Enviro-Flo® Trench Drain Series
The ENVIRO-FLO® Trench Drain Series is the first of its kind in trench drain technology, encompassing all the compelling qualities you look for when deciding on a manufactured sloping trench drain system. The lightweight, 100% polypropylene construction, along with the Enviro-Loc® mechanical interlocking joint, molded outlet connection for quicker and easier installations, and a complete selection of grate materials, make it contractor-friendly.
Design Approach
To select the proper drainage system:
- Identify the appropriate loading and fall conditions based on the anticipated traffic, site topography or other physical constraints.
- Calculate the length and depth of the catchment area.
- Identify rainfall intensity over the given area. Identify the output position, source and flow rate of the liquid to be drained.
- Determine runoff surface flow characteristics.
- Calculate required flow rate per section of drainage channel and its distribution (i.e., evenly or unevenly distributed).
- Select the system with the appropriate capacity for the conditions identified.
- Determine the number, size and positions of outlets to the drainage system.
- Determine the concentration of the chemicals to which the system may be exposed. See the Chemical Resistance Chart
- Select appropriate load class grate from illustrations in Enviro-Flo® Systems Grates to go with 9930 or 9931 channel systems listed on Load Rating and Application Guidelines.
