PROJECT DESCRIPTION:
The Joint Water & Sewer Commission (JWSC) requested engineering services to complete a study to determine the cost to extend service to multiple areas that were without public water and/or sewer. GWES completed the study to extend sewer service to three (3) areas in Glynn County that were located near the existing sewer system. In order to determine the potential costs of providing utility service to each of these areas, GWES compared the capital costs and operation and maintenance costs associated with the installation of three (3) types of sewer systems: gravity, low-pressure grinder, and low-pressure STEP system. The areas included the area west of Highway 341 and north of Highway 33, the area east of Highway 341 and north of Community Road and west of Old Jesup Road, and parts of the Arco Community. The areas consisted of approximately 840 parcels with up to 960 potential connections. This cost study was based upon an in-depth review of existing conditions in each of the unserved areas obtained from existing GIS information, previous evaluations, field investigation, and coordination efforts with the JWSC. GWES put together schematic layouts of each system type in each of the three (3) areas. Based on those schematic layouts, GWES estimated the capital costs and operation and maintenance costs over 20 years associated with each system.
