Page 2 of 9 Task 105 — Project Administration Engineer will perform general administrative duties associated with the project, including preparation of correspondence, project administration, monthly invoicing, and progress monitoring. Task Series 200 — Flow Monitoring Plan, Data Analysis, Sewer Line Conceptual Design Task 201 — Development of a Flow Monitoring Plan In consultation with the City, Engineer will conduct a review of existing and past flow monitoring and infiltration & inflow (I&I) reduction efforts by the City. Changes made to the system and I&I reduction work completed after the 2000 Wastewater Facilities Plan will be documented. The City, in consultation with the Engineer, will select a Flow Monitoring Consultant or alternate approach to flow monitoring. The Engineer will work with the Flow Monitoring Consultant and the City to develop a flow monitoring plan which will define the extent, schedule, and procedures for the collection of flow and rainfall data. The flow monitoring plan will include an installation and removal (if applicable) plan for temporary and permanent flow meters, rainfall gauges, and groundwater gages. The plan will include a schedule for meter installation, periodic calibrations, and data collection. Monitoring will be conducted continuously so as to include low -flow season (winter) and maximum flow season (late summer) conditions and startup and shutdown of the irrigation system. This scope of Basic Services includes consideration of up to 8 open -channel flow meters, 5 rain gages, and 5 groundwater gages for a monitoring duration of 12 weeks Flow meters will be sited at key locations in the system. Rainfall monitoring locations will be selected to adequately collect and describe the spatial distribution of rainfall and considering ease of service and gauge security. Field verification of metering sites will be performed with the Flow Monitoring Consultant to ensure that the sites are accessible and suitable for accurate monitoring. Any cleaning that is required will be performed by the City. The instruments used to monitor open channel flows will be depth and velocity type flow meters or approved equal. The Flow Monitoring Consultant will check each instrument routinely to determine if re -calibration is needed. For the open channel meters, a minimum of four calibration checks will be undertaken during the course of the monitoring period. The Flow Monitoring Consultant will also check pump station, rainfall gauges, and groundwater gauges for proper operation. The following information will be provided to the City by the Flow Monitoring Consultant upon completion of the flow monitoring effort: • Map showing flow, rainfall and groundwater metering locations. Page 3 of 9 • Table of metering location showing pipe size, location of sensor, meter type, meter installation date, meter removal date, total days of usable data collected. • Table of rainfall gauge locations with installation date, meter removal date, type of meter. • Site visit worksheets for each meter. • A bubble diagram depicting the flow relationship of each meter to other meters and major facilities such as pump stations and treatment plants. • Monthly hydrographs of flow data showing flow depth, velocity, flow rate, and rainfall. • Database of flow data in Excel or Access format in 15 minute sample intervals. The data will show flow depth, velocity, and flow rate in mgd. • Meter calibration data — manual depth and velocity readings at each site four different times during the metering period. • Database of rainfall data in inches at 15 minute intervals. • Database of groundwater level data. Task 202 — Data Analysis Upon completion of the flow monitoring effort, the Engineer will analyze the data. Analysis will include the following. • Average daily dry weather flow (7 day low flow during monitoring period) • Infiltration flow during dry weather/high groundwater conditions. • Inflow rates. • Total peak flow for selected design condition. • Average daily flow estimate. • Analysis of WWTP flows relative to collection system flows. • Comparison of irrigation season to non -irrigation season flows. • Comparison of results to previous flow monitoring efforts. The Engineer will summarize the flow analysis and results in a technical memorandum (TM) and will submit the TM to the City for review. The collected and analyzed data will be used for calibration of the wastewater collection system model. Task 203 —Sewer Line Conceptual Design Completion of the conceptual -level design of the sewer line associated with the SR24 casing pipe will be completed under this task. Task Series 300 — Model Preparation and Software Selection Currently the City has two steady-state hydraulic models — a collection system spreadsheet model that was built by HDR as part of the 2000 Wastewater System Master Plan, and a partial system model constructed in HYDRA. Page 4 of 9 For system simulation and to evaluate storage and hydraulic gradients, "unsteady -state" flow models are recommended. Unsteady -state software computes the time -varying flows at each point in the system over the duration of the model simulation (typically ranging from one hour to several days). This computation therefore accounts for the attenuation of peak flows in the drainage system. The computations also account for storage capacity in the pipes and other conveyances and structures, and flow volumes lost to spills or overflows from the system. For the purpose of optimizing the capital improvements plan (CIP), it is recommended that the City utilize