Shoal Creek Wastewater Treatment Plant
Joplin, MO
Background
Growth on the south side of Joplin overloaded the outdated original Shoal Creek WWTP. The City needed a new treatment plant. In the mid-1980’s, the Shoal Creek Wastewater Treatment Plant was relocated to a new site southwest of Joplin. Allgeier Martin AMA designed for the construction of a new facility with a 6.5 MGD average flow and 15 MGD peak flow. The plant needed more capacity for biological treatment and sludge handling. This was due to stricter regulations.
Activity
The City again looked to Allgeier Martin to plan and design this relocated wastewater treatment plant. In 1988, the Shoal Creek Wastewater Treatment Plant (WWTP) was constructed and put into operation. Once the regulations on BOD and suspended solids tightened, Allgeier Martin was again hired to plan and design improvements in 2010.
As part of the 1988 project, approximately 4 miles of gravity sewer and 2.4 miles of pressure sewer were constructed. The system includes three flow equalization basins that allow for cost-effective design, construction and operation.
