Agreement D12-030 <br />2. Initial Sampling and Water Quality Analyses in Low Flows <br />A minimum of one grab sample will be collected at each candidate diversion location <br />along with flow measurements. Laboratory testing will be conducted for selenium, total <br />dissolved solids, and nitrate in the water samples using protocols previously used for the <br />Nitrogen and Selenium Management Program. <br />Deliverables: <br />• Laboratory test results and flow measurements <br />Existing Utility Research <br />A preliminary utility search will be conducted at each candidate diversion location. It is <br />assumed all general utility information will be obtained from the City of Santa Ana. <br />Utilities of interest include: <br />• Sanitary sewer <br />• Local storm drain facilities <br />• Existing potable/reclaimed water pipelines <br />• Natural gas pipelines <br />• Petroleum pipelines <br />• Electrical service <br />Deliverables: <br />• Incorporate Existing Utility Research into Conceptual Site Layout <br />4. Develop Preliminary Diversion Sizing Requirements <br />Preliminary sizing of the candidate diversion locations will include the following: <br />• Establish flow rates and identify gross solids removal requirements <br />• Establish volumetric requirements for a wet-well storage basin <br />• Establish general flow and conveyance requirements <br />• Establish pumping requirements assuming an eight-hour runtime <br />A general listing of equipment requirements and associated sizing will be provided. <br />Deliverables <br />• Incorporate Preliminary Diversion Sizing Requirements into Conceptual Site <br />Layout and Conceptual Design Report <br />Conceptual Site Layout <br />Conceptual site layouts will be developed for each of the candidate diversion locations. <br />The conceptual site layouts will include the following: <br />• Identify site constraints for each candidate diversion location <br />• Site configurations for the proposed channel diversion structures
