Clean waterPrimary effluent Testing for Coliform Methods: Laboratory One time use field tests Presence tests Local means Pros: Reveals Fecal coliforms Other bacteria Portable Easy to Use Cons: Cost - $10/each Non-reusable Restricted to occasional use

Enjoy Clean Water! Clean bio-layer Switch filters Set flow rates Pump water Ownership Responsibility Better Health Added Convenience User Experience User Attributes User Actions

Business Model The CYEC kids will own the system and they make it a success by applying the system to other applications Goal: Provide reliable and cheap means of Coliform testing to the eco-village and the near-by communities. Will be saving $500 per year in Municipal Water costs! Start up cost: $1,684.70
