When a hot summer day hits, is there anything more fun and refreshing than playing in the water? Throughout communities across North America, splash pads are becoming an increasingly popular alternative for traditional outdoor aquatic centres like swimming pools and wading pools. They are typically located at municipal parks, water parks, and resorts, but they can be found almost anywhere. The growing demand for splash pads is not surprising, as there are several significant benefits associated including cost savings, accessibility, flexibility and more!
NO LIFEGUARDS REQUIRED
A major advantage of splash pads is that lifeguards are not required. This is a big savings and allows smaller communities to install a splash pad in place of a pool to help cut back on running costs.
ATTRACT THE COMMUNITY
One of the largest advantages of a splash pad is their visual appearance. Even a limited number of water features can help draw people from the community to parks and pools alike. With endless options for water features and interactive toys splash pads can be a simple attraction for anything from a community pool to a campground or park. Splash pads can also be an effective way to attract members of the community to public areas such as public parks or community centers.
With the way splash pads are designed there is no additional accommodations or equipment required for accessibility. With a pool, costly lifts or large ramps are required to meet accessibility standards, though with splash pads being on grade there are no issues getting onto the pad. Along with access to the pads, because users are not submerged it is much easier for someone in a wheelchair to enjoy the splash pad.
In most cases, communities do not charge admission for splash pads, as this is a good way to give back to the people of the community. A splash pad is an easy way to provide somewhere to cool off without the costs of building a pool. Splash pads are also highly appealing to small children and toddlers who are too small to touch the bottom of a pool.
Splash pads can be made in any shape or size desirable, and this allows for endless flexibility for locations where splash pads can be built. Splash pads can be added to existing developed areas where there would be no room for a pool. Many splash pads do not recirculate which means the mechanical equipment required can typically fit into a small cabinet. This allows for a splash pad to be built basically anywhere as no underground tanks or mechanical rooms are required.
Since the majority of splash pads do not recirculate the water used in the system, there is minimal maintenance needed for the pad. In this situation, chemicals are not used for the water, and an operator on staff is not required as the system only needs to be checked periodically.
Since the primary target of splash pads are children, safety is obviously a big concern and this is where a splash pad really shows advantage over a wading pool. Splash pads do not have any standing water, which eliminates any worry for those who are too small to swim, allowing them to enjoy a splash pad all on their own.
Your swimming pool can be a wonderland of fun and adventure. With the new and classic choices available, you have the ability to change the atmosphere from day to day simply by using different water toys. As a child growing up with a pool, nothing was more exciting than going to the pool store and looking at the new trendy toys. The options available today would blow my younger self’s mind.
Pool sports and games are great fun for family and friends. A volley ball net allows for a large group to come together and play. With the ability to rotate in and out of the game, everybody of all age groups gets a chance to play. If you are looking for a more competitive game, poolside basketball and water polo nets are great options. There are even multi-use systems that combine games like volleyball and basketball. A cost-effective way to add more variety to your sport options.
INFLATABLE POOL TOYS
Todays inflatable toys have come a long way from what the options available when I was a kid. If you wish to relax and have some time for yourself, there is a limitless selection of mattresses, tubes, boats, themed floats, and lounges. Many inflatables have added games into the design, like Pongo Bongo or have built in water guns to turn your inflatable into an afternoon of competitive fun. Larger inflatable lounges and couches that can accommodate up to six people are also available - complete with built in coolers and cup holders. What a fantastic way to spend a lazy Sunday with friends! Options for little ones have expanded as well. The classic water wings are always available, along with a variety of floating seats with sun umbrellas, larger inflatable islands, play structures, wheels, slides and more - the choices are endless!
Pool toys can keep young ones (and even the young at heart) busy for days on end. Dive toys are available in a variety of shapes and sizes, allowing young swimmers to use their imagination to create new challenges. Also available, the “Aqua-Zooka” can shoot up to 50 feet and turn a regular water fight into a no holds barred battle. It’s amazing that no matter how old you get, soaking somebody with a water gun is still a blast!
Aquatic Exercise has become popular as a low impact fitness approach. The ability to swim with a deck mount tether or deck mount flow generator gives you the benefits of long distance swimming without the need for an Olympic sized pool. If aquatic exercise is what you enjoy, there's even treadmills and stationary bikes designed for use in pools. This is a terrific way to get the exercise without the hard impact on your joints and back. Foam weights are another amazing way to exercise by allowing buoyancy to create the desired resistance without the heavy impact of regular weights.
When it comes to choosing the best water toy for you and your family, the sky is the limit. The best part? You can choose more than one!
The Ontario and other provincial Building Codes have minimum standards that have been established to ensure that new public pools are constructed to be safe and functional. Following construction, Health Departments are responsible for monitoring and regulating the operation of the pool. The entire content of the code is important, but some items really stand out. For example, strict adherence to the velocity of water moving through suction fittings like the main drains is really important. The velocity of water through main drains is dictated as not to exceed 1.5 fps (feet per second). This low velocity helps decrease the possibility that people might become entrapped or entangled by the main drain fitting.
