Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

2. The running off of water from a land surface or subsurface - such as through sewers or natural means.






3. The oxidation ditch is a modified form of the activated sludge process. The ditch consists of two channels placed side by side and connected at the ends to produce one continuous loop of wastewater flow and a brush rotator assembly placed across the






4. A community's used water and water carried solids (including used water from industrial processes) that flow to a treatment plant. Storm water - surface water - and groundwater infiltration also may be included in the wastewater that enters a wastewa






5. OE The pressure at a specific elevation exerted by a body of water at rest - or _ In the case of groundwater - the pressure at a specific elevation due to the weight of water at higher levels in the same zone of saturation.






6. A system of gutters - catch basins - yard drains - culverts and pipes for the purpose of conducting storm waters from an area - but intended to exclude domestic and industrial wastes.






7. The pipe system for collecting and carrying water and watercarried wastes from domestic and industrial sources to a wastewater treatment plant.






8. Most plumbing codes require a vent pipe connection of adequate size and located downstream of a trap in a building wastewater system. This vent prevents the accumulation of gases or odors and is usually piped through the roof and out of doors.






9. That part of rain or other precipitation that runs off the surface of a drainage area and does not enter the soil or the sewer system as inflow.

11. Clarifier - Settling Tank. A tank or basin in which wastewater is held for a period of time during which the heavier solids settle to the bottom and the lighter materials float to the water surface.






12. A special valve with a hinged disc or flap that opens in the direction of normal flow and is forced shut when flows attempt to go in the reverse or opposite direction of normal flows.






13. Tamping or rolling of a material to achieve a surface or density that is able to support predicted loads.






14. A layer - usually of concrete or mortar - for providing continuous support to such items as bricks - slabs - pipes.






15. Regulations specifying the type of construction methods and materials that are allowable on a project.






16. The pipes - conduits - structures - equipment - and processes required to collect - convey - and treat domestic and industrial wastes - and dispose of the effluent and sludge.






17. A type of easement granting permission to a constructor or developer to build over a street or structure.






18. A strip of unspoiled - often treed - agricultural or other outlying land used to separate or ring urban areas.






19. A system of major sewers serving as transporting lines and not as local or lateral sewers.






20. Federal agency responsible for producing and managing many federally-funded public service programs - especially those affecting housing and public spaces.






21. A conservation group that maintains a revolving fund for quickly buying land that is in danger of being developed inappropriately or without regard to proper environmental considerations.






22. Harmonious use of the land for more than one purpose; not necessarily the combination of uses that will yield the highest economic return - e.g. - a mix of residential and commercial developments in the same area.






23. Rain and snow water accumulated in the earth's porous rock.






24. The angle between a horizontal line andthe slope or surface of unsupported material such as gravel - sand -or loose soil. Also called the 'natural slope.'






25. Load applied along or parallel to and concentric with the primary axis






26. The prepared and compacted base on which a manhole is constructed.






27. The height to which something is elevated - such as the height above sea level.






28. A groundwater table that is changed by artificial means. Examples of activities that artificially raise the level of a groundwater table include agricultural irrigation - dams and excessive sewer line exfiltration. A groundwater table can be artifici






29. The movement of water through very small spaces due to molecular forces.






30. A U.S. government agency charged with administering vast areas of public land.






31. A water service shutoff valve located in a water service pipe near the curb and between the water main and the building. This valve is usually operated by a wrench or valve key and is used to start or stop flows in the water service line to a buildin






32. The condition of water or soil which contains a sufficient amount of acid substances to lower the pH below 7.0.






33. The conversion of large solid particles of sludge into very fine particles which either dissolve or remain suspended in wastewater.






34. A wall that supports any vertical load in addition to its own weight.






35. Landscape architecture - (civil) engineering - urban planning and architecture. Agronomy is also often included in this group.






36. Branch or lateral sewers that collect wastewater from building sewers and service lines.






37. A chamber or well used with storm or combined sewers as a means of removing grit which might otherwise enter and be deposited in sewers. Also see STORM WATER INLET and CURB INLET.






38. The change to an area's natural resources - including animal and plant life - resulting from use by man. Some projects may require conducting of an 'environmental impact study' before development can proceed.






39. Horizontal shoring members - usually square - rough cut timber - that are used to hold solid sheeting - braces or vertical shoring members in place. Also called STRINGERS.






40. Material used to provide a bedding or foundation for pipes or other underground structures. This material is of specified quality for desirable bedding or other characteristics and is often imported from a different location.






41. The amount of liquid which a solid material can absorb. Sand - as an example - can hold approximately onethird of its volume in water - or three cubic feet of dry sand can contain one cubic foot of water. A denser soil - such as clay - can hold much






42. An unstable condition of a solution (water) in which the solution contains a substance at a concentration greater than the saturation concentration for the substance.






43. Masonry composed of roughly shaped stones fitting approximately on level beds - well bonded and brought at vertical intervals to continuous level beds of courses.






44. A preliminary plan showing proposed ultimate site development. Master plans often comprise site work that must be executed in phases over a long time and are thus subject to drastic modification.






45. A pipe or conduit that carries wastewater or drainage water. The term 'collection line' is often used also.

47. A sewer pipe to which building laterals are connected. Also called a COLLECTION MAIN.






48. Solid material settled from suspension in a liquid.






49. Railing support at landings or other breaks in the stairs. If an angle post projects beyond the bottom of the strings - the ornamental detail formed at the bottom of the post is called the drop.
