Davis Water Treatment Plant


The City of Austin currently has three water treatment plants, Water Treatment Plant 4, Davis and Ullrich, which draw water from the Colorado River and treat it to drinking water quality. The Davis treatment plant was originally constructed in 1954.



The project consisted of the roof demo, and replacement of 12 buildings throughout the entire facility. All carpentry work, lightning protection, and all MEP work associated with roof were also included in the project.


All roof areas included the removal of various low slope roof systems down to the existing structural decks. Decks, varied from metal, structural concrete, lightweight insulating concrete, and tectum. The new replacement roofs consisted of tapered rigid insulation over the flat existing deck structures, with multiple applications, ranging from mechanically attached, fully adhered, and the combination of both, mechanically fastening the bottom layer, and adhering, numerous top layers, with a fully adhered TPO single-ply membrane.


  • Asbestos removal was handled by the City of Austin, subcontractor, and all work was coordinated so the roof was watertight each day.
  • There was strict adherence to all rules for access to site buildings, including the badging of men, and all subcontractors under roofing scope.
  • The project met HUB participation from all subcontractors.
