West Side Loop Water Main Replacement

West Side Loop Water Main Replacement ESI was selected by the Cobb County-Marietta Water Authority to design and manage construction of 29,000 feet of 48-inch water main for the West Side Loop. The project consists of construction of a water transmission main in Cobb County along Friendship Church Road, Dallas Highway, cross country along an existing power line easement owned by Georgia Transmission Corporation, Burnt Hickory Road, Paul Samuel Road and Stilesboro Road. Design and bid of the project has been completed and construction is expected to be completed by the first quarter of 2017.


Athens Highway to Loganville Highway Water Main Replacement

Athens Highway to Loganville Highway Water Main Replacement ESI was hired by the Gwinnett County Department of Water Resources to provide engineering design services for the replacement of 13,200 linear feet of existing 48-inch pre-stressed concrete cylinder pipe (PCCP) water transmission main along Langley Road, Hope Hollow Lane, and Hope Hollow Road/Moon Road between Athens Highway (Highway 78) and Loganville Highway (Highway 20) with 48-inch diameter ductile iron pipe (DIP). This project also includes installing 6,450 linear feet of 8-inch DIP to remove services from the 48-inch transmission main for two subdivisions and 14 single family residences. The new 48-inch water main will connect to the existing 48-inch DIP water main on the north side of Athens Highway and the existing 48-inch DIP water main of the south side of Loganville Highway.

Upper Flint River Water Supply – Contract 2Upper Flint River Water Supply – Contract 2

This City of Griffin project involved the construction of 21 miles of transmission main from a new water treatment plant in Pike County to the City of Griffin (8.8 miles of 36-inch ductile iron pipe; 1.2 miles of 30-inch ductile iron pipe; and 11.0 miles of 24-inch ductile iron pipe). The segments near the water treatment plant were designed for working pressures above 200 psi and tested at 315 psi. The end of the project consisted of 24-inch DIP installed in congested streets in Griffin with narrow rights-of-way and multiple existing utilities. Portions of the main were installed with extra protection against corrosion.


East Canton Water Main

East Canton Water MainThis project involved the installation of 6,500 LF of 20-inch ductile iron pipe water main and appurtenances along SR 20 in Cherokee County prior to a GDOT road widening project. The project also involved re-connection of an existing 8-inch CIP water main at eight locations.

ESI provided preliminary engineering, design, bidding and construction management services to the City of Canton.

The main purpose of the water main installed in this project was to provide water to Coweta County.


Mulberry Rock Road Water Main and Union Pump Station

Mulberry Rock Road Water Main and Union Pump StationIn an effort to provide a more reliable water distribution system with higher operating pressures, the Paulding County Water System proactively identifies system upgrades to improve customer service. In its planning process, Paulding County identified a project to improve service to the western areas of the County. The project was to replace an older booster pump station with a new booster pump station and a new transmission main.

The Paulding County Water System hired ESI to perform the preliminary engineering, final design and construction management of this project. The project included a new 3,000 gpm booster pump station readily upgradeable to 4,000 gpm and 4,500 LF of 16-inch diameter ductile iron water main. ESI performed the preliminary engineering, preparation of plans and specifications, permitting, and construction administration.
