Problem:• The camp’s water source,

a groundwater spring, must have 4-log virus removal

• The spring is ¼ mile from the camp

• The only electrical power comes from generators located at the camp

• Leasing land from US Forest Service makes construction at spring complex

Approach:• 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:

1. Solar Power (at spring)2. Generators (at camp)
