Sewer Manhole Rehabilitation

Project Description

As is common for older cities in Arkansas, many of the original manholes in Pine Bluff were constructed of brick. Over decades of use these manholes begin to leak and may even fail structurally. This project included the rehabilitation of 17 manholes with a cementitious and epoxy liner. The cementitious liner restored the structural integrity of the manholes and sealed out infiltration. Epoxy was applied to protect the cementitious liner in manholes where significant corrosion was known to be an issue. Hawkins-Weir Engineers provided the preliminary and detailed design services for this project along with administration and inspection during construction. Due to various Utility budgetary concerns and the need to conduct these types of improvements during warmer weather, Hawkins-Weir Engineers had a very short timeline to complete this design work but met the challenge and had the project ready to advertise in less than three weeks.
