What is difference between tap water and drinking water?
Tap Water- provide quality water for human consumption and other uses (e.g., washing clothes, bathing, and industrial and commercial uses) through a piped distribution system to specific communities. Public water systems are granted exclusive rights to provide water to consumers in a particular geographic or municipal area. Consumers do not, therefore, have a choice of which public water system will provide water to their homes or businesses. Drinking Water- Drinking water considered fit for human consumption comes from many sources, all of which must comply with the safety standards outlined by the U.S. Environmental Protection Agency.

obviously depending on the region. In urope the words are used synonymously, as all tap water has drinking water quality except is few rare cases of mismanagment.

Tap water:- This is water that is delivered to the point of demand through a network of pipeline. Usually, it is expected to be safe for human consumption and other domestic demand. The water may be clean at it source like ground water, while some time it may require quality improvement through it treatment, example water from the lake, Dams or rivers. There are different types of water treatment methods. Drinking water is the water that is safe for human consumption. It satisfy WHO drinking water quality standard or other drinking water standard as may be relevant.

Dear Abdulwahed, For simplicity, the tap water is potable water delivered directly to the user (households, businesses, public buildings, etc.). It is transported by a pipeline network from its collection point (source, drilling, river, etc.) to users of taps. Most often, this water is made potable by a treatment center and disinfection, and then stored in one or more reservoirs (eg water tower) waiting to be consumed. The quality of tap water is highly regulated and subject to numerous health checks, in developed countries. It most often comes from a groundwater, river, or simply an apparent source and undergoes numerous treatments before reaching the consumer. In some areas, it comes from desalination. Water is pumped or gravity fed naturally from its collection point (well, river, source) to the treatment plant. When it comes to pumping in the river, the water intake is usually protected by a large grid to prevent the intrusion of large objects in the pipeline. Water first passes into a decanter where it will spend more or less time depending on its condition. The heavier suspended materials settle to the bottom of the decanter. To accelerate settling and improve its efficiency of flocculants and / or coagulants are sometimes added to water, it is most often ferric or aluminum chloride. These flocculants and coagulants products will enable small suspended solids to agglomerate and form a mass which will come off more easily. The solids settle to the bottom of the settling tank. Thereafter, water is removed at the surface of the decanter and freed from the bulk of impurities. Note: When water is pumped from a deep aquifer, it may happen that it is particularly clean and therefore has no need to undergo a stage of settling / flocculation / coagulation. This water therefore directly suffer the disinfection step. The water may then be filtered through a sand filter. Sand layers retain suspended particles which do not remain in the separator, but also pests. The clarified water comes out and is ready to be disinfected. The disinfection step can be done in different ways, with ozone or chlorine. These very oxidants will attack the bacteria and viruses to make them harmless. Ozone is a gas which does not carry and therefore must be generated on site by an ozonizer. The cost of production of ozone explains why ozonation exists only in large treatment plants. Water can then pass through an activated carbon filtration step beans. Activated carbon holds chemical or organic substances which remain in the water, no pesticides. The final step consists of an addition of chlorine into the water to ensure that water will be disinfected well until it reaches the consumer's tap. Drinking water is pumped and sent in tanks in height (from water tower type) waiting to be consumed by users who need only to open their taps to access their water. Generally, the tanks are filled or continuously every day with a newly produced water. With my best regards Prof. Bachir ACHOUR

Dear Abdulwahed Ahmadi, Maybe the following may be of your interest, altough there is some redundancy with the earlier feedback, Drinking water (also known as potable water) meets regulatory drinking water quality standards and is safe for drinking and food preparation. Typically in developed countries, tap water meets drinking water quality standards, indicating that tap water is drinking water. Tap water is drinking water transported through a distribution network. Both the network and water quality during dirstibution are monitored to make sure the water is safe. Usually a very small portion of tap water is used for drinking and food preparation. Most is used for washing and toilet. Bottled water is drinking water in bottles. In 2001 a WWF study, "Bottled water: understanding a social phenomenon", warned that in many countries, bottled water may be no safer or healthier than tap water and it sold for up to 1,000 times the price of tap water. It said the booming market would put severe pressure on recycling plastics and could lead to landfill sites drowning in mountains of plastic bottles (Wikipedia, bottled water). Also, the WWF study discovered that the production of bottled water uses more water than the consumer actually buys in the bottle itself. Best regards, Hans

In simple words and being redundant: Tap water is distributed by municipal pipelines, it can be used for washing clothes or dishes, showering, irrigating, etc. As mentioned above it comes either from underground or nearby surface sources; however the treatments may vary according to both: quality it has from the source and the quality and parameters that must meet according to local or national regulations. In some cases (mostly when it comes from underground sources and depending on the geology of the land) you get tap water that has heavy metals or flouride; so this is tap water but NOT drinkable water. Processes involved may consist of settling, coagulation-floculation, filtering, reverse osmosis, desinfection (either using UV, ozone or chlorine). Also, for labelling water as "drinkable" it must be considered flavor and odor; but this is something very tricky since this are organoleptic parameters. Cheers

Dear Mr. Ahmadi, In fact, there is a great confusion when dealing with all these terms: tap water, drinking water, crude water, potable water, treated water... To simplify the problem, consider that drinking water is the water whose parameters meet the drinking water standards fixed for your region. Usually it is also potable water, which is a water that can be consumed by humans without risks to their health. But (this may appear strange!) a potable water may not be a drinking water! For example: brazilian legislation states that you can not distribute any water for public consumption if it has not been disinfected (at least) whith a disinfectant agent with residual effect, such as chlorine, although it is potable in the manantial. The intention is to assure that if some contamination happens in the distribution system, there will be a disinfectant in the water to assure its potability. So, a crude water (which is a water in the form that is found in the nature) may be potable without being a drinking water, from the point of view of the law! Also, a treated water may not be a potable water if the treatment was insufficient for this purpose (which is obvious!). Tap water is a water from a tap. What are you going to do with this water? Irrigation? Laundry? Drink? So, there may be great difference between drinking water, tap water, potable water and other clasifications, as you can see! Did I help you? Yours, Marcos

I agree with all the previous explanations about tap,crude,and drinking water.With de-sal water there maybe low PPB levels of ions normally found in salt water,depending on the length of treatment,shape of the RO filters, and maintenance of the system used.

Drinking water means the water in which physical, chemical and bacteriological parameters are within the permissible limits of drinking water. If tap water has this quality can be considered as drinking water. Thus source of water or how it is supplied is not important.

I agree with all the previous comments, which summarized, state: -tap water is delivered by piping to the consumer; if the consumer drinks it, it is also drinking water. -drinking water should meet all regulatory standards for the country in which it is consumed. I would add that there are other sources of drinking water that have not been mentioned. These include bottled water, both individual bottles and delivered larger containers. Individual or small groundwater wells can be drinking water and/or tap water; consider individual wells that provide drinking water (either at a tap or from the well) and which are usually not treated with disinfectants and too small to be regulated.
