Work of the Project generally includes expansion of the Hutto South WWTP. More specifically, the Work includes, but is not limited to, construction of the following 1. Facility 5, Site Civil Improvements: a. Site improvements including yard piping, grading, drainage, paving and stormwater management. 2. Facility 10, Headworks Improvements: a. Cast-in-place headworks structure with coarse (6mm) screening, bypass, and grit removal. b. Electrical room for headworks equipment. c. Screening and grit collection and storage. 3. Facility 15, Odor Control Improvements: a. Installation of a bio scrubber, ventilation fans and exhaust system for the influent lift station, headworks, and primary clarifier facilities. 4. Facility 16, 17 and 18, Primary Clarifier Improvements: a. Installation of a primary clarifier splitter box and two (2) primary clarifiers with spiral rake sludge collection system, scum pumping and primary solids pumping station. 5. Facility 19, 20 and 30, Process Train Improvements: a. Installation of two (2) common wall biological process basins with anaerobic, anoxic, and aerobic (A2O) treatment zones. 1) Basins will have mixers, baffling, aeration diffuser grids and internal mixed liquor recycle system with axial flow pumps. b. Process Trains will have an integral mixed liquor splitter box to distribute flow to the downstream clarification process. c. Installation of an independent process basin splitter box structure. The scope of this work package consists of the turnkey contruction and start-up of the tertiary filters (area 50), flow meter vault (area 54), uv, post aeration, and effluent metering (area 55), and non-potable water storage (area 70), less architectural, and as further described within the package inclusions and exclusions.
