Omega Mine extends AMD treatment capacity with dewatering
At Omega Mine in West Virginia, GEOTUBE® GT500 units help the West Virginia Department of Environmental Protection treat and dewater acid mine drainage from abandoned mines while supporting long-term capacity and compliance.
Dredging and reuse of contaminated sediments
Embraport used dewatered contaminated sediments as structural fill within its terminal platform, saving 400,000 m3 of imported material and reducing earthfill platform costs by 20% to 30%.
Lake bank stabilization at Vivid Shores
At Vivid Shores in Bonita Springs, Florida, PROPEX® Armormax®, MIRAFI® FW403 and MIRAFI 140N stabilize lake banks exposed to wind-driven wave erosion. Completed sections are performing as designed.
The Mayo Clinic Hospital, Phoenix is located within the southernmost portion of the Desert Ridge Master Planned Community. Early USACE permitting required wash corridors within the community to remain natural. Construction of the Mayo Clinic Phoenix Campus began in 1996. Prior to development, the City of Phoenix required a corridor be designated along the eastern boundary of the Campus for construction of a regional drainage channel. This channel would protect the eastern portion of the Campus from offsite flows. The entire project lies within the FEMA defined alluvial floodplain FEMA Special Flood Hazard Area.
In 2005 an Individual 404 Permit was issued by the USACE for the entire Campus, allowing disturbance to jurisdictional washes located on the Campus. Conditions of approval required reconstructed wash corridors to be revegetated.
Recent development along the eastern side of the campus required the construction of drainage improvements. A new channel was tied-in to existing culverts below the 101 Loop and then routed down gradient between buildings on the eastern portion of the Campus.
The channel section is designed to have a meandering, low-flow channel section to match the existing wash bank’s full capacity. The 100-year design worst-case flow of 66 m³ (2,338 ft³) would overtop the low flow banks and be contained in the flood flow channel.
To protect the outer banks of the flood flow channel from erosion, promote natural vegetation per the USACE permits requirements, and accommodate desert landscape plantings, the design engineer chose PROPEX® Pyramat®.
PROPEX Pyramat is a High Performance Turf Reinforcement Mat (HPTRM) that protects the ground surface from erosion while promoting natural vegetation. Due to its homogenous structure, PROPEX Pyramat can be cut to accommodate landscape plantings for aesthetics. PROPEX Pyramat 75 is an approved material for privately owned channels within the City of Phoenix.
After PROPEX Pyramat was installed, it was soil filled and hydroseeded with native seed mix. The installed nature-based solution meets the USACE permit requirements and required no revisions to the FEMA Flood Insurance Rate Map (FIRM).
