WACO Products Inc.

WACO Products Inc. is a Baltimore, Maryland-based manufacturer with over 50 years of experience designing and fabricating engineered aluminum and stainless steel structures for municipal water and wastewater treatment facilities. The company holds ISO certification and operates across three divisions—Marine, Environmental, and General Fabrication—serving industry and government clients globally. Within the water and wastewater sector, WACO’s Environmental division produces seven distinct product lines, all leveraging aluminum’s natural corrosion resistance, light weight, and strength. Slide Gates feature 1/4-inch aluminum slide plates with Poly-Glide UHMW polymer bearing bars integrated into extruded frames, available in handwheel or electric motor configurations with optional neoprene P-seals for reduced leakage. Weir Gates control flow through port openings and balance flow across parallel treatment channels by adjusting the slide plate height. Barscreens intercept coarse debris at treatment plant headworks to protect downstream equipment, with adjustable bar spacing and companion rake systems. Debris Baskets protect lift pumps at pumping stations, offered in coarse or fine configurations with extruded guide channels that double as access ladders. Stop Gates provide economical flow control with optional V-notch, rectangular, or proportional weiring cutouts for flow measurement. Duralite Stop Logs shut off flow through channels in 8-inch height increments with integral reinforcement to withstand hydrostatic loads and neoprene perimeter seals. Vertical Ladders provide access into underground pump stations with non-slip rungs and optional fall protection harness systems.
