    1. Virginia Graeme Baker Act Waterpark Industry

    2. Overview We support the goals of the Act Single, blockable drains should comply with the Act. Water attractions are not traditional pools Waterparks currently employ multiple layers of anti-entrapment features Applying ANSI/ASME A112.19.8 to water attractions is not appropriate. It creates technical & operational issues, which may result safety hazards. Applying ANSI/IAF-9, ASTM, and other technical standards is a viable solution

    3. Waterpark Industry Outdoor and indoor waterparks – more than 1,000 waterparks in North America Over 85 million in attendance annually growth average 3-5% each year Communities served – Private companies large and small Municipalities Hotel Resorts Community Centers Suppliers & Manufacturers Body of professionals dedicated to waterpark safety standard writing (ASTM and ANSI) Employee base ranges from 20 to 5,000 persons per park Many parks will be open December 20th going into the busiest part of the year.

    4. What is a typical swimming pool?

    5. Virginia Graeme Baker Act – Definition of Swimming Pool or Spa From Section 1403 Swimming pool; spa. The term "swimming pool" or "spa" means any outdoor or indoor structure intended for swimming or recreational bathing, including in-ground and above-ground structures, and includes hot tubs, spas, portable spas, and non-portable wading pools."

    6. Typical Swimming Pools

    7. Typical Swimming Pool & Spa Features Flat water Smaller systems and drains Few walking surfaces Few interactive features

    8. What is a waterpark attraction?

    9. ANSI/IAF-9 Defines Aquatic Recreation Facilities as:

    10. Wave Pools

    11. Activity Pools

    12. Waterslides

    13. Leisure and Action Rivers

    14. Interactive Aquatic Play Structures

    15. Simulated Surf Rides

    16. What makes waterpark attractions different from a typical swimming pool?

    17. Waterparks are complex

    18. Comparison on Dimensions & Use

    19. Unique Features of Waterpark Attractions Large bodies of water Moving, shallow water Walking surfaces Interactive features Use of tubes, rafts, mats Partially submerged skimmers Lifeguards Several anti-entrapment features are utilized Large unblockable drains Gravity drains Multiple drains Water velocities at drains less than 1.5 ft/sec

    20. Circulation grates are larger than 18”x23” (unblockable) and multiple drains are installed

    21. Drain grates are large and designed to achieve water velocity of less than 1.5 ft/second

    22. Gravity Drainage System

    23. Multiple main drains with drain cover centers at least 3 feet apart

    24. Dual Sumps

    25. Drain Grates larger than 18”x23” (unblockable)

    26. Large, unblockable drains

    27. Challenges

    28. Discuss issues with implementation time frames after grates are available. Discuss issues with implementation time frames after grates are available.

    30. Leaves change flow rates Aquastar grate put on an existing 1.5 ft/sec sump results in 5+ ft/sec flowLeaves change flow rates Aquastar grate put on an existing 1.5 ft/sec sump results in 5+ ft/sec flow

    31. Challenge: Even if the cover meets the requirements of the standard, there is a reluctance by licensed engineers to certify existing drain grates. Solution: allow for self-certification? Checklist filled out and maybe submitted to State? Solution: allow for self-certification? Checklist filled out and maybe submitted to State?

    32. Summary 1 - The ANSI/ASME standard was not written with waterpark facilities in mind. 2 - Our industry supports laws that enforce anti-entrapment compliance. Consideration of the unique features of water attractions is needed. 3 - Technical requirements for anti-entrapment should be addressed in other ANSI and ASTM standards specific to waterpark attractions. 4 – Rushing to implement ANSI/ASME 112.19.8 for water attractions may lead to additional unanticipated safety hazards.

    33. Proposed Solutions

    34. ASME Addresses design and testing of drain grates and sumps Defines anti-entrapment based on water flow velocity and drain dimensions Refers to ANSI/IAF-9 for other anti-entrapment solutions Test methods limited to 18x18 grates Written by commercial pool suppliers, manufacturers, consultants, etc. IAF-9 Addresses design and construction of Aquatic Recreation Facilities (waterparks) Defines anti-entrapment features required of the entire system, regardless of drain size. Written by waterpark operators, designers, safety consultants, and suppliers.

    35. Each document presents only a part of the overall system A specific standard is needed to address the unique requirements of drains in water attractions ASTM F24.70 has a task group organized to incorporate the existing standards and address the specific requirements of water attractions. This standard would address the specific challenges identified in this presentation.

    37. Conclusion Although we believe the definition of "swimming pool" and "spa" in Section 1403(6) of the Virginia Graeme Baker Pool and Spa Safety Act does not include waterpark attractions, the waterpark industry wants to do everything possible to meet appropriate safety standards. The waterpark industry currently employs safe anti-entrapment features and practices. Waterparks are unique in design and configuration, with specific safety performance requirements. Therefore, we would like clarification that the Act and ANSI/ASME A112.19.8 does not apply to water attractions so we may work on an ASTM standard WK 21536 to incorporate existing standards and address the specific challenges shown above.  We welcome future inclusion in the Act when appropriate technical standards are developed. The ANSI/IAF-9 standard is specific to waterpark attractions.  It provides flexibility in design without sacrificing safety However, it is only part of the solution. More specific technical requirements are needed to satisfy the requirements in the law.
