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.

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. A septic tank or other holding tank which serves as a temporary wastewater storage reservoir for a Septic Tank Effluent Pump (STEP) system. See SEPTIC TANK.






2. 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.






3. 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.






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






5. A water treatment process in which solid particles settle out of the water being treated in a large clarifier or sedimentation basin.






6. 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.'






7. Vertical member supporting the railing.






8. 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.






9. The man-made creation of or alterations to a specific area - including its natural resources. This is in contrast to the 'natural environment.'






10. A rough guess of the amount of flow in a collection system. When greater accuracy is needed - flow could be computed using average or typical flow quantities. Even greater accuracy would result from metering or otherwise measuring the actual flow.






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






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






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






14. A record of each person involved in the handling and possession of a sample from the person who collected the sample to the person who analyzed the sample in the laboratory and to the person who witnessed disposal of the sample.






15. 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






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






17. Material used to fill in a trench or excavation






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






19. 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






20. Water or wastewater flowing from a higher elevation to a lower elevation due to the force of gravity. The water does not flow due to energy provided by a pump. Wherever possible - wastewater collection systems are designed to use the force of gravity






21. Acronym for 'Computer Aided (i.e. - Assisted) Design and Drafting -' a digital design process in which landscape architects use computers to help produce precise drawings and details for the construction of a project.






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






23. A professional who designs - plans - and manages outdoor spaces ranging from entire ecosystems to residential sites and whose media include natural and built elements; also referred to as a designer - planner - consultant. Not to be confused with lan






24. Sedimentation basin overflow weir. A plate with Vnotches along the top to ensure a uniform flow rate and avoid shortcircuiting.






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






26. The creative illustration - planning and specification of space for the greatest possible amount of harmony - utility - value and beauty.






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






28. In landscape architecture - an essential sheet showing site boundaries and significant site features - used as a basis for subsequent plan development.






29. One or a series of oneinch diameter holes through a manhole lid for purposes of venting dangerous gases found in sewers.






30. 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.






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






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






33. A manhole located at the upstream end of a sewer and having no inlet pipe. Also called a DEADEND MANHOLE.






34. A structure made of concrete or other durable material to protect bare soil from erosion by splashing or falling water.






35. Masonry composed of irregularly shaped stones laid without regularity of coursing - but well bonded.






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






37. An agency of the U.S. Department of Agriculture - primarily responsible for planning and overseeing the use of national forest lands by private - commercial and government users.






38. 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






39. A receptacle designed to collect and retain grease and fatty substances usually found in kitchens or from similar wastes. It is installed in the drainage system between the kitchen or other point of production of the waste and the building wastewater






40. 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.






41. An authorization issued by a government agency allowing construction of a project according to approved plans and specifications.






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






43. The lay of the land - particularly its slope and drainage patterns; the science of drawing maps and charts or otherwise representing the surface features of a region or site - including its natural and man-made features.






44. Narrowly defined - the amount of countryside and/or city that can be taken in at a glance. Also - an area of land or water taken in the aggregate.






45. That part of the precipitation falling on a drainage area which does not escape as surface stream flow during a given period. It is the difference between total precipitation and total runoff during the period - and represents evaporation - transpira






46. A multinational organization of landscape architects whose purpose is the promotion of landscape design and planning.






47. Broken stones - boulders - or other materials placed compactly or irregularly on levees or dikes for the protection of earth surfaces against the erosive action of waves.
