Globe-Style Silent Check Valves

Pump Station Check Valve Basics

Check valves are an important component of any lift station design. Without check valves, the pumps and wet well of a lift station can be subject to damage from backflow. Backflow occurs when the lift station pumps stop operating and the water in the force main and discharge piping flows back into the wet well. In virtually every case, the backflow creates high levels of hydraulic pressure that pumps and wet wells are not designed to handle. The solution is a check valve. This simple device is available in several models and configurations and each variety can impact the design and cost of a lift station system.

Jockey Pumps used in a Stormwater Pumping System

Part Six: Praxair Hydrogen Refinery in Port Arthur, Texas

In part six of this industrial stormwater blog series, Romtec Utilities worked with Praxair, Inc. and S & B Engineers and Constructors on another addition to a Valero Refinery, this time in Port Arthur, Texas. This project provides an opportunity to demonstrate how Romtec Utilities can design for precise pumping goals when the criteria for stations are essentially the same but with crucial differences.
