Yes, artificial intelligence (AI) should be provided to human societies like a commodity or utility. Not unlike water and electricity are provided today to sustain and propel progress, AI will be provided to enhance the quality of human life. Below let's take a look at water, electricity, and AI.
Water
Water is formed by the combination of two atoms of hydrogen with one atom of oxygen (H2O). Water is tasteless, odorless, and nearly colorless liquid at room temperature, with a slight blue tint. Visible water is made up of billions or trillions of molecules, each containing one oxygen atom and two hydrogen atoms held together by strong covalent bonds (sharing of electrons). Water is essential for organic life serving as medium and solvent for the electromagnetic interactions that maintain life.
Water is the most studied chemical compound and is described as the "universal solvent" and the "solvent of life". It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. Water is found on Earth in three different states of matter: gas, solid, and liquid. Water is a polar molecule, meaning that it has ends of opposite polarities. Water interacts best with other polar molecules because their polar opposite charges attract. Although water is the most abundant substance on Earth, it is rarely found naturally in its pure form. Most of the time, pure water has to be created. Pure water is called distilled water or deionized water.
The history of potable water utility spans thousands of years. Access to clean drinking water has been a fundamental aspect of human civilization and has evolved significantly over time. Since water is essential for life, all early human settlements and all major civilizations began close to natural bodies of water such as rivers and lakes. Ever since humans began to figure out ways to handle water storage, handling, and distribution.
Ancient civilizations, such as those in Mesopotamia, Egypt, India, China, Mexico, and Peru developed systems for water supply and distribution. They often relied on wells, aqueducts, and filtration methods to obtain potable water.
Roman Aqueducts: The Romans made remarkable advancements in water supply with their extensive aqueduct systems. These aqueducts transported water from distant sources to cities, providing access to clean water for public baths, fountains, and private residences.
China: Qanats and Canals. Regions in the northwest used qanat systems. Similar to Persian qanats, these were underground channels that tapped into groundwater sources and transported water to agricultural lands and settlements. The Han, Qin, and Tang dynasties constructed elaborate canal systems for irrigation and transportation. The Grand Canal, one of the world's oldest and longest artificial waterways, was built to link the Yellow and Yangtze rivers, facilitating trade and transportation. Dating back to around 256 BC, the Dujiangyan irrigation system in Sichuan Province is a masterpiece of ancient engineering. It utilizes natural terrain to divert water from the Min River to irrigate the Chengdu Plain, without the need for a dam.
India: Stepwells. India is known for its stepwells, intricate structures designed to access groundwater. These wells, like the Rani ki Vav in Gujarat, involved elaborate staircases leading to water sources, allowing access for water extraction, particularly during dry seasons. Traditional water harvesting techniques, such as rooftop rainwater collection and storage in tanks or reservoirs, were common practices across India, supporting agriculture and communities in arid regions.Persia (Iran): Qanats. Persian qanats, also used in parts of China, were underground tunnels or channels that tapped into groundwater sources in arid regions. They provided a reliable and efficient means of accessing water for agriculture and communities.
Southeast Asia: Terraced Rice Fields. In regions like Bali (Indonesia) and the Philippines, terraced rice fields were developed to efficiently manage water for rice cultivation. These fields used a system of terraces to control the flow of water down slopes.
- Inca Empire (South America - primarily Peru): Qanat System. Similar to the qanats found in other parts of the world, the Inca constructed underground aqueducts known as "puquios" to transport water from natural springs to their cities and agricultural areas. These sophisticated systems provided a reliable water supply for irrigation, sanitation, and urban centers like Machu Picchu. Inca engineers used intricate stonework to create channels, canals, and aqueducts made of stone blocks to control water flow and prevent erosion. These structures managed water for agriculture and domestic use.
- Aztec Empire (Central Mexico - primarily around the Valley of Mexico): Chinampas and Raised Fields. The Aztecs developed a system of chinampas—artificial islands or raised fields—in the shallow waters of Lake Texcoco. They used canals and aqueducts to control water levels and supply water to these agricultural plots, enabling efficient farming in a swampy environment. The Aztec capital, Tenochtitlan (present-day Mexico City), had an extensive network of aqueducts and canals that brought freshwater from springs and mountain sources to the city for drinking and bathing purposes. The city's water supply relied on these systems.
- Maya Civilization (Central America - primarily in present-day Mexico, Guatemala, Belize, Honduras): Reservoirs and Cenotes. The Maya constructed reservoirs and collected rainwater in natural sinkholes called cenotes. They also developed sophisticated reservoir systems like the one in the ancient city of Tikal, managing water for agriculture and sustaining large populations. Mayan cities had systems to collect and store rainwater in cisterns, reservoirs, and underground chambers, ensuring a reliable water supply during dry seasons.
