McNeill Water & Wastewater, Inc., manufactures precast concrete hoppers for installation in clarifiers and other applications. The precast hoppers save time and the difficulty of forming hoppers in place.

The hoppers are cast of 4,000 PSI, 28 Day Concrete, using Type II Cement. Each unit has reinforcing dowels protruding around the upper perimeter to allow proper connection to the poured in place foundation slab to surround each hopper.

Precast concrete hoppers are available in the following sizes:

• 5'-0" x 5'-0"
  
• 6'-0" x 6'-0"
  
• 7'-0" x 7'-0"
  
• 8'-0" x 8'-0"
