The Los Angeles Reservoir Ultraviolet Disinfection Plant (LARUV) has a maximum treatment capacity of 650 MGD, multiple backup power supplies, 3-leg flow control station, flexible trunk line joints, ultraviolet system, underground chlorine injection vault, and a network of controls and mechanical systems.
From a project management perspective, this was a massive undertaking. The project team used Navisworks to identify construction conflicts during design. They managed five different contracts, tracked approximately 27,000 activities on Primavera 6, installed more than 740 pieces of equipment and 600 valves and laid almost 118 miles of conduits. The team additionally conducted more than 440 loop tests, performed 21 different field acceptance testing scenarios, and held over 1,000 project meetings. As a result of the project team's efficiencies, the $123 million facility is one of the most cost-effective UV treatment facility projects in the nation, according to the project owner.
