ACO drainage systems are used in a variety of applications from domestic environments to airports. ACO Products have been used at many prestigious locations, including Olympic stadiums, since USA was founded in 1978 and is America s foremost manufacturer of trench drainage drain pioneersACO Drain is the market leading, modulartrench drain system and is manufacturedat the company s modern manufacturingfacilities in Ohio, Arizona and Drain offers the most comprehensiverange of trench drain solutions for everyapplication.

3 It preventsdamage to pavement or property, andreduces safety hazards caused byponding. Surface drainage is designed to: Reduce ponding (standing water) Reduce slip hazards and subsequent injury Protect, and extend, life of paved surfaces Protect property from flood damage Reduce inconvenience to public users Reduce hydroplaning on roadsOptions available: Ignore it Open swale Catch basins trench drainsFor solid pavements the first two are notideal. Catch basins or trench drains are themost viable drainageCatch basin drainage2004 Master Format CodesTrench drains and grates originally fell intoDivisions 2, 3, 5 and the expanded Master Formatcategories they now fall into the followingdivisions:03 48 00 - Precast Concrete Specialties05 53 00 - Metal Gratings22 14 00 - Facility Storm Drainage33 44 00 - Storm Drainage UtilitiesSurface DrainageACO Uneven, undulating appearance Complex, multiple grades to design andconstruct Deeper ground excavation due to pipedepths Higher risk of ponding Pipes prone to blocking and failure Maintenance can be difficult and costlyas access to pipe work is restricted Possible interference with otherservices, , electrical, sewage, etc.

4 Neat linear appearance Simple grades to design and construct Easy to install - shallower excavation andeasy grading of pavement Continuously intercepts water andprovides superior drainage Minimal underground pipes - lessexcavation and site disturbance Maintenance is quick and easy as trenchis at the surface and easier to accessSustainable drainage Sustainable drainage is an element of the Hydrological Cycle . It is the collection ofrainwater, its treatment and, ultimately, process involves capturing waterrun-off, that may or may not containpollutants, so it can be dealt with in acontrolled manner. The water can thenbe treated, stored for future use, ortransported to receiving waterways. Thistransfer of water should come at low cost,and cause minimal damage and danger tothe drainage can be used whererainwater has collected on paved areas forthe capture part of this drains are ideal for the capture andcollection of storm water run-off.

5 They forma barrier to prevent rainwater run-off flowingonto the soft landscaping where collectionis more difficult. This is of particularimportance if the risk of contaminationis high, such as highway and gas stationapplications. ACO provides a wide range of trenchdrains to meet the hydraulic needs of anysustainable drainage 'Leadership in Energy and EnvironmentalDesign'; provides a green Building ratingsystem. Principles have been applied tocommercial and institutional projects,schools, multi-unit residential buildings,manufacturing plants, laboratories and otherbuilding where the use of trench drainage mayassist in the assignment of credits include:SUSTAINABLE SITESC redit - Site DevelopmentCompared to catch basins, trench drainsrequire minimal excavation; reducing & - Stormwater DesignTrench drains capture run-off, enablingtreatment which prevents pollution of receivingstreams.

Compared toarea drains, trench drains require minimalexcavation; reducing site to polystyrene formers, FastFormcardboard formers are easier to dispose to for full Hydraulic performance2.

8 It is then carried to a point were itcan discharge into an underground pipesystem or flow accounts for liquid beingcarried in a trenchplusthe constantaddition of liquid collected through thegrates along the trench run - lateral characteristic of non-uniform flow isthat liquid velocity and height change atsuccessive cross sections along the correctly model this situation, differentialcalculus is required; usually computermodeling is a result of empirical testing, ACO hasdeveloped a computer program, Hydro ,that models trench provides a complimentary service for trench hydraulics. See page 110 for commonly used method of calculatingtrench hydraulics involves the use ofequations for steady uniform approach is better suited for pipedesign where liquid velocity and heightremain constant along the is made for lateral , uniform flow can be used in culvert(open top) design for dams or irrigationtrenches.

Catchment area - length x width ofpavement (ft) Rainfall intensity in inches per hourOnce catchment run-off Q is calculated, otherinflows, , down spouts, can be factors that affect how much liquidreaches the trench and how quickly; Ground fall percentage Pavement material - some materialsabsorb liquids, , brick pavers Position and size of outlet pipe Surface roughness of s coefficient ofroughness figures are available Angle of approach to trench - thiscan affect grate hydraulics (steepslopes may cause bypass)Once run-off is calculated, it is usedwith the other factors above to determinethe correct size of trench .

10 The trench sizeis dictated by the clear opening and invertdepth - changing either or both of these willcreate a smaller or larger flow area . Clear opening of trench is the normal specified dimension, , 4 , 8 , etc. Overall grate and outside trench dimensions are misleading. Some trench drain companies promote these sizes to mislead specifiers and installers, , overall trench dimension of 6 . Usually clear opening will be approx. 4 - this is the dimension available for hydraulic flow, not 6 .QCatchment hydraulics - calculating run-offClear opening, orwidth, is often chosenin conjunction withstandard grate of trench canvary along its lengthif slope is introducedinto the base of thetrench. Some factors,such as slab depth,can influence dimensionsdictate the physicalfit of the trench in thelocation.
