Standpipe
This section contains 72 1" holes per foot and is used in standard conditions where a 10" flow rate is needed. A built-in adjustable restrictor is molded into the bottom of this unit.
Riser
This is a holed orange section that is used underground from the tee as a riser extension. It can be cut at different locations (as marked on section) to adjust the height.
Tee
This is a 10" new style tee that may be directly to 10" corrugated field tile or dual wall pipe.
8" to 10" Adapter
This increaser adapts a 8" tee to a 10" riser section.

The capacity charts are based on the following assumptions:
- 50% of the holes in the inlet are plugged.
- There is no flow through the top of the inlet. The top of the inlet i either capped or the top of the inlet extends above the water elevation.
- The perforations in the inlet extend as high as teh water depth.
- The flow in the inlet is not restrited by any other component of the system. For example, flow is not restricted due to an orifice plate, and offset pipe that limits flow, or full pipe lfow in the mainline that could create a tailwater effect in the inlet.