Modern Water Treatment: The late 19th and 20th centuries saw significant advancements in water treatment technologies. Filtration, chlorination, and later, more sophisticated methods like ozonation, UV treatment, and membrane filtration, became standard practices in water treatment plants. The establishment of centralized water supply systems became more widespread, especially in urban areas. Water utilities, often operated by municipalities or private companies, were responsible for treating and distributing potable water to households. Governments and international organizations began implementing regulations and standards to ensure the quality and safety of drinking water. Bodies like the World Health Organization (WHO) set guidelines to safeguard public health.
Throughout history, human water management systems have exemplified clever engineering and ingenious solutions to harness water resources for agriculture, urban development, and everyday use. Ancient aqueducts and water management systems were essential for sustaining their populations, supporting agriculture, and facilitating urban development. Many ancient techniques and structures continue to influence modern water management practices. They showcased innovative engineering techniques, adaptation to local environments, and a deep understanding of hydrology and water conservation.
Today, potable water utility involves a combination of advanced technologies, rigorous regulations, and extensive infrastructure to provide clean drinking water to populations worldwide. The focus remains on ensuring access to safe and reliable drinking water while addressing challenges related to water scarcity, pollution, and sustainability. Ongoing technological advancements continue to shape water treatment and distribution. Smart water systems, remote monitoring, more advanced treatment methods, and AI are being employed to improve efficiency, reduce waste, and ensure water safety.
Sewer Systems
Not unlike the history of potable water, the history of sewer lines dates back thousands of years and has evolved significantly over time, reflecting human advancements in sanitation and civil engineering:
Since around 2700 BC, cities like Harappa and Mohenjo-Daro in modern-day Pakistan already showcased sophisticated drainage systems with brick-lined sewers, covered drains, and interconnected channels to handle wastewater disposal and stormwater management.
Antiquity. In ancient Rome, the aqueducts included extensive sewage systems. The Cloaca Maxima, one of the world's oldest known sewer systems, was built around 600 BC in Rome. It carried wastewater away from the city and into the Tiber River. In ancient China, Han Dynasty (206 BC–220 AD) cities such as Chang'an (now Xi'an) had sophisticated drainage systems. These systems included paved streets, stone-lined drains, and covered sewers that carried wastewater away from residential areas. In Japan, ancient cities like Nara and Kyoto had well-planned streets with drainage systems. They utilized stone-lined gutters and covered drains to manage wastewater and rainwater runoff.
In Europe, during the Middle Ages (c. 450 - c. 1450), cities in Europe faced sanitation challenges. Some cities developed simple drainage systems with open trenches or gutters to manage waste, but these were often inadequate.
Mesoamerica. The Aztecs had a system for handling human waste, but no citywide drainage system. The Aztecs built canals and floating gardens in their capital city of Tenochtitlan to manage waste and control flooding. The streets were designed to channel water and waste into the lake. The Aztecs collected human waste and transported it in canoes to be used as fertilizer or sold in the market. The Incas also had a sophisticated system of drainage and sewage management in their cities. The Maya routed streams beneath plazas using aqueduct like structures. The city of Teotihuacan had a sewer system that carried the city's waste outside of the inhabited area.
The 18th and 19th centuries saw rapid urbanization and the rise of industrial cities, leading to increased pollution and sanitation concerns. Public health issues prompted the development of more organized sewer systems. In the mid-19th century, London's sanitation issues, exacerbated by the Great Stink of 1858, led to the construction of a modern sewer system under the direction of engineer Joseph Bazalgette. This system featured large brick sewers that diverted waste away from the Thames River. In Paris, engineer Eugène Belgrand designed an extensive sewer network in the mid-19th century. The Paris sewer system became a model for urban sanitation engineering.
20th century and 21st Century advancements in sewer technologies. Innovations in pipe materials, transitioning from brick and stone to more durable materials like cast iron, vitrified clay, and later, concrete and PVC, improved the durability and efficiency of sewer systems. Modern sewer systems are not just about waste disposal but also include wastewater treatment facilities. Sewage treatment plants became integral in removing pollutants and contaminants from wastewater before its discharge into water bodies. Sewer systems also handle stormwater runoff, with separate systems for wastewater and stormwater in many cities to prevent overload during heavy rainfall. Some cities are implementing smart technologies and using AI to monitor and manage sewer systems in real-time, detecting issues like blockages or leaks and optimizing maintenance.
Throughout ancient times, various human civilizations employed engineering techniques to develop sewer systems that managed waste and promoted public health. These systems demonstrated sophisticated urban planning and engineering prowess, considering factors like drainage, sanitation, and efficient water management. The evolution of sewer lines reflects the continuous efforts to improve public health, manage waste, and protect the environment. Today's sewer systems are a testament to centuries of engineering advancements aimed at providing efficient and environmentally responsible waste management solutions for urban areas.
