jweddell500gpm - 1,000gpm, Central, Mixed Use Development, Resorts/ Golf Courses, Wastewater

A residential boom town of employees from nearby natural gas mining facilities needed a large lift station to handle over 1.2 MGD of wastewater. Submersible Ebara sewage pumps in a triplex configuration were included for the new and future pumping rates resulting from residential growth. The lift station controls are located in a nearby control building. The UL listed control panel utilizes floats for primary and backup level controls, an autodialer for communications, and a permanent onsite generator for backup power.

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.
