Best Practices to Manage Effects of Settlement and Heave at Catch Basins and Manholes

Status:  Active
Project Start Date:  04/17/2019


Other than an outdated Minnesota study on manholes from 2001, which doesn't address catch basins, very little documentation exists on the Minnesota municipal experience with catch basins and manholes, nor the municipal experience in the United States. Most publicly available resources on manholes and catch basin installation are promotional literature or articles from industry publications. To address this need, this project will produce a resource that (A) discusses installation techniques that prevent settlement or heave near catch basins and manholes, (B) documents the experiences of Minnesota municipalities with catch basins and manholes, and (C) documents available catch basin and manhole products.
