day 1 Flashcards
how much water is delivered by public supply facility
85% of domestic water is delivered by public supply facility
15% supply their own water
watershed
land area that drains water to a particular body of water
public water supply requirements
The systems have at least 15 service connections (houses,businesses, schools) that regularly serve at least 25 individuals daily for at least 60 days out of the year
conveyance loss
water lost in its transit in any way
drainage basin
precipitation runs off into bodys of water
drawdown and artificial recharge
lowering of ground water
artificially adding groundwater
drip irrigation
most efficient form of agriculture
pipes slowly drip water
effluent
water treated from sweage plant
estuary
where fresh and saltwater mix
evaporation
transpiration
evapotranpirastion
evaporation - liquid water turns to vapor
transpiration - water absorbed by plants is evaporated
evapotranspiration- sum of evaporation and transpiration
tributary
small river/stream that flows into larger river/stream
turbidity
how clean/clear the water looks
flood plain
strip of land that is covered by water during a flood
flood stage
elavation at which overflow is measured
giardiasis
cryptosporidium
disease commonly found in dirty water
both with symptoms of diahrea and nausea
confined v unconfined
confined is under pressure significantly different from atmospheric pressure while unconfined is exposed to atmospheric pressure
impermeable layer
layer of material that doesn’t allow water to pass through
infiltration
flow of water from surface to subsurface
leaching
process where soluble material in soil sre washed until lower layer of soil or dissolved
minicipal water system
public water system that has at least 5 sevice connection’s see in 25 individuals for 60 days
point source polution v
non point source polution
point source : solution clearly from one area
non point source: solution over wide area
reverse osmosis
passing water through filter with pressure
outfall
where drainage discharges
grey vs black water
grey: household wastewater that can be recycled on site
black: wastewater with too much organic contents
