Joplin Creek Interceptor Sewer Replacement

One of the City’s oldest sewer sections, along the north end of Joplin Creek, was too small for the area’s growth. It was also deteriorating. Additionally, the interceptor sewer was constructed of concrete pipe with brick manholes. These assets were deteriorating, and defects were allowing large volumes of inflow and infiltration (I&I) to run into the sewer system. The I&I caused hydraulic issues at the Turkey Creek Wastewater Treatment Plant. The City required an engineer to plan, design, bid, and inspect construction of a replacement sewer interceptor.

The City hired Allgeier Martin (AMA) to plan and design the new sewer interceptor with associated manhole renovations. The project site is generally East of Lone Elm Road, along Joplin Creek and West of Dover Hill Elementary School. The contract includes bidding services and Resident Project Representation for construction inspection. The Joplin Creek interceptor sewer was a parallel system with one newer large diameter and one older small diameter sewer line. AMA evaluated different options for improvements and expansion of design capacity. The team determined the design should incorporate the newer large interceptor sewer line. A new larger diameter interceptor would replace the parallel smaller line.
