Describe how trench drainage systems can help reduce project costs. 3

6. The process of drainage has been around for many years.

7. Trench drainage (floor trench) can be referred to as: channel drainage, line drainage, trip drainage and slot drainage.

8. Trench drains are considered to be an open trench with removable grates. Slot drains are a slot in the pavement connected to underground drains and to not have removable grates.

9. Generally a trench is regarded as the completed job in the ground. A channel is an individual modular piece which when added to others makes up the drainage system.4

22. Cast in Place Trench Drains7

24. Complex, multiple grades to design and construct.

25. Deeper excavation required due to pipe depths.

26. Higher risk of ponding.

27. Pipes prone to blockage and failure.

28. Maintenance can be difficult and costly since piping is not accessible.

29. Possible interference with other utilities, i.e. electrical, sewage, etc.8

31. Time consuming due to on-site formwork.

32. Hand-formed poured-in-place concrete trenches often are not uniform in the slope.

33. Concrete absorbs water.

34. Difficult to get a uniform slope.9

36. Debris and standing water result from slower flow and create unsanitary conditions

37. Concrete is attacked my mild acids, caustics and saltwater

38. Concrete patching is difficult and time consuming

39. Grates often have to be ground or otherwise modified to fit and to keep from rocking10

41. Simpler grades to design and construct

42. Easier to install due to shallower excavation and pre-sloped sections make it easier to construct since slope is built in

43. Continuously intercepts water and provides superior drainage

44. Minimal underground piping

45. Maintenance is quicker and easier since trench is at surface

46. Less interference with other utilities since excavation is shallow11

48. Animal Facilities

49. Stadiums and Sporting Facilities

50. Fire Stations

51. Vehicle Maintenance Facilities

52. Pools

53. Airports

54. Manufacturing Plants

55. Lawn and Garden Centers

56. Retail Stores

57. Parking Lots12

59. Closed cell structure of polymers and negligible water absorption prevents collection of bacteria and stops gasoline and other pollutants from getting into the soil.

60. Highly chemical resistant. Not eroded by cleaning agents in wash-down water in food processing plants.

61. Easily maintained since smooth, radius channels don’t collect debris.13

63. Traffic type and frequency

64. Wheel size and type

65. Static versus dynamic loading

72. Installation

73. User Requirements – project specific options

74. Aesthetic – visual look requirements

75. Safety – ADA (Americans with Disabilities Act) requirements, pedestrian requirements – ladies heels, slip resistant finish, etc.

76. Security – ease of removal of grate15

78. .39 * 7.48 * 60 = 175 GPM

79. 175 GPM is the total volume flow rate required for the catchment area.16 65’ 130’

80. Step 2. Decide on correct layout. Since the trench exceeds 100 feet in length and we would rather not use extension walls, the catch basin will be placed in the center and slope each end to the catch basin. 65’ 65’ 17 Sizing a Modular Trench Drainage System Example – Step 2

82. Channel sections are bolted together.

83. Channel sections available with flashing flange and flashing clamp.

102. Water Treatment Plants

104. The shallowest channel is 13.06” and the deepest channel is 17.81”.

105. Closing end caps and horizontal outlet caps provide for a complete drainage system.

106. Strengthening ribs on the channel sides create a stronger and safer system capable of withstanding the considerable loading imposed by the turning action of heavy wheeled vehicles.

124. Case Studies 25 Trench Drains at University of Cincinnati The UC Trabert-Talbert Tennis Center consists of a six-court tennis complex with a central grandstand and was constructed over a 150-car underground parking garage. Due to the tennis courts being located above the parking garage, a trench drain with flashing was required to prevent any water leaks into the parking garage. A membrane drain with waterproofing clamping system was provided for the project.

125. Case Studies 26 Automotive Service Center A fortune 250 company built a large scale, high end luxury automobile showroom in central New Jersey. They requested a solution that could be designed and installed without delays and with minimal disruptions. A high capacity pre-sloped fiberglass trench drain system was provided for the project.
