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






2. 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.






3. A sewer that receives wastewater from many tributary branches or sewers and serves a large territory and contributing population.






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






5. A tank used to store a chemical solution of known concentration for feed to a chemical feeder. A day tank usually stores sufficient chemical solution to properly treat the water being treated for at least one day. Also called an AGE TANK.






6. Precipitation which has been rendered (made) acidic by airborne pollutants.






7. Any attempt to restore to beneficial use land that has lost its fertility and stability; most often applies to mining reclamation - such as the restoration of strip mines and quarries.






8. Installation of pumps to lift wastewater to a higher elevation in places where flat land would require excessively deep sewer trenches. Also used to raise wastewater from areas too low to drain into available collection lines. These stations may be e






9. A coordinating agency formed in 1961 for state boards that administer licensing exams and maintain records for landscape architects to practice.






10. An opening or point of access in a building wastewater pipe system for rodding or snake operation.






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






12. 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.






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






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






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. 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.'






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






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






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






20. 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






21. Material used in backfilling of an excavation - selected for desirable compaction or other characteristics.






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






23. Sand - silt - gravel and rocks carried or washed into a collection system by infiltration water flows.






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






25. 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.






26. 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






27. The lowest point of the channel inside a pipe - conduit - or canal.






28. 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.






29. 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.






30. A professional society that represents landscape architects in the United States and Canada and seeks to better the practice and understanding of landscape architecture through education - research - state registration and other programs.






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






32. A manhole which fills and allows raw wastewater to flow out onto the street or ground.






33. In landscape architecture - a study of the potential cost of site purchase - demolition and improvement in comparison to the income or other benefit to be derived from site development.






34. A sewer that discharges into a branch or other sewer and has no other common sewer tributary to it. Sometimes called a 'street sewer' because it collects wastewater from individual homes.






35. 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






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






37. A manhole in which the rate of the water entering is greater than the capacity of the outlet under gravity flow conditions. When the water in the manhole rises above the top of the outlet pipe - the manhole is said to be 'surcharged.'






38. The process of adding air to water. Air can be added to water by either passing air through water or passing water through air. In wastewater treatment - air is added to freshen wastewater and to keep solids in suspension. With mixtures of wastewater






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






40. In the United States - a certification of individuals entitled to use the term 'landscape architect' or to practice landscape architecture or both - by means of examination and required degree and experience criteria.






41. 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.






42. The used household water and watercarried solids that flow in sewers to a wastewater treatment plant. The preferred term is WASTEWATER.






43. Any method of determining the weight a compacted material is able to support without damage or displacement. Usually stated in pounds per square foot.






44. 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.






45. A system used where wastewater collection systems and treatment plants are not available. The system is a settling tank in which settled sludge is in intimate contact with the wastewater flowing through the tank and the organic solids are decomposed






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






47. Material used to fill in a trench or excavation






48. Downward movement of the soil or of a structure which it supports






49. 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.






50. 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
