Water abstraction

Water abstraction, or water extraction, is the process of taking water from any source, either temporarily or everlastingly. Most water is used for irrigation or treatment to produce drinking water. Depending on the environmental legislation in the relevant country, controls may be located on abstraction to limit the amount of water that can be removed. Over abstraction can lead to rivers drying up or the level of groundwater aquifers reducing unacceptably. The science of hydrogeology is used to assess safe abstraction levels.

Blazer

A blazer or boating jacket is a kind of jacket, generally double-breasted even though single-breasted blazers have become more general in recent times. A blazer looks like a suit jacket except for that it generally has patch pockets with no flaps, and metal shank buttons. A blazer's cloth is usually of a resilient nature as it is used in schools and was used for sport. They frequently form part of the uniform dress of bodies, such as airlines, schools, yacht or rowing clubs, and private security organizations. As sporting dress has become more modified to the activity, the blazer has become limited to clubs' social meetings. Generally, blazers are navy blue, but nearly every colour and mixture of colours has been used, particularly by schools and sporting organizations.
