Iowa Storm Catch Basins / Manholes

Hancock specializes in producing custom structures for both storm water management and sanitary sewer systems taking a proactive approach to ensure the project plans and specifications are translated precisely into the finished concrete structures. We manufacture large complicated structures but also hold true to the basics: from large box manholes, lift stations and massive round manholes to basic area intakes, curb inlets and standard 48” manholes.

The precast industry continues to innovate, especially in the area of structures. Our expertise in applying new concepts and designs means we always like a good challenge in finding a precast solution. With superior strength and durability, precast concrete manholes and structures provide a versatile and economical alternative to cast-in-place concrete and other materials.
