1. Purpose

The purpose of this document is to provide direction to owners and operators of spray/ splash pads concerning the construction, operation, safety and maintenance of these facilities located within the Niagara region.

There are several risks associated with the use of spray/splash pads. These risks include injuries related to the physical structure and operation of the facility, as well as the risk of waterborne illnesses from exposure to contaminated water.

To reduce the risk of injury, illness or death to facility patrons, it is imperative that the owner/operator of a non-regulated recreational water facility construct, operate, and maintain the facility in a safe manner in accordance with applicable legislation and guidance material, including this document.

2. Structural Design and Construction Considerations

The spray/splash pads should be designed and constructed in a manner that ensures the safety of the users, by following these guidelines:

  • Natural or artificial lighting should be adequate to ensure that all areas within the water contact perimeter (including the main drain/grates) are clearly visible from a viewing point at or near the water's edge outside of the water containing structure
  • All surfaces should be maintained free of potential hazards
  • All surfaces should be made from non-slip material (including stairs) which will reduce the risk of falls
  • All spray/splash pad surfaces should slope to drain
  • No spray/splash pad surface should slope more than 8% (8 centimetres down for every 100 centimetres in length)
  • Where water is allowed to be retained for a short period of time, the depth of the retained water basin should not exceed 15 centimetres
  • If the water collected at the base of the pad takes more than 15 minutes to drain, it should be a re-circulating system
  • Perimeter of pad is designed to prevent water entering from the surrounding area
  • Play surfaces and equipment designed to prevent injury
  • Where playground equipment is installed in the spray/splash pad, it should be appropriate for the water depth. Spray/splash pad owners/operators should follow the manufacturer standards and contact the Canadian Standards Association regarding compliance with the CAN/CSA-z614-2008 Children's Playspaces and Equipment playground safety standards (www.csa.ca)
  • Back-flow prevention devices must be provided on water supply lines
  • All water suction outlets or drains within the water-bearing structure are fitted with anti-entrapment coverings or are anti-entrapment by design, and where appropriate, the suction systems are equipped with a vacuum relief mechanism or another engineered system
  • Where any facility component is powered by electricity, ground fault circuit interrupters are functioning (owners/operators should be advised to contact the Electrical Safety Authority regarding compliance with the Electrical Code)
  • If provided, the water heater temperature is not to exceed 40°C
  • Provisions are made for the safe storage and handling of all chemicals required

3. Water Quality Considerations

All water used in the facility comes from a source that is free of potential disease-causing organisms or harmful chemicals or is treated prior to being circulated to ensure it is free of potential disease-causing organisms or harmful chemicals.

To ensure the water used in the facility is maintained free of potential disease-causing organisms, the water must be:

  • Used once and drained away from the play area within 15 minutes (non re-circulating); or
  • Provided with appropriate filtration and disinfection (re-circulating)

Re-circulating Systems

Where a re-circulating system is used the following specifications must be in place:

  • The circulation system must be running during operating hours
  • Continually refresh the water by discharging 15% of the water directly to waste and adding 15% fresh water whenever water is being circulated to the spray/splash pad
  • There must be a disinfection system that is operated by an automatic dosing device (bromine or chlorine)
  • The water chemistry is maintained in a manner that allows for effective disinfection and comfort to bathers and the water chemistry is monitored by using an appropriate test kit
  • The recirculated water must pass through the following treatment steps:

    1. Filtration
    2. Chemical disinfection with either chlorine or bromine
    3. Retention in a storage tank to allow effective disinfection
    4. Treatment with ultraviolet light (eg. NSF or equivalent approval) capable of rendering cysts and oocysts inactive before water enters the spray/splash pads

    (This is the primary disinfection activity to ensure recreational water is free of microorganisms)

Notes:

  • Turbidity monitoring and control should be in place to ensure that the ultra violet treatment device is effective
  • Ultra violet treatment units should have a mechanism in place to prevent water from being directed to the spray /splash pad in the event of equipment malfunction

4. Safe Operation

4.1 General Guidelines

  • Spray/splash pad area is clean and free from obstacles or items that may cause injury, illness, or death
  • All gratings and covers need to be securely fastened
  • Maintain water clarity to ensure that all areas within the water (including the main drain/grates) are clearly visible from a viewing point at or near the water edge
  • Use of the spray/ splash pad must be discontinued when there is contamination of the water or a health or safety concern is identified
  • Store chemicals so that they are only accessible to the operator

4.2 Supervision

  • Provide sufficient supervision of the facility for the purposes of ensuring safe use and response to adverse events

4.3 Testing Frequency for Recirculating Systems

  • To ensure that the filtration and disinfection treatment systems are operating in accordance with their design, the system should be checked daily one-half hour prior to opening and every two hours during operation
  • Where the level of disinfectant or pH is controlled by an automatic device, the operation of the device should be checked by doing a manual test of the disinfectant or pH in the water at least once a day
  • Where the disinfection level is controlled by an automatic sensing device, the Oxidation Reduction Potential value should be above 700 mV

Maintain a log book

It is recommended that the operator keep daily records of the following:

  • Filtration, disinfection and addition of fresh water
  • Total number of users each day
  • Emergencies, rescues, or breakdowns of equipment that have occurred
  • The daily record should be retained for a minimum of one year

4.4 Emergency Procedures

Emergency procedures for spray/splash pads should be in a place conveniently located for emergency use. It should include the following:

  • Contact information for local fire, ambulance and police services
  • The full name and address of the spray/splash pad (including nearest intersection)
  • If provided, where the emergency telephone is located

The owner and/or operator should maintain procedures in response to emergency incidents (e.g. fouling of water), and train facility staff in the procedures.

4.5 Notices

Owners and/or operators are to post the following signs that set out health and safety rules for spray pad or splash pad users (owners and/or operators may include additional rules that are appropriate for their particular facility).

  • Parents or guardians must supervise their children at all times when using the spray pad/splash pad
  • Children should be appropriately attired for their age and continence ability to prevent fouling the pool
  • No glass containers, food or beverages are allowed in the spray/splash pad area or in the area immediately surrounding the spray/splash pad
