Commercial and residential properties depend on trench drains (sometimes called channel drains) to redirect excess storm water and waste water runoff from creating unsafe surface-pooling on driveways and parking lots.
The purpose of a trench drain is to collect excess water from a driveway or parking lot, and direct it to a small-scale catch basin. Further water treatment depends on whether the runoff is contaminated or non-contaminated. For example, commercial garages, gas station parking lots and car washes that clean vehicles’ oily undercarriages all rely on trench drains to intercept and redirect water, to prevent runoff of oil, gas, or other liquids to the surrounding environment
Trench drains are designed to direct non-contaminated runoff to a dry well/leaching chamber that disperses the water. Contaminated runoff is first directed to an oil/water separator before the water is transmitted to a dry well or city drain/catch basin.
When accurately specified and properly installed, these systems:
The design of the system depends on calculations and factors such as the number of catch basins required; amount of rainfall anticipated per catch basin; anticipated weight loading, and more.
Precast Concrete Trench Drains – are considered the strongest, most cost-effective, low-maintenance solution for our harsh northeast climate. See below for sizes and benefits of precast concrete drain systems manufactured and installed by A.J. Foss.
Plastic Channel Drains – can only be used for residential driveways since they are not engineered for vehicular weight – unless they’re encased in concrete – so the preferred solution is to install a precast concrete system.
