drainage Flashcards
what is stormwater drainage
Systems that are put in place to help prevent floods by diverting rainwater into nearby waterways that flow into underground pipes which flows to streams,ponds or reservoirs
what are Foundation drains (1.)
Foundation drains are pipes that are installed under your foundation or basement floor to collect water and move it off-site to prevent your basement from filling with water.
Gutter(2.)
a shallow fixed beneath the edge of a roof for carrying off rainwater.
Downpipe (3.)
downpipe is a pipe that is used to direct rainwater away from a building, typically from roof guttering to a drainage system. It is sometimes also referred to as a downspout, drain spout, roof drain pipe or leader
Catchpit (4.)
A Catchpit is essentially an empty chamber with an inlet pipe and an outlet pipe set at a level above the floor of the pit. Any sediment carried by the system settles out whilst in the Catch-Pit, from where it can be periodically pumped out or removed.
why install a French drain (5.)
French drains are primarily used to prevent ground and surface water from seeping into building foundations, however, are many reasons why people will install a French drain to redirect surface and ground water. These drains are often used to remove excess water from low areas, or extremely wet areas of the property.
channel /trench drain (6.)
A trench drain (also channel drain, line drain, slot drain, linear drain or strip drain) is a specific type of floor drain containing a dominant trough- or channel-shaped body. It is used for the rapid evacuation of surface water or for the containment of utility lines
Drywell (7.)
a shaft or chamber constructed in the ground in order to aid drainage, sometimes containing pumping equipment.
a.k.a. dry hole.
storm sewer (8.)
a sewer built to carry away excess water in times of heavy rain; a storm drain.Storm drain inlets are typically found in curbs and low-lying outdoor areas.
what does a Sump pump(9.) do
he sump pump’s job is to pump the water out of the pit and away from the building so the basement or crawlspace stays dry.
What is grey water
the relatively clean waste water from baths, sinks, washing machines, and other kitchen appliances.
A grey water system usually consist of
- ________
- _______
- _______
- _______
- _______
- Plumbing system- made out of pipes and valves to capture the grey water
- surge tank - to temporarily hold large drain flows (WM/ Bath)
- filter- to remove particles which could clog the irrigation system
- pump - to move water from the surge tank to the irrigation system
- irrigation system - to distribute water to plants
rainwater harvesting
Rainwater harvesting (RWH) is the collection and storage of rain, usually collected from roofs (via gutters)
rainwater harvesting vs stormwater harvesting
rainwater harvesting is collected from roofs or elevated surfaces where as stormwater harvesting is collected from creeks, drains, roads or any other land surfaces
