Ventilation and storm drainage system

ventilation

means of removing air by natural or artificial methods

vent

a pipe that conveys air to or from a drainage system

vent system

a system of pipes or openings used for ensuring the circulation of air

vent pipe

a pipe attached to a drainage pipe or trap

vent or main stack

vertical vent pipe for circulating air

stack vent/soil vent/waste vent

extension to open air of a soil or waste stack above the horizontal branch drain or fixture

back vent

vent that connects to a single fixture trap

circuit vent

branch vent that serves two or more traps

dual vent

a vent that connects to dual fixture traps

yoke vent

pipe connecting upward from a soil or waste stack

wet vent

double purpose vent that serves both a fixture branch and vent

fixture vent

vent pipe that leads from a drainage pipe to another vent pipe

branch vent

a vent connecting one or more individual vent stack

ejector vent

a pipe used to provide air in a sump pit and prevent pressure buildup

Storm Drainage System

a component system that conveys rainwater from a building or site to points of disposal

roof drain

a device fixed on the roof that receives water collected on the surface of the roof

gutter

A channel of metal, wood, or concrete set below and along the eaves of a building to catch and carry off rainwater from the roof

leader

horizontal portion that connects to the downspout

downspout

vertical piping that conveys rainwater downward within walls or columns

catch basin

located at the base of a downspout that directly connects to the storm drain pipe

area drain

installed in an exterior open area, used to collect surface runoff

junction box

device used to connect a number of drainage pipe that may converge and provide a single pipe on its outlet

storm drain pipe

pipe intended to collect rainwater or surface runoff and convey to storm water disposal

subsoil drain

collects subsurface water and disposes them

primary drainage system

basic storm water drainage system

secondary drainage system

any additional storm drainage system that will handle any storm water overflow

sump (storm water)

receptor that receives liquid waste or storm water below elevation

sump pump (storm water)

pump that removes liqud from sump

roof drain materials

cast iron, galvanized iron, copper, brass or other corrosion resistant materials

storm water system design principle

install a piping or leader system to lead the storm water away from the building
