Sanitary sewer and water main installation has been completed on Prairie Street. After the water main is in place, it must be disinfected with chlorine, and pressure tested to ensure there are no leaks. The chlorine is then flushed out, and a water sample is taken and tested to see that it is free from bacteria. Only after the new main is successfully tested can service laterals be re-connected. This is why the street must be dug up several times during the process. Sanitary sewer is installed first, because it is the deepest. Then water main is installed. Finally, service laterals are installed after the entire segment of water main has been installed and passed testing.
During the week of May 5th, new water and sewer service laterals will be installed on Prairie Street. Water service to individual houses will be interrupted for approximately 1 – 2 hours while the reconnections are made.
Concrete removal on Blackhawk Avenue from Main to Prairie will also begin Monday, followed by water main installation. Sidewalk will remain in place for now. The asphalt has also been milled off between Prairie and Beaumont, but no further work will occur until later in May.
The asphalt milling on Beaumont from Frederick to McLeod will be completed but no utility work is likely to begin until the following week.
The high river level is still preventing any more sewer work on Main Street. Blackhawk Avenue will be closed between Main and Prairie, but the Main/Blackhawk intersection is open, allowing access to the island.
