ANN ARBOR, Mich. and DES PLAINES, Ill. — NSF International and the American Society of Plumbing Engineers have signed a Memorandum of Understanding (MOU) to advance and promote public health and sustainability initiatives within the plumbing industry. The MOU impacts the design, specifications, installation, inspection and regulation of plumbing systems.

NSF International is an independent global organization that writes public health standards and protocols, and tests and certifies products for the water, food and consumer goods industries. This includes developing multiple American National Standards and certifying a wide range of plumbing and water treatment products.  Products bearing the NSF Mark demonstrate compliance with national standards and utilize innovative water treatment technologies. 

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.

Under the MOU, NSF International and ASPE will write standards that benefit public health and the environment by supporting each other’s missions: to advance the science of plumbing engineering and human health. This will be accomplished by jointly developing educational resources in addition to promoting conferences and publications that highlight water quality and conservation.

“Over the years, NSF International has earned high marks for credibility in serving the needs of public health and safety,” says ASPE Executive Director/CEO Jim Kendzel, MPH. “NSF is at the cutting edge of providing conformity assessment programs that serve the current and future needs of the plumbing industry, and ASPE is proud to join with NSF to help meet those needs and ensure that safer, more efficient water and wastewater delivery and treatment systems are used worldwide.”

“Together ASPE and NSF International have the expertise and knowledge to promote and educate others about the importance of innovation and sustainability within the plumbing industry.  I look forward to the opportunities that our partnership will provide to further advance and protect public health on a global scale,” said Nasrin Kashefi, General Manager of NSF International’s Plumbing Program.

About NSF International: NSF International is an independent organization that writes standards, tests and certifies products for the food, water and consumer goods industries to minimize adverse health effects and protect the environment (  Founded in 1944, NSF is committed to protecting human health and safety worldwide.  NSF is a World Health Organization Collaborating Centre for Food and Water Safety and Indoor Environment.

NSF International's Water Programs require extensive product testing and unannounced audits of production facilities to verify that water treatment products meet the design, material and performance requirements.  NSF International is accredited by the American National Standards Institute (ANSI).

NSF led the development of the American National Standards for all materials and products that treat or come in contact with drinking water.  In 1990, the U.S. EPA replaced its own drinking water product advisory program with these NSF standards.  Today, all major plumbing codes require certification to NSF standards for pipes and plumbing components in commercial and residential buildings.

About The American Society of Plumbing Engineers (ASPE): Founded in 1964, ASPE is the only professional organization devoted to the training and certification of plumbing engineers and designers. ASPE and its 6,200 worldwide members are dedicated to protecting the health, welfare, and safety of the public through the dissemination of technical data and information to expand the base of knowledge among plumbing engineers, designers, contractors, code officials, inspectors, and manufacturers.
