Metro Vancouver Watersheds

They provide tap water to a land area covering more than , serving a total of 21 member municipalities, one electoral district, and one treaty First Nation. From west to east, the watersheds are the Capilano (), the Seymour (), and the Coquitlam (). They are located in the North Shore Mountains and Coquitlam Mountain, respectively. Each watershed possesses a reservoir for water storage purposes, under the control of Metro Vancouver. The reservoirs are supplied by about of rain and of snowpack annually. Two additional off- catchment areas (Lower Seymour Conservation Reserve and Or Creek watershed) under control of Metro Vancouver contribute to the water supply.http://www.bctwa.org/AboutGreaterVanWatersheds.pdf The watersheds have a long history of controversies surrounding logging, highway develop ...

Drinking Water
Drinking water or potable water is water that is safe for ingestion, either when drunk directly in liquid form or consumed indirectly through food preparation. It is often (but not always) supplied through taps, in which case it is also called tap water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. For those who work in a hot climate, up to a day may be required. About 1 to 2 billion people lack safe drinking water. Water can carry vectors of disease and is a major cause of death and illness worldwide. Developing countries are most affected by unsafe drinking water. Sources Potable water is available in almost all populated areas of the world, although it may be expensive, and the supply may not always be sustainable. Sources where drinking water is commo ...

Surface Runoff
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to ''channel runoff'' (or ''stream flow''). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is #Saturation excess overland flow, saturated by water to its full capacity, and the rain arrives #Infiltration excess overland flow, more quickly than the soil can absorb it. Surface runoff often occurs because wikt:impervious#Adjective, impervious areas (such as roofs and Road surface, pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of Soil erosion#Rainfall and runoff, soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. ...
