The CM-At Risk project included an addition of a membrane water treatment facility and improvements to the existing treatment plant. The membrane facility consisted of an aesthetically pleasing sloped, standing-seam roof with architectural louvers supported by lightweight metal trusses atop 12-inch integrally colored burnished-face masonry blocks. HVAC units are concealed from view by matching masonry courtyard walls and are accessible through ornamental iron gates. The lower section of the building houses a chemical room, blower room, fire riser room, control room, restrooms, electrical room and board room. The chemical room contains transfer pumps, storage tanks, totes, secondary containment pits with a special concrete coating, sump pumps and piping.
