Three water main replacement projects are scheduled for construction in the summer of 2021. The projects listed below are scheduled to go out to bid in early February and will be awarded at the end of March.
All of the 2021 projects involve replacing cast iron pipe that has advanced levels of electrolysis-caused corrosion.
Two of the three projects are located within the Columbine Hills Subdivision, which contains some of the oldest water mains in the District. The pipe scheduled for replacement was installed in 1960 and was not protected from corrosive soils, which is the current practice. The third project is located in the Leawood Subdivision, where a substantial amount of older cast iron pipe is also located. Combined, eight breaks have occurred on these three water mains, including four that occurred in 2019.
