Process Description
The Towanda Municipal Authority water system draws from two sources. The Eilenberger Spring is 17 miles from Towanda and has a gravity flow rate of 400 to 450GPM. At this site chlorine, sodium hydroxide and corrosion inhibitor are paced with flow. Chloride residual is monitored and recorded. The James Street Wells are located in town and pumps for the two wells are alternated monthly with a flow rate of 300 GPM. The system includes an Equalization Tank, which replaced an open reservoir. The selected Well pump is cycled to maintain tank level during peak use periods while system input from the Spring is constant. Monitoring and control are accomplished with a Personal Computer (PC) HMI at the Authority office.
