Water and Sanitation

Standards March: Water

Water is essential for sanitation and hygiene — and proper sanitation is essential for protecting water sources from contamination and ensuring access to safe drinking water.  Access to safe water and sanitation is crucial for preventing the spread of waterborne diseases, which can be transmitted through contaminated water sources or poor sanitation practices. Lack of access to safe water and sanitation can lead to a range of health problems, including diarrheal diseases, cholera, typhoid, and hepatitis A.  

On the other hand, poor sanitation practices, such as open defecation, can contaminate water sources, making them unsafe for drinking, bathing, or cooking. This contamination can lead to the spread of diseases and illness, particularly in developing countries where access to clean water and sanitation facilities may be limited.

We track the catalog of the following ANSI accredited standards developers that necessarily require mastery of building premise water systems:

American Society of Heating, Refrigerating and Air-Conditioning Engineers: ASHRAE develops standards related to heating, ventilation, air conditioning, refrigeration systems — and more recently, standards that claim jurisdiction over building sites.

American Society of Mechanical Engineers: ASME develops standards related to boilers, pressure vessels, and piping systems.

American Water Works Association: AWWA is a standards development organization that publishes a wide range of standards related to water supply, treatment, distribution, and storage.

ASTM International: ASTM develops and publishes voluntary consensus standards for various industries, including water-related standards. They cover topics such as water quality, water sampling, and water treatment.

National Fire Protection Association: NFPA develops fire safety standards, and some of their standards are related to water, such as those covering fire sprinkler systems and water supplies for firefighting within and outside buildings.  We deal with the specific problems of sprinkler water system safety during our Prometheus colloquia.

National Sanitation Foundation International (NSF International): NSF International develops standards and conducts testing and certification for various products related to public health and safety, including standards for water treatment systems and products.

Underwriters Laboratories (UL): UL is a safety consulting and certification company that develops standards for various industries. They have standards related to water treatment systems, plumbing products, and fire protection systems.

United States Standards System


* The evolution of building interior water systems has undergone significant changes over time to meet the evolving needs of society. Initially, water systems were rudimentary, primarily consisting of manually operated pumps and gravity-fed distribution systems. Water was manually fetched from wells or nearby sources, and indoor plumbing was virtually nonexistent.

The Industrial Revolution brought advancements in plumbing technology. The introduction of pressurized water systems and cast-iron pipes allowed for the centralized distribution of water within buildings. Separate pipes for hot and cold water became common, enabling more convenient access to water for various purposes. Additionally, the development of flush toilets and sewage systems improved sanitation and hygiene standards.

In the mid-20th century, the advent of plastic pipes, such as PVC (polyvinyl chloride) and CPVC (chlorinated polyvinyl chloride), revolutionized plumbing systems. These pipes offered durability, flexibility, and ease of installation, allowing for faster and more cost-effective construction.

The latter part of the 20th century witnessed a growing focus on water conservation and environmental sustainability. Low-flow fixtures, such as toilets, faucets, and showerheads, were introduced to reduce water consumption without compromising functionality. Greywater recycling systems emerged, allowing the reuse of water from sinks, showers, and laundry for non-potable purposes like irrigation.

With the advancement of digital technology, smart water systems have emerged in recent years. These systems integrate sensors, meters, and automated controls to monitor and manage water usage, detect leaks, and optimize water distribution within buildings. Smart technologies provide real-time data, enabling better water management, energy efficiency, and cost savings.

The future of building interior water systems is likely to focus on further improving efficiency, sustainability, and water quality. Innovations may include enhanced water purification techniques, decentralized water treatment systems, and increased integration of smart technologies to create more intelligent and sustainable water systems.

The first mover in building interior water supply systems can be traced back to the ancient civilizations of Mesopotamia, Egypt, and the Indus Valley. However, one of the earliest known examples of sophisticated indoor plumbing systems can be attributed to the ancient Romans.

The Romans were pioneers in constructing elaborate water supply and distribution networks within their cities. They developed aqueducts to transport water from distant sources to urban centers, allowing for a centralized water supply. The water was then distributed through a network of lead or clay pipes to public fountains, baths, and private residences.

