An interesting feature of the Dutch water sector is a performance benchmarking system for water companies first introduced in 1997, which has inspired similar efforts in other European countries. The Dutch parliament passed a law in 2004 banning private sector provision of water supply.
Water is also central to acid-base neutrality and enzyme function. An acid, a hydrogen ion (H +, that is, a proton) donor, can be neutralized by a base, a proton acceptor such as a hydroxide ion (OH −) to form water. Water is considered to be neutral, with a pH (the negative log of the hydrogen ion concentration) of 7 in an ideal state.
The term "water board" or "regional water authority" may be confusing in the Dutch context, as water boards and regional water authorities in other countries are often responsible for water supply. A waterschap or hoogheemraadschap in the Netherlands is charged with the control and management of water as well as treatment of waste water, but ...
Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. [26] Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color.

Water covers about 71% of the Earth's surface, with seas and oceans making up most of the water volume (about 96.5%). Small portions of water occur as groundwater (1.7%), in the glaciers and the ice caps of Antarctica and Greenland (1.7%), and in the air as vapor, clouds (consisting of ice and liquid water suspended in air), and precipitation ...
The term is derived from the Middle Dutch kille (kil in modern Dutch), meaning "riverbed" or "water channel". [1] It is found in areas of Dutch influence in the Netherlands' former North American colony of New Netherland, primarily the Hudson and Delaware Valleys. Examples of the freestanding use of "kill" are:
