Sanitary Structures

Sanitary sewers are used for the conveyance of sanitary sewerage intersections and clean-out points. Design Precast & Pipe, Inc. offers a full line of sanitary sewer components ranging from small diameter manholes to large diameter round and square lift stations.

We also offer precast concrete inverts or flow channels to eliminate the need to precast these in the field.
