CES Water Quality News Sharing Tips, Tech Support, New Trends, and technology updates !

New Daldorado White Paper Exposes the Risks and Solutions for improper deck grates.

CES has long been focused on providing water quality control (below the water line) for our customers, thankfully with great results. We also feel that it is our responsibility to alert customers if we see a potential issue “above the water line". Well, we recently found a great solution to a pretty common problem with perimeter grating, and are ready to help you identify and find solutions.


The New Daldorado White Paper is a detailed document that focuses on the underlying threats, codes and requirements, and potential solution - along with references and case studies. Please take a minute to read it as your facility might need a quick tune up to assure safety.


What grates are potentially dangerous? Deck drains, overflow and rim-flow grating injuries - mostly above the waterline can cause big issues. After all they have the HIGHEST LEVEL of patron interaction. While they don’t make headlines, issues are a lot more prevalent than you think and can expose your facility. The white paper contains several examples of accidents that aren’t really meant to scare anyone as much as to help point out the potential issues using real-life examples.


What are the potential issues? The white paper points out several: Slip and fall on non-compliant grates, injuries from collapsing grates that may or may not meet testing guidelines, and non-compliant gaps that are a major cause of finger and toe entrapment. Also the new IBC guidelines fine-tune the approved gap for grating, so it would be another good reason to fine-tune your grating to meet the new guidelines.

The slip and fall potential is a simple one to resolve as new CES grating has all been tested to meet the latest slip resistance guidelines. Resolving the collapsing grate issue is also fairly easy to do as new grating has been designed out of materials that are resistant to both sun and pool chemicals. The finger and toe entrapment gap is a bit more complex but is important to resolve as most grates in the field were built with the .375 gap, not the new .315” (8MM) gap. MORE IMPORTANT is that most free form Perpendicular grates (see photo above) simply CANNOT have the correct gap by virtue of their design and installation, and we recommend that these be updated in the near future. The new CES perimeter grating is the ONLY system that assures compliance for all 3 above on all pools including curved or free form grating.


What are your normal responsibilities? The big ones are, a) routine inspections, b) periodic maintenance, c) assuring the existing grates meet current and future guidelines. Unless you want to become a code expert, you should look for solutions that are both NSF® certified, and IBC (International Building Code) certified.


How can we help? First by providing this white paper, we hopefully helped make you aware of any potential issues, Second, you can contact our team to assist you in evaluation of any potential issues, and help find a solution, and Lastly we are ready to provide a cost effective solution using our versatile line of perimeter deck including design, supply, and installation assistance.


One final note…. many of our customers have VGB (below the water line) pool grates that are now over 10-years old. The VGB act REQUIRES that you change these grates to retain compliance with the Federal Act. While DOH and others might help with inspections or notices, it is ultimately your responsibility to make sure that these grates are complaint. Please let us know if we can assist you in any way.

So many options - So little time!

By popular demand - A quick review of
Popular Chlorination options

Chlorine (or alternative) is a mainstay of any responsible treatment program, and is here to stay! Even if you use a wide variety of supplemental treatment options, you still need to provide some form of chlorination to comply with state and national health codes, prevent Cholera and other nasty issues, and assure a safe and appealing pool water for your patrons and guests. 

Per your request here is a quick review of all the popular alternatives along with some positive and negatives:

Sodium Hypochlorite: Popular in the 1980’s as an alternative to gas, it is a prevalent form of chlorination, but the use is on a downward trend. Depending on your fill water, it can be used with Co2 or Acid pH feed systems. The cost varies widely with the size of the deliveries, and your location, but costs less per pound than all other alternatives. Issues include feeder maintenance, heavy dependence on pH correction, and does not address all the other chemicals that need to be added in order to prevent aggressive water from destroying your pool finish and heaters, etc. Pool water must be dumped to avoid salty taste and some irritation.

