R.W. Beck- San Diego County Water Authority

The Lake Hodges Pipeline and Hydro Electric Pump Station is a part of San Diego County Water Authorities Emergency Storage project. Hydraulic turbines will provide the additional benefit of capturing energy created when water flows from the Olivenhain Reservoir into Lake Hodges. The pump station will generate 40 Megawatt capacity by utilizing 2 each 20 MW (15300 HP) vertical generators. This very important project will increase the amount of water available within the county for use during emergencies. The work being performed consists of the construction of new pump station and inlet outlet structures, installation of fabricated steel pipe and fittings, and related systems, gates and valves, and other appurtenances.

ON-SITE provided shop fabrication inspection services of the mechanical equipment and large diameter steel pipe and fittings associated with this project at various locations both domestic and China, Brazil, and Canada.

Richard Brady-San Diego County Water Authority

Rancho Peñasquitos Pressure Control and Hydroelectric Facility located in the Mira Mesa area, will serve an important function in improving aqueduct operations and enhancing the flexibility of the Water Authority’s extensive water delivery system. A 4.5-megawatt hydroelectric turbine generator will generate supplemental electricity in the facility and will operate year-round, reducing the Water Authority’s energy costs while supplying surplus power to the region. The construction of this $21 million facility consisted of the manufacture of 3,000-feet of 96 inch-diameter and 108-inch-diameter pipe at numerous locations throughout Korea that will connect the facility to existing pipelines.

ON-SITE provided inspection of the large diameter pipe, fittings and coating inspection at locations throughout Korea and the United States. Fabrication inspection of the engineered equipment such as the pumps, valves and turbines will be inspected at various worldwide locations

City of Tacoma Department of Power Mossyrock Unit Rebuild

The Mossyrock Dam and its Two-200 Mega Watt generator units were commissioned in 1968 and are part of Tacoma Power’s largest Hydroelectric electricity generating facility that generate about 3 billion kilowatt-hours of electricity each year. The powerhouse contains two generating units and has a total installed capacity of 300 MW. The 2 generating units account for 40% of the Cities power generating resources and have been in service for over 40 billion kilowatt hours. Tacoma power started a project to rebuild these units to increase efficiency with an estimated cost of $50M. As an owner representative

ON-SITE provided shop fabrication inspection services of the mechanical equipment involving the Francis Turbine runner replacements (200 MW and 175 MW capacities), Turbine wicket gate replacements. This project was being manufactured at numerous locations including India.
