Sewer Manhole Replacement
Project Owner City of Wichita Project Delivery Method Lump Sum Completion Date / Total Time for Project November 2016 / 10 Weeks Project Value $1,200,000

Project Overview

UCI was contracted to remove and replace an existing sanitary sewer manhole in the main line for the City of Wichita. Influent and effluent pipe to the manhole was 78” diameter and approximately 23’ deep. The project required 28,000 gpm of bypass pumping 300 feet away for a period of 41 days. What made the project unique was the existing MH was underneath the I-35 interstate and the new MH was very large, 12’x8’ box with 1’ thick walls weighing over 40,000 lbs. Careful thought and thorough planning went in to safely installing the MH with the limited headroom available. Also, because the MH was in the middle of an existing main thoroughfare, open cutting the excavation was not an option. Instead UCI installed an engineered system of auger cast piles and steel beams to create the excavation. To tie the sewer system back together, UCI wire saw cut the existing pipe back from the MH and cast-in-place two sections of 78” concrete pipe ‘shoulders’.
