10-Inch Inlet Products


This section contains 72 1" holes per foot and is used in standard conditions where a 10" flow rate is needed.

This is a 10" x 1" holed section with 9 1" x 4" slots per foot. It is used to provide more flow than a 10" x 1" section can provide and where a 12" x 1" section is too much. It can also be used in conjunction with a 10" restrictor to help eliminate trash build-up due to possible restriction of the 1" holes.

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. HBI-10R0 10" restrictor is molded into the bottom of this section.

This is a blank orange section that is used for offsetting the inlet from the main line. It can also be used in place of HBI-10516 when no small holes are wanted below ground.

This is a 10" new style tee that may be directly to 10" corrugated field tile or dual wall pipe.

This part adapts a 6" tee to a 10" riser section.

This part adapts an 8" tee to a 10" riser section.

This part adapts a 10" tee to a 6" riser section.

This part adapts a 10" tee to an 8" riser section.

10" Inlet Flowchart

  • Every Hickenbottom® Inlet is made of high-density polyethylene.
  • All Hickenbottom® parts, tees, offsets, risers, and inlets snap together for easy installation. Risers and inlets can be cut to desired lengths.
  • Markings on Hickenbottom® Inlets allow for easy height adjustment. Find the marking for the desired height and simply cut on the line.
  • Hickenbottom® Inlets are lightweight and simple. There is no need to hoist in concrete catch basins and no need to weld aluminum or steel pipe inlets.
  • Hickenbottom® Inlets are durable, easy to see, and easily maintained.
  • Check out Hickenbottom® adapters to increase or reduce the intake of the inlet off of the inletís tee. Contact your local NRCS office to properly size restrictors for your project.
  • A special inner riser may be inserted to maintain ponding at a certain level to improve water infiltration in semi-arid regions.
  • Hickenbottom® Inlets are government approved. There are authorized distributors in the U.S. and Canada that have inlets in stock for fast delivery to contractors.

General Information for Installation Practices


Installation for all Hickenbottom® Inlets should be in accordance with specifications for corrugated P.E. piping, such as ASTM F-405 and AASHTO highway specifications M-252. These can be found in the Soil Conservation Service Engineering Field Manual for Conservation Practices in Book 2 of 2, Section 8-82 and 8-83.

When back-filling inlets at shallow depths (less than 24 inches), it is recommended that one bed the tee and underground portion of the inlet with 1/2 to 1 1/2 inches of stone aggregate (ie: limey chips). In normal conditions concerning depths less than 24 inches (up to 72 inches), the spoil from the trench may be used for bedding if the size of the spoil material is less than 2 inches in diameter.

In conditions of 72 inches or deeper, one should surround the vertical portion of the inlet with a circumference of approximately 12 inches of the aforementioned aggregate to the surface.

To keep the vertical portion of the inlet from tipping over in the back-filling process, fill around the inlet in a mounding fashion then taper the slope down and away from the inlet to the bottom of the trench.

Make sure that all Hickenbottom® sections are snapped together before backfilling.
