levee system held up well, with only minor issues.

One of the most powerful storms to hit the area in recent years has left many communities isolated. Virtually no one in the state has electricity and many water systems are also out, Governor John Bel Edwards told media. Many local parishes throughout the New Orleans area are still flooded. President Biden declared a state of major disaster in Louisiana, coordinating 3,600 FEMA personnel to begin distributing aid immediately.

It’s difficult to gauge the exact impact on the pool industry at this point. Attempts to reach out to many local area pool builders met with failure. Many of the phone lines are down and millions currently remain without electricity. Emergency 911 services are also still down for many portions of the region.

A winter storm hit the pool industry hard last year and caused a deep freeze the contributed to supply shortages hindering builders and service techs this season.

A 100 year storm of this nature is one that few are ever prepared for. Louisiana has already been desperately trying to cope with overwhelmed hospitals that are dealing with the Covid-19 pandemic. Local area residents are struggling with what little resources remain and can use whatever help they can get.

How Can The Pool Industry Help?

Mule Men, a charitable foundation that distributes humanitarian aid and is organized by such pool industry figures such as Shane Le Blanc, Jimmy Smith and others is already organizing relief efforts to distribute goods. Making a donation there is a great way to make an impact if you want to make a difference.
