This supply may come from several possible sources. 1. Municipal water supply 2. Water wells 3. Delivered by truck 4. Processed water from creeks, streams, rivers, lakes, rainwater, etc.

HYDRAULICS OF FLOW IN PIPES

TAP WATER

 

Tap water (running water, city water, municipal water, etc.) is a principal component of "indoor plumbing", which became available in urban areas of the developed world during the last quarter of the 19th century, and common during the mid-20th century. The application of technologies involved in providing clean or "potable" water to homes, businesses and public buildings is a major subfield of sanitary engineering.

 

Potable water supply

 

This supply may come from several possible sources.

 

1.     Municipal water supply

2.     Water wells

3.     Delivered by truck

4.     Processed water from creeks, streams, rivers, lakes, rainwater, etc.

 

Domestic water systems have been evolving since people first located their homes near a running water supply, e.g., a stream or river. The water flow also allowed sending waste water away from the domiciles.

 

Modern indoor plumbing delivers clean, safe, potable water to each service point in the distribution system. It is imperative that the clean water not be contaminated by the waste water (disposal) side of the process system. Historically, this contamination of drinking water has been the largest killer of humans.

Hot water supply

 

Domestic hot water is provided by means of water heater appliances, or through district heating. The hot water from these units is then piped to the various fixtures and appliances that require hot water, such as lavatories, sinks, bathtubs, showers, washing machines, and dishwashers.

 

Fixtures and appliances

 

Everything in a building that uses water falls under one of two categories; Fixture or Appliance. As the consumption points above perform their function, most produce waste/sewage components that will require removal by the waste/sewage side of the system. The minimum is an air gap. See cross connection control & backflow prevention for an overview of backflow prevention methods and devices currently in use, both through the use of mechanical and physical principles.

 

 

Fixtures are devices that use water without an additional source of power.
