Safco Inc., of Hayden, has won a $2.2 million project to install sewer lines in the Rotchford Acres area near 16th Avenue and Sullivan Road, say county officials.

Cindy Grasso, a county program specialist, says the planned sewer-line project is part of a larger effort to eliminate septic tanks over the Spokane-Rathdrum Aquifer. The county is paying for the project with help from the Washington state Department of Ecology, Grasso says.

Most of the work will be done in an area bordered by 16th on the south, 11th Avenue on the north, Shamrock Street on the east, and Sullivan on the west.

Kevin Cooke, county sewer planning and design manager, says the project will provide sewer service to approximately 150 homes.

The project will include laying about 13,090 linear feet of eight-inch diameter sewer pipe, and 300 feet of two-inch diameter pipe, making 143 sewer connections, and installing 50 sewer manholes. The work also includes replacement of asphalt pavement disrupted by the project, and construction of 13,600 feet of curbing.

Among the streets where the work will be done will be: 11th Avenue, 14th Avenue, 16th Avenue, Homestead Court, Pioneer Court, Galway Court, Timberline Drive, Rotchford Drive, Limerick Drive, and Shamrock Street. The project area also will include Cheryl Court, he says.

Grasso says the work is to be completed sometime this construction season. She wasn't sure when it would begin.
