8 Inch Diameter

8InchStandpipe

Standpipe

This section contains 56 1″ holes per foot and is used in standard conditions where an 8″ inlet is needed for capacity.

8InchRiser

Riser

This is a 8″ x 5/16″ holed orange section used underground from the tee as a riser extension. It can be cut at different locations (as marked on section) to adjust the height of inlet.

8InchTee

Tee

This is an 8″ new style tee which can be used to connect directly to 8″ corrugated or dual wall tile.

8InchRestrictor

Restrictor

This is an 8″ restrictor used to adjust the flow of water from the inlet to the main line.

6InchAdapter

6" to 8" Adapter

This increaser adapts a 6″ tee to a 8″ riser section.

8InchAdapter

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 is either capped or the top of the inlet extends above the water elevation.
  • The perforations in the inlet extend as high as the water depth.
  • The flow in the inlet is not restricted by any other component of the system. For example, flow is not restricted due to an orifice plate, an offset pipe that limits flow, or full pipe flow in the mainline that could create a tailwater effect in the inlet.
