Gunderboom Now:Where We Are Today
• Strategically Aligned With:• PND Engineers, Inc.• HDR/LMS• Pipeline Systems Inc.
Innovative Design and Engineering - 1
• Gunderboom always considers– Target Species– Nature and degree of contamination &
concentration of suspended solids– Water characteristics
• Flow rate• Currents• Wave height
• Gunderboom always considers:– Seasonality– Degree of automation– Physical factors
• Bathymetry• Bottom conditions• Configuration of water body

Gunderboom Applications
Marine Life Exclusion System (MLESTM)Reservoir Protection System (RPSTM)Particulate Control System (PCSTM)Sound Attenuation System (SASTM)Beach Protection System (BPSTM)
Marine Life Exclusion System(MLES)
• The Solution to 316(b) Issues– Reduces impingement and entrainment
by excluding:• Planktonic fish• Fish Eggs• Larvae• Vegetation• Debris• Other Swimming Organisms
System to
minimize ichthyoplankton entrainment and impingement.
MLESProven Technology
MLESMeasurable Results
90% and higher exclusion while maintaining intake approach velocity of
0.012 fps
Reservoir Protection System(RPS)
• Affordable, durable, easy to deploy and maintain– Filters suspended solids 10 microns or
smaller– Creates areas for settling– Protects drinking water from:
• Particulates• Contaminants• Pathogenic microbes
• The RPS has achieved successful reductions for drinking water.
• Reductions:– TSS: 93%– Turbidity: 96%– Coliforms: 99%

Caltrans Pile Driving Installation Project (PDIP)Location: Oakland Bay, Calif.
Problems:• Concussive force of
driving 8 ft diameter piles deleterious to fish populations.
• Damaging affects occur at 190 dB for marine mammals, fish, as low as 170 dB for fish with swim bladders.

HEAVY DUTY TURBIDITY BARRIERSpecification:“A. Silt/turbidity barrier shall consist of heavy duty non-woven skirt, flotation elements, PVC coated reinforced vinyl debris boom, top tension cable and bottom chain ballast or other anchorage system which will not obstruct navigation.B. Barrier shall be full-height, extending from the water surface to the river bottom. The height will depend on the alignment of turbidity barrier and the bathymetric contours along that alignment.C. Non-woven skirt shall be comprised of 100% polypropylene filaments, needle punched and heat set.” “Gunderboom or equivalent”
