Final answer:
Devices that discharge clear wastewater into the building drainage system, such as water lifts and expansion tanks, should be installed by a licensed plumber. Engineers with specialties in mechanical and construction engineering are crucial for the maintenance and construction of water treatment plants, ensuring the distribution of potable water and the functionality of systems that require clean and non-contaminated water, like cooling towers in power plants.
Step-by-step explanation:
Water lifts, expansion tanks, cooling jackets, sprinkler systems, drip or overflow pans, and similar devices that discharge clear wastewater into the building drainage system should be installed by a licensed plumber. This requirement ensures that installations comply with local codes and standards, which are designed to maintain safety and functionality. Chemical drain cleaners used by plumbers can vary in form; for example, alkaline cleaners come in both solid or liquid states, while acidic cleaners are typically found in liquid form. When it comes to plumbing systems, air-filled tubes near water faucets, also known as air chambers, are used to prevent water hammer by cushioning the sudden stoppage of water flow, thereby reducing the stress on plumbing joints and fixtures.
Maintenance and construction of water treatment plants, which include removing harmful materials and ensuring water quality, involve the expertise of several engineering specializations such as mechanical engineering and construction engineering. These professionals are also responsible for managing the intricate processes that bring safe and clean water to our homes and facilities. It's crucial to note that different water systems in facilities, like those in a nuclear power plant, are kept separate to prevent mixing between nonradioactive and radioactive areas, ensuring safety and environmental protection. Additionally, features like cooling towers often use evaporative cooling, which is visible as a plume of water vapor, but this should not be mistaken for exhaust emissions.
