Specifications include, but are not limited to: 1. The following narrative is provided as a general description the project background and goals. Design or operating parameters and proposed improvements beyond those that relate to this project are provided as information based upon the current understanding of the project and shall not constitute the final basis of design and/or operation of the current or proposed facilities. 2. In Phase 1 the Provo WATRR Center will have a nominal average hydraulic capacity of 16 million gallons per day (mgd) with three (3) secondary process trains. The plant is designed to be expanded in the future to approximately 21 mgd nominal average biological loading capacity, and 24 mgd hydraulic design capacity with five (5) secondary process trains. The membrane filtration system procured under this contract will be designed for a nominal average hydraulic capacity of 16 mgd but the initial procurement will include only that membrane filtration equipment necessary to achieve a nominal average hydraulic capacity of 14 mgd. The additional 2 mgd of membrane filtration equipment will be procured at a future date under conditions described in the Proposal Form for Procurement Contract. 3. The secondary treatment process will consist of advanced biological nutrient removal to achieve phosphorus and nitrogen limits with chemical addition as needed. The bioreactors will consist of RAS fermentation, anaerobic zones, anoxic zones, and aerobic zones. 4. Mixed liquor from the bioreactors will be delivered to the membrane filtration system by gravity. Permeate pumps will feed the downstream existing UV system. 5. Return flow (RAS) from the membrane tanks to the bioreactor will be provided using return pumps. The pumps will be rated to provide one (1) to four (4) times the bioreactor influent flow, unless higher rates are needed by the membrane filtration system. 6. Metal salt (ferric chloride, ferric sulfate, or alum) solutions may be fed at multiple locations upstream of the membrane system to improve phosphorous reduction. The metal salt liquid chemical storage and feed equipment will be provided by others to meet the requirements of the proposed system. 7. The waste activated sludge wasted stream (WAS) will be pumped from the end of the bioreactors, upstream of the membrane tanks. The WAS stream will be drawn from the bioreactor overflow. 8. Project is planned to be executed using the Construction Manager/General Contractor (CM/GC) delivery method. In case this construction delivery method is used, MSS is required to coordinate with OWNER, ENGINEER and CONTRACTOR (CM/GC).
