only source discharging a greater volume (0.14 mgal/d) than its designed flow 

 (0.10 gal/d) is the system operated by the City of Carrabelle. It discharges 

 into St. George Sound. 



Gulf County 



In 1979, Werwahatchka was the only domestic sewage system listed in Gulf 

 County. It has a design flow of 0.20 mgal/d. This system discharges into the 

 Chipola River. There is no information about a domestic wastewater system for 

 Port St. Joe. 



Okaloosa County 



The Okaloosa County water and sewerage system has the largest design flow 

 of the 21 domestic wastewater sources in the county. It is designed to handle 

 3.0 mgal/d, but its average daily flow is only 2.22 mgal/d. The following 

 three treatment plants have an average daily flow that is greater than design 

 flow: Fort Walton Beach's two sewage treatment plants (2.31 mgal/d as opposed 

 to a design flow of 1.70 mgal/d, and 0.25 mgal/d compared to 0.12 mgal/d), 

 and the City of Niceville's system (0.53 mgal/d compared to 0.12 mgal/d). 

 Most of the discharge is into Santa Rosa Sound. 



Walton County 



All eight of the domestic sewage systems in Walton County are relatively 

 small. The largest system in the county (operated by the municipality of 

 DeFuniak Springs) has a design flow of only 0.48 mgal/d. All the systems are 

 operating below their design flow. 



PROJECTED TREATMENT CAPACITY NEEDS 



In the near future, Pensacola, Fort Walton Beach, and Panama City are 

 likely to need greater domestic sewage treatment facilities. 



In Escamb-ia County, the growth in design capacity for domestic sewage 

 treatment systems is expected to be 9.41 mgal/d in the year 2000 (Table 28). 

 By projecting the historical mean, about 20 new treatment facilities are 

 needed. In Okaloosa County, growth in design capacity is projected to in- 

 crease by 5.55 mgal/d and 11 new treatment facilities will be needed. The 

 growth in design capacity for Bay County is projected to be 3.99 mgal/d, and 

 up to 28 new facilities will be needed. The number of new facilities is 

 relatively large because, historically. Bay County has operated a considerable 

 number of small systems and unless there is an abrupt change in local poli- 

 cies, this trend is expected to continue. 



The other four counties (Franklin, Gulf, Santa Rosa, and Walton) are 

 projected to have relatively little increase in design capacity and few new 

 facilities. Of the four counties, Santa Rosa County will likely have the 

 greatest increased need, and Gulf County the least (Florida Department of 

 Environmental Regulation 1981).
