Document Description
DSRSD proposes to install approximately 1,110 linear feet of 8-inch-diameter high-density polyethylene (HDPE) pipeline to connect an existing 10-inch-diameter pipeline within an unpaved extension of Cydonia Court with an existing 8-inch-diameter pipeline within Delamar Drive in the Tassajara Hills Development in the City of Dublin. Approximately 800 feet of the proposed pipeline would be installed using horizontal directional drilling, whereby a tunnel is drilled under the ground surface and the pipeline is then pulled through the underground tunnel. The remaining 300 linear feet of pipeline would be installed using standard open trench construction within existing graded areas associated with adjacent residential development. The proposed pipeline would provide a redundant potable water supply to the Tassajara Hills Development.
