OFWD Three Rivers Hatchery Weir Drainage Improvement

Increased resilience of concrete abutment, alleviating the hydrostatic pressure exerted by water on the concrete weir. Learn how OFWD Three Rivers Weir achieved precision with JET Filter solutions.

Drainage Dillema

In Hebo, Oregon, the OFWD Three Rivers Weir improvement at Cedar Creek Hatchery embarked on a vital mission to enhance the resilience of a concrete abutment for the weir by focusing on hydrostatic water pressure relief. Led by the Oregon Department of Fish and Wildlife, this collaborative effort with MJ Hughes Construction was designed to address a critical concern— alleviating the hydrostatic pressure exerted by water on the concrete weir.

Solution

The Oregon Department of Fish and Wildlife’s (ODFW) weir project exemplifies the integration of innovative, sustainable practices in infrastructure development, particularly through the implementation of the JET Filter system. At the core of this project’s success is the JET Filter’s two-stage filtration design, a feature that has significantly contributed to the project’s sustainability goals by facilitating effective drainage without soil loss.

The JET Filter system, with its 316/316L stainless steel housing, was chosen for its durability, maintainability, effective drainage, and minimally invasive installation process (approximately 30 minutes per unit.) This aspect was crucial for the timely and cost-effective completion of the ODFW weir project, demonstrating a pragmatic approach to infrastructure development.

Moreover, the maintainability of the JET Filter system stands out as a pivotal feature for the weir project. Its design not only addresses the immediate needs for effective drainage but also ensures long-term operability and ease of maintenance. This is particularly important for the ODFW project, where the ongoing functionality of the weir is vital for the conservation efforts and the management of aquatic ecosystems. The project serves as a beacon for sustainable construction practices, showcasing how innovative drainage solutions like the JET Filter system can be seamlessly integrated into infrastructure projects to achieve environmental sustainability, operational efficiency, and economic viability.
