Swimming Pool Dimensions and Construction

University of Michigan | Washtenaw County

About Last Night: #Paris2024

A standard Olympic-sized swimming pool is defined by the following dimensions:

  • Length: 50 meters
  • Width: 25 meters
  • Depth: A minimum of 2 meters
  • Lanes: 10 lanes, each 2.5 meters wide

The total area of the pool is therefore 1,250 square meters, and it holds approximately 2,500 cubic meters (or 2.5 million liters) of water.

The organization that sets the standards for Olympic-sized pools is the Fédération Internationale de Natation (FINA) — now World Aquatics — the governing body for swimming, diving, water polo, synchronized swimming, and open water swimming. FINA establishes the regulations for the dimensions and equipment of competition pools used in international events, including the Olympic Games.

The top ten universities that have produced Olympic champion:

  1. University of Southern California (USC)
  2. Stanford University
  3. University of California, Berkeley (UC Berkeley)
  4. University of Florida
  5. University of Texas at Austin
  6. University of Michigan – Michael Phelps, the most decorated Olympian of all time.
  7. Indiana University
  8. Auburn University
  9. University of Georgia
  10. University of Arizona

There are several specific problems that swimming pool overhead lighting aims to solve:

  1. Visibility: Swimming pool overhead lighting is designed to improve visibility in and around the pool. This is important for safety reasons, as it helps swimmers see where they are going and avoid obstacles or hazards.
  2. Aesthetics: Overhead lighting can enhance the appearance of the swimming pool by creating a visually appealing atmosphere. This is especially important for commercial pools where the aesthetics can be an important factor in attracting customers.
  3. Functionality: Overhead lighting can provide additional functionality by allowing the pool to be used during evening hours or in low light conditions. This can increase the usability of the pool and make it more appealing to users.
  4. Energy efficiency: Modern overhead pool lighting solutions are designed to be energy-efficient, reducing the overall energy consumption and operating costs of the pool.
  5. Longevity: Overhead pool lighting must be designed to withstand exposure to water, chlorine, and other harsh chemicals, as well as exposure to the elements. The lighting system must be durable and reliable to ensure longevity and prevent costly repairs or replacements.

Overall, swimming pool overhead lighting is an important component of a safe, functional, and visually appealing pool. It provides illumination for visibility, enhances aesthetics, and improves functionality, while also being energy-efficient and durable.

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 may come into play. 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.

During water sport season the document linked below provides information to illumination designers and facility managers:

NCAA Best Lighting Practices

Athletic programs are a significant source of revenue and form a large part of the foundation of the brand identity of most educational institutions in the United States.   We focus primarily upon the technology standards that govern the safety, performance and sustainability of these enterprises.  We collaborate very closely with the IEEE Education & Healthcare Facilities Committee where subject matter experts in electrical power systems meet 4 times each month in the Americas and Europe.

See our CALENDAR for our next colloquium on Sport facility codes and standards  We typically walk through the safety and sustainability concepts in play; identify commenting opportunities; and find user-interest “champions” on the technical committees who have a similar goal in lowering #TotalCostofOwnership.

AWWA COMMENT PERIOD ON AWWA G480, Water Conservation and Efficiency Program Operation and Management Closes June 23

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.

Backflow Preventer

At the moment no AWWA redlines relevant to our objective are open for consultation.  Several relatively stabilized product standards are marked up but none dealing specifically with interoperability issues.  When they are uploaded you may access them at the link below:

Education communities provide a large market for recreational and therapeutic water technology suppliers.  Some of the larger research universities have dozens of pools including those in university-affiliated healthcare facilities.  Apart from publicly visible NCAA swimming programs there are whirpools in healthcare facilities and therapeutic tubs for athletes in other sports.   Ownership of these facilities requires a cadre of conformance experts to assure water safety.

NSF International is one of the first names in this space and has collaborated with key industry stakeholders to make pools, spas and recreational water products safer since 1949.   The parent document in its suite is NSF 50 Pool, Spa and Recreational Water Standards  which  covers everything from pool pumps, strainers, variable frequency drives and pool drains to suction fittings, grates, and ozone and ultraviolet systems.  

The workspace for this committee is linked below:

Joint Committee on Recreational Water Facilities

(Standards Michigan is an observer on this and several other NSF committees and is the only “eyes and ears” for the user interest; arguably the largest market for swimming pools given their presence in schools and universities.)

There are 14 task groups that drill into specifics such as the following:

Chemical feeders

Pool chemical evaluation

Flotation systems

Filters

Water quality

Safety surfacing

The meeting packet is confidential to registered attendees.  You may communicate directly with the NSF Joint Committee Chairperson, Mr. Tom Vyles (admin@standards.nsf.org) about arranging direct access as an observer or technical committee member.   

Almost all ANSI accredited technical committees have a shortage of user-interests (compliance officers, manufacturers and installers usually dominate).  We encourage anyone in the education facility industry paying the bill for the services of compliance officers, manufacturers and installers to participate.

Meeting Notes in red

Loss of electric power and internet service happens more frequently and poses at least an equal — if not greater threat — to public safety.  So why does neither the National Electrical Code or the National Electrical Safety Code integrate reliability into their core requirements?  Reliability requirements appear in a network of related documents, either referenced, or incorporated by reference; sometimes automatically, sometimes not.

