off meeting identified in Subsection 1.1.2 the Engineer anticipates that liquid and solids treatment strategies will be discussed and finalized to the extent that preliminary process modeling can be completed. 1.3.2 Evaluate four potential WWTP sites. For each potential site, the Engineer will take into consideration how each site can be connected to the existing or future wastewater conveyance system. The Engineer will consider distance from the conveyance system to the potential site, plant discharge locations and topographic features that may create hydraulic challenges. 1.3.3 Evaluate up to three different technologies for solids treatment based on input received from the City during the kickoff meeting. The Engineer will include in each technology evaluation an assessment of land requirements, e.g., acre/dry ton solids throughput, capital cost/dry ton throughput, odor potential, power, and annual operating and maintenance ("O&M") costs. During the kick-off meeting, the Engineer will facilitate a discussion regarding the potential for the City to lead an effort to construct and operate a regional biosolids facility because of the potential economic advantages associated with constructing and operating a larger regional facility. However, for the purpose of this proposal, efforts associated with assisting the City in pursuing a regional facility have not been included. Should the City wish to include this activity, it can be scoped and provided later as an additional service. 1.3.4 Evaluate no more than three different liquid treatment strategies. Results of the liquid process modeling will be used to establish preliminary process layout configurations, footprint requirements and associated planning level capital cost requirements. In addition, as part of the liquid process modeling, the Engineer will consider impacts of the different solids treatment options on liquid treatment. In order to limit liquid treatment scenarios for consideration, the Engineer will first complete the solids treatment analyses to an extent that will narrow solids treatment options to one preferred alternative, which the Engineer will then use in all liquid process modeling evaluations. 1.3.5 Provide the City with electronic copies of the following deliverables: a) Technical memorandum documenting the solids treatment evaluations and the recommended option. This evaluation will consider up to three technologies and will present information described in Subsection 1.3.3. b) Technical memorandum documenting liquid treatment evaluations. The Engineer will provide modeling results, ability to meet anticipated permit requirements, resultant footprint requirements and preliminary capital cost information. 1.4 TASK 4 - ALTERNATIVE DISCHARGE EVALUATION The Engineer will: 1.4.1 Evaluate up to four potential receiving streams within the anticipated vicinity of the WWTP. The Engineer will conduct this evaluation in a two-step process. Initially, the Engineer W W WTP Site Location Assessment - CH2M Hill 4