Calcium Hypochlorite: The Pulsar brand has been around for 25 years, and is a popular All-In-One solution, providing all the Chlorine, Calcium, Bicarb, and even some stain prevention in a self-shocking feeder. Tablets are convenient, and can resolve some on site delivery and storage issues. Tablets cost more but it uses 1/10th the acid of some bleach, and provides savings over required adding of all the other chemicals, and the water quality is great. 2018 Feeders are now self cleaning, and easy to operate, so this is a rising alternative among pools of all sizes.

Trichlor Tablets: Was prevalent in the 1980’s, especially on smaller commercial pools. Tablets are convenient, but it has
fallen out of favor since it leads to quick and continual over-stabilization, and requires you to continually dump your pool water. Cannot meet CDC guidelines for fecal accidents >16 PPM, so dumping most of the pool water
after any accident becomes a major science project. Alkalinity reduction requires constant addition of Bicarb, so this is rapidly falling off the radar.

Saline Chlorination: Many folks seem to love the “mineral pool” feel. Wildly popular on residential pools and totally butchered on many earlier commercial applications. CES has a solid 12-year track record with 100% success rate, but it requires a serious installation of institutional-grade equipment, automatic control of pool water salinity, good service and a knowledgeable approach. It is normally self-funding with quick payback, and the reaction chambers last 3-4 years, so it's a viable long term alternative. Best used with redundant cal-hypo feeder to provide the most cost effective installation cost, and guaranteed performance regardless of bather load or weather.

Nex-Gen: This unique skid mounted package makes Chlorine out recycled pool water. Wheel it in, plug it in, and make your own. Unlike saline, the salt is not added to the pool but is added to the process, so the pool salinity does not really provide the “mineral pool” experience. Popular with stainless pool applications, and can treat multiple pools with one feeder. This self funding alternative often incorporates a redundant feeder for quickest payback, and the popularity is on the rise.

Supplemental Oxidation: Most popular types include Amalgam UV, Medium Pressure UV, and Ozone.. or combinations thereof. Quicker and better than Chlorine in killing some undesirable organisms, but still requires the use of some form of chlorination. Constitutes a pool modification, which means engineering, permits, etc, and requires annual maintenance and periodic lamp replacements, or it will cease to work.

Fortunately, CES has accumulated 35 years of experience in all the above, so we can help you make an educated chlorination decision based on YOUR preference, not ours.

Please let us know if you would like to revisit your chlorination strategy, and we will gladly work with you to find the best alternative for your facility.


New MAHC Code gets 115 Peer-reviewed updates for 2018

The Model Aquatic Health Code (MAHC) is taking the national (and international) pool code world by storm. It is the ONLY peer-written and regularly peer-reviewed code in existence and is being adopted as a best practice pool code or primary Pool Code all around the US and beyond. During the 2017 MAHC conference there were 168 new suggestions to make the best even better, and those were voted on by the CMAHC (industry folks like you and us that review and get to vote on all changes).

Now just months later, we are proud to announce the release of the 3rd edition of the MAHC which incorporates 115 of the 168 suggestions made. There was also an update to the MAHC Annex - a parallel document that provides all the technical details, formulas, and other justifications behind the code excerpts. Here is a quick synopsis of the changes for your reference.

Why is the MAHC so unique? Well if you assemble hundreds of the brightest minds in the pool industry including health department officials, academia, manufacturers, experienced pool contractors, engineers, and service companies… all with thousands of years of field experience, and you coordinate an effort to write the “best of the best” codes…. the results are going to be great!

Then, add a periodic review with a formal tabulated vote from hundreds of voting members of the CMAHC, and the best continually gets better.

CES strongly endorses the MAHC and uses it as a best practice reference when working within Florida, as we are lucky to have one of the better health codes in the US. When we are working outside the state and in the islands - where the codes aren’t as strong - we rely almost completely on the MAHC to help guide our equipment designs and operational guidelines.

