Spray parks exude fun—spray cannons, slides, sneaky soakers and sounds—uniting these elements creates a magical water world, which can bring endless joy to visitors for years to come. These facilities are quickly becoming the desired solution for recreational enhancement in a number of communities.
Before the decision to build a spray park is made, it is imperative to make sure the necessary steps are taken to ensure its success. From building materials to design themes, there is a lot to think about. By following the key steps outlined in this article, a designer can create a safe and successful spray park that will make a lasting impression on the community.
While progressing through the stages of the project there will often be times when a critical decision must be made, which can drastically alter the outcome. To make these decisions easier and to ensure everyone involved in the various stages of the project understand the overall goal, it is important to define the key objectives and criteria for success upfront.
Key questions to ask, include:
Although both are essential, decisions will arise where one may need to be sacrificed for the other. Keep in mind, a great looking park will enhance the surrounding environment, but a great looking park, which also offers a variety of interactive play features promoting creativity and imagination, will keep visitors coming back and ensure the park’s longevity.
If the target market spans from toddlers to ‘tweens,’ decisions regarding features and layout will be much different than designing a facility appealing primarily to the seven-to 12-year-old market. In this case, it is important to keep in mind adults may design the facilities and select the features, but it is children who make it come alive. To create a successful spray park, a designer must step back throughout the entire project and be sure to look at the features from the perspective of its target market.
Whether updating an existing facility, enhancing hotel amenities or creating a new public attraction, the spray park will require three essential elements: water, electricity and sufficient drainage. During the initial planning stages it is important to know and understand local public health and safety codes and regulations as they can have a significant influence on decisions made with regards to water usage, feature selection and surfacing.
In recent years, public health authorities have become more actively involved in establishing water quality standards for spray parks. There may also be environmental restrictions on water usage that can affect the overall design. Even if specific standards do not exist, the spray park should be designed in a manner that makes efficient water consumption a priority.
Today’s environment supports three main water management options:
Implementation of a water treatment/recirculating system or a retain-and-reuse system requires advance approval from local public health authorities. Most suppliers will work with the designer to provide the necessary documentation needed throughout the approval process. The time and effort involved in getting approval should be factored into the budget and project timeline.
Today, most spray parks utilize a combination of controllers and activators to sequence the flow of water and to place operation of the park’s features into the hands of bathers. This reduces water consumption, as water only flows when the park is in use, while at the same time it also increases the intrigue and interactivity of the park as kids will try to anticipate which components will spray next.
Before adding a spray park to an existing facility, carefully evaluate the current water management structure to determine if it can even support one. In most cases, the existing pumps and filters cannot handle the increased water flow as water management for a spray park differs from many other applications.
For example, an existing facility may not be able to accommodate the addition of a spray park due to the absence of a manifold or collection tank. Another reason may be a slow turnover rate (e.g. water must be turned over every 30 minutes in a spray park versus every three to four hours in a pool). Understanding these considerations in the early planning stages will avoid unpleasant surprises and budget increases as the project progresses.
Considering water usage is critical in the planning stage, it is also important to understand the water’s source. Does the location have a primary water source readily available? Is it a potable water supply, well water, lake water or some other type of water source? Answers to these questions can influence the overall site plan, as well as the design of the water management solution best suited to the environment. Keep in mind, the typical size of a supply line for a spray park is 51 to 102 mm (2 to 4 in.) in diameter with a static pressure of 0.52 MPa (75 psi).
Is an electrical source readily available at the location in consideration? A minimum of 120 VAC is required to support a potable environment, but these requirements increase to 230 VAC single phase when water treatment/recirculation systems enter the picture. In addition, a qualified electrician will need to be onsite for the installation stage of the project. Ensure this is taken into consideration when creating the budget.
One of the key benefits of a spray park is they are most commonly designed with no standing water. This makes it a safe and fun environment for kids of all ages and abilities; it also generally eliminates the need for a lifeguard. In order to accomplish this, drainage must be planned in the early stages of the project to prevent water from pooling and eliminate unsafe conditions. If the features are being added into a pool or beach-entry facility, lifeguards will be required in the same fashion as a pool.
Not all spray parks are created equal. It is important to consider the facility’s location before evaluating the different suppliers and options, which best meet the project’s unique requirements. Is the environment supervised or unsupervised? Is it a public park located in an area highly susceptible to vandalism? Is it indoors or outdoors?
The answers to these questions will help determine the materials that should be considered when selecting the features. For example, if the facility is located outdoors, near the ocean, in an unsupervised public park, design materials such as stainless steel with a superior paint should be considered as it will withstand vandalism, provide superior UV protection and resist corrosion.
Choosing the right equipment could mean the difference between a successful spray park and a maintenance nightmare. It will also directly influence the amount needed to budget for features. Less durable materials generally come with a lower price tag and a shorter warranty than their more durable counterparts.
While there are many options available for surfacing a spray park, local health codes, American Society for Testing and Materials (ASTM) standards, budget, ongoing maintenance, durability and longevity should be considered when making a selection. The surface of the spray park should be nonporous and non-slip to bacteria buildup and injuries.
