Yocha Dehe Wintun Nation – Wastewater Pump Station
Wastewater Pump Station Project Description
The Yocha Dehe Wintun Nation is a self-governed nation that takes pride in their heritage. As part of the native inhabitants of California’s Capay Valley, this tribe honors their ancestral Patwin language in their name with Yocha Dehe translating to “home of the spring valley”. After receiving ancestral lands back, the Yocha Dehe Wintun Nation established the foundation for their tribal government and the Cache Creek Casino Resort.
The Mossy Creek project is a wastewater lift station for a new development to support the Cache Creek Casino Resort. Located off of Highway 16 in Brooks, California, this project was brought to Romtec Utilities by Laugenour & Meikle, the Engineer hired by the Yocha Dehe Wintun Nation.
This new development is largely in part to a growing population and need for residential dwellings. The existing infrastructure could not support the additional homes and commercial locations. With the addition of the Mossy Creek system, the current development and future developments will be properly supported. The Yoche Dehe Wintun Nation collection system then pumps to the on-site treatment plant owned and operated by the casino resort.
Wastewater Pump Station Design
This Romtec Utilities supplied wastewater lift station features a pre-cast 6’ inner diameter (ID) wet well that is 26.66’ in depth. Two 23 horsepower (HP) Flygt submersible pumps sit at the bottom of the wet well, and will be controlled by an Allen-Bradley CompactLogix Controller.
The controller in this system will receive level readings from a Versaline VL2000 pressure transducer. In the event of failure of the pressure transducer, two NOLTA MS1 Floats will work as backup level sensors.
In addition to the wet well, Romtec Utilities also supplied a stainless steel disconnect stand for this project. Disconnect Stands can be an important safety feature for a lift station. Gasses from the wet well can be combustible, and placing the electrical components out of this “classified” space (where gasses can be high in concentration) reduces the risk of dangerous incidents. They also allow for easier connection of the electrical components in the wet well and easy visual inspection for cables.
The Mossy Creek lift station disconnect stand includes Meltric Decontactors. These decontactors include self-contained plug contacts that resist arcing, making them a safer option than normal connectors. Meltric Decontactors provide safety precautions while also making pump maintenance faster and easier. These disconnects can be unplugged and plugged-in in a matter of seconds, and remove the need for a certified electrician.
Romtec Utilities supplied this lift station and the components to the contractor, Pacific Utility Construction, for the installation of the system. The completion of this project will allow the Yocha Dehe Wintun Nation to move forward with construction of the new development and bring even more resources to the native community that they help support.
