Project Description

To address the industrial stormwater concerns of coastal Louisiana, this large, precast concrete pump station was designed to meet super-high flows of runoff at this Exxon refinery. Five vertical turbine pumps and three submersible pumps, capable of pumping 60,000 GPM, are spread across three large interconnected rectangular wet wells. This approach was much more affordable than a single poured in place sump, and the connection tubes make the functionality near identical. A robust steel baffle slows incoming stormwater at the inlet line to reduce turbulence and wear on the sump components.

Why They Chose Romtec Utilities

Exxon Mobil and Chalmette Refining, LLC possessed an existing stormwater pump station with a large rectangular concrete sump that required replacement. The existing pump station location made the excavation for a new pump station impractical and expensive. They developed a plan to prefabricate a new concrete sump that would “fit” inside of the existing wet well. Romtec Utilities was contacted as the package lift station engineering firm with the necessary expertise to design, manufacture, and supply the complete lift station components. To achieve maximum cost effectiveness, Romtec Utilities supplied three prefabricated concrete wet wells that were “tethered” together. Exxon Mobil and Chalmette Refining were able to then back fill the abandoned sump for a pragmatic and cost effective stormwater solution.
