Tap Water

Tap water is water that is supplied through a water dispenser valve and is derived from a public water system. Public water systems (PWSs) are municipal bodies that are responsible for regulating, operating, and maintaining treatment plants or water sources that supply drinking water distribution systems. The development and spread of tap water systems over the past century has transformed the world by making clean water available to billions of people who would otherwise have continued to suffer all the health and development problems caused by clean water scarcity of centuries past.

The main advantage of tap water throughout the world is its low cost. Tap water costs a fraction of a penny per gallon. According to the Harvard Energy and Facilities department, tap water is 3000% less expensive per gallon than bottled water, at $0.02 per gallon to $0.64 per gallon of bottled water.

The main disadvantage of tap water is the requirement of well-developed infrastructure for ensuring its adequate regulation, maintenance, and contamination prevention. The maintenance of a safe tap water system requires a well-oiled regulatory organization that sets and enforces standards. Unfortunately, the governmental infrastructure for this type of organization is weak in many developing countries which partly explains why there is a lack of access to safe tap water in many developing countries. This video from PBS NewsHour examines the problems Cape Town, South Africa has faced maintaining adequate water infrastructure.

Furthermore, tap water is more exposed to contamination. The sources of public water systems are often surface waters such as rivers, lakes, or reservoirs that are fed through tributaries. These surface waters can be exposed to significant environmental pollution which bottled water generally has less exposure to. A household water treatment device (UVC WATER PURIFIER) is needed under the circumstances.

Additionally, the pipe networks that are the foundation of tap water systems are often old or otherwise at risk of intrusion of contaminants. For example, environmental and sewage intrusion from the outside of the pipe to the inside as well as heavy metals leaking from old copper pipes can all cause contamination of tap water.
