Each year the District plans construction projects to repair or replace problem water and sewer main lines. The District has identified these projects for 2010.

Each year the District uses its video inspection van to inspect and analyze the sewer main lines of the District. Through this process, the District has identified 3,200 lineal ft. of 8-inch sewer main throughout the district for rehabilitation by installation of a special liner.  This work repairs damaged sections of the sewer mains without having to excavate the street to replace them.  The liners are made of a fiber material reinforced with resins to form a hard plastic shell inside the sewer line.  This method or repair saves the District approximately one-half of the normal expense of totally replacing the sewer main.

This same process helps us to identify different sections of the sewer main where a small spot repair of the main line can be done without having to dig up or excavate that location.

The District has the equipment to place a repair or patch made of fiber material reinforced with resin to form a hard plastic-type repair inside the existing line. By repairing these small sections of line, the District can maintain the integrity of the sewer system and save on the cost of doing excavations. This work usually involves several trucks and a large trailer working in the street for one day at each location. The District’s crews will be making repairs at over 50 locations this year. Tree roots, grease and debris are removed from the main lines that carry sewage to the treatment plant. The District has equipment to make repairs up to 10 feet in length. Major damage or longer repairs require slip lining, the process mentioned above or total replacement of the sewer mains. Right now, the District is able to do this maintenance work for approximately one-third of the cost of contracting this work out which saves Green Mountain customers quite a bit of money.

The District will be constructing new water lines to “loop” dead-end water lines in the Glennon Heights area. This will involve construction work in the following streets; W. Exposition Ave, W. Center Ave., W Glennon Dr., and W. Virginia Ave. between S. Miller St. and S. Kipling St. This work will help to provide better water quality and improve the control of system pressures in the area.

The District is in the process of replacing older pressure reducing valves used to control the water pressure on the District’s main lines. This involves the construction of a new vault to accommodate the new pressure reducing valves and controls. The District’s contractor will be working to replace pressure-reducing valves at W. Virginia Ave and S. quail St. and at Green Mountain Dr. and S. Yank St.
