Water Safety & Sustainability

Harvard University Art Museum | In the Sierras, Lake Tahoe | Albert Bierstadt

The American Water Works Association is one of the first names in accredited standards developers that administer leading practice discovery in backflow prevention consensus documents; usually referenced in local and state building codes; and also in education facility design guidelines and construction specifications.

The original University of Michigan standards enterprise gave highest priority to backflow standards because of their central importance of backflow management to education communities; especially large research universities nested within a municipal water system.  Backflow prevention; an unseen technology that assures a safe drinking water supply by keeping water running in one direction by maintaining pressure differences.  Analogous to the way we want electrical current to run in one direction, failure of backflow prevention technology poses a near-instantaneous health risk for the contamination of potable water supplies with foul water.  In the most obvious case, a toilet flush cistern and its water supply must be isolated from the toilet bowl.  In a less obvious case, but at greater scale, a damaged backflow prevention technology at a university research building can contaminate an host-community potable water supply.

There are other ANSI accredited standards developers in the backflow prevention technology space — the International Code Council, the IAPMO Group and ASSE International — for example.

“The Boys in the Boat”

The Boys in the Boat is a true story based on the struggles and sacrifices made by the University of Washington rowing team to compete at rowing at the 1936 Summer Olympics – Men’s eight.

Joseph Sutton-Holcomb from The Seattle Times writes that author Daniel James Brown got the idea to write this book when his neighbor Judy Willman said that her father, Joe Rantz, was a fan of his works and wanted to have a conversation with the author. That conversation with Joe Rantz about life during the Great Depression led to an in-depth chat about his time as a rower at the University of Washington.

After athletic arena life safety obligations are met (governed legally by NFPA 70, NFPA 101, NFPA 110,  the International Building Code and possibly other state adaptations of those consensus documents incorporated by reference into public safety law) business objective standards come into play.   The illumination of the competitive venue itself figures heavily into the quality of digital media visual experience and value.

For almost all athletic facilities,  the consensus documents of the Illumination Engineering Society[1], the Institute of Electrical and Electronic Engineers[2][3] provide the first principles for life safety.  For business purposes, the documents distributed by the National Collegiate Athletic Association inform the standard of care for individual athletic arenas so that swiftly moving media production companies have some consistency in power sources and illumination as they move from site to site.  Sometimes concepts to meet both life safety and business objectives merge.

The NCAA is not a consensus standard developer but it does have a suite of recommended practice documents for lighting the venues for typical competition and competition that is televised.

Quidditch

The real-life sport of Quidditch was inspired by the Harry Potter franchise but has since changed its name to Quadball.  Organizers hope the name change distances the sport from the social positions of author J,K. Rowling, perhaps growing the sport.

Quadball refers to the number of balls and positions in the sport; its playfield governed largely by field sport codes and standards.

USA Swimming and the National Collegiate Athletic Association Swimming are two distinct organizations that oversee different aspects of competitive swimming in the United States. USA Swimming governs competitive swimming in the United States across all age groups and skill levels, while NCAA Swimming specifically focuses on collegiate-level swimming and diving competitions within the NCAA framework. Both organizations play crucial roles in the development and promotion of swimming in the United States.

Governing Body:

USA Swimming is the national governing body for the sport of swimming in the United States. It is responsible for overseeing competitive swimming at all levels, from grassroots programs to elite national and international competitions.
NCAA Swimming: NCAA Swimming is part of the National Collegiate Athletic Association (NCAA), which governs intercollegiate sports in the United States. NCAA Swimming specifically deals with collegiate-level swimming competitions among universities and colleges.

Scope:

USA Swimming is responsible for organizing and regulating competitive swimming for all age groups and skill levels, from youth swimmers to Masters swimmers (adults). It oversees swim clubs, hosts competitions, and develops national teams for international events.
NCAA Swimming: NCAA Swimming focuses exclusively on college-level swimming and diving competitions. It sets the rules and guidelines for swimming and diving programs at NCAA member institutions.

Membership:

Individuals, swim clubs, and teams can become members of USA Swimming, allowing them to participate in USA Swimming-sanctioned events, access coaching resources, and benefit from the organization’s development programs.
NCAA Swimming: NCAA Swimming is composed of collegiate athletes who compete for their respective universities and colleges. Athletes are typically student-athletes who represent their schools in NCAA-sanctioned competitions.

Competition Format:

USA Swimming hosts a wide range of competitions, including local, regional, and national meets, as well as Olympic Trials and international events. Swimmers compete as individuals, representing their swim clubs or teams.
NCAA Swimming: NCAA Swimming primarily consists of dual meets, invitational meets, and conference championships at the collegiate level. Swimmers represent their respective universities or colleges, earning points for their teams in dual meets and competing for conference and national titles.

Scholarships:

USA Swimming itself does not offer scholarships. Scholarships for competitive swimmers are typically awarded by colleges and universities based on an athlete’s performance and potential.
NCAA Swimming: NCAA member institutions offer scholarships to talented student-athletes in various sports, including swimming. These scholarships can cover tuition, room, board, and other expenses, making NCAA swimming an avenue for athletes to receive financial support for their education.

Steeplechase Water Jump

The steeplechase event requires a combination of speed, endurance, and jumping ability, as athletes must clear the barriers while maintaining their pace and negotiating the water jump. The rules and specifications for the steeplechase event are set by the International Association of Athletics Federations the governing body for the sport of athletics (track and field) worldwide; with minor adaptations by the NCAA for intercollegiate competition.

Emma Coburn | University of Colorado Boulder

The steeplechase is a distance race with barriers and a water pit that athletes must clear during the race.  According to the NCAA Track and Field and Cross Country rulebook, the standards for the steeplechase water jump are as follows:

  1. Length: The water pit must be at least 3.66 meters (12 feet) long.
  2. Width: The water pit must be at least 3.66 meters (12 feet) wide.
  3. Depth: The water pit must have a minimum depth of 0.7 meters (2 feet 4 inches) and a maximum depth of 0.9 meters (2 feet 11 inches).
  4. Slope: The slope of the water pit must not exceed 1:5, meaning that for every 5 meters in length, the water pit can rise by no more than 1 meter in height.
  5. Barrier: The water pit must be preceded by a solid barrier that is 91.4 cm (3 feet) high. Athletes are required to clear this barrier before landing in the water pit.

These standards may be subject to change and may vary depending on the specific NCAA division (Division I, Division II, or Division III) and other factors such as venue requirements. Therefore, it’s always best to refer to the official NCAA rules and regulations for the most up-to-date and accurate information on the steeplechase water jump standards in NCAA competitions.
