HARCO surface drainage structures, including drain basins and inline drains, are manufactured from PVC pipe stock utilizing a thermo-molding process to ensure consistent watertight seal throughout the structure body and the outlet stubs. The raw material used to manufacture this PVC pipe stock shall
conform to ASTM D1784 cell class 12454. These heavy-duty PVC structures are abrasion resistant and virtually immune to most types of corrosion.
Every drainage system is different. Whether small or large, your drainage system may require adapting to multiple pipe types and diameters, changes in direction and elevation.
HARCO Drain Basins are custom built in a timely manner for each individual project, ensuring you can meet the design and timeline requirements for your project.
Your are here:
are used at the beginning of a drain line and when adding a new water inlet to an existing
drain line using a riser pipe and tee.
are used as a junction box when drainage system inlets
/ outlets change diameter, change pipe type, change elevation, change direction, and allows for multiple inlets or outlets in one
structure and for a water inlet and sediment collection point entering a drainage system.
The outlet stubs
for HARCO surface drainage structures are manufactured from PVC pipe stock utilizing a thermo-molding process to ensure a tight pipe-to-structure
fit that can meet or exceed the pressure requirements of the ASTM D3212 standard for connections joining drainage pipes utilizing
flexible elastomeric seals conforming to ASTM F477.
HARCO Surface Drainage Structures are a perfect choice for:
• Commercial Developments
• Schools and Sports Complexes
• Roadways and Highways
• Parking lots
• Government Installations
• Parks and Recreation Areas
• Industrial Parks
• Golf Courses
• Residential Developments
HARCO plastic surface drainage structures should be installed following the same ASTM D2321 installation guidelines accepted for backfill, compaction and installation of plastic drainage pipes.
HARCO can provide connections to most corrugated and smooth-wall plastic pipe types/brands.
