60 Sixth Avenue Water Main Replacement

This is a water main replacement project with respective street and sidewalk replacement. Approximately 650 feet of 6 inch cast-iron pipe (vintage 1974) will be replaced with 8" PVC. Automate manual operating procedures, motorize concentrator adjustment and motorized valve adjustor for the small influent valve. This project will be informed by the Treatment Study Replace the roofs on the 5 collector wells, 3 deep wells, and emergency generator building. Modify the lagoon outlet structure to an open channel design. This project will be informed by the Treatment Study. Extend 20-inch water main from Madison to Clinton on Market St. Tie in 12-inch on Clinton St. to 16-inch at Bloomington St. This project will be preceded by the abandonment of the 20 inch main along the old Davenport St right-of-way between dormitories. Decommission the Bloomington ground storage reservoir within the University of Iowa Campus Parking Ramp and return the space to the University of Iowa per the associated 28E agreement. The 28E agreement expires on December 31, 2038. (Resolution No. 88-176) Remove the existing soda ash and ammonia chemical feed systems. Replace the existing powdered soda ash feed system with a liquid soda ash feed. The use of soda ash is to increase alkalinity of the source water for lime softening purposes. This is necessary if drawing from the river. This project will be informed by the Nutrient Study. Clean and inspect the laterals of the Sand Pit Pumping Station. Replace and repair the lateral isolation valves and t Construct a two million gallon ground or elevated storage reservoir within the East Pressure Zone. Replace the two million gallon ground storage reservoir located on Sycamore Street with a ground or elevated two million gallon storage tank along McCollister Blvd. Upgrade or expand the buildings at the Emerald and Rochester ground storage reservoirs. Add a third pump to both ground storage reservoirs. Replace the backup generators at both ground storage reservoirs. Install 16-inch water main parallel to the existing water main on Melrose Ave from Dublin Rd to Westgate St and on Westgate St from Melrose Ave to Benton St. This project would reduce velocity headloss from the Emerald ground storage reservoir to customers west of US-218, increasing service pressure. This project will be evaluated by hydraulic modeling after the West Side GSR project is completed. Construct a new bulk water filling station on the Public Works Campus to replace the station to be demolished at the existing Equipment / Transit site. Upgrade aging water treatment facility lighting to LED's
