Pool, Spa & Recreational Waters

“Innenansicht des Kaiserbades in Aachen” | Jan Luyken (1682)

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

 The committee has posted a call for public consultation:

ANSI Standards Action | Page 50-52

Proposed revisions involve swimming pool chemicals; a traditional battleground topic in this domain.   Comments due October 14th.

Another consultation regarding pump performance curves is linked below:

ANSI Standards Action Pages 72-73

Comments due October 18th.

A fair question to ask on Issue 160 Revision 4 linked above would be: “Will this raise the cost of pool pumping systems if additional accuracy is required?   Does a stepped up level of flow rate accuracy contribute to safety and sustainability or is it just another product “adder” that few see the incremental cost of?”   

We run into these “bells and whistle” proposals in electrical and mechanical systems fairly frequently.

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. 

We encourage recreational water facility managers in the education industry to participate by communicating with Tom Vyles.  We also host a monthly breakout teleconference on the topic of the twenty-odd water safety and sustainability consensus products that affect #TotalCostofOwnership of education facilities.  See our CALENDAR for the next Water and Sport teleconferences; open to everyone.

Today@ -GMT-4 we break down live public consultation notices on international best practice titles relevant to the technology and management of educational communities in the United States specifically; but also with sensitivity to the global education markets where thousands of like-minded organizations also provide credentialing, instruction, research, a home for local fine arts and sport.

We steer away from broad policy issues and steer toward technical specifics.

A Mathematical Programming Model to Global Supply Chain Management:
Conceptual Approach and Managerial Insights

Panos Kouvelis and Meir J. Rosenblatt

John M. Olin School of Business | Washington University

ABSTRACT: In this paper, we study the design of global facility networks. We present a mixed integer programming model that captures essential design tradeoffs of such networks and explicitly incorporates government subsidies trade tariffs and taxation issues. The resulting formulation can be solved for reasonable size problems with commercially available mathematical programming software. Focusing on special cases of the problem enables us to provide useful insights on preferable international facility networks for various environments. We demonstrate the pervasive, and often dominating, effects of subsidized financing, tariffs, regional trade rules, and taxation in shaping the manufacturing and distribution network of
global firms.:
