Truckee Meadows Water Authority – Wastewater Lift Station With Drop Bowl Assembly
The Mt. Rose Pump Station is a wastewater lift station in Reno, Nevada. This project was brought to Romtec Utilities by Stantec to develop the scope and configuration of the lift station. Ultimately, Romtec Utilities was used as the basis of design. At the time of bid, Romtec provided this complete pumping system to the contractor, KG Walters, and to the Truckee Meadows Water Authority.
This project features a 5’ inner diameter (ID) wet well that is 13.66’ in depth with two 2 horsepower (HP) Ebara submersible pumps, which will be activated by an alternator relay when the level sensing devices send the signal to start or stop pumping out the water.
Wastewater enters the well through inlet pipes that feed into a drop bowl assembly. Drop bowl assemblies catch the incoming water and feed it downwards, reducing the amount of turbulence in the water and protecting the components in the wet well by ensuring that they do not get moved out of position by the flowing water.
While some components in the wet well are heavier and less susceptible to movement, components such as pump cables or level sensing devices are more likely to be jostled by flowing water. Floats, like the four NOLTA MS1 floats used in this system, are sensitive to movement and trigger the pumps when the water gets high enough to tip the float. Drop bowl assemblies are an easy and cost-effective solution to reduce turbulence in a wet well, and the Mt. Rose lift station will benefit greatly from its addition to this project.
Stantec, KG Walters, and Romtec Utilities were able to come together and provide a system that would meet the needs of this pumping station for the Truckee Meadows Water Authority. It was a pleasure to work with these agencies on this project.
