Celebrating 45 Years of Keeping Business Flowing!

DEWCO 45th Anniversary

DEWCO is 45-years-old this year.  We’ve been serving the fluid control needs of the Rocky Mountain Region since– gasp– 1974!  Where did the time go, right?  Just to give you some perspective, back in ‘74 gas was about 53 cents a gallon, a new car cost $3,500, and a new house was $47,432.  Prices have, as expected, gone up since then, but one thing’s the same: our company is still mission-driven and all about quality customer service.

Our mission continues to be, “Providing solution-driven products and service to our customers while maintaining a responsible, innovative, community-oriented environment for our team members.”

Through the years, DEWCO has served tens-of-thousands of customers.  We have – and continue to – supported many different markets and industries.  Here are just to give you an idea:  mining, power, oil, gas, water/wastewater treatment, HVAC, agriculture, biotech and food/beverage.  Heck, we’re even involved in brewing, distilleries and wineries!

Along the way, our company has interacted with so many different people, from OEMS to operators, manufacturers to municipalities, sub-distributors to resellers.  All the while, integrity has been the cornerstone on which DEWCO was built and still operates. We’ve always wanted to help make others successful, and that, in turn, has helped make us successful for of these decades.

As a family owned-and-operated business, DEWCO certainly appreciates its customers in places like Montana, Utah, Wyoming, Colorado, New Mexico and beyond. We have enjoyed being the largest and best distributor of fluid industry products. Based in Lakewood, Colorado, our geographic reach is expansive. We love the Rocky Mountain Region and we’re glad we’ve had the opportunity to meet the needs of so many people and businesses here.

DEWCO looks forward to being the supplier for engineers, contractors, maintenance teams and others, with liquid flow meters, storage/containment tanks, pumps, valves, tubing, instrumentation, cooling tower controls, boiler treatment supplies and hundreds of other items we have in stock for the next 45 years and beyond. We offer the best brands in the business, including Peabody, Seametrics and Pulsafeeder.

As part of our 45th Anniversary, we’re celebrating at our Lakewood office with an open house and free BBQ luncheon. All DEWCO customers, friends and family are invited to join us on Thursday, August 8 (11am-2pm). We will have games, prizes and more! Please call our office at 303.232.6861 or email sales@dewco.com to RSVP – we would love to have you join us!

DEWCO Engineers Design Wastewater Neutralization System

Wastewater Neutralizaion System

When Upslope Brewing Company in Boulder, CO was recently tasked with finding a cost-effective solution for their wastewater challenges, they called DEWCO – and with their solution, DEWCO may have revolutionized the brewing industry.

Early in 2018, City of Boulder officials informed Upslope, and all breweries within the city limits, that monitoring of wastewater discharge would soon begin.  Prior to 2018, no standards had been established for these businesses on their wastewater discharge.  This was big news, and a big issue, for many of the micro-to-small sized breweries in the area.

As part of their brewing process, most brewers engage in a CIP (clean-in-place) tank cleaning process.  This process was resulting in high concentrations of acid and caustic (corrosive, destructive) fluids circulating through the brewery tanks and other equipment, down their drains and ultimately into the city’s sewer system.  This had been happening for years, in some cases decades, resulting in issues with the city’s sewage piping, infrastructure and treatment systems.

Enter heightened compliance mandates from Federal and Municipal officials.  New lawsDewco Pumps were quickly enacted that regulated the pH (measurement of acidity and other harmful chemical levels in the wastewater) that breweries are permitted to discharge.  The allowable level was established in a range of 6-to-10.  Dramatically lower than early testing results.  Now, if brewers don’t meet and maintain the criteria, fines could be assessed for discharges outside the allowable range.

Often, micro/small breweries don’t have the budget or physical space for a large wastewater operation.  In Upslope Brewery’s case, numerous mechanical and engineering issues made it a difficult and expensive problem.  However, after several brainstorming sessions and countless hours of engineering and design, Sean Doyle with DEWCO was able to crack the code.  “We found an economical and reliable solution in the treatment system designed by Sean Doyle at DEWCO” said Ryan Smith, Brewery Engineer/Facilities Manager at Upslope.  “Working with Sean made a compliance solution easy.”

