Abstract

Rural Alaskan drinking water distribution systems are faced with unique obstacles that make chemical disinfection challenging. Due to the extreme low temperatures present in the majority of these communities, water distribution systems are engineered to constantly circulate to prevent freezing. The constant circulation of water makes chlorine residuals difficult to manage from water treatment plant dosage to distribution system residual maintenance. Therefore, I propose creating a scaled model of the typical Rural Alaskan recirculating distribution system. During study I will monitor the chlorine residual and dosage to maintain a prescribed concentration to meet regulatory requirements throughout the entire model. Additionally the scaled model developed for this project presents an opportunity to work with Brigham Moore, a
Master in Science in Civil Engineering Candidate at UAA, working on computer modeling of these systems. This collaboration will be a valuable experience for myself as a perspective graduate student. The primary goal of this research is to develop an understanding of chlorine dosing and decay throughout drinking water recirculation systems. This will require a sufficient understanding of chlorine decay rates and water age in the system.