Please let us know if you need more information on the Model Aquatic Health Code or if we can assist you in any way.


Important safety regulations that fly under the radar.

Pool safety for patrons and operators is rightfully one of the top concerns in today’s sue-first society. Most lawsuits drag in everyone - owners, operators, managers, sub-contractors, & suppliers - and let the courts split up the responsibility and the payments. It’s best to avoid the situation altogether, heh? 

While some safety items are apparent, some fly under the radar. Here are a few tips to help you steer clear of trouble:
Below the water: VGB - Virginia Graham Baker Act…its baaaaccckkk. Yes, VGB is 10-years old for most, and many owners have forgotten that all drains and covers had an “expiration date” and that they had to be replaced in order to maintain compliance. While some covers and drains had 2 or 5-year expiration dates, CES tended to market models with 10-yr expiration dates, and those are now due.

Why is this important? A federal regulation MUST be followed, and any hair or limb entrapment - or even worst - could put all involved at huge risk.

Above the water: Perimeter overflow grates are also a source of great liability. There are strict legal requirements to maintain a 8mm (millimeter) gap consistently in order to prevent finger and toe entrapment. Many perimeter grates on free form pools do NOT comply with this regulation.

The solution? New Daldorado parallel replacement grates finally resolve the long-standing issue with compliance.
SVRS devices need ongoing testing and certification: Suction Vacuum Release Systems are used on pools where gravity surge tanks were not implemented, and they are tasked with breaking the pump suction in the event that someone becomes trapped on the main drain. While there is much evidence that they don’t work fast enough to prevent evisceration, many were installed in lieu of other safety devices.

The problem is that these devices need to be continually tested and certified. They are mechanical devices that can and DO fail, and thus are giving owners a false sense of protection. The best way to protect yourself is through a gravity feed surge tank.
In any event, compliance with VGB and above water grates are very important, and need to be addressed in order to prevent your facility(ies) from severe risk.

Please contact us with any questions or comments, and let us know how we can help.

Has Robotic Pool Cleaning finally come of age?

Years ago many discarded the use of robotic vacuums as unreliable and a general pain in the rear. The units, while cheap, were problematic plastic gizmos that seemed to spend more time in the shop than on the pool deck. As such, owners had to have known several ways to clean their pool in order to handle the task, and sometimes they would even own several robotic vacuums AND a backup system.

A lot has happened over the years to further complicate the discussion:
Harder to clean: It is getting harder and harder to find people to reliably vacuum a pool BEFORE the swimmers invade the pool in the morning. Many facilities either clean the pool one section at a time, taking several days to complete the entire pool, or only vacuum the pool once or twice a week at best. Sometimes the vacuum pole does even reach the middle…what’s up with that? If the pool WAS being manually vacuumed, many have figured out that it is real expensive - costing $500+ dollars a month.
What’s living in your bottom: At the same time, more and more research has been done pointing out that a bunch of nasty creatures are living on walls and bottoms. European research has detailed tens to hundred of thousands of colonies of bad stuff living in a typical dirty bottom. So, vacuuming is more important than ever, and tougher to get accomplished.

Fixing the reliability issue: In the past 25 years the robotic cleaning market in Europe has evolved much quicker than the US market. Finally, now in the US there are a handful of new alternatives for reliable robotic cleaning… that are fully maintained ON THE POOL DECK. Enduro cleaners have passed the test over the past 6 years of operation in the US, and the past 30-years of operation in Europe. Hundreds of CES customers can vouch for reliable operation with little or no down time.

Fixing the affordability issue: Still getting a reliable robotic vacuum is similar to getting a large color copier/scanner/binding machine for your office. The good ones cost more, and few are going to budget for a capital purchase. BUT almost every company as a similar copier in the office. How? ….as a part of a maintenance program. Using the same strategy hundreds of CES customers are using the “no worries plan” starting at $199 per month for the vacuum, with ALL proactive on-site maintenance and ALL parts and labor for any potential repair. So far we have not found a cheaper and better way to clean a commercial pool

What else customers have learned:

Robotic vacuums clean better: Whenever we have performed a demo directly after a thorough cleaning, the cleaner has always picked up a bag full of dirt in a few minutes. Everyone has been surprised, and now know that a machine with active scrubbing cleans better than just vacuuming.

