Water consumption
The portion consumed upon usage, which is not expelled as cooling water or sewage water and instead remains in the product or evaporates.
Water cycle
The chronological sequence of location and state changes of water.
Water pollution
Pollution of bodies of water due to introduction of communal and industrial waste water, also due to solid substances being washed out.
Water requirement
The requirement for drinking water as well as the water required by businesses and industries Industrial water.
Water reserve
Part of a drinking water catchment area, in which usage limitations are imposed to protect the (ground) water; it is usually subdivided into smaller and
larger protected zones.
Water resources
The quantitative measurement of water circulation (water balance) and the regulation of this; important part of Water supply and distribution. The
biochemical reactions and therefore all life processes are carried out in the cell in the aqueous phase. In its role as a solvent and transport agent for
metabolic products and carrier material of living organisms, the portion of water in protoplasm is usually 60 to 80%. Disturbances in the water resource
have a direct impact on life activities, and dehydration of 10 to 15% is fatal for vertebrates.
Water Resources Act
Abbreviation: WRA. The water resources act contains regulations for maintaining proper water resources, e.g. groundwater usage and sewage water
regulation. The water resources act is enforced by the water authorities together with technically specialized agencies (See: Water board).
Water supply
All measures for procurement, treatment, storage, delivery and distribution of drinking water and industrial water. Ground water can be suitable as
drinking water, whereas seeping water and rain water have to be filtered and treated. River water can only be used once it has been cleaned and treated,
despite rivers' self-cleaning properties. In the waterworks, the water is entered into a cleaning system with coarse and fine filters. The degree to which
water is cleaned by filtration is sufficient mechanically but not biologically. Water is usually disinfected by adding chlorine; newer procedures even
accomplish this without compromising the taste of the water. Other disinfection procedures use ultraviolet radiation or the addition of ozone (ozonizing).
The purified water is collected in large underground tanks (concrete peristyles) with a water depth of several meters or in water towers and released into
the delivery pipe and transported to the consumers on demand.
Water supply and distribution
All measures pertaining to regulating and maintaining water resources.
Water-based paints
Better: water-dilutable paints. Paint systems in which organic solvents are either completely or largely replaced by water as the solvent. Especially
effective with base coat paints for two-coat systems.
Watt
Unit for power: W. Energy flow rate or heat flow rate; 1 W = 1 Joule per second.
WHO
Abbreviation for World Health Organization. It was founded in 1948 as an independent organization of the UN with its headquarters in Geneva and with
regional branch offices around the world. The WHO only has a consulting and coordinating function.
Working materials ordinance
The ordinance on hazardous working materials dated 11 February 1982 governs the introduction and handling of hazardous working materials and also
covers monitoring the health of employees who handle hazardous substances. It was superseded on 1 October 1986 by the Hazardous substance