Another really important factor is the turnover rate of the pool. For Class ‘A’ pools (a pool to which the general public is admitted), the entire volume of the pool has to be filtered and chemically treated every four hours. This ‘turnover rate’ provides some assurance that the pool water will be clean and safe for bathers to use. The Building and Health Codes are very important and have elements that work to ensure pools work really well and up to standards, most of the time. As with most rules, there are some exceptions that should be considered. An important question to consider is: When is it a good idea to do more than what the code calls for?
CLASS A & CLASS B POOLS
In Ontario for example, a Class ‘B’ pool (a pool operated on the premises of an apartment building with five or more units, a pool operated as a facility to serve a community of more than five single-family private residences, a pool operated on the premises of a hotel, a pool operated on the premises of a campground, a pool operated in conjunction with, a club or a condominium, a pool operated in conjunction with a day nursery, a day camp or an establishment for the care or treatment of persons who are ill, infirm or aged) is required to be designed in such a way that the circulation system exchanges the entire volume of the pools water once every six hours, or four times per day. Most of the time, this is totally acceptable, but there are times when it is not sufficient. At some resorts for example, the pools are shallow and the volume of water is small. This coupled with a very high usage, warmer water and bathers who may not shower as well as they should (especially children) can create a condition that makes the water quality very difficult to manage. We often oversize the circulation systems with larger than required pumps and filters in this instance and add secondary sanitation systems like UV to help ensure superior water quality.
The same is true of a Class ‘A’ pool. These pools are required to be designed to exchange the water in the pools every four hours or six times per day which seems like a lot, but again there are some exceptions. If the pool is a therapeutic pool with a higher percentage of elderly users, or users with either a physical or mental disability, there may be a higher risk of contamination by fouling, making it prudent to exchange the water more often and install UV systems. For pools like this we often design the mechanical system to exchange the water every two hours, or 12 times per day, or more.
Another important consideration is the filtration rate of the pool filter system. In all cases this is calculated by dividing the total flow of the circulation pump by the total surface area of the pool and is expressed as GPM/FT2 of filter area. For sand filters, most manufacturers call for a filtration rate of no more than 15 GPM/ FT2. For a pool that has a flow rate of 450 GPM, the total sand area should be no less than 450 GPM/ 15 GPM/FT2 = 30 FT2. This square footage can be achieved by either using one or two larger horizontal or vertical filters, or a ‘battery’ of smaller filters. Is a filtration rate of 15 GPM/ ft2 always enough? For a lesser-used pool with a lower-risk user, and a low bather load, the answer is probably yes, but in instances where there is a high bather load, it may make sense to lower the velocity of water through the filter to improve filtration even more. Sometimes it makes sense to oversize the filter so that the filtration rate is more like 12 GPM/ft2. The same thing can be done with other filter media like cartridge filters or DE (diatomaceous earth) filters.
UV SANITATION SYSTEMS
UV is a secondary sanitizer that effectively renders most bacteria unproductive (and therefore safe) as water passes through the device. UV units are not required by code for pools (UV is required for splash pads) or spas, but may be a really good idea to install anyway. Some bacteria are resistant to chlorine or bromine and can become the source of an infectious condition that can make swimmers sick. This can result in a severe and widespread illness outbreak that could have long term effects or even cause the death of a vulnerable individual. There could also be legal implications for the owner/operator of the pool. Even though the codes do not require it, putting UV systems on a high bather load or high risk pool is a smart and proactive change to make.
Finally, the codes are an effective way to improve the overall safety of pools across the community. As with all rules and regulations, not every scenario can be addressed. It is best to look at the particular conditions surrounding your pool and design it appropriately. Since there is no specific ‘rule book’ to help you decide when code requirements should be exceeded, it is best to consult an aquatic consultant or pool builder who has a long record of experience with a variety of public and private pools. These experienced companies will help you design, build or upgrade a pool that is safe and fun for your clientele.
Most pool owners and operators have heard the term VGB compliant as it relates to main drains in swimming pools, and may have heard of the Virginia Graeme Baker Pool and Spa Safety Act that was brought into legislation in the United States.
As a member of her community swim and diving team, Virginia Graeme Baker was a strong swimmer who could swim unassisted at only 3 years old. Despite this, Virginia (called Graeme by her family) died in a spa (hot tub) after becoming trapped on the single main drain fitting of the spa, even with the frantic efforts of her mother, Nancy Baker to release her from the drain. Eventually, two men were able to release Graeme from the drain, but exerted so much force that the main drain fitting was actually broken in the process. At the very young age of 7 years, Virginia Graeme Baker died from drowning as a result of becoming entrapped on the main drain fitting of the spa.
MAIN DRAINS & THE RISKS
The danger of a single main drain in a pool or spa cannot be overstated; when a single main drain is covered and is the sole source of suction for a pump, a tremendous hold-down force is exerted on the person covering the main drain fitting. For a typical residential pool or spa with an 8” round drain, the hold-down force can be in the order of 739 pounds! Even the strongest person would be unable to overcome this kind of force. The larger the surface area of the drain the greater the force, even if the same pump is used. For a 9”x9” main drain, the force will be about 1191 pounds, and for a 12” x 12” main drain the force will be a whopping 2117 pounds! This is approximately the same weight as a skidof bricks! But becoming entrapped by the suction is only one of the dangers of an improper drain installation. People can also become eviscerated if they sit on an improper drain, or become entangled (hair and jewelry) if the velocity of water through the drain is too high, or the drain openings are improperly designed.
Following Graeme’s death, Nancy Baker worked tirelessly as an advocate for pool safety and through the political clout of her father-in-law, former Secretary of State, James Baker III, and in association with Safe Kids Worldwide, lobbies to congress to bring into law the mandatory use of anti-entrapment drain covers and other safety devices and methods.
Use VGB Compliant Main Drain Covers
Perhaps the most important change was the nature of the drain cover itself. Main drain covers are now required to be VGB compliant, meaning that they have a shape and openings that have been designed to dramatically decrease the likelihood of a person becoming entrapped. The drains are also sized for different flow rates so that the velocity of water moving through the surface of the grate does not exceed 1.5 feet per second. This low velocity decreases the likelihood that things like hair will be drawn into the grate creating an entanglement problem.
Use Multiple Main Drains
Another important safety measure in pools and spas is to never have a single main drain. In Canada, it is law that every public pool and spa have at least two main drains, and that these be spaced apart from each other by at least four feet (1.2m). If one drain fitting is blocked, the water has another path to go though (the other drain fitting) so that an ‘absolute’ vacuum cannot be achieved.
Use a Safety Vacuum Release System
Finally, another measure to improve main drain safety is the use of Safety Vacuum Release Systems (SVRS). These devices are installed on the suction side of the pump(s) and are designed to eliminate the suction force of the pump. There are generally two types (mechanical and electrical) which are designed to sense excessive suction and act to relieve this suction. Electrical units work by shutting of the pump, and mechanical systems work by allowing air to enter the pump so that it loses suction.
Swimming pools and spas provide a tremendous amount of fun, leisure, exercise and therapeutic benefits to families, the public and patients. But we have to always remember that pools are really machines designed for our aquatic needs, and like all machines, pools have inherent dangers that have to be managed. For decades, we drove cars without the benefit of seatbelts, airbags and so many other safety features. At one time, we didn’t even have windshield wipers! Thanks to the efforts of Mrs. Baker after her loss of Graeme, properly designed pools and spas are now safer than they have ever been.

There are a lot of considerations when selecting a swimming pool contractor to build your pool. Whether the project is a high-end residential project or a multimillion dollar waterpark, it is important to be very diligent in selecting the builder to avoid delays, cost overruns, improper construction and lots of headaches. But what things should be considered?
WHAT DOES THEIR SAFETY RECORD LOOK LIKE?
The safety record of a company should be a primary consideration. A company with a poor safety record attracts a lot of attention (not the kind they want) and can really bog down a project. In fact, a project can be put on hold for an extended period if there are glaring safety infractions or heaven forbid a serious injury or fatality on the job site. Ask the proponent for a copy of their Health and Safety Policy, and safety record. If they don’t have one, or are unwilling to provide information, move on.
PRICE ISN'T EVERYTHING
Price, while always an important consideration is not everything. We frequently hear our clients say “…I wish we had gone with the more reputable builder. This job has become a nightmare…” The saying “you get what you pay for” could not be truer. If the price seems too good to be true, it is. There is no such thing as an extraordinary $7 bottle of wine, and there is no such thing as an inexpensive Bugatti car. The two things are mutually exclusive. The Bugatti and a K-car will both take you to the store, but the Bugatti will take you to the store for decades (and look really good doing it!), and there is no comparing the quality of the two. The same is true in pools. You can choose a method and a builder that may appear to save you a little coin but suffer endless change orders and additions to the project. Or you can spend that little extra bit of money to hire a thorough and reputable builder and have peace of mind for years to come.
DO THEY HAVE A STRONG FOUNDATION?
