The city of Waukegan in Illinois is currently undergoing a Capital Improvement Program, which will see approximately $US3 million spent on upgrades to its sewer and water systems. The city maintains over 400 km of sewer lines, and 320 km of storm water lines, and will use CCTV to assess the condition of this infrastructure and determine the necessary repairs. The project will be partially funded by federal grants and bond proceeds.

Meanwhile, in Sheboygan, Wisconsin, a major sewer pipe will be relined using cured-in-place-pipe (CIPP). After inspection using CCTV detected significant deterioration, $US2.7 million has been allocated to repair the thirty year-old sewer, which transports fifty per cent of the waste processed by Sheboygan Wastewater Treatment Plant.

The local council has contracted Pewaukee-based Trenchless Solutions Visu-Sewer to reline approximately 5 km of the 18 to 42 inch concrete sewer pipe. The company will reline the pipe using a fibreglass fabric coated with resin, which will be cured with hot water.

While the work is conducted, which is expected to last until October, sewage is being diverted into a bypass pipe. The project is being funded by a loan from the Wisconsin Department of Natural Resources.

Finally, Mt Pleasant in Michigan will spend approximately $US2.3 million over the next three years on relining its sewers. In 2010, the city will repair approximately 100 metres of 8, 10 and 12 inch sewer pipes, some of which are over fifty years old, to protect the health and property of local citizens.

By 2013, several kilometres of sewer pipe will have been repaired or constructed, and it is estimated that a further $US1 million will need to be spent after this date on additional required upgrades.