Through Doyle’s design, DEWCO was able to deliver a cost-effective collection, neutralization system for Upslope’s wastewater.  A prototype of sorts, the DEWCO Waste Management System (WMS) collects the fluids from several caustic and acid rinse cycles in a collection tank.  Many times, the solution, once collected, is already close to being within the mandated pH specifications.  With the use of two pH probes, one in the tank for neutralization and one in the discharge line for monitoring, as well as a color, touch-screen PLC controller, Smith can customize the system to Upslope’s specific needs.  The system also features a recirculation pump for mixing, two chemical pumps (one for acid and one for caustic), a tank (matched in size for the brewery’s needs) and discharge valve.

When the fluid level in the tank reaches a predetermined point (adjustable and controlled by the brewery), the recirculation pump will begin cycling the solution.  Depending on the current pH level and discharge settings, the chemical pumps will begin dispensing to the tank.  Once the pH levels in the tank fluid reach the desired limits, and held for a specified time, the discharge valve opens and the (now) neutralized solution is safe to drain into the city’s sewer system.  For insurance purposes, in the final drain line, another pH probe and valve have been installed to monitor the outgoing fluids.  In the event the pH level should ever fall out of the specified range, dischargDewco Pumpse can be stopped until the issue is addressed.  The result is both brewery and city are assured that no unacceptable solution is reaching the sewer.

Upslope is among the first breweries to embrace the change in compliance.  And additional benefits have been realized through the process, a reward of sorts.  “We’ve also seen a big reduction in process chemical use and other expenses” Smith noted.  “I can’t speak highly enough about our experience with Sean Doyle and DEWCO.”

“This was a challenging, yet very rewarding project to be involved with,” added Doyle.  “Ryan and his team were great to worth with and I’m proud that our system not only solved their compliance issues but was able to make Upslope more efficient by saving them time and money as well.”

With this revolutionary system design, and with dozens of breweries in Colorado alone, DEWCO could be in line for busier times ahead.  Which is music to the ears of Dale Olinger, DEWCO’s president.  “I could not be prouder of Sean and his collaboration with Upslope!  His efforts, once again, demonstrate DEWCO’s commitment to environmental stewardship through cost effective and sensible solutions.”

We’d like to take this time to further educate you on the COOL-FIT System to help you make a confident and informed decision when you consider upgrading your cooling systems.

What is COOL-FIT ABS Plus?

When it comes to cooling systems for breweries, supermarkets, food processing, and other businesses that rely on cold products, they can spare no expense. Having a system failure could be catastrophic to these industries so reliability is paramount. However, if a company spends all their profit on a high-end cooling system, they could regret that decision in time as well which makes the COOL-FIT ABS Plus is an ideal solution. It is dependable, cost-friendly, environmentally friendly, and so much more.Highlighting the COOL-FIT ABS Plus

Essentially, the product is a ready-to-install pre-insulated plastic piping system perfect for both refrigeration and secondary cooling systems. We figure, it if isn’t broken then don’t fix it, and that is why this system is based off the ABS plastic system that was created way back in 1986. You also get the luxury of choosing from black or white outer jackets. The black is UV resistant, making it ideal for outdoor applications while the white is considered perfect for clean environments including food processing plants.

The pipe is a 150 psi rated, cement jointed ABS plastic pipe with a thermal conductivity of 0.026 W/m.K, an expansion coefficient client 0.04 mm/m.K, and a core density of greater than 2.8ft. All of this adds up to a well-made and dependable product.

You might be wondering how COOL-FIT measures up to the competition. The great thing is that there are so many benefits that to choose anything else would be counter-productive. Here are a few of the most important benefits that this product provides.

Easy to Maintain

When you invest in a quality product, the lack of necessary maintenance makes it all worthwhile. This system is manufactured using high-grade pressure-rated ABS, which is totally corrosion free, both externally and internally. That means you won’t have to worry about when you might have to replace the system. We are so confident in it that we predict the product will last for 25 years.

Maximizing Efficiency

Most businesses want to optimize their efficiency at every turn and with COOL-FIT ABS Plus, you can depend on receiving a high-impact product. Many companies are still using traditionally insulated systems that are infamous for absorbing water from the atmosphere which in turn negatively impacts the insulation ability while also leading to cracking, ice build-up, and more.

The COOL-FIT is buiDEWCO Cool-Fit ABS Pluslt to purposely avoid these issues by being water and vapor tight. Plus, the smoothness of the plastic pipes works to prohibit fluid build-up resulting in reduced pressure loss, thus creating that necessary efficiency that your business needs to remain competitive.

