Storm Sewers

A conduit that carries rainwater, surface water, ground water, cooling water, or other similar flows to a point of safe discharge. Storm sewers help protect much of the land we use for agriculture, industry, transportation, residences and recreation. Concrete pipe with its impressive record of strength and durability, is the most economical and reliable choice of materials available today. Storm sewers require that pipe meet the strength requirements of any depth of fill and live load, are hydraulically efficient, non-combustible and provide resistance to abrasion.

Applicable Specifications and Recommended Use

Pipe and Special Shapes

ASTM C 14 Concrete Sewer, Storm Drain, and Culvert Pipe (non-reinforced)
C14 pipe is to be used for sizes 6" - 10" diameter.  It may be used for sizes 12" - 24" diameter with the provision that C 76 pipe of comparable strength also be specified.  Joints provided for most storm sewer construction employ cement mortar or mastic compound. For installations with internal or external head conditions, joints may be provided as per ASTM C 443 utilizing a rubber gasket.
 
ASTM C 76 Reinforced Concrete Culvert, Storm Drain, and Sewer Pipe
C 76 pipe is used for sizes 12" - 144" in diameter and is available with bell and spigot or tongue and groove ends utilizing cement mortar or mastic compound joints.  These joints are adequate for most storm sewer installations.  For special conditions of internal or external head, joints may be provided meeting the requirements of ASTM C 443 or ASTM C 361 utilizing a rubber gasket.  This type of pipe is the most commonly used storm sewer pipe because of its excellent hydraulic capacity, capabilities in meeting any variety of load conditions, and availability with a number of related appurtenances.
 
ASTM C 655 Reinforced Concrete D-Load Culvert, Storm Drain, and Sewer Pipe
C 655 pipe is used for sizes 12" - 144" diameters designed for specific D-Load strengths.  Joints provided for most storm sewer construction employ cement mortar or mastic compound.  The properties of the pipe are similar to ASTM C 76 pipe except that the pipe may be designed for a specific D-Load strength and the design accepted on the basis of a statistical analysis of test specimens.

Special Shape Pipe and Precast Concrete Boxes

Also available for storm sewer use are the following special shape pipe and precast boxes with the same characteristics and properties as given for sanitary sewers.
 
ASTM C 506 Reinforced Concrete Arch Culvert, Storm Drain, and Sewer Pipe
 
ASTM C 507 Reinforced Concrete Elliptical Culvert, Storm Drain, and Sewer Pipe
 
ASTM C 789 Precast Reinforced Concrete Box Sections for Culverts, Storm Drain, and Sewers
 
ASTM C 850 Precast Reinforced Concrete Box Sections for Culverts, Strom Drains and Sewers With Less Than 2’ of Cover Subjected to Highway Loadings.

ASTM C 1433 Standard Specification for Precast Reinforced Concrete Box Sections For Culverts, Storm Drains and Sewers.
C1433 Specification covers single-cell precast reinforced concrete box sections intended to be used for the construction of culverts for the conveyance of storm water, industrial wastes and sewage.

Joints

Cement Mortar and Mastic Compound
All pipe, special shapes and boxes are available with tongue and groove joints that may be packed with cement mortar, filled with a preformed plastic gasket sealing compound, or a trowel applied mastic compound.  Such joints have a successful experience record and are generally used for storm sewer construction.  Properly applied mastic joint fillers provide flexibility without impairing water tightness.
 
ASTM C 443 and C 361
For special conditions of internal or external head, joints may be provided utilizing a rubber gasket. C443 joints are primarily intended for use with pipe manufactured to meet the requirements of C 14 or C 76. C 361 joints are supplied for use with pipe manufactured to meet the requirements of C 76.  Details of joint descriptions and performance are the same as given for sanitary sewers. Compression type rubber gaskets are not available for other than circular pipe.
