21. Study the drinking water supply system in your area. What is the source of drinking water, where water is purified and how it gets distributed in the locality. Study what happens to the waste water drainage brief.
Answers
Answer:
The first municipal water utility in the United States was established in Boston in 1652 to provide domestic water and fire protection (Hanke, 1972). The Boston system emulated ancient Roman water supply systems in that it was multipurpose in nature. Many water supplies in the United States were subsequently constructed in cities primarily for the suppression of fires, but most have been adapted to serve commercial and residential properties with water. By 1860, there were 136 water systems in the United States, and most of these systems supplied water from springs low in turbidity and relatively free from pollution (Baker, 1948). However, by the end of the nineteenth century waterborne disease had become recognized as a serious problem in industrialized river valleys. This led to the more routine treatment of water prior to its distribution to consumers. Water treatment enabled a decline in the typhoid death rate in Pittsburgh, PA from 158 deaths per 100,000 in the 1880s to 5 per 100,000 in 1935 (Fujiwara et al., 1995). Similarly, both typhoid case and death rates for the City of Cincinnati declined more than tenfold during the period 1898 to 1928 due to the use of sand filtration, disinfection via chlorination, and the application of drinking water standards (Clark et al., 1984). It is without a doubt that water treatment in the United States has proven to be a major contributor to ensuring the nation’s public health.
Answer: this answer is a general overview to the question.
The source of drinking water can vary depending on the location. It can come from surface water sources such as rivers and lakes or from groundwater sources such as wells.
The water is then transported to a treatment facility where it is purified.
The purified water is then distributed to the local residents through a network of pipes. The distribution system can include pumping stations, storage tanks, and other equipment to ensure that the water is delivered under the appropriate pressure and at the correct volume.
Regarding the waste water drainage, it goes through a process called "wastewater treatment"
Explanation:
- The source of drinking water can vary depending on the location. It can come from surface water sources such as rivers and lakes or from groundwater sources such as wells.
- The water is then typically transported to a treatment facility where it is purified through a series of processes such as sedimentation, filtration, and disinfection etc
- The purified water is then distributed to the local residents through a network of pipes. The distribution system can include pumping stations, storage tanks, and other equipment to ensure that the water is delivered under the appropriate pressure and at the correct volume.
- Regarding the waste water drainage, it goes through a process called "wastewater treatment" where it is cleaned and treated before it is discharged back into the environment or reused. This process includes several stages, such as primary treatment, secondary treatment, and tertiary treatment. The primary treatment is the physical separation of solids and liquids, while the secondary treatment removes the dissolved and suspended biological matter. Tertiary treatment is a final process of polishing the effluent before it is discharged or reused.
