1 GROUP PROJECTS!!!! Pre-class preparation questions: what is design? what bothers you most about having to work in groups to learn and accomplish projects? what have you found to be helpful about working in groups? how would you define team-based learning? what are characteristics of an engineering design team? what are roles and responsibilities of group members? what are possible solutions to typical problems encountered in group learning? Review group projects Assign groups Determine group project assignments (6 groups 3 projects) CEE 484

2 what is design? I. client II. end-requirement of effluent and residuals X work backwards considering all design variables to arrive at solution

3 I client II. end-requirement of effluent and residuals design variables? wastewater constituents policy and regulations septic tank design sanitation and public health concerns conveyance system treatment technologies drainfield technologies intended reuse of effluent nutrient removal wastewater effects ecological impacts of constituents site evaluation soils, groundwater, slope, available land, etc treatment capacity of soils climate operations and maintenance economic situation social preferences client demands what else???

4 Problem Scoping Problem definition – criteria and constraints Information gathering – facts and data to solve problem Developing Alternative Solutions Generation of ideas and concepts Modeling – estimating measurements Feasibility analysis – judgment of workability Evaluation of alternatives – e.g. matrix Project Realization Decisions - specifying elements Problem Solving Methodology

5 Project Realization Solution of the problem Communication of the results

6 II. what bothers you most about having to work in groups to learn and accomplish projects? III. what have you found to be helpful about working in groups? IV. how would you define team-based (vs. group) learning? Discussion questions… I. design variables and relevant concern for onsite or decentralized

7 Results of research on team projects show members: obtain higher levels of understanding develop ability to “use” course concepts (apply to problem solving and decision making) learn more about how to learn develop skills for working effectively on a team appreciate value of team approach for solving complex tasks Why are we working on team projects?

8 What are characteristics of an engineering design team? small group of people complimentary skill set committed to common purpose employing common approach…. ….that they are mutually accountable for!!!!

9 What are roles and responsibilities of group members? technical expertise personal preferences team coordinator individual roles sub-teams

10 Social Loafing Research says……. …….top two considerations for building successful teams are: Group does not: require individual accountability call for input from each group member reward members for group work provide regular feedback People are: naturally shy dominators of discussions not confident in their knowledge not committed to team success bashful about appearing disagreeable not convinced problem is complex enough to require entire group Team Cohesiveness

11 be respectful get to know each other organize tasks, goals, and roles delegate work divide leadership role amongst the group members collaboratively determine next steps be able to rely on team members to complete their task meet regularly to communicate information to team members Keys to success in team projects? Accountability – peer assessment

12 Introduction to group projects: 1. Merrill Hall, University of Washington Campus 2. Jiuzhaigou National Park, Sichuan Province China 3. Hood Canal, Puget Sound, Washington State x

13 Merrill Hall More Hall

14 Center for Urban Horticulture Union Bay Natural Area

15 May 21, 2001, an arsonist placed a gasoline bomb in Professor Toby Bradshaw’s office

16 Rebuilt with LEED certification Interconnectivity of water natural resources manufactured materials people, knowledge and action Low flush toilets, waterless urinals and grade of pipe to sewer result in solids settling and clogging pipe

17 The UW has hired you to evaluate and design an onsite wastewater treatment and reuse system for Merrill Hall that fits in with the existing structures and the original project goals. In addition to key aspects that you identify, the following must be considered in your report to the UW: 1.treatment system requirements 2.installation and space requirements 3.ability to handle diurnal flows and seasonal school schedule flows 4.operational and maintenance requirements 5.approximate cost of installation and operation 6.acceptability to faculty, staff and students 7.area needed for effluent storage, reuse 8.how system will be managed 9.potential for environmental education

18 x Jiuzhaigou National Park “The Valley of Nine Villages” The only park in China to have the combined certifications of UNESCO World Heritage Site, World Biosphere Reserve, and Green Globe 21

19 Tourists are only allowed access to the park on an extensive boardwalk network and via the parks bus transportation system

20 Current tourist system: high operating costs insufficient human and environmental health protection resource intensive requirements JNP has a goal in place to replace the sanitation and toilet system

21 The administration of JNP has hired you to evaluate and design a sanitation and toilet system for the tourists. In addition to key aspects that you identify, the following must be considered in your report to JNP: 1.protect the environment of JNP 2.footprint 3.more economical system 4.reliability 5.ease of maintenance 6.sanitation and hygiene 7.aesthetics 8.usability 9.environmental education 10.beneficial reuse 11.park capacity

22 map taken from Hood Canal 60-mile long fjord in the Puget Sound

23 Map taken from Hood Canal Dissolved Oxygen Program Experiencing seasonally decreasing levels of dissolved oxygen (DO) Nitrogen sources potentially contributing to the problem: septic systems fertilizers from residential use and commercial forestry pets alder trees

24 The Puget Sounds Action Team has hired you to develop two options for a cluster of 22 homes currently on septic systems to consider: 1.each individual homeowner upgrade to a recommended individual onsite treatment method 2.the entire development upgrades to a recommended alternative for a clustered treatment system

25 The following must be considered in your report to the PSAT on the two alternatives 1.the treatment system must reliably produce an effluent that is sufficiently low enough in nitrogen for protection of the Hood Canal 2.installation and space requirements 3.ability to handle diurnal and seasonal flows 4.operational maintenance requirements 5.relative cost difference between the on-site and decentralized system 6.acceptability to homeowners 7.area needed for effluent dispersal 8.ownership and management of the cluster system 9.potential for funding or subsidies to aid the homeowners in upgrading their system

26 Group assignments Hood Canal Merrill Hall Jiuzhaigou Merrill Hall Jiuzhaigou