NESC Main Committee Membership: Page xii

Apart from the IEEE as the accredited standards developer, there are no “pure non-government user-interests” on this committee; although ANSI’s Essential Requirements for balance of interests provides highly nuanced interpretation.  The Classifications on Page xiii represents due diligence on meeting balance of interest requirements.

In our case, we are one of many large universities that usually own district energy plants that both generate and purchase generate electric power (as sometimes provide var support to utilities when necessary; as during the August 2003 North American outage).  For University of Michigan, for example, has about 20 service points at 4.8 – 120 kV.  Its Central Power Plant is the largest cogeneration plant on the DTE system.

Contents: Page xxviii | PDF Page 29

Absence of internet service is at least as much a hazard, and more frequent, than downed wires.   Is there a standards solution?  Consideration of interoperability of internet service power supported on utility poles  should track in the next revision.

No mention of any reliability related IEEE reliability standards in the present edition.  Why is this?

Section 2: Definitions of Special Terms | PDF Page 46

In the 2023 Handbook, the term “reliability” shows up 34 times.

Looks like improvement since last edition.  Suggest explicit Informational Note, as in the NEC, using “reliability” and referring to other agencies.  “Abnormal events” could be tighter and refer to other standards for abnormal, steady-state events.   The clarification of purpose is welcomed although a great deal remains uncovered by other best practice literature; though that can be repaired in this edition.

Legacy of shared circuit path standards. Should provisions be made for municipal surveillance, traffic and vehicle control infrastructure.  What would that look like?

3. Utility facilities and functions of utilities that either (a) generate energy by conversion from
some other form of energy such as, but not limited to, fossil fuel, chemical, electrochemical,
nuclear, solar, mechanical, wind or hydraulic or communication signals, or accept energy or
communication signals from another entity, or (b) provide that energy or communication
signals through a delivery point to another entity.

5. Utility facilities and functions on the line side of the service point supplied by underground or
overhead conductors maintained and/or installed under exclusive control of utilities located on
public or private property in accordance with legally established easements or rights-of-way,
contracts, other agreements (written or by conditions of service), or as authorized by a
regulating or controlling body.
NOTE: Agreements to locate utility facilities on property may be required where easements are either
(a) not obtainable (such as locating utility facilities on existing rights-of-way of railroads or other entities,
military bases, federal lands, Native American reservations, lands controlled by a port authority, or other
governmental agency), or (b) not necessary (such as locating facilities necessary for requested service to a
site).

012. General Rules | Covered PDF Page 42

For all particulars not specified, but within the scope of these rules, as stated in Rule 011A, design,
construction, operation, and maintenance should be done in accordance with accepted good practice
for the given local conditions known at the time by those responsible for the communication or
supply lines and equipment

General purpose clause could use some work since no definition of “accepted good practice”.  Refer to IEEE bibliography.

Has anyone confirmed that these tables match NEC Table 495.24 lately?  If it helps: there were no meaningful changes in the 2023 NEC in Article 495, the high voltage article

Section 11. Protective arrangements in electric supply stations | PDF Page 77

A safety sign shall be displayed on or beside the door or gate at each entrance. For fenced or
walled electric supply stations without roofs, a safety sign shall be displayed on each exterior
side of the fenced or wall enclosure. Where the station is entirely enclosed by walls and roof, a
safety sign is required only at ground level entrances. Where entrance is gained through
sequential doors, the safety sign should be located at the inner door position.  (A clarification but no change.  See Standards Michigan 2017 proposals)

The word “reliability” appears only three times.  Should it track in the NESC or should it track in individual state requirements.  So neither the NEC nor the NESC couples closely with power and communication reliability; despite the enormity and speed of research.

 

Energy Standard for *Sites* and Buildings

Addendum av to ANSI/ASHRAE/IES Standard 90.1-2022, Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings. This addendum creates more exacting provisions for envelope alterations. The new format is intended to better communicate the requirements, triggers, and allowances associated with performing an envelope alteration to promote energy efficiency within the impacted area(s).  Consultation closes October 6.

ANSI Standards Action Weekly Edition | Given ASHRAE’s revision redlines are frequently uploaded here

The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is an ANSI-accredited continuous-maintenance standards developer (a major contributor to what we call a regulatory product development “stream”).   Continuous maintenance means that changes to its consensus products can change in as little as 30 days so it is wise to keep pace.

Among the leading titles in its catalog is ASHRAE 90.1 Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings.  Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years.  Free access to ASHRAE 90.1 version is available at the link below:

READ ONLY Version of 2022 ASHRAE 90.1

Redlines are released at a fairly brisk pace — with 30 to 45 day consultation periods.  A related title — ASHRAE 189.1 Standard for the Design of High Performance Green Buildings — first published in 2009 and far more prescriptive in its scope heavily  references parent title 90.1 so we usually them as a pair because 189.1 makes a market for green building conformance enterprises. Note the “extreme prescriptiveness” (our term of art) in 189.1 which has the practical effect of legislating engineering judgement, in our view.
