Water Treatment Facility Improvements
Coffeyville, KS
Background
Coffeyville’s 7-MGD Water Treatment Plant needed repair and improvements. The facility was outdated and no longer ran at full capacity. An engineering firm was required to design improvements to get the plant operating efficiently again.
Activity
Allgeier Martin was hired in 2001 to design major facility renovations. In 2009, Allgeier Martin was again hired to design, administer, and inspect additional improvements. A number of waterline stops and valve replacements were needed. A video surveillance system was needed for increased security. Allgeier Martin’s construction estimate greater than the actual construction cost. The surplus allowed Coffeyville to add cleaning and disinfection of a water tank, and an additional waterline stop to the project.
In 2018, Allgeier Martin completed design for the renovation of a sixth filter to bring the plant’s capacity to 8.44 MGD. The control panel and SCADA system were updated to include the controls for this filter cell.
