1. Pipe from House
2. Septic Tank
3. Drain field

Definition
| Household waste water exits thru a pipe that flows into septic tanks |
|
|
Term
|
Definition
| it is a buried, watertight container, holds solids long enough for sludge to occur, the tank needs to be pumped every 3-5 years |
|
|
Term
|
Definition
| when new water enters septic tank, the same amount of waste water exits the tank and is pushed into it. |
|
|
Term
|
Definition
| Septic tank wastewater flows to the drain field, where it percolates into the soil and is filtered. Natural processes remove contaminants in the wastewater before it eventually reaches groundwater. |

| 3 types of pervious surfaces |
|
Definition
1 porous asphalt
2 permeable pavers
3 grass pavers (aka turf blocks) |

Definition
| cheapest swale, but least reliable pollutant removal. Much like a conventional ditch but wider. usually acts as the first step in storm water treatment |

Term
|
Definition
dry: fabricated soil bed of sand/soil that meets minimum permeability requirements. has underdrain system of gravel
wet: vegetated with water tolerant vegetaion, designed to retain water. often used along highways |
|
|
Term
| retention/ detention ponds |
|
Definition
retention: to limit flooding and pollutant removal. catch runoff from higher eleavtion areas
detention: designed mostly for flood control. a low lying area to temporarily hold water while slowly draining to another location. |

|
Term
| Venting performs four functions |
|
Definition
1)At each fixture trap, air in the system (branch / vent stack) keeps atmospheric pressure at the trap
2)Exhausts sewer gases and odors to outdoors (stack vent)
3)Allows fresh air into the drain pipe (soil / main stack)
4)Aids the smooth flow of waste in the drain pipe (soil stack) |
|
|
Term
| stack vent VS vent stack: |
|
Definition
Stack vent: a vent extension of a soil/waste stack
Vent stack: a major supplier of air for a drainage system and is commonly used on multi-story soil or waste stacks. Must either terminate to outside air or be tied into a vent header. |