Modern Wastewater Treatment Plants
Wastewater treatment plants (WWTPs) play a crucial role in cleaning and purifying wastewater before it's released back into the environment. These facilities use various physical, chemical, and biological processes to remove contaminants and pollutants from sewage or wastewater.
1. Preliminary Treatment:
- Screening. Incoming wastewater passes through screens or bar racks to remove large objects like sticks, rags, plastic, and debris. This prevents damage to downstream equipment.
- Grit Removal. After screening, wastewater goes through a grit chamber to remove sand, gravel, and other heavy particles that settle at the bottom.
2. Primary Treatment:
- Sedimentation. The wastewater moves to a sedimentation tank where it's held for a period, allowing solids to settle. This process separates suspended solids (sludge) that sink to the bottom from the liquid (effluent) at the top. The separated sludge is removed for further treatment (anaerobic digestion, incineration, or drying) to reduce its volume and stabilize it for disposal.
3. Secondary Treatment (Biological Treatment):
- Aeration (Activated Sludge Process). Effluent from the primary treatment undergoes biological treatment. It's mixed with air and microorganisms (activated sludge) in aeration tanks. Bacteria break down organic matter into carbon dioxide, water, and more sludge.
- Clarification. The mixed liquor from the aeration tanks goes to settling tanks, allowing the activated sludge to settle at the bottom and separate from the treated water (effluent).
- Secondary Clarification and Sludge Processing. The clarified effluent is discharged or subjected to further treatment if necessary. Part of the settled sludge is returned to the aeration tanks to maintain the microbial population, while excess sludge is removed for further treatment or disposal.
4. Tertiary Treatment (Optional):
- Additional Filtration or Disinfection. Some WWTPs have additional treatment steps like sand filtration, membrane filtration, or disinfection (chlorination, UV treatment) to further remove remaining pollutants or pathogens from the effluent before discharge.
5. Discharge or Reuse:
- Effluent Discharge. The treated effluent is discharged into receiving water bodies (rivers, streams, or oceans) following local environmental regulations and standards.
- Water Reuse. In some cases, treated wastewater is further purified for reuse in irrigation, industrial processes, or even as potable (drinking) water in water-stressed regions (advanced treatment like reverse osmosis may be required for this purpose).
Modern wastewater treatment plants employ multiple processes to remove contaminants, reduce pollution, and protect the environment, ensuring that discharged water meets regulatory standards and is safe for the ecosystem it enters.
Water Utility Companies
Water utilities play a vital role in collecting, treating, and distributing water to consumers. Here's an overview of how water utilities typically operate:
1. Water Collection:
Water utilities obtain water from various sources such as rivers, lakes, reservoirs, groundwater wells, or sometimes desalination plants for coastal regions. Water is collected from these sources and transported to water treatment plants through pipes, canals, or aqueducts.
2. Water Treatment:
As discussed above, at treatment plants, water undergoes various processes including: screening and Filtration to remove large debris; coagulation and flocculation (adding chemicals to clump together fine particles); sedimentation and filtration (settling of particles and further filtration to remove impurities); disinfection (adding chlorine or other disinfectants to kill pathogens); pH adjustment and chemical to ensure water meets quality standards.
3. Water Distribution:
Treated water is stored in reservoirs or tanks to ensure a constant supply during peak demand periods and emergencies. Water is distributed through an extensive network of underground pipes and distribution mains. These pipes vary in size and transport water to neighborhoods, homes, and businesses. Pressure is regulated through pumps and valves to ensure consistent water flow and adequate pressure throughout the distribution network.
4. Billing and Customer Service:
- Water utilities install water meters at consumers' premises to measure water usage accurately. Water utility companies bill consumers for their water usage based on meter readings and local pricing structures. Billing typically covers the cost of water treatment, distribution, maintenance, and operational expenses.Water utilities provide customer service for inquiries, complaints, meter readings, and assistance with water-related issues.
5. Water Conservation and Regulation:
- Utilities often promote water conservation programs and initiatives to encourage consumers to use water efficiently. Water utilities must adhere to local, state, and federal regulations regarding water quality, safety, and environmental standards.
6. Water Quality Monitoring and Maintenance:
- Water utilities regularly monitor water quality at various stages to ensure it meets health and safety standards. Ongoing maintenance and repair of water infrastructure, such as pipes and treatment facilities, are crucial to ensure reliable service.
Water utilities operate as regulated entities responsible for providing safe, clean, and reliable water to consumers while adhering to environmental and safety standards. Their operations encompass a range of functions, from sourcing water, treating it for distribution, distributing it, metering consumption, billing, providing quality control, and maintaining infrastructure.
