High Density Polyethylene Pipe (HDPE): N-12 dual wall pipe with its smooth interior wall and corrugated exterior wall, offers exceptional hydraulics and strength. Built using application specific high-density polyethylene, N-12 corrugated pipe also provides superior corrosion and abrasion resistance making it an excellent alternative to reinforced concrete and corrugated metal pipe. These properties have led to the increasing approval and acceptance of N-12 drainage pipe in storm water applications across the country.


Corrugated Metal Pipe: With a wide variety of pipe material, thicknesses, corrugations and coatings, G & O Supply Co., Inc. provides a diverse product line for varying service life, hydraulic and economic needs to help you tackle the full range of flow applications. Each of our solutions is designed for hydraulic efficiency, ease of handling and installation, durability and, of course, economy.

Corrugated Metal Pipe is available in diameters from 12” – 144” round and pipe arch with 2 2/3 x 1/2, 3x1, & 5x1corrugations. We offer Galvanized, Asphalt Coated, Asphalt Coated with Paved Invert, Aluminized Steel Type 2, & Polymer coatings to meet the service life needed for your drainage project. Our CMP is offered in 16, 14, 12, & 10 gage thickness steel meeting AASHTO specifications.

HDPE Fittings

HDPE Fittings: G & O Supply Co., Inc. stocks the largest line of HDPE fittings in the State of MS. Whether your drainage project calls for split couplers, bell couplers, bell and spigot joining systems, or gaskets.

G & O Supply Co., Inc. has a fitting solution for any drainage application.

HDPE Fittings
CMP NRCS Structures

CMP NRCS Drainage Structures: G & O Supply Co., Inc. provides NRCS Structures to include: Risers, Box Inlets, Slotted Inlets, Hooded Inlets, etc. All products meet or exceed NRCS Standard specifications.

Underground Detention

Underground Detention Systems:  Underground Detention/Retention Systems are available in both HDPE and CMP pipe. These structures allow for the most effective & efficient use for development of land when on site storage is needed and provide a low maintenance cost to the land owner while posing little or no aesthetic problems to the site.

Structural Plate

Structural Plate Products: Structural Plate Products include Galvanized Steel Multi-Plate & Aluminum Box Culverts for use in large culvert, storm sewers, vehicular & pedestrian tunnels, and stream enclosure applications. They especially perform well in those applications requiring higher cover. These structures are corrugated, pre-curved panels for field assembly and installation. A variety of shapes, sizes, and gages are available meeting your project requirement.

Geotextile Fabric

Geotextile Fabrics: Non Woven & Woven Geotextiles are made quality polypropylene fibers and are needle-punched to form a stable fiber network. Applications for geotextiles include: subsurface drainage, separation, stabilization, & cushioning

Erosion Control

Erosion Control: Available in temporary & permanent mats, our erosion control blankets & turf reinforcement mats are used for moderate flow storm water channels, banks, and steep slopes where both immediate and long-term erosion protection is needed.

  • Erosion Control Blankets

  • Turf Reinforcement Mats

  • Straw Wattles

  • Silt Fence


Tensar® TriAx® Geogrid is an advanced product specifically designed for trafficked surfaces. TriAx Geogrid’s multi-directional properties leverage triangular geometry, one of construction’s most stable and widely utilized shapes, to provide an enhanced level of in-plane stiffness. Its triangular structure, coupled with improved rib and junction geometry, offers the construction industry an improved alternative to conventional materials and practices.  TriAx Geogrid is manufactured from a punched polypropylene sheet oriented in multiple, equilateral directions to form its triangular aperture, resulting in high radial stiffness throughout the full 360 degrees. This feature yields a more efficient product that delivers optimal in-service stress transfer from the aggregate to the stabilizing geogrid.

Nyloplast Drain Basins: Nyloplast ® Drain Basins are used as a collection point typically where two or more drain lines converge. Basins can provide a transition between different sizes and types of pipe, and can also change the elevation or direction of the pipe. Drain Basins are also beneficial when faced with shallow pipe burial applications. Nyloplast Drain Basins can be installed in an H-20 compliant manner using the procedures outlined in the Installation Details found under the Drain Basin Resources
