Waco Dissolved Air Flotation Facilities

PROJECT COST: $44,285,914

The Waco Dissolved Air Flotation Facilities project encompasses the design, planning and execution of construction administration services performed for a new 90 million gallon-per-day water treatment plant. The new plant will reduce the algae populations in Lake Waco that cause undesirable taste and odor. It will also provide additional water supply for the region.

The dissolved air flotation water treatment plant features rapid mix, two-stage flocculation and dissolved air flotation. The dissolved air flotation process will remove the algae from the water along with other suspended particles, minimizing the further release of taste and odor compounds into the water. Immediately adjacent to the dissolved air flotation facility is a 90 mgd ozone facility for disinfecting the clarified water and for removal of the taste and odor compounds that were already imparted to the water prior to removal from the lake.
