Lake Fork Pump Station was a City of Dallas Texas Water Utilities Department Project. The project was located along the shoreline of the Lake Fork Reservoir near Dallas, TX. The excavation utilized a combination of open cut from + - EL 404 to a 25ft wide bench at EL 376; then the Contractor installed a perimeter steel #sheeting system that was + - 350ft x 150ft.
Batchtown Wildlife Refuge Rehabilitation, St. Louis, MO
Deep well dewatering system for the Batchtown Wildlife Refuge Rehabilitation project near St. Louis, Missouri. The wells were installed on a oval earthen berm directly in the Mississippi River. Individual wells were pumping roughly 1750 gpm each.
Eppley Airfield, Omaha, NE
Installation of seventy (70) relief/dewatering wells to aid in flood mitigation at Eppley Airfield in Omaha, Nebraska. Wells were drilled to a depth of 90’ below grade using a 30” diameter borehole, setting 12” diameter PVC screen and casing. Wells were drilled with bucket auger drilling method. Wells were developed, pump tested, and checked to assure sanding rates less than 5 ppm. Due to piezometric level above existing grade, all wells drilled from pads 10’ to 12’ above existing grade.
Engineering & Design Services
Griffin’s purpose is to provide the most cost effective groundwater solution available for each project. The most efficient groundwater control system can be designed when Griffin get involved in design process to gather data and understand the local hydrogeology. Working closely with project engineers and architects in design process can help to develop a sound approach for groundwater issues based on the project constraints.
Lake Isabella, Bakersfield, CA
Dam Flow Aided by 200,000gpm Griffin Pump Station. To accomplish this project, Griffin outfitted the pump station with fifteen 24 inch axial flow pumps and two 36 inch Diesel Driven mixed flow pumps. Griffin's 24AX Hydraulic Submersible Pumps are each capable of pumping 20,000gpm. The project was on Lake Isabella in the desert mountains above Bakersfield, California.
Griffin Non-Clog Pumps
Griffin non-clog pumps featuring a non–clog impeller capable of handling solids up to 4 1/2” and a large clean out port for hassle-free removal of large debris over 4 1/2” without removing suction pipe or hose.
Sewer Bypass Pumping
Griffin was called by TLC Plumbing in Albuquerque, N.M., to look at a site where a 54-in. sewer line had collapsed. The collapse had resulted in a major intersection in Albuquerque to be closed and sewage to overflow. TLC had worked to contain the situation, but in order to make the repairs realized, bypass pumping by Griffin was required.
