Siamese/Stortz Manhole

Our Siamese/Stortz Manholes are complete with the floor drain, boots and/or pipe gaskets for pipe, o-ring for joint, and Neenah R-5900-F frame & lid cast into our flat slab top. We  can quote and build custom engineered valve vaults that meet the engineers' specifications or we  can design and submit an alternate design for approval. We have worked with various city, county, state, and federal agencies and can assure that our product designs meet the various requirements and regulations.
