in the 2003 Sewer Master Plan. <br />3. Update the major wastewater dischargers, including the industrial dischargers, and <br />cross -check this list with the City's largest water users. Update all point sources and <br />their estimated average daily process flows. <br />4. Review the Infiltration/Inflow Study included within the 2003 Sewer Master Plan. <br />The update shall recommend the appropriate inflow and infiltration rates in the <br />analysis. <br />5. Based on the above information, recommend the design flow criteria for both dry <br />weather and wet weather flow parameters to be used in determining the existing flow <br />conditions. Be sure to evaluate any need to reduce the previous design flow criteria <br />due to water conservation measures since the 2003 Sewer Master Plan. <br />6. Review the hydraulic deficient areas of the City's sewer system contained in the 2003 <br />Sewer Master Plan. Consultant shall propose and execute a plan to measure and <br />collect sufficient dry and wet weather wastewater flows to utilize in calibrating the <br />sewer model. The plan shall include the proposed locations of the temporary flow <br />monitoring stations and the procedures for monitoring. <br />For the proposal, assume five (5) flow monitoring sites will be required. A minimum <br />of two (2) week dry weather flow monitoring will be required, During the rainy <br />season, the same sites shall be monitored for a minimum of two (2) weeks. The <br />consultant shall provide the required traffic control plans and traffic control during <br />the flow monitoring, including the set -up and removal of the equipment from the <br />manholes. <br />8. In addition, to confirm the anticipated flows, the consultant shall field inspect at peak <br />flow hours those manholes in known or suspected problem areas to confirm the depth <br />of flow (or surcharge) within the manhole. For this proposal, include field inspection <br />often (10) manholes will be required. The inspection of each manhole shall be <br />performed during peak dry weather flow and during peak wet weather flow (during a <br />rain storm). The consultant shall provide the required traffic control during the field <br />inspection. <br />D. Sewer System Capacity Analysis <br />1. Recommend the capacity analysis criteria to be used in the update. <br />2. Include within the analysis, the impacts of any backwater from OCSD's trunk sewers. <br />This information shall be obtained from OCSD and their most recent modeling of the <br />trunks. <br />3. The capacity analysis shall be performed for the current conditions and for conditions <br />25K -15 <br />
