DRAINAGE SYSTEMS

Our commitment to providing stormwater management solutions for every environment and need has led to the development of superior quality drainage products for a wide variety of residential and non-residential systems. Please see the product sections below for further detail about each component.


FLO-WELL

Our Flo-Well units collect, retain, and discharge stormwater on-site, with each unit holding up to 50 gallons of stormwater. A gravel-free alternative to a traditional dry well.

  • Applications: surface or subsurface drainage
  • Load rated: up to Class B with appropriate grate

SABER PIT

The Saber Sump Pump Pit and Saber Tank Extension are molded from high quality, impact resistent polyethylene. This tough, seamless, corrosion proof construction together with the system's innovative patented design and proven capabilities has set the standard for the future in drainage. Poor drainage and expansive soils are a global concern. Annual repair costs to man made structures exceeds $100 billion dollars in the United States alone. Saber Drainage Systems has targeted each area where conventional drainage methods have failed, identified related problems and designed a solution. The Saber Sump Pump Pit will not fail under soil shifting or ground heaving conditions. The Saber Sump Pump Pit reduces soil moisture content because it is a subsurface drainage system.


STORM WATER MANAGEMENT

StormTech chambers are cost-effective subsurface storm water management solutions and an excellent alternative for Retention/Detention systems. The chambers are carefully engineered to meet the demands of subsurface storm water management applications.

StormTech chambers offer versatility to the design engineer, are lightweight and have secure overlapping joints. The open bottom chamber can be used for retention where storm water infiltrates into the underlying soils or for detention where peak flows are attenuated using an outlet control structure.


TRENCH & CHANNEL DRAIN

Trench and Channel Drain Systems provide durable and proven solutions for perimeter drainage in applications ranging from light foot traffic to heavy vehicular traffic.

  • Applications: surface drainage
  • Load rated: up to Class D with appropriate grate

DRAINAGE PIPE

We carry corrugated high density polyethylene pipe, single wall and N12; all available in different sizes. HDPE pipe is the preferred choice due to its durability and high resistance to corrosion and chemicals.



EZFLOW

EZflow offers a sustainable and gravel-free alternative to a traditional French Drain system, and takes less than half the time to install.

  • Applications: subsurface drainage
  • Load rated: up to H-10 when following specific installation guidelines

TRIPLE WALL HDPE PIPE

TRIPLE WALL HDPE PIPE is triple bonded polyethylene for exceptional pipe stiffness. With smooth inner and outer walls and a corrugated structural core, Triple Wall pipe is designed to have superior pipe stiffness to that of PVC sewer and drain pipe


SINGLE WALL PIPE

SINGLE WALL corrugated HDPE pipe is ideal for drainage projects where flexibility, light weight and low cost are important

Straight and coil pipe are available


N-12 DUAL WALL PIPE

N-12 is the world standard for corrugated polyethylene drainage pipe. 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. 


SEWER & DRAIN FITTINGS

Our comprehensive line of sewer and drain fittings include valves, couplings, and connectors in PVC and styrene. To see the full range of products available, click on the product links below.


SOLVENT WELD FITTINGS

  • Product specifications: 02535 Flexible Saddles

CATCH BASINS & GRATES

We offer a complete line of catch basins and grates for residential and non-residential stormwater management solutions. Catch basins have a sump area that collect debris and prevent clogging of the pipeline, and grates are available in a variety of colors to blend in with surrounding surfaces. Depending on the size of the round, square, or atrium grates, they may fit directly into a riser of pipe, sewer and drain fitting, or our catch basins.


SQUARE CATCH BASINS

Our famous catch basins and grates range in size from 9" square to 24" square.

  • Black, gray, green HDPE grate options
  • Galvanized steel, cast iron, manganese bronze grate options
  • ADA Compliant & Heel Proof options
  • Install with proper grates for traffic rated areas

ROUND SPEE-D BASINS

Use our compact 6" round Spee-D basins to collect runoff water while its sump area collects debris and prevents clogging.

  • Black HDPE
  • Use with grates or Pop-up Emitters

POP-UP EMITTERS

Our Pop-Up Drainage Emitters are a safe and effective way to discharge water from a drainage system.

  • Applications: surface drainage

SQUARE GRATES

Our Square grates and adapters are a perfect fit when the need for a catch basin is not necessary.  Connect these grates directly to pipe or fittings.

  • Available in green, gray, black, or sand HDPE

PERMEABLE PAVERS

Permeable Pavers are a sustainable alternative to traditional paving methods. By providing a permeable surface in place of impervious hardscaping and allowing water to filter through to the subsurface,  Permeable Pavers reduce runoff and allow stormwater to be processed on-site. The final area looks identical to regular turf or a gravel road, but can support anything from heavy vehicles, such as a fire truck, to daily vehicle parking.