Like a strong building, a strong company needs a strong foundation. In the construction business, this foundation is in the form of knowledge that is both deep and wide, and can only be acquired from years of experience specific to the industry. A newer business just doesn’t have the history to be as knowledgeable as a well-established company that has been around for a long time. In the experienced company, there are senior people and younger members of the team. There is a combination of high energy and drive and a deep well of information that was developed over decades of practice. The thing about knowledge is that it is often applicable to a wide variety of applications that help experienced builders provide the best outcome for the client. Hydraulic concepts in pools and water management for example, are often applicable to electricity where Voltage equates to Feet of Head and current flow to velocity. Companies who have a deeper knowledge in their art have a broader understanding of the many things they may encounter in performing their work. Look for contractors who have a broad range of experience over a long period of time, senior people who have “been around the block” a couple of times and young energetic and well educated project people.
DO THEY HAVE INTERNAL SYSTEMS IN PLACE?
It is a great thing to have knowledge, but if it is held by a few individuals it often fails to crystalize in the positive outcome of your project. Good companies develop internal systems that reflect the Best Practices that have been developed out of the knowledge gained from experience. It is these companies who seek to establish a culture of quality and caring expressed in writing the form of standard operating procedures. Ask your potential contractor if they have internal systems in place to support quality assurance, delivery, and value added designs, longevity of the product, and so on. A company with systems is a company that cares about what they do, and who they do it for. Also ask if the company has a Mission Statement. The Mission Statement is the guiding philosophy of the company. A company without a mission is like a pilot without a map. Yes, the plane is flying…but the destination is dicey.
WHAT IS THEIR EXPERIENCE LEVEL?
The Record of Experience speaks volumes about the knowledge base of the company. Obviously, the more pools a company has built, the more experience they have. But it is also important to look at the different types of pools that a company has built. Not all pool builders build all pools, and sometimes for good reason. For example, Company ABC may be an advocate for cast-in-place pools through their limited knowledge and experience; they know how to build them, but nothing else. Concrete pools are really good and are considered the gold standard in the industry, however, there are times when another type of pool is more appropriate than a concrete pool. If the pool is going on the top floor of a high rise, weight may be a limiting parameter. It is important to find a builder who has the experience to recognize and understand your options and what best suits your needs. Ask your potential builders for their list of projects (current and complete) and also for a list of references. If the record of experience is small or limited in scope, you may want to look a little deeper into the company. If the reference list seems small compared to the record of experience, it should raise a red flag! A good contractor doesn’t maintain a specific reference list…every single client should be a reference.
DO THEY USE THEIR OWN FORCES?
If the builder you are looking at using has a lot of subcontractors, it may be worth looking a little further. Dividing the scope into different trade subcontracts (mechanical subs, waterproofing, tile, concrete etc.) dilutes and displaces responsibility of the trades and of the general contractor. When something goes wrong, it’s nobody’s fault, and it’s everyone’s fault. A great deal of time is spent trying to figure out if the waterproofing contractor caused the leak, or if the tile contractor damaged the waterproofing. Or maybe the concrete contractor is at fault. It is best to source a contractor who self-performs the entire pool scope with their own forces from the excavation, to mechanical and electrical work, to tile setting and commissioning and training. When there is only one company performing the entire scope for the work, there is no opportunity to cast blame for problems to others. You only have one phone call to make.
ARE THEY FINANCIALLY STABLE?
The financial stability of the company is also an important consideration. Are they able to completely bond a large project? Often tender documents ensure that this is the case, but private projects may overlook the need. What happens if things go wrong, or the contractor walks off the job or goes bankrupt? Who will finish the job? Who will pay for the work? Also, you want to be sure that the company you select is going to be around tomorrow and for years to come. Of course, there is never a guaranty but the best predictor of the future, is a record of the past. If the company has been building great pools for decades, they are likely to be around for a long time to come.
DO THEY HAVE A SERVICE DEPARTMENT?
Once the pool is built, you are away to the races. But what if something goes wrong with the pool after a few years? Who will close the pool for winter? It is always best of the company you choose to build the pool also has a service department who can deal with any problems and to perform regular maintenance. The service department of the company who built the pool is best equipped to service the pool since they will have an intimate knowledge of the pool from the construction phase. There are many “pool builders” out there who actually have no idea how to best operate a pool, and have no service department. It is best to steer clear of these builders. Once the project is complete, you never see them again.
CAN THEY PERFORM?
Finally, schedule can be critical, especially for commercial projects. Liquidated damages can cripple a business that was counting on opening the pool in December, but it didn’t happen until the following May. There has been more than a few projects abandoned or sold for pennies on the dollar as poor performing contractors drove the owner into insolvency. No builder is perfect or immune to making mistakes…things happen. What sets the premium builder apart from others is how they react to the problems. The only way to know how different builders react is to speak with their past clients. Don’t accept a short list of “preferred references”. It is a lot of work to fully research your builder, but it will pay dividends many times over in the long run.
A well-constructed pool delivered on time and on budget will provide decades of enjoyment, or in the case of a commercial project, revenue generation. The best start to this positive outcome is to balance all of these considerations discussed, and make a good decision.
