South Boulder Diverter

South Boulder Diverter


Located in Eldorado Canyon, the South Boulder Diversion Structure channels water into Denver Water’s treatment system. Constructed over 75 years ago, this site was due for some rehabilitation, including the application of industrial coatings.

About the Project

Due to Denver Water’s storage and capacity needs, a rigid schedule was set for this project. Three periods were initially identified during which the water levels at the Diversion Structure could be lowered.  Accessing the Diversion Structure on the one-lane road through the Canyon proved difficult and site staging was an element of the project that had to be carefully considered by Coblaco’s Operations team in order to effectively position the large equipment required.

Full containment and dust collection would be needed for surface prep on the largest and most complex components of the Diversion Structure.  The two trash racks and two tainter gates receiving coatings were complicated structures with edges and angles that commanded a diligent use of good painting practice in order to coat adequately. Dropping temperatures forced the use of tarps, reinforced scaffolding, and heaters to ensure proper application conditions.

Top-coat application was conducted using plural component equipment.   Despite the difficult conditions and complex nature of the project, Coblaco was able to complete all of the work requiring within two shutdown periods, making a third shutdown unnecessary.
