GP HydraFlow Drop Boxes
Lower the buildup of heavy solids and grease on lift station walls up to 95%!
Compact design can fit in any lift station or manhole
Drastically reduce the maintenance costs of your lift stations and manholes. These patented drop boxes lower the buildup of heavy solids and grease on the walls by as much as 95%. They also reduce odors and H2S gas buildup, minimize corrosion and eliminate the need for chemicals.
Drop boxes discharge wastewater along the interior wall of the lift station, which causes the wastewater to flow in a circular direction. This circular flow moves the solids, reducing their tendency to float and collect on the water surface. Gravity and the force of the effluent’s own flow rate power this cyclonic action, so no electrical connections are needed.
Drop boxes are constructed of heavy-gauge 316 stainless steel, and are easy to install. They fit any lift station or manhole with at least 36" of space between the bottom of the inlet pipe and the top of the effluent level. Custom sizes available as special order.

Note: PVC drop pipe and 90° elbow not included. Add your own based on your specific needs.
