Why Trench Drain? Why Roadway Trench Drainage? Standing Water on Roadways is a Known Hazard for Hydroplaning. New Development Changes Alters Hydrology Hydrology Plan Issues Construction Issues Failing to address Known Hazards May Open Liabilities. These Products are Designed to Help Save Lives & Reduce Liability! Why Trench Drain?...And to Prevent This Type of Design! Why Trench Drain? Case Study Using hydraulics to save lives Road grading created cross road water flow causing traffic accidents. Solution was to install trench drain in central median strip. Trench hydraulic calculations and grate intake calculations were carried out. Due to road steepness or cambers in some areas, large trench s were required. A more cost effective solution was to use double runs of smaller trench s. No accidents were reported in the following 4 years Summary: Trench Drain used to achieve safest and most cost effective solution 2

CurbDrain Use with Other Products Rear Outlet to Retention Areas Load Testing DIN19580 Trench system Test There is currently no American test standard that covers ALL trench drain sizes and applications. Most standards are written for large catch basins. Commonly referred to: ASME A112.21.1M - 1991 Plumbing specification relating to internal drains AASHTO Standard specification for highway bridges - Load details for bridge design A-A60005 Federal Specification - Frames, covers,gratings,steps,sump and catch basin, manhole castings General product specs FAA AC: 150/5370-10 item D-751 Manholes, catch basins, Inlets and Inspection holes - Airport product and material specs DIN19580 4 Grate Test DIN19580 8 Grate Test 24
Gratings are subjected to BENDING loads. Trench drain bodies are subject to COMPRESSIVE loads. Tests should represent these conditions. Grate testing is the most important, and most often misrepresented. Grate Testing Understanding the test DIN TEST - test block (3 x10 ) applied to a 6 inch wide grate (to fit 4 inch clear opening trench) bending pressure is applied to grate Same grate subject to test load applied through 9 x9 test block.

Design Suggestions Design for ½ - ¾ Capacity to allow the best scouring velocities. Too Slow Flow, TSS Falls Out! CORRECT SIZE OVERSIZE Sir George Gabriel Stokes New installation Both trenches are used to drain same amount of liquid. Accurate & Inaccurate way to calculate trench hydraulics:- Non-uniform flow (Spatially Varied Flow) Also referred to as steady, non-uniform flow. Water is constantly added along length from lateral inflow. To calculate trench capacity requires differential calculus and computer modeling Water velocity and flow cross section area vary along the trench Steady, uniform flow (pipe theory) usually Manning's. Suited to trenches that carry flow ONLY from upstream origin - nothing is added along trench Water velocity and flow cross section area remain constant along the trench Correct profile option is determined by location. Neutral invert zero ground fall Invert depth of trench parallel to top edge of trench (ground surface level) Depth restrictions e.g.. elevated slab applications Neutral invert ground fall Ground slope of pavement same as trench base (invert) slope Ground slope generates flow velocity Improved hydraulic performance Sloped Invert zero ground fall Slope at base of trench (invert) gets deeper compared to top edge (ground surface level) Trench invert slope generates flow velocity Improved hydraulic performance Sloped Invert ground fall Ground slope and additional slope at base of trench Trench invert slope generates flow velocity Increased hydraulic performance 28
Poor Design or Placement on Left. Correction on Right. Storm water Management Options EPA Phase II- To reduce the quantity and/or increase the quality of drainage to municipal separate storm water sewer systems (MS4) Dependant up population density. Next phase will lower population density to include more areas. Increased Enforcement began in 2008 using contract audit companies. Trench drain can be an part of a Storm Water Management Plan & help to qualify as a SWM-BMP. Basket Inserts Hydrocarbon Capture Easy To Outlet to Water Quality Unit or Other Treatment Device 29