an unsteady -state computer model. Several unsteady state computer models are available and widely used for wastewater system modeling (namely XP- SWMM from XP -Software, MOUSE from the DHI, and InfoWorks from Wallingford Software); all are similar in that they allow for import and export of inventory data and modeling results, and link with GIS software. The following tasks reflect the steps necessary to prepare and select the model. Task 301— Review Back • round Data and Pre. are Data Re • uest The following are the primary types of data that will be required to construct the wastewater system model: • Hydrologic (e.g. precipitation, topography, soil characteristics, land use) • Hydraulic (e.g. pipe and manhole characteristics, other facility characteristics - pump stations, force mains, storage areas) • Calibration and verification data (precipitation and flow monitoring data) Possible sources for the information above include the following: • System models and documentation from previous planning efforts • City's geographic information system (GIS) system • City's AIMMS system • Any needed as builts or other system drawings • Natural Resources Conservation Service (soil survey) • Past and future flow monitoring results • Additional survey data • City maintenance personnel The Engineer will work with the City to complete a data assessment for the data sources listed above and other relevant sources that may be provided by the City. The data assessment will outline the data source for each element of the wastewater collection system inventory that is required for modeling. Any data discrepancies (gaps) will be noted, along with a proposed solution for correcting each discrepancy. Correcting discrepancies is not included in Basic Services. Page5of9 Task 302 — Evaluation of Software Models The Engineer will work with the City to evaluate and select a software model. Knowledge acquired during Task 101 (Initial Meeting) and Task 301 (Data Assessment) will aid in the evaluation. Other differentiating factors including cost, feature set, and user interface will be discussed. Conclusions reached in the evaluation will be summarized in a brief TM. City will decide which software model will be used and purchased. Cost assumes the software (MOUSE assumed) will be purchased by the City and Engineer will use the license Task Series 400 — Model Construction and Calibration Task 401 — Land Use and Service Area Evaluation In consultation with the City, and in review of the 2004 Wastewater Facility Plan, the Engineer will define the current and build -out service area for the study. Boundaries of the study area will be incorporated into the City's GIS system by the City. In addition, the Engineer will gather population, land use, and large user information from the City (or regional planning agency) for the study area for each design year. Population and land use will be expressed in terms of equivalent population which includes people, industrial, institutional, and commercial units. Current and projected future wastewater flow from satellite facilities (e.g. the City of Union Gap and the Terrace Heights Sewer District) will be estimated. A summary of the overall study area population and population equivalents will be prepared in a TM and submitted to the City for review and comment. After approval by the City of the study area existing and future population projections, the population will be spatially allocated throughout the study area. The spatial allocation will be based on census tract or traffic analysis zone, or other geographic spatial information provided by the City. Considerations for the population allocation will be areas already developed, developable areas, densities for new development, and growth patterns and "hot -spots" as identified by the City. The spatial allocation will be made for each project design years. A summary of the population and population equivalent data for each design year will be prepared in a TM and an exhibit depicting both existing and design year population densities will be prepared and submitted the City for review and comment. The spatially allocated population and population equivalent data will be used for system analysis after approval by the City. Task 402 — Collection System Inventory The Engineer will work with the City to identify trunk sewers, pump stations, and force mains to be modeled on a sewer GIS file provided by the City. The modeled system will include 12 -inch and larger sewers plus any 8 -inch and 10 -inch sewers that are critical to the modeling effort. After the selected pipes and facilities have been approved by the City, the Engineer will prepare an inventory database for all sewer lines, pumping Page 6 of 9 stations, and force mains to be modeled using attribute data provided by the City. Only the attributes necessary for hydraulic modeling will be inventoried under this scope of work (e.g. length, diameter, slope, invert and ground elevation data, pump capacity). Questionable data will be discussed with the City for correction, confirmation, or assumption criteria. This task will also include 20 person days of additional review of record drawings and up to 10 days for selective field verification of data. The Engineer will prepare a digitized map from existing digitized and paper sewer maps to be used or project exhibits. Streets and major surface features will be provided by the City in electronic format and will be referenced to the digitized sewer base map. The digitized sewer data will include node locations and trunk sewer