This is a regular commercial pit complete with grate.
Zurn makes a variety of trench and pit products. This pit has a removable collection basket.
This is a residential flow thru trench that can be used on driveways, sidewalks or patios.
We installed this particular trench/pit system in 1997 and it still functions well.
Commercial trench/pit use is very typical near doors.
Water no longer seeps into the building under door and window frames thanks to this trench/pit system.