Low Weight

Many companies will avoid a product simply because it is difficult to handle and install. With COOL-FIT ABS, that issue is alleviated. This system is made of low-density plastic which, when paired with the simple, cost-effective hanging structure, creates a product that is easy to install and maintain. Plus, no welding or special joining equipment is required.


As mentioned earlier, a lot of products can promise the world, but another factor weighs heavily: the cost. When compared with other, similar products, COOL-FIT ABS has the competition beat. When compared with brands such as Electrofusion, the differences are clear. In many cases, integral pieces including elbows and couplings can be bought for less than a quarter of the price of the other guys. All this means is that not only are you getting a better product but you also protecting your bottom line in the process.

Dual Containment Tanks: Keeping Your Storage Safe

Do you own or operate a business or company that relies on storage tanks for chemicals, additives or other materials that are integral to your operation? If so, you’re probably also aware of the importance of having an emergency containment plan in place in case of an accident or spill. Fortunately, there’s a simple solution available: Dual containment tanks.

Dual containment tanks are an excellent choice for those who want to store chemicals as safely as possible and reduce the risks associated with spills. Let’s explore some of the benefits and features of dual containment tanks and how they might be the perfect solution for your business.

Dual Containment TanksWhat Are Dual Containment Tanks?

Dual containment tanks are uniquely constructed tanks that feature both an inner tank and an outer tank shell that serves as an integrated catch in case the internal tank breaches. This is a very important feature for those who use tanks to store chemicals, because as you probably know, spills are one of the biggest problems associated with storing them.

When you install dual containment tanks as opposed to standard types of tanks, the built-in secondary spill containment provides a built-in safety net to prevent serious spills and hazards. Dual containment tanks are also commonly referred to as dual wall tanks, double wall tanks or secondary containment tanks, and they are extremely effective and popular for storing caustic chemicals and reactants in a wide range of businesses and industries.

What Are They Made Out Of?

The majority of the dual containment tanks that we sell are created using high-density linear polyethylene. This material is ideal for products that are designed to provide secondary containment. This provides a nonreactive shell for a majority of the most commonly used industrial chemicals and other fluids such as sulfuric acid, sodium hypochlorite and other inorganic acids and bases used in production, water treatment or any other application.

Who Could Benefit From Using Them?

Any companies that currently use storage tanks to house chemicals should consider using dual containment tanks. Those companies that use chemical feed systems or utilize water treatment chemicals have found these types of tanks particularly useful. They are available in a wide range of sizes, including tanks capable of holding just five gallons of chemicals all the way up through tanks with a capacity of 500 gallons. These tanks are often filled with chemicals that are vital to the operations of a variety of businesses, but that could potentially cause big problems if they were to ever spill. With a dual containment tank, however, any spills or failures of the internal tank would be contained by the secondary tank wall, providing essential safety and security.

Square Containment TanksWhat Brands Does DEWCO Carry?

DEWCO has stocked dual containment tanks in stock for several years now, but we have recently made a strong push to add the latest tanks to our inventory. Gemini Dual Containment Tanks and Gemini2 Dual Containment Tanks, which offer a unique square shape, are two of our most popular options. We also carry ProChem dual containment tanks as well as tanks offered by several other reputable companies.

All of the dual containment tanks that we provide for our customers are designed to meet or exceed EPA codes as well as fire codes, and they can often times be integrated directly into whatever systems you currently have operating inside of your facility. DEWCO carries a large selection of these types of tanks and is currently in the process of expanding our inventory to add even more options to meet the diverse needs of our customers. This allows us to offer the best possible options and prices to our customers while also reducing the time between order placement and delivery.

DEWCO has been in business for more than 40 years now, and we have worked with an extensive range of clients in different industries. From oil and gas companies to water treatment, HVAC and manufacturing services, we have set many companies up with the perfect storage tanks for their specific needs. When you call on us for our dual containment tanks, we promise to walk you through the benefits of them and tell you all about how they could help keep your storage safe when you use them.

Monitoring Water Use for Fracking Operations

Hydraulic Fracturing

The oil and gas industry is finally showing signs of recovery following the long downturn that saw oil prices drop from more than $100 per barrel to less than $40. While there is still a lot of room for improvement, a growing number of analysts and industry experts are optimistic about industry growth in the coming months and years.

Hydraulic FracturingFracking has emerged as an important part of domestic energy production in recent years, and is now the primary stimulation technique used in unconventional oil and gas reservoirs, according to U.S. Geological Survey. In 2000, by comparison, only about 6 percent of hydraulically fractured wells used water-intensive horizontal drilling, but that number had risen to 42 percent by 2010. As production in conventional fields continues to decline, fracking will likely play an ever-more-important role in meeting domestic energy needs.

