Task 1.1 Regulations Research: All applicable regulations for industrial discharge on the federal, state, and city level must be researched and understood. This includes the current permits held by Joy Cone as well as new standards that may pertain to a new water treatment system.
Task 1.2 Treatment Process Research: Research will be conducted to determine common treatment methods for TKN, BOD, and TSS in industrial wastewater streams common to the food processing industry. In order to fully evaluate all treatment alternatives, physical, chemical, and biological treatment methods will be investigated.
Task 1.3 Laboratory Preparation: To gain access to the laboratory at NAU, a lab binder must be prepared outlining the lab procedures and safety techniques that will be used. A sampling plan will also be created, which will allow the team to efficiently and accurately collect samples of the wastewater during the site investigation.
Task 2.1 Facility Investigation: A field visit will be conducted to examine the treatment equipment on-site. A complete process block diagram will be created to document the information collected during the facility investigation.
Task 2.2 Surveying: Land surrounding the Joy Cone factory will be surveyed with specific focus on the retention basin on site used for stormwater runoff. The purpose of this survey is to determine the elevations and land area that will aid in creating a design that may include the retention basin and ditch. Information gathered during the site visit will also be used for later hydraulic and hydrologic analysis.
Task 2.3 Sampling: Samples of the wastewater produced by Joy Cone will be collected in accordance with the sampling plan prepared in task 1.3.
Task 4.1 Creation of Topographic Map: Using survey data collected in Task 2.2, Honeycomb Engineering will create a surface using Autodesk Civil3D in order to analyze the topographic data of the site.
Task 4.2 Watershed Delineation: The watershed upon which the site is located will be delineated using United States Geological Survey (USGS) StreamStats program so that the watershed area may be determined.
Task 4.3 Collection of Rainfall Data: Rainfall depth and intensity data will be collected for the watershed using the NOAA Atlas 14 database.
Task 4.4 Determination of Time of Concentration: Time of concentration for the watershed will be determined using the rainfall data and the time of concentration equation.
Task 4.5 Determination of Peak Flow and Retention Volume: The ADOT Rational Method tool will be used to determine the peak discharge of the watershed. The peak flow rates will be applied to determine the volume of stormwater runoff required to be retained by the current basin. This will aid in determining the total required volume of the basin if used in the final design.
Task 5.1 Creation of Decision Matrix: All criteria for the final design will be investigated and summarized. This includes a synthesis of information provided by the client, relevant regulation and legislation, and information collected in Tasks 1-5.
Task 5.2 Creation of Design Alternatives: The team will investigate the possible biological, physical, and chemical treatment design methods. Several preliminary designs using these technologies will be created to meet the requests of the client and the criteria discussed in Task 5.1. This task will only create preliminary designs sufficient to be evaluated in the following task. A detailed design will not be completed during this step of the design process.
Task 5.3 Evaluation of Alternatives: After the list of potential treatment design alternatives is created, the decision matrix will be used to evaluate each against the criteria established in Task 6.1, and the preferred alternative will be selected.
Task 6.1 Completed Final Design: The selected preliminary design will be completed in this task. This includes sizing calculations, detailed drawings and analysis, construction plans, maintenance plans, and any other relevant documentation.
Task 6.2 Cost Analysis: A cost analysis will be performed for the final design to determine the construction, operation, and maintenance costs of the treatment method chosen.
Task 6.3 Evaluation of Impacts: The environmental, societal, and economic impacts will be considered and evaluated.
Task 7.1 30% Submittal: The 30% milestone will include Task 1.0: Preliminary Project Setup, Task 2.0: Site investigation, and Task 3.0: Analytical Testing. This deliverable consists of a 30% report and presentation and will be completed by February 10th, 2023.
Task 7.2 60% Submittal: The 60% submittal will include the tasks related to the design process. This deliverable consists of a 60% report and presentation and will be completed by March 10th, 2023.
Task 7.3 90% Submittal: The 90% progress submittal will include a final draft presentation and project website and will be completed by April 14th, 2023.
Task 7.4 Final Submittal: The final submittal will include the completed design report, website, and presentation of the project. The final submittal will be completed by May 5, 2023.
Task 8.1 Schedule and Resource Management: The schedule and team working hours will be tracked on a regular basis to assure the project stays on schedule and within budget.
Task 8.2 Meetings: A binder will be kept containing the agendas and meeting minutes of team, technical advisor, grading instructor and client meetings.
Honeycomb Engineering, Inc. will not be performing any analysis on the potable water in the Joy Cone facility, changing the location of any sanitary sewers, or testing/designing treatment for any pollutants that do not fall under Joy Cone Co.'s industrial pretreatment permit with the City of Flagstaff.
