Marana Regional Airport. Fire Suppression Pump Station.
Design of a fire suppression systems including pump house, water supply wells, 1.5 million gallon steel storage tank, 3 miles of pipeline, hangar sprinkler systems, and runway fire hydrants. Construction plans, specifications and cost estimate.
San José silver mine. Water supply studies.
Water supply study for a proposed silver mine. Project included regional water availability survey and the preliminary design of five supply options encompassing new reservoirs, 70 mile long supply pipelines and connections to existing public infrastructure. Developed alternatives analysis and option selection matrix.
Prepared analysis of flood control and drainage diversion options for regional drainages to allow mine expansion. Project included the elaboration of preliminary construction plans and the related costs of all the drainage diversion options encompassing different configurations of channels, tunnels, culverts, and dams.
Guenacevi underground silver mine dewatering
Design of dewatering system for underground mine including three pump stations and the preparation of preliminary construction plans and specifications. Each pump station consisted of three high lift and high capacity pumps (1,800 gpm with 350 feet of lift) with 500 hp electric drive motors including related manifold and pipelines for dewatering 3 different ore bodies in an underground silver mine.
Geotechnical studies to determine options for seepage control at the pit crest. Work included geotechnical drilling, sampling, geotechnical and geochemical testing of mine waste rock dumps and natural soils.
Design and preparation of construction drawings of six (1 acre) lined reservoirs to intercept surface water and limit groundwater recharge from rain and snow.
Peñasquito Mine. Design of HDPE pipeline.
Project Manager and engineer. Design and preparation of construction drawings for 12 mile long collector pipeline for 8 pit dewatering wells, including hydraulic analysis of the interconnected well pump network with numerical simulation software (Water Cad).
Peñasquito Mine. Pump station design.
Project manager and engineer. Design and preparation of construction plans and specifications for a 2,000 gpm pump station, including staging reservoir. Design included hydraulic analysis with numerical simulation software of the interaction of the pump station discharge since it is connected to the plant's pressurized main supply pipeline.
