  • 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.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Masonry composed of roughly shaped stones fitting approximately on level beds - well bonded and brought at vertical intervals to continuous level beds of courses.

2. A type of wastewater or service connection pipe made of a low grade of cast iron. _ In plumbing - a pipe that carries the discharge of toilets or similar fixtures - with or without the discharges from other fixtures.

3. The taking in or soaking up of one substance into the body of another by molecular or chemical action (as tree roots absorb dissolved nutrients in the soil).

4. Not easily penetrated. The property of a material or soil that does not allow - or allows only with great difficulty - the movement or passage of water.

5. A legal form of land-use control and building regulations usually exercised by a municipal authority; usually involves setting aside of distinct land areas for specific purposes - such as commercial - educational or residential development.

6. A wastewater treatment process used to convert dissolved or suspended materials into a form more readily separated from the water being treated. Usually the process follows primary treatment by sedimentation. The process commonly is a type of biologi

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

8. A capped opening in a building lateral -usually located on the property line - through which the pipelines can be cleaned.

9. A wall or plate placed in an open channel and used to measure the flow of water. The depth of the flow over the weir can be used to calculate the flow rate - or a chart or conversion table may be used to convert depth to flow. A wall or obstruction u

10. In zoning - a housing or commercial development composed of individual units that are regulated as a whole.

11. A site that might appear to be natural but has elements and features that were planned and specified by a landscape architect. Designed landscapes include Central Park in New York to the siting of buildings.

12. Water that does not contain objectionable pollution - contamination - minerals - or infective agents and is considered satisfactory for drinking.

13. A biological wastewater treatment process which speeds up the decomposition of wastes in the wastewater being treated. Activated sludge is added to wastewater and the mixture (mixed liquor) is aerated and agitated. After some time in the aeration tan

14. Masonry composed of roughly shaped stones - well bonded and brought at irregular intervals vertically to discontinuous but approximately level beds or courses.

15. A downspout or pipe installed to drain a roof gutter to a storm drain or other means of disposal.

16. A material - other than aggregate - cementitious material or water - added in small quantities to the mix in order to produce some (desired) modifications - either to the properties of the mix or of the hardened product.

17. The pipeline extending from the water main to the building served or to the consumer's system.

18. A large - public park - often highly scenic and isolated belonging to and operated by the federal government.

19. The upper surface of the zone of saturation of groundwater in an unconfined aquifer.

20. Shoring members placed across a trench to hold other horizontal and vertical shoring members in place.

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

22. A natural underground layer of porous - waterbearing materials (sand - gravel) usually capable of yielding a large amount or supply of water.

23. An arrangement of pipes - equipment - devices - tanks and structures for treating wastewater and industrial wastes. A water pollution control plant.

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

25. Movement of soil from one place to another. Generally accompanies SILTING of a sewer system. Where infiltration is taking place and silt is carried into a sewer system - such silt or soil is removed from the ground around the sewer pipe and the resul

26. The elevation of the invert (or bottom) of a pipeline - canal - culvert - or similar conduit. _ The inclination or slope of a pipeline - conduit - stream channel - or natural ground surface; usually expressed in terms of the ratio or percentage of nu

27. The illustration and description of problem-statements and large-scale design solutions that affect extensive areas of land; the anticipation of problems that will be encountered as human use and development of land continues.

28. A trained builder or installer of landscapes - retained to implement the plans of landscape architects.

29. A railing composed of balusters capped by a handrail.

30. British thermal units; the quantity of thermal energy required to raise one pound of water at its maximum density - 1 degree F. One BTU is equivalent to .293 watt hours - or 252 calories. One kilowatt hour is equivalent to 3412 BTU Back Pressure (wat

31. 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.

32. A pipe or conduit (sewer) intended to carry wastewater or waterborne wastes from homes - businesses - and industries to the POTW (Publicly Owned Treatment Works). Storm water runoff or unpolluted water should be collected and transported in a separat

33. Material used for backfilling a trench or excavation which was not the original material removed during excavation. This is a common practice where tests on the original material show it to have poor compactability or load capacity. Also called BORRO

34. Post at which the railing terminates at each floor level.

35. 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.

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

37. 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

38. A groundwater table that has seasonal changes in depth or elevation.

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

40. A reactor or basin in which baffles or other devices create a series of compartments. The environment and the resulting microbial population within each compartment can be controlled to some extent by the operator. The environmental conditions (food

41. The movement or dislocation of underground soil or structure. Earth shift is usually caused by external forces such as surface loads - slides - stresses or nearby construction - water movements or seismic forces.

42. A sewer designed to carry both sanitary wastewaters and storm or surface water runoff.

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

44. The legal grant of right-of-use to an area of designated private property.