Daily cleaning is better: Another finding has been that if you have a reliable vacuum, you use it more often, and more customers are cleaning their entire pool on a daily basis. On these sites we have seen a noticeable reduction in chlorine consumption - maybe because there is less loading.

Many agree that Robotic Vacuuming has truly come of age. The need is more than ever, the alternative cost is higher than ever, and the Enduro and Peps products have proven that reliable on site maintenance programs resolve the other issues. There’s one quick way to check if it might be right for you? Sign up for a no-cost demo, and let’s see if a robotic cleaning solution might be right for your site.

PFD program has saved well over $2-million off customer's electric bills.

In the past 5+ years, CES Motor Control Centers (both the larger MCC-VFD, and the smaller PFDx) have become a favorite among pool owners, operators, and pool builders.… and even the power company.
Why? There are several reasons, but one of the easiest to calculate is that we have CONSERVATIVELY helped save over $2-Million dollars in electrical costs for customers. This is based on having installed over 4,000 horsepower of energy saving devices all over the US and the Caribbean, saving nearly 20-million kWH of power, and applying an ultra-conservative average power cost. At our current rate, CES customers are now saving over 32,000 kWH per day.

These systems are unique in that they are the ONLY control system where you dial in the EXACT (DOH) Department of Health-required flow rate on the chemistry controller, and the system accurately and reliably provides the precise flow rate 24/7/365. This continually MINIMIZES power consumption, and the savings on clean filters are a lot more dynamic than anyone ever imagined. FPL’s review at one site showed clean-filter savings at an average of 42% of normal power. Many customers have also programmed OFF-PEAK flow rates automatically, running their pump at 12.5% of normal power, while still filtering, heating, and treating - all within approved DOH guidelines.

One customer alone is saving over $100K a year in electrical costs on their 27 pools as highlighted in a recent magazine article. Their game plan was so good, that FPL gave them $10,000 to convert their pools. How can you beat that?

What are some of the additional benefits?
Bonus savings: The power company actually has two major charges, the one based on amount of kWH used (savings calculated above), and a “demand” surcharge based on the peak consumption used which is applied against every kWH used. By limiting the peak rush with “soft start” of pumps, demand charges are dramatically reduced, thus helping saving thousands of additional dollars a year across your entire bill.
Pump Protection: All CES MCC-VFD cabinets are equipped with advanced pump protection packages including protection against low power, high power, and temporary loss of phase — all which have a track record of destroying motors, and causing expensive repairs.

On-Site Service: Many folks have been soured by energy saving “gizmos” that never performed per their unrealistic claims, but not CES customers. We provide accurate and realistic savings estimates, and have maintained responsive on-site support - stocking all the parts and technical know-how to keep your energy saving systems working great - year after year. 

Peace and Quiet: Running a pump with the precise amount of power not only saves energy, but saves heat, motor life, and noise. Your pumps hum, not scream, and you get diminished complaints of hot and loud equipment rooms.
Perfect code compliance: Besides energy savings, these pools are always maintaining the perfect flow rate, so the filters work better, the pool is cleaner with less down time. A win-win for all.
Self-funding: These programs don’t really cost much to implement, but actually save more money than they cost on a monthly basis. Many customers have implemented these on a self-funding program, and modernized their facilities, gone green, and saved tons of money all at once.

There some new wrinkles to the CES program being introduced every month, and the newest PFDx features allow you to implement self-funding programs on smaller systems and feature pumps including your spas, wading pools, Interactive Water Features (IWF’s), and more.
