BACKGROUND:
In February 2022, Water Utilities issued Bid 22-021, Park Addition Water Main Replacement. The project includes Center Street, Ellsworth Street, Brainard Street and Loomis Street from 5th Avenue to Ogden Avenue. The project also includes the replacement of the storm sewer on Ellsworth Street from 5th Avenue to 7th Avenue.
The purpose of the project is to replace aging and functionally deficient water mains in the Park Addition subdivision. Water mains vary in size from four inches to 10-inches. The bulk of the existing water main is cast iron installed in the 1930s, with segments of poor-quality ductile iron pipe installed in the 1960s and 1970s. Four and six-inch pipes will be upsized to eight-inch pipes and 10-inch pipes will be upsized to 12-inch pipes in accordance with City standards.
The storm sewer on Ellsworth Street is being upsized to a 30-inch pipe to improve stormwater conveyance and drainage characteristics of the area.