lines; drainage basins and subsystems; and identification numbers. The map will show the sewers in sufficient detail for planning purposes only. Location with respect to streets, rights-of-way, and other structures will be approximate. The Engineer will prepare a plot of the modeled system and a hardcopy printout for the City to review in TM format. A final version of the TM will include the City's comments. Task 403 — Establishing Existing and Future Flow Estimates in Desktop Analysis The Engineer will utilize the results from the flow data analysis completed as a part of Task 202 and the future land use and population density projects from Task 401 to estimate future flows. The Engineer will define flow parameters to generate design flow curves for use in estimating flows from existing and future service areas. Task 404 — Hydraulic Modeling of Existing System The Engineer will establish flow allocation criteria for assigning existing and future flows to the hydraulic model, and allocate flows to the hydraulic model by individual manholes (point loading) or distribution across a subsystem as appropriate. The Engineer will define sewer design criteria for minimum slopes, minimum velocity, defmition of sewer overloading (allowable D/d), and the percent of overload allowed before relief will be considered. These criteria will be evaluated with the City before the completion of any hydraulic capacity analyses. The model will be calibrated against the flow data collected in Task Series 200. Model parameters will be modified until computer -calculated peak flows and travel times are in acceptable agreement with monitored or projected design flows based on monitored data. The Engineer will complete a low flow plus infiltration flow analysis. A system analysis for existing low flow conditions will be performed using the calibrated computer model. Normal low flow and peak infiltration flow components will be analyzed in conjunction with available pipe capacity to determine if any low flow hydraulic problems currently exist. The Engineer will complete a peak flow analysis. A system analysis for current population and selected peak flow conditions will be performed using the calibrated Page 7 of 9 computer model. The projected peak flow (given system restrictions) will be determined for each line. Relief requirements will not be determined at this time. The Engineer will prepare a TM of calibration and output results and a plot of existing hydraulic conditions for the City to review and comment. This TM will include a review of pipe and pump station capacity through the system. Task Series 500 — Preparation of a Wastewater Collection System Master Plan Task 501— Identify and Screen Collection System Alternatives The Engineer will run the model for the ultimate build -out condition (last design year), and evaluate configurations for collection system improvement alternatives to serve future growth for the design years. Alternatives will consider capacity and storage impacts, as well as impacts of I&I reduction. The WWTP facility plan will be considered while developing the alternatives. The Engineer will work with the City to establish an appropriate level of protection. The alternatives will identify major interceptors, pump stations, and storage facilities to serve the service area. A workshop will be conducted with the City to discuss alternatives and the drawbacks and benefits of each alternative. Task 502 — Hydraulic Analysis of Alternatives and. Development of Recommended Plan The Engineer will define new interceptors, extensions, and other facilities, to serve growth and to convey wastewater to the WWTP. Analysis will be conducted for the entire design period. The Engineer will run intermediate design years and evaluate phasing of pumping station improvements, abandonment of existing pumping stations, and phasing of new sewer lines. The improvements will be itemized into specific capital improvement projects for the design period. In addition, a rating matrix will be developed that will summarize key issues, such as growth potential and cost/benefit factors, to help prioritize the capital improvement project list for phased implementation. Planning level costs will be summarized for the selected improvements. The Engineer will develop a TM that presents the analysis of alternatives and development of the capital improvements plan (CIP) for review and comment by the City. In addition to the CIP, other recommendations important for system planning will be identified for future consideration. Task 503 — Wastewater Collection System Master Plan Report The Engineer will prepare an executive summary of the project and assemble all TMs into one report binder for review and comment by the City. The draft report will include the findings and recommendations for the collection system, a narrative discussion of results of the investigation, including exhibits (e.g. map of existing system with recommended projects), tables, graphs, and the computer analyses of the collection system. Ten copies will be submitted for review. Page 8 of 9 Following receipt of review comments, the Engineer will prepare and submit the final report. A total of ten reports will be provided. Electronic files of the final model will be provided to the City. All figures will be in PDF format. Task 504 — Hydraulic Model Delivery Workshop The Engineer will conduct a 4 hour hydraulic model delivery workshop for the City. Additional follow-up service is not provided as a part of Basic Services, but can be provided on an hourly basis.