Water is an essential part of the fracking process, with most wells requiring millions of gallons, depending on the type of rock and whether the well is horizontal or vertical. According to the USGS, typical usage varies from about 1.5 million gallons per well in the North Dakota Bakken Formation up to about 15.8 million gallons per well in the British Columbia Horn River Shale.

Considering the importance of water – and the volume that is required for fracking – it is essential that drilling companies and water suppliers are able to accurately track water usage and flow. As is the case with many things in business, what is not measured cannot be managed. Considering the large volume of water that is required for fracking, even modest gains in efficiency can pay large dividends.

Energy producers are under increasing pressure to limit the potential environmental impact of fracking. This pressure comes from a variety of sources, including government regulations, environmental activism, agricultural producers who are competing for limited water resources, and the rising cost of materials used in fracking. Sand, which is another important material for hydraulic fracturing, has risen in cost considerably during recent years, notes Rock Products. The cost of water for use in fracking is also rising.

Water costs now account for about 14 percent of the overall expense for new wells in the continental U.S., says Verisk Maplecroft. According to some reports, the cost of fracking water has doubled in recent years. In the next decade, the development of new wells in water-stressed regions is expected to double, which will increase water costs further. The cost of water is further exacerbated by the lack of infrastructure in many areas, resulting in water being imported and exported by truck.

Given the importance of water for fracking, the rapidly rising costs of water, and the probable shortages in the future as new wells are developed in water-stressed areas, monitoring water flow and usage will become increasingly important. Fortunately, new technologies are being brought to market that will allow drilling companies and water suppliers to monitor water with more accuracy that has been possible in the past.

TelefloThe DEWCO Teleflo is a cellular based, real-time monitoring and data logging solution. With the DEWCO Teleflo, drilling companies and water suppliers now have accurate, real-time flow rates and totals at their fingertips, with password level protections built in. Water supply businesses are particularly affected by the tightening supply and rising costs of fracking water, and having tools available like the Teleflo system can lead to improved monitoring of water flow and volume, allowing drilling companies and water suppliers to monitor levels and make important make business decisions in real time – as needed, when needed.

DEWCO has been meeting the fluid control needs of businesses throughout Colorado and the Rocky Mountain region for more than four decades. We partner with trusted manufacturers to supply the best products to our customers in the oil and gas industry, as well as many other fields, and we are excited to bring new remote water monitoring solutions to oil and gas industry businesses. Contact us at 303 232-6861 to learn how we can help with remote water monitoring or other fluid control solutions.

Water Management: Controlling, Measuring, Maintaining and More

Industrial Water Treatment

According to National Geographic, even though water covers 70 percent of the Earth, only 2.5 percent of that water is fresh, and only 1 percent of the fresh water is readily accessible.

Meanwhile, the news is filled with threats of water shortages and pollution challenges. All of this brings significant concerns to how we are managing our water.

Effective industrial water management is crucial both in standard everyday applications such as car washes and water cooling, but also in more complex operations such as fracking and even construction projects that can impact local freshwater sources. Here is a brief overview of how companies like yours can more effectively measure, monitor and control this precious resource.

Industrial Water TreatmentManaging Industrial Water

An important part of industrial water management is accurately controlling the water flow during use. Controlling the flow is essential because having a consistent flow of water allows treatment protocols to remain consistent so that wastewater can be efficiently and effectively managed.

Several methods of flow management are available to help with controlling the water. Valves can be set to allow only specified amounts of water through at a time. When using valves, the flow must be recorded on a regular basis to verify consistency and flow volume. The use of a suitable valve is paramount in accurate water flow control.

Maintaining Industrial Water

Industrial water treatment is essential in managing the issues that can occur when utilizing large amounts of water, with the major factors including scaling, microbiological activity, corrosion and residual wastewater byproducts. It is important to manage these issues and isolate them from source waters so that the local waters are not compromised.

Scaling, sometimes known as precipitation fouling, occurs when the temperature and similar factors cause the minuscule dissolved mineral salts which are already in the water to precipitate and then form solid deposits. These deposits can build up in layers on the metal surfaces of these systems and lead to obstructions in piping and reduced flow rates.

