Coweta County and the city of Senoia will start negotiations Monday afternoon on a deal the could ultimately provide the proposed McIntosh Village with one million gallons of sewer capacity.

Earlier this summer, Senoia learned it had obtained up to two million gallons a day in sewerage capacity from the EPD and the city is in the process of evaluating what to do with the capacity.

City administrator Richard Ferry said the city will probably only need an extra million gallons a day to sustain its projected growth for the next 20 years. If the city chooses to, it can reject the other one million gallons granted by the EPD and either expand its current land application system on Andrews Parkway or build a one million gallon treatment plant The city is currently using about 490,000 gallons a day.

Another option takes place Monday when the city negotiates with Coweta County over one million gallons of capacity to provide sewerage for the proposed McIntosh Village development near Sharpsburg.

In initial talks with the county, county officials have indicated a desire to either be part-owners of a new facility or to have some of the capacity reserved to sell to future county customers.

Another option is the city could try and provide the excess capacity to Reese Developers and McIntosh Village without dealing with the county. However, since McIntosh Village is in the unincorporated county, the city could face potential legal issues.

One of the biggest factors in the decision is cost and estimates for a new two million gallon per day facility range up to $20 million. Reese has pledged $8 million, but the city would have to look at several options to make sure the costs weren’t totally borne by current sewer customers.

Monday’s meeting starts at 3 p.m. Monday at City hall in Senoia.
