Chanter
* Some chanters have a 'sole' at their bottom end for decorative purposes.
* are part of bagpipes
  - the people who conduct ceremonies
* sing, sway, or lead choruses of sacred songs on high holy occasions.

Concrete pipe
* is one of the strongest and most durable materials used in making culverts.
* rigid pipe that has significant structural strength.

Copper pipe
* are lightweight because they can have thin walls
  - reddish-colored metal pipes that are often used to carry water through homes
* carry water throughout the home.

Culvert
* are barriers to migration
  - drains
  - pipes that bring water under a road or trail
* can block fish passage and alter water flow.
* concentrate and accelerate water which increases soil erosion proportionally.
* often create barriers to the upstream migration of juvenile fish.
* perched above the level of the stream bed can also prevent fish migration upstream.
* represent an economical way of constructing a permanent crossing on small streams.
* run under piles to deliver humidity and oxygen to the pile of potatoes.

Cloaca
* Some cloacas result in slow death.
* connect intestines.
* includes readsides
  - sections

Sewer
* All sewers have some odors.
* Some sewers abound in reflective surfaces
  - prefer to use a rotary cutter rather than scissors
* also provide habitat, and access to street level feeding areas, particularly in cities.
* are artifacts
  - great sources of food and water for rats
  - located in streets
  - part of sewage systems
* collect the liquid waste and discharge it into lakes, streams or the ocean.
* have a way of hiding tracks after the beasts crawl out.
* means a pipe or conduit for carrying sewage.
* overflow can lead to potential river contamination
  - occur in any community with inadequate systems when it rains

Open sewer
* drain foul-smelling, brown water into a nearby river.
* flow down the dirt streets, which are deeply rutted by erosion.

Sanitary sewer
* are to be provided solely for the collection and transport of sanitary waste.
* carry household, industrial, and commercial wastewater
  - wastes from homes, industry, and businesses to treatment plants
  - wastewater to treatment plants

Storm sewer
* are also significant routes for pollutant input.
* carry runoff from miles of city streets and rooftops into waterways
  - rain or snow
  - rainfall to the nearest stream, river, lake or ocean
  - stormwater to the nearest stream, river, lake or ocean
* drain to rivers or lakes and carry oils, chemicals and trash.
* operate on a separate system.
* provide direct routes for pollutants to lakes and streams.

Exhaust pipe
* are part of automobiles
  - cars
  - exhaust
  - the source of all wind
* can start fires in the dry grass.
* emit carbon monoxide gas and can cause burns.

Heat pipe
* Most heat pipes used in electronic cooling are copper with water or alcohol as the working fluid.
* Some heat pipes consist of pipes.
* are a special form of heat movement using phase change convection
  - devices used to passively remove heat from electronics on spacecraft
* are extremely effective in transferring heat from one location to another
  - efficient heat transfer devices
  - thermal management devices used on many existing spacecraft for waste heat removal
* have an effective thermal conductivity many thousands of times that of copper.
* repair basically involves replacement of deteriorated parts.
* save electricity in another way as well.
* vary greatly in size, depending upon their particular use.

Kimberlite pipe
* All kimberlite pipes are overlain by small lakes.
* occur in northwestern part of the island.
