BILCO Roof Hatches Help Protect Pumps from Ravages of Flooding

 

Project Snapshot

• Missouri American Water completed a new pump station at its South Plant Intake Center to protect critical infrastructure from flooding along the Meramec River.
• The two-year project delivers raw water to Missouri American Water’s South Plant, serving residents in St. Louis County and parts of St. Charles County.

• The project included stainless steel BILCO roof hatches with integrated pulley systems, allowing floor-level access for maintenance and replacement of six vertical turbine pumps.
• A large BILCO floor door with fall protection grating was also installed in the pump room to provide safe access where water intrusion is a concern.

Flooding along the Meramec River repeatedly overwhelmed Missouri American Water’s existing South Plant Intake Center, submerging pump motors and disrupting operations. To address the issue, Missouri American Water invested in a new pump station designed to keep critical equipment well above the 500-year flood level while continuing to supply raw water to the South Plant.

The new intake structure rises 45 feet above grade and extends 45 feet below grade to maintain submerged intake screens. The facility houses six vertical turbine pumps and incorporates BILCO roof hatches and a floor door to provide safe, efficient access for maintenance and long-term operation.