One notable example of Roman plumbing ingenuity is the city of Pompeii, which was buried by the eruption of Mount Vesuvius in 79 AD. The excavation of Pompeii revealed a well-preserved plumbing system that included indoor plumbing in some houses. These systems featured piped water, private bathrooms with flushing toilets, and even hot and cold water systems.

The Romans also invented the concept of the cloaca maxima, an ancient sewer system that collected and transported wastewater away from the city to nearby bodies of water. This early recognition of the importance of sanitation and wastewater management was a significant advancement in public health.

While the Romans were not the only ancient civilization to develop indoor plumbing systems, their engineering prowess and widespread implementation of water supply and sanitation infrastructure make them a key player in the history of building interior water systems.

Backflow

The University has a strong reputation for research and innovation in many fields related to the prevention of backflow incidents:

Viterbi School of Engineering has a dedicated Environmental Engineering program that focuses on water quality and management. This program has faculty members who are experts in water treatment and distribution systems, including backflow prevention technologies. The school also offers research opportunities for graduate students to work on water-related projects, including those related to backflow prevention.

Keck School of Medicine has a Department of Preventive Medicine that conducts research on environmental health, including waterborne diseases and contamination. This department has published research on the prevention of waterborne disease outbreaks and the importance of backflow prevention measures in protecting public health.

The USC Environmental Health and Safety department is responsible for overseeing the safety and compliance of the university’s facilities, including its water systems. EH&S works closely with the university’s Facilities Management Services to ensure that backflow prevention measures are in place and maintained.

The USC Foundation drafts definitions and specifications covering cross-connection control and the assemblies required for the prevention of backflow.

Hospital and research labs generate complex effluents containing hazardous chemicals, pharmaceuticals, cytotoxic drugs, radioactive isotopes, pathogens, and heavy metals. When discharged untreated into municipal sewers, these substances can:

  • Disrupt biological treatment processes by killing beneficial microbes in wastewater plants
  • Pass through treatment systems into rivers and drinking water sources
  • React with other wastes, forming new toxic compounds
  • Violate environmental regulations and expose institutions to fines

Dedicated collection, pretreatment, and specialized disposal systems allow safe neutralization or destruction of these wastes. This protects aquatic ecosystems, prevents the spread of antibiotic resistance, safeguards community water supplies, and fulfills the ethical responsibility of research institutions to minimize environmental harm.

When the wicked problems of peace and economic inequality cannot be solved, political leaders, and the battalions of servile administrative muckety-mucks who report to them, resort to fear-mongering about an imagined problem to be solved centuries hence assuming every other nation agrees on remedies of its anthropogenic origin.  We would not draw attention to it were it not that large tranches of the global academic community are in on the grift costing hundreds of billions in square-footage for research and teaching hopelessness to our children and hatred of climate change deniers.

Before the internet is scrubbed of information contrary to climate change mania, we recommend a few titles:

Agreement on academic credentials is vital to the United States’ higher education export industry, one of America’s largest service exports.  In 2023–24, international students contributed approximately $45–50 billion to the U.S. economy through tuition, living expenses, and related spending. For this industry to thrive, foreign students must have confidence that their home-country qualifications will be fairly evaluated for admission, while U.S. degrees must be widely recognized abroad for further study or employment. 

 

Clear credential recognition agreements reduce barriers, streamline admissions, and build trust. They encourage more students to choose U.S. universities over competitors in the UK, Australia, or Canada. Without such agreements, bureaucratic obstacles, lengthy evaluations, and uncertainty deter students, directly threatening university revenue, campus diversity, and the economic impact of this major export sector.

Accreditation 200: Recent innovations in credentialing

Q. There are about 150 hospitals in the USA with the word “university” in their name.  Are they tax-exempt?  Should they be?  A.  Whether a hospital with “university” in its name is tax-exempt depends on various factors, including its ownership, structure, and purpose. Non-profit hospitals, including those affiliated with universities, may qualify for tax-exempt status under certain conditions. However, the mere presence of “university” in the name does not automatically confer tax-exempt status.  Tax-exempt status, the hospital’s activities, such as providing charity care, medical education, and research, are typically considered.