Scaling in Water Treatment PipeThe real issue with scaling is that as the scale thickens, energy is wasted due to the heat exchangers becoming less efficient. For industrial projects, this can mean time and money wasted because increased energy is needed to pump water through tighter pipes.

To resolve this issue, you can employ polyphosphates or similar tools that coat the iron and make it difficult for these minerals to build up.

Similar to scaling, corrosion occurs when metal oxidizes and compromises the water treatment equipment. There are several ways to control corrosion, including employing orthophosphates, polyphosphates and blends of each.

It is essential to manage and eliminate any microbes that may thrive within the untreated water, as well. Many diseases have been traced back to unmanaged cooling towers, most infamously including Legionnaires’ disease. These issues must be resolved by some form of biocide before the problem becomes toxic.  Ultraviolet (UV) systems can also provide effective control of biologics.

Residual wastewaters can also be a problem addressed by water treatment. The disposal of these wastewaters from industrial plants, for example, can become a very costly problem and national guidelines have been put in place to avoid having these tainted waters enter the public water supply.

Measuring Water for Use and Treatment

It is as true with water as it is with anything – you can’t manage what you don’t measure. Proper measuring of industrial water is one of the basics of using water as efficiently as possible during these times of water scarcity. A primary solution to the issue is the use of flow meters and transmitters.

Flow meters are having a significant impact on water measurement because they improve data analytics by showing how much water is being pumped into the system and how much water is reaching customers or project sites.

When it comes to water delivery, it is essential to measure non-revenue water or water that is lost before it reaches the customer. These modern meters monitor the flow of that water with incredible accuracy, meaning that companies can keep a close track of what is being used and even use measurement to identify potential leaks or damaged piping from meter to meter.

Cities, for example, often draw their water from many different sources and require a complex system of pumping stations, meaning that the cycles of these networks must be optimized. Flow meters can test the pumps to measure efficiency then compare it to operating specifications, helping guarantee a consistent flow of water throughout a city-scale network.

In the end, the flow meter and similar data logging capabilities are becoming some of the most valuable tools in proper water management as they maximize and streamline revenue generation, cost control, and of course, conservation of this precious resource.

HydrofrackingWater Management and Fracking

Now that fracking has emerged as the massive enterprise that it is, concerns for proper water management are starting to grow in an attempt to lower the risk of negatively impacting the local water table while also fighting rising water costs.

The act of hydrofracking involves drilling deep into the earth and releasing a high-pressure water mixture at rocks below in an attempt to release the fluids inside.

As an industry, fracking consumes more than 1 billion barrels of water on an annual basis and creates half that amount as barrels of wastewater for disposal or treatment, reports Water Online. This is enough to fill 150,000 Olympic-sized swimming pools. Managing all this is no minor task, as Investopedia notes, and the industry will end up paying north of $6 billion in wastewater management.

Many states have made their concerns known regarding the surpluses of wastewater and corporations are being tasked with reporting how much water was used and/or dumped on a monthly and yearly basis.

Fracking companies must also take precautions as the procedure can potentially cause the release of tainted fracking water or the natural gases into the groundwater, polluting the local water table in the area around the fracking site.

Fracking has the potential to be a great source of gas and oil reserves, but proper water management during the operation is vital to ensuring the long-term viability not only of the procedure, but the local residents and animals that rely on the region’s water.

At DEWCO Pumps, we are a leader in industrial water management technologies, and our suite of high-tech equipment and devices offers companies all the tools necessary to effectively manage, measure and treat their water and wastewater. Our inventory covers measurement tools, flow instrumentation, various valve options and containment tanks. We are water management experts, and we are happy to answer any of your questions.

Cooling Towers and Preventing Legionnaire’s Disease

Ray Brennan probably looked forward to his three-day American Legion convention in Philadelphia back in the summer of ’76 – old friends, war stories, great food and maybe a little business. He probably did have a great time, which explained away the exhaustion he felt when he returned home.

But three days later, he was dead.

Legionnaires DiseaseThe convention, held at the Bellevue-Stratford Hotel in downtown Philly, kicked off July 21, 1976, according to archived coverage from the Los Angeles Times. Brennan had plenty of company there: more than 2,000 American Legion members – primarily men – converged on the hotel for three days of Legion business. Conventioneers also took in Philadelphia’s historic sights, enjoyed the cuisine all over the city and spent time with each other, shaking hands, hugging and talking.

