2. Problem: The camp’s water source, a groundwater spring, must have 4-log virus removal The camp’s water source, a groundwater spring, must have 4-log virus removal The spring is ¼ mile from the camp The spring is ¼ mile from the camp The only electrical power comes from generators located at the camp The only electrical power comes from generators located at the camp Leasing land from US Forest Service makes construction at spring complex Leasing land from US Forest Service makes construction at spring complex

3. Approach: Design Objectives: Design Objectives: 1.A reliable, economical water filtration system 2.Monitoring configuration 3.Housing appropriate for all seasons Perform cost and reliability analysis of two design alternatives: Perform cost and reliability analysis of two design alternatives: 1.Solar Power (at spring) 2.Generators (at camp)
