2 Agenda Final Design System Integration Issues Requirements Update Testing Update Risks Project Plan Action Items Purchasing & Cost Summary Documentation Problem Management Review

3 Final Design

4 System Integration Two problems occurred during building: 1.Bolts were too short- easily fixed by getting longer bolts. Issue occurred due to a measurement assumption. 2. Placed mesh on wrong side of lid assembly Was not possible to fix but was able to use it for taste testing So far no problems have occurred that will prevent the collection of data.

5 Engineering Requirements and Test Plans Test Plans: HereHere

6 Turbidity & Flow Rate Testing Update Testing performed on water from pond near Global Village Genesee River was frozen over Three prototypes have been used to test how well the assembly works Testing has been successful! We plan to continue flow and turbidity tests through the first week in April. – Genesee River water – Custom water (varying levels of sand and soil added to tap water)

12 Risks IDRisk ItemEffectCauseLikelihoodSeverityImportanceAction to Minimize RiskStatus 1Cleaning is difficult Users may not clean properly or often enough Difficult to take apart, reassemble339 Supply cleaning instruction, minimize number of parts, minimize disassembly/assembly time, visual cues to indicate which side of filter is upClosed 2 Costs more that $25/unit Product may not be used Materials selection, construction339Design to be low costClosed 3Stress concentration Damage to filter within 2 year lifespan Repeated use of filter236Spread load out around edge of filterOpen Stress on clamp/fastener326Calculate necessary force ratingOpen 4 Flow rate does not meet requirement Not meeting customer needs Insufficient area of filter/diffuser, filter isn't porous enough236 Increase surface area of filter, find more porous materialsOpen 5 User not detecting tear in filter Particles escape into clean water undetected Filter is hidden from view224 No hidden filter, instruct user to inspect both sides of "sandwich"Open 6Corrosion Water tastes bad, equipment fails Improper cleaning, interaction of materials with water133 Use materials which won't corrode, provided clear cleaning instructionOpen 7Weight is too much Too heavy for women and childrenMaterials selection133 Ergonomic study, design to allow women and children to useClosed 8Incorrect usage Filter could break, water not cleaned Not intuitive, poor instructions133 Use visuals whenever possible, minimize text, poka-yokeOpen 9 Stability issues with bucket bucket tips, breaks, etc poor structural design, unlevel surface212 Design proper attachments, make sure surface is level prior to useOpen 10Leakage UV Absorbing particles reach "cleaned" waterNot a tight seal111 Use rubber gasket, clamped down tightlyClosed 11Filter may be too tall Not enough room for "clean" water Planning issues, imprecise calculations111 Calculate necessary height ASAP, test for fill amountOpen
