Storm Sewer

Storm Sewer

Storm sewer pipes provide drainage for groundwater and rainwater from parking lots, streets, roofs, and other impervious surfaces. We offer a wide breadth of solutions and materials to assure the ideal drainage plan for your particular challenge.

CMP Pipe for Storm Sewers

CMP for Storm SewerNo other type of drainage structure offers the range of structural strength that’s available with CMP - performs where rigid pipe fails. We offer coatings and linings to increase the life of installations up to 100 years as well as provide products with a Manning’s “n” equivalent to other smooth wall drainage products. We provide a full range of CMP for severe-to-normal conditions.

DuroMaxx for Storm Sewers

DuroMaxx DetentionDuroMaxx drainage pipe is ideally suited for the collection and removal of stormwater from highway, urban, industrial and residential projects. Its unique combination of steel reinforcement and pressure rated HDPE resin allows it to perform like no other drainage pipe on the market. Its 80 ksi high strength steel provides maximum load carrying capabilities with allowable cover limits ranging from 30 to 50 feet. High strength steel provides exceptional shape and deflection control even on warm, sunny days where typical corrugated HDPE drainage pipes fall short. Pressure rated HDPE resin provides unmatched durability. Abrasion and chemical resistance is unaffected by water pH levels unlike reinforced concrete pipe, where abrasion resistance varies with water pH levels. Joint tightness available for all applications - 15 psi high profile (HP), 3 psi low head (LH), ElectroFusion (EF); and soil tight (ST) joints available.

Smooth Cor Pipe for Storm Sewer

SmoothCor for Storm SewerThe rugged, corrugated steel shell of Smooth Cor pipe supplies the structural strength to outperform rigid pipe, while a smooth interior steel liner provides a Manning’s “n” of 0.012. This combination makes Smooth Cor pipe both the economical and performance alternate to concrete in many difficult situations such as weak soils, poor subsurface drainage conditions, steep slopes, and high fills.

A-2000 and D-2000 for Storm Sewers

A-2000 Storm SewerIn recent years, the use of thermoplastic pipe for stormwater drainage systems has gained wide acceptance—based upon performance and economic advantages when contrasted with more conventional drainage pipe materials. However, when it comes to performance, not all thermoplastic storm sewer pipes are equal. There are distinct differences between A-2000 and D-2000 Polyvinyl Chloride (PVC) drainage pipes in comparison with other drainage pipes that can affect overall pipe system performance.

Slotted Drain for Drainage

Slotted Drain for DrainageSlotted Drain is a continuous opening inlet that efficiently removes surface water on streets and highways. The grate on a standard 20-foot length of Slotted Drain will intercept up to 50% more runoff than most standard 2’ x 2’ grate inlets. In parking lots, Slotted Drain removes sheet flow without complex multiple grades or water channeling devices like asphalt dikes, berms and curbs.

Flow Control for Storm Sewer Systems

Flow ControlOur Vortex Valve and StormGate bypass structures can be used wherever there is a need to limit the rate of flow of surface stormwater within a drainage system. Applications include, traditional attenuation storage, upstream of stormwater treatment systems, excess flows from infiltration systems, and wetlands, ponds and swales.
