Camp Koholowo Water Treatment

1. Camp Koholowo Water Treatment KWHEngineering Preston Kutney Joey Willardson Erick Hollenbaugh • 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: • a reliable, economical water filtration system • monitoring configuration • housing appropriate for all seasons. • Perform cost and reliability analysis of two design alternatives: • Solar Power (at spring) • Generators (at camp) Cost: • Solution: • Place a new 5,000 gal tank at the camp with an accompanying shed that houses the water treatment and monitoring apparatus. • Install a water treatment system that includes a 3-micron pre-filter, 1-micron main filter, and a chlorine injection system. • The housing is to be built on a concrete slab that was designed for the full tank weight and snow load. The shed housing was designed for a snow load of 200 psf. • The water tank size was based on the daily camp water demands and the flow capacity of the filter. • The proposed location was chosen for proximity to the main water line and the camp. This does not include build cost Our principle concerns in selecting between these 2 designs were lifetime costsand reliability. MC Series Multi-Cartridge Filter Housings
