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.