Another three days after returning from Philadelphia, the 61-year-old Brennan, a retired U.S. Air Force captain and a bookkeeper for the Legion, died at his home – July 27, 1976. The cause of death was ruled an apparent heart attack.

Three more days passed, and suddenly, four more Legionnaires were dead, also seemingly of heart attacks. The following day, the death toll mounted to 11, with all the victims suffering the same symptoms – fatigue, chest congestion, chest pain and a fever. Older adults, smokers and people with weakened immune systems were particularly susceptible.

Three of the dead men had been patients of physician Ernest Campbell in Bloomsberg, Pennsylvania, and the doctor knew all three had attended the convention just a few days before. Recognizing the dire implications of such an epidemic, Dr. Campbell contacted the Pennsylvania Department of Health.

Meanwhile, the people at the American Legion headquarters suddenly began receiving news of members’ deaths. Within a week, two dozen were dead and more than 100 were hospitalized. In total, 221 cases were reported with 34 resulting in death.

Back in that bicentennial year, most Americans hadn’t ever heard of the U.S. Centers for Disease Control and Prevention, but it soon became a household topic. The CDC launched an exhaustive investigation that lead them to rule out external culprits – a disease carrier, or something in common ingested, for example – and began to zero in on the hotel itself.

Legionella BacteriaOf course, you know the rest of the story. Months later, in January 1977, the lethal cause was identified as a bacterium the scientific community labeled Legionella. And, of course, you know where it was breeding: the cooling tower of the hotel’s air-conditioning system. From there, the bacteria then spread silently and invisibly throughout the air inside the hotel, settling in the lungs of visiting Legionnaires and blooming into a severe form of pneumonia.

“Five months after the convention, [CDC microbiologist Joseph McCade] took another look at some red sausage-shaped bacteria and concluded that they were the culprits,” Time magazine reported. “They had festered in the water of the hotel’s cooling tower and had been carried through the air as the water evaporated.”

If you’re old enough, perhaps you recall the immense relief that swept the country when the number of new cases dropped off – apparently, it wasn’t contagious. The discovery of the cause, however, spawned a whole new slate of fears because there were cooling towers in practically every building, just like the one at the Bellvue-Stratford. And it could happen again – to anyone. The fear was palpable: the public had a very loose notion of the science behind the disease and not much information on it.

Legionnaires’ disease began at least 33 years before the 1976 Philadelphia epidemic, and in the years since, it continues to claim victims.

Wikipedia offers a brief list of some of the most striking outbreaks in the past 30 years:

April 1985, England: 175 people in Stafford, England, were admitted to two local hospitals with a chest infection or pneumonia. More than two dozen did not survive. After the Legionella bacterium was found, an investigation pinpointed the source to the cooling tower on the roof of one of the hospitals.

March 1999, Holland: More than 300 people fell ill and more than 30 died of Legionnaires’ disease after attending a flower show.

July 2001, Spain: More than 800 suspected cases were recorded and six deaths reported.

September 2005, Canada: 127 nursing home residents fell ill, with 21 deaths that week. The disease was traced back to the air conditioning cooling tower.

November 2014, Portugal: More than 300 people were hospitalized and seven succumbed to the disease that festered in the cooling towers of a local fertilizer plant.

August 2015, New York City: More than 110 cases of Legionnaires’ disease and 12 related deaths were reported in the Bronx. The Department of Health determined that Legionella was found in the cooling systems of five public places, which were swiftly decontaminated.

August 2015, California: An outbreak of Legionnaires’ disease was detected at San Quentin State Prison in Northern California.

June 2015-January 2016, Michigan: Beleaguered Flint, Michigan, has suffered at least 87 cases of Legionnaires’ disease with 10 resulting in fatalities.

Water Cooling TowersThe original Philadelphia outbreak, of course, triggered new regulations for the climate control industry not just in this country, but across the globe. Preventing Legionnaires’ disease requires one thing: keeping Legionella from colonizing in your water system.

To understand that, let’s take a look at how a cooling tower works. It’s made to extract heat using water. Hot air intakes pass through the water, transferring heat from air to water and causing some evaporation, which rises and, when cooled, collects at the bottom of the tower and recycles for reuse, though there are restrictions for reuse in certain circumstances. Warm water is Legionella’s comfort zone, and cooling towers provide the perfect storm for this bacteria to multiply, infect silently and kill.

Proper cooling tower disinfection and maintenance practices are the key to preventing another outbreak and adding to the unfortunate death toll. Of course, a large part of that is having the proper equipment.
