Influent Pump Station Rehabilitation Study
Influent Pump Station Upgrade
Detailed Design and Implementation

Stone Environmental was contracted to review data and propose improvements to upgrade the influent pump station at the Indian Lake WWTP in Russell’s Point, Ohio. The pump station did not include pretreatment (screening or grit removal) and the pumps were constantly clogged, requiring excessive maintenance. Stone Environmental evaluated new pretreatment equipment as well as new “chopper” pumps for use. Capital and operation and maintenance costs were estimated in order to develop life cycle costs for the upgrade. Stone Environmental prepared detailed construction drawings of the approved upgrade, and Ohio EPA permit-to-install application for the replacement of two raw sewage pumps with “chopper” pumps and a sluice gate at the Indian Lake wastewater treatment plant
