Past Projects


The major projects undertaken by the Cobb County Water System typically involve upgrades or expansions to our four water reclamation facilities, but also include large-diameter tunnel projects to provide wastewater conveyance and flow equalization storage capacity. Other typical construction projects include water main repairs/replacements, sewer line extensions, and sewer line rehabilitation.