Known for its low cost, excellent traction and minimal upkeep, broom finished concrete has been the recommended standard by designers and suppliers all over the world. However, new advances in surfacing options have led to the emergence of brighter colours and unique designs. These can be useful in enhancing the look and theme of a spray park, but they come at a higher price and may not provide the same longevity as a concrete surface.
Stamping, acid etching and colouring can enhance a concrete surface at a more reasonable cost. Keep the project’s budget in mind when evaluating surface options. All too often, projects fall flat because decisions were made to spend precious budget dollars on items, which enhance the esthetics of the attraction, but contribute nothing to the play value. Remember, this is what will keep visitors coming back to the park.
In creating a destination, additional amenities may need to be incorporated into the facility. Local health authorities may require a washroom or shower facility to be available. In addition to this, many parents request seating outside of the spray zone that provides good visibility of the spray park. It is also a good idea to consider adding shade structures over part of the facility and seating areas to offer sun protection on hot days. There may also be opportunities to include revenue generating concessions and activities around the area when building a new facility or when trying to improve revenue generation in an existing facility.
Early on in the planning stages, spray park designers and builders should carefully evaluate the potential site and investigate any external factors that could influence the success of the project. In doing this, the designer/builder will be better prepared to create a budget estimate.
When creating the budget for a spray park, many designers/builders make the mistake of focusing on the features as the primary expense. The features provide the visual impact and play value, however, most of a project’s cost is associated with a lot of other things that go into designing, building and operating the park (e.g. project management, engineering and various approvals). Too often, initial budgets do not adequately anticipate additional costs and as the project progresses, cuts are made to the features or site amenities in order to bring the project back in line. Unfortunately, these elements are what end users value the most; they should be maximized for the long-term success of the facility.
Some key considerations to include in your budget:
Custom themes are what usually set spray park designers apart from one another. While themes may come with a price tag, it can also do wonders in adding flair and continuity to an environment and make it more memorable. It can be as simple as adding a corporate logo, recognizing key financial contributors or as exciting as designing an entire facility around a key theme with creatures, characters, colours and sounds to support the vision.
When planning the spray park’s layout and selecting its features, refer back to the project’s objectives. What demographic is the facility being targeted towards? Understanding how the water sprays from the features and how kids will interact with the water is critical. It is much more than selecting from a catalogue of features, which may appeal to the esthetic design.
If only one age range is being targeted, the job is much simpler. However, it is far more likely the spray park’s design will be geared to a range of children, from toddlers to 12 year olds and possibly older. In this scenario, it is ideal for the spray park to be segregated into three separate areas, each with an activator to allow users to operate each given area.
When designed with a toddler’s needs at the forefront this water play area represents a world of discovery. An abundance of ground sprays with softer sprays and bubblers should define this area. Any upright features should be sized appropriately; quick bursts of water or surprise sprays should be avoided. Toddlers like predictable water and continuous spray displays.
The family play area is generally the focal point of the spray park. It is also where the majority of the larger features and themes should be incorporated. A large central structure, such as a slide, will become the landmark attraction luring children and families into play. Musical features, character themes and spray tunnels are typically found in this area. Components should encourage social interaction and be designed for both independent and group play.
A large mega-soaker dumping bucket or similar structure is a great focal point for this area. Unlike the family play area, cannons and co-operative play elements will dominate this section. Features can be a little further apart, as older kids require more space. Faster actuating ground sprays, more interactive programming (if using a controller) and components requiring cause and effect co-operative play experiences should be considered.
Work with the feature supplier to ensure the design is age appropriate and safety is considered in the layout. Avoid overcrowding the pad with features as it can present safety issues when kids are running through spraying water.
Once the conceptual layout and design have been created, consider engaging the community or key stakeholders in the final decision-making process. All too often the overall design falls short of meeting the kid’s expectations and can result in a non-interactive, non-stimulating spray park.
Involving the community or key stakeholders in the component selection process is a great way to bring more end-user ownership to the spray park, as well as to gather unbiased feedback on which features would best suit the facility.
A typical installation will take anywhere from three-to-eight weeks depending on site preparation, size of the park, selection of water management systems and co-ordination of qualified contractors.
At this stage it is important to keep monitoring progress and ensure installation is being conducted according to the design:
The grand opening of the spray park was a huge success, the facility surpasses the project’s objectives and scores of people are enjoying it everyday. So now what?
Spray parks are not ‘maintenance free.’ It is recommended facility operators/owners inspect their parks regularly to ensure it is operating to its full potential, as well as making sure the site is free of debris and/or potential hazards. Each features’ nozzle operation should be observed for changes in water flow, which can indicate cleaning or adjustments are required.
Mechanical hardware and moving parts need to be checked for wear and tear and water pressure should be measured to ensure it continues to operate within manufacturer guidelines. A safety checklist (provided by the manufacturer) should be followed at every inspection and maintenance records should be kept.
If a water treatment system is in use, the system will need to be checked several times daily to ensure the chemical levels are correct and the system is performing within health standards and regulations.
A spray park is a place to have fun and the planning process should exemplify this. By taking the time to establish the needs of the community and making educated decisions based on long-term goals, it can be easier to build the spray park of everyone’s dreams.
