Chapter History

The American Society of Plumbing Engineers (ASPE) is the international organization for professionals skilled in the design, specification and inspection of plumbing systems. ASPE is dedicated to the advancement of the science of plumbing engineering, to the professional growth and advancement of its members and the health, welfare and safety of the public.

The Society disseminates technical data and information, sponsors activities that facilitate interaction with fellow professionals, and, through research and education, expands the base of knowledge of the plumbing engineering industry. ASPE members are leaders in innovative plumbing design, effective materials and energy use, and the application of advanced techniques throughout the world.

Worldwide Membership ASPE was founded in 1964 and currently has 7,400 members. Internationally, ASPE members are located in the United States, Canada, Asia, Mexico, South and Central America, the South Pacific, Australia and Europe. They represent an extensive network of experienced engineers, designers, contractors, code officials, manufacturers and manufacturer representatives interested in advancing their careers, their profession and the industry. ASPE is at the forefront of technology. In addition, ASPE represents members and promotes the profession among all segments of the construction industry.

ASPE Chapters All members belong to ASPE worldwide and have the opportunity to belong and participate in one of the 62 state, provincial or local chapters throughout the U.S. and Canada. ASPE chapters provide the major communication links and the first line of services and programs for the individual member. At chapter functions, members can network with others who represent all segments of the plumbing engineering, design, construction and services industry. Chapters produce newsletters, conduct monthly technical meetings and provide opportunities for education, professional development and information sharing to help the membership stay abreast of current trends, code changes and technologies in the plumbing engineering profession.

Membership Communication Communications with the membership is enhanced through the Society's bi-monthly newsletter, the ASPE Report, and the monthly magazine, Plumbing Engineer.

Technical Publications The Society maintains a comprehensive publishing program, spearheaded by the profession's basic reference text, the ASPE Data Book. The Data Book, published in four volumes, encompasses forty-six chapters, provides comprehensive details of the accepted practices and design criteria used in the field of plumbing engineering. The ASPE published library of professional technical manuals and handbooks includes the Domestic Water Heating Design Manual and Model Plumbing Codes: A Comparison Study, the only plumbing engineer's and designer's plumbing code tool of its kind.

Convention and Technical Symposium The Society hosts biennial Conventions on even numbered years and Technical Symposia on odd number years for professional plumbing engineers, designers and contractors to improve their skills, learn original design concepts and make important networking contacts to help them stay abreast of current trends, codes and technologies. In conjunction with each Convention there is the Engineered Plumbing Exposition, the greatest, largest gathering of plumbing engineering and design products, equipment and services. Everything from pipes to pumps to fixtures, from compressor to computers to consulting services is on display to allow engineers and specifiers to view the newest and most innovative design materials available to them. In addition, the Society conducts a number of one- and two-day technical and professional development seminars in conjunction with the Chapters, each year.

Certified in Plumbing Design ASPE sponsors a national certification program for engineers and designers of plumbing systems, which carries the designation "Certified in Plumbing Design" or CPD. The certification program, provides the profession, the plumbing industry, and the general public with a single, comprehensive qualification of professional competence for engineers and designers of plumbing systems. The CPD, designed exclusively by and for plumbing engineers, tests hundreds of engineers and designers at centers throughout the United States biennially. The examination is held in the month of April of even numbered years. Created to provide a single, uniform national credential in the field of engineered plumbing systems, the CPD program is not in any way connected to any state-regulated Professional Engineer (P.E.) registration.

Codes and Legislation The Society maintains liaisons with all plumbing industry and engineering related organizations, as well as providing code and representative liaisons with various federal, state and local governmental agencies and departments. ASPE code and legislative liaisons are members of the coordinating committees for the many organizations promulgating national model codes and, when appropriate, coordinate code and legislative representation at the state and local level.

ASPE Research Foundation The ASPE Research Foundation, established in 1976, is the only independent, impartial organization involved in plumbing engineering and design research. The science of plumbing engineering affects everyone . . . from the quality of our drinking water to the conservation of our water resources to the building codes for plumbing systems . . . our lives are impacted daily by the advances made in plumbing engineering technology through the Foundation's research and development.

In 1973 a group of Engineers and Affiliates decided to form an ASPE Chapter for Northern New Jersey. The first meetings were organized by Andy Ciffer and held at the Travelodge in Somerset, New Jersey. We held our first dinner/dance at the Suburban Hotel in Summit, New Jersey on October 19, 1974. Our Charter was presented to us by then Society President, George Runkle, Jr., P.E.

The Chapter had a total membership of 37 Charter members. Since then, our Chapter membership grew to nearly 200 in the 1990's and has unfortunately slowly dropped to the current 114 members as of May 2010.

Our Chapter has distinguished itself in many ways since it's inception, taking a very active role in the Barrier-Free Movement. With the coming of the Uniform Construction Code in 1976-77, our Chapter was actively involved with the adoption of the National Standard Plumbing Code as the state Plumbing Sub-Code, and continues to this day in the review and adoption of code revisions. Over the years several Chapter members have served on the NSCP Committee as National ASPE Code Representatives.

In 1980, our Chapter assisted the Philadelphia "Delaware Valley" Chapter in re-organizing and starting a chapter newsletter. Other chapter activities with great support of our Affiliates have included conducting Plumbing Inspector License Training Courses, as well as running Continuing Education Seminars for Inspectors and members with PE licenses or CPD certification. Over the past 35 years our Chapter has won many National ASPE Awards. Chapter members have served on many of the National Committees, conducted seminars at the Conventions and Technical Symposiums and have had articles published in the Society Magazines. We have run 5 product shows and 19 consecutive annual golf outings.
