Volusia County Septic System Reduction Plan 1.0 Introduction According to the Florida Department of Environmental Protection, septic systems, when properly designed, constructed and maintained, perform well in sparsely populated rural areas where large tracts of lands are available for wastewater disposal. However, in urban and coastal areas, septic systems can have a significant impact on resources, particularly in residential communities interspersed with tidal canals.
It is estimated there are approximately 90,000 individual on-site septic systems in Volusia County. Septic systems do not adequately remove nutrients such as nitrogen and phosphorus, which result in aquatic growth such as algal blooms in our waterways, which shade out marine vegetation and deplete fish life. Septic system effluent migrates from our yards into our waterways. It also seeps into the groundwater which can ultimately migrate to the Floridan Aquifer, resulting in high nutrients levels in our springs and drinking water supply.
Reducing the number of septic systems by connecting to a central sewer system will allow for advanced wastewater treatment at a County or municipal wastewater plant. Some county/municipal wastewater plants treat wastewater to public access reclaimed water standards, which allows for beneficial use of the wastewater effluent and reduces demands for potable water.
Volusia County has established a long term goal of eliminating all septic systems in areas where they are an inappropriate method of effluent disposal. Due to the costs of retrofitting these areas with central wastewater collection systems, the County must prioritize the elimination of septic systems. This plan focuses on elimination of septic systems near key water bodies such as the Mosquito Lagoon and Halifax River, located along the east coast of the county, the St. Johns River located along the west boundary of the county, and within the basins of significant springs such as Blue Spring and Gemini Spring located in southwest Volusia County.

2.0 Collection System Alternatives There are three different alternatives for providing central sewer collection as follows:
Alternative 1 - Low pressure, small diameter sewer system with individually owned effluent pumps or grinder pumps
Alternative 2 - Conventional gravity sewer system Alternative 3 - Vacuum sewer system
2.1 Alternative 1 - Low Pressure Small Diameter Sewer System A low pressure small diameter sewer system consists of a small diameter (minimum 2 inches) force main that is typically installed within the road right-of-way (ROW). The system requires installing a septic tank effluent pump or a grinder pump at each residence to convey wastewater to the low pressure sewer system. Advantages
pipe sizes from 2 inches to 6 inches
layout independent of topography
reduced excavation compared to gravity
sewer system infiltration greatly reduced
eliminates manholes
requires less power than vacuum system
lower construction costs than other alternatives Disadvantages
effluent pump or grinder pump needed at each residence
electrical power required
air release valves needed
flushing connections required
periodic pumping of septic tank for effluent pump system
power outage disturbs service 2.2 Alternative 2 - Conventional Gravity System This alternative allows for gravity flow of wastewater to a central gravity sewer line located in the road right of way. The gravity collection systems flow to county or municipal wastewater pump station that pump wastewater to the wastewater treatment plant. Nearly all communities with central sewer service have gravity collection systems. Gravity systems have the highest construction cost but the lowest operational cost. Advantages
effluent or grinder pump not required at each residence
lower operational cost compared to low pressure system or vacuum system
most reliable collection system alternative Disadvantages
higher initial construction costs
3
2.3 Alternative 3 - Vacuum Sewer System A vacuum sewer system utilizes a partial vacuum to transport sewage through the collection system. Vacuum sewer systems include a central vacuum station, which maintains the system at a sub-atmospheric pressure, with small diameter vacuum pipelines located in the road ROW. Service connections are made to each residence and a holding tank replaces the septic tank. A vacuum valve located in the holding tank allows rushing air from the service connection to transport the sewage to the central vacuum station. The central vacuum station operates 24-hours a day. Advantages
effluent or grinder pump not required at each residence
reduced excavation compared to gravity sewer system
grade and depth not critical Disadvantages
electrical power required at central vacuum station
vacuum valves have a shorter life than pumps
higher energy consumption than other alternatives
major odor problem at central vacuum station
vacuum loss will render the system non-operational, requiring immediate repair 2.4 Selected Alternative Low pressure / effluent pump systems may be appropriate for rural or low density developments. For most urban, medium to high density applications, gravity collection systems are preferred by most communities. The planning level costs provided in this plan are based on the use of Alternative 2 conventional gravity sewer collection.

3.0 Planning Level Costs For the purpose of this planning document, the design, permitting and construction costs for gravity sewer retrofit projects have been estimated based on the density of developments as follows:
High density: $15,000 per lot Medium density: $20,000 per lot Low density: $25,000 per lot
The primary elements of a gravity sewer retrofit project are:
Installation of gravity sewer piping and manholes
Acquisition of land for utility owned pump stations
Installation of utility owned pump stations and force mains
Dewatering as needed and proper disposal of water
Installation/replacement of water distribution system as required
Rebuild and pave roadways
Maintenance of traffic
Survey, engineering design and permitting Additional costs for connection to central sewer include the following on a per lot basis:
Impact fee for sewer: $2,900
Septic tank/drain field abandonment: $1,000
Connection of home sewer plumbing to central sewer: $1,100 Estimated Total = $5,000 Many residential developments with individual on-site septic systems also have individual on-site wells for water service. Additional costs for connection to the central water system include the following on a per lot basis:
Impact fee for potable water: $1,500
Connection of home plumbing to central water: $ 500 Estimated Total = $2,000

3.1 Design, Permitting and Construction Time Frames The time frame required to complete design, permitting and construction of a gravity sewer retrofit project via the design-bid-build procurement process is approximately 3 to 4 years depending on the size of the project. The primary components of the design-bid-build procurement process are as follows:
Advertisement of a Request for Statement of Qualifications (RSQ) for engineering design and permitting services, bidding assistance and construction phase services
Establishment of a selection committee for review of RSQ’s
Short listing and selection of an engineering consulting firm by the selection committee
County Council approval of an engineering consulting firm
Issuance of a Notice To Proceed to the Council approved engineering consulting firm
Completion of survey, geotechnical services, engineering design and permitting, preparation of construction bid documents by the engineering consulting firm
Advertisement of bid documents
Construction bid opening
Review of bids by the engineering consulting firm
County Council award of a construction contract to the responsive and responsible low bidder
Notice to Proceed issued to the low bidder
Construction
Construction closeout The time needed for project initiation through issuance of the Notice To Proceed with construction should be approximately 24 to 26 months, regardless of project size. The time needed to complete construction may vary from 16 months to 24 months depending on the project size. A typical project timeline for a gravity sewer retrofit construction project is depicted Figure 3.1-1 below. This timeline assumes that all necessary rights of way / easements exist, that land acquisition is not required.

4.0 Priority Areas for Central Sewer Retrofit This plan prioritizes the following four (4) water bodies for elimination of septic systems:
Mosquito Lagoon Watershed
Halifax River Watershed
Blue Spring Basin
Gemini Springs Basin 4.1 The Mosquito Lagoon Watershed, located in Southeast Volusia County, north of and connected to the Indian River Lagoon, is an Outstanding Florida Water. Much of the existing development along the US Highway 1 corridor south of Edgewater receives sewer service via individual on-site septic systems. In recent years, Mosquito Lagoon and the Indian River Lagoon have experienced algal blooms that have resulted in a decline of aquatic grass beds, fish kills and higher than normal dolphin and Manatee deaths. Abnormally high nutrient loads to the lagoon, from both direct and indirect discharges, are believed to be contributing to the algal blooms. Effluent from septic systems located in the Mosquito Lagoon watershed is a significant contributor to the nutrient overloading. Figure 4.1-1 depicts the developments in Southeast Volusia, within the Mosquito Lagoon Watershed, that are priority areas for elimination of septic systems, and how the developments could potentially be broken out into sub-areas for incremental completion as cost share grant funding becomes available. The sub-areas have been established based on each development’s location relative to the lagoon and/or tidal canals that discharge to the lagoon. The highest priority has been given to those developments located east of US Highway 1, adjacent to the lagoon, with tidal canals connected to the lagoon. Wastewater flows from these areas would be pumped to Volusia County’s Southeast Regional Water Reclamation Facility for treatment. The following is a description of each of the priority areas identified in Figure 4.1-1: Area 1 Indian Harbor Estates This area contains approximately 304 lots. It is bounded by Indian Creek Road, US Highway 1, Ariel Road and the Mosquito Lagoon. The development is characterized as high density. The majority of lots in the development are located on canals that lead to Mosquito Lagoon. The area receives potable water service from Volusia County. Due to its high density and location relative to canals leading directly to the lagoon, it is ranked as top priority for retrofit with a central sewer collection system. The planning level costs to retrofit the area with central sewer are as follows: Construction: $4.15 million Engineering: $0.41 million Subtotal, public improvements: $4.56 million ($15,000/parcel) Sewer impact fee and on-site improvements: $1.52 million ($5,000/parcel) Total: $6.08 million ($20,000/parcel)

4.2 The Halifax River Watershed covers the remaining coast line of Volusia County north of the Mosquito Lagoon Watershed, from the New Smyrna Beach area north to the county line. The Halifax River Watershed is one of the most urbanized watersheds in Volusia County. Although most of the area is served by central sewer, there are pockets of older development in the watershed that are served by individual septic systems. One of the most significant of these areas is the north peninsula, north of the city limits of Ormond Beach where there are approximately 5,000 high density residences located on the relatively narrow peninsula between the Halifax River and the Atlantic Ocean. Due to poor tidal flushing, water quality is poor in this portion of the Halifax River. Figure 4.2-1 depicts developments in the unincorporated area of the North Peninsula that have been identified for elimination of septic systems, and how these developments could potentially be broken into projects for incremental completion as cost share grant funding becomes available. The following is a description of each of the priority areas identified in Figure 4.2-1 along with planning level costs to retrofit each area with central sewer: Area 1 River Breeze Estates This area contains approximately 1,010 lots. It is bounded by Plaza Drive, Longwood Drive, John Anderson Drive and A1A. The development is characterized as high density. Potable water service is provided by City of Ormond Beach. The planning level costs to retrofit the area with central sewer and water are as follows: Construction: $13.77 million Engineering: $1.38 million Subtotal, public improvements: $15.15 million ($15,000/parcel) Sewer impact fee and on-site improvements: $5.05 million ($5,000/parcel) Total: $20.20 million ($20,000/parcel) Area 2 Sunny Shores This area contains approximately 780 lots. It is bounded by Hibiscus Drive, Seaside Drive, John Anderson Drive and A1A. The development is characterized as high density. Potable water service is provided by City of Ormond Beach. The planning level costs to retrofit the area with central sewer and water are as follows: Construction: $10.64 million Engineering: $1.06 million Subtotal, public improvements: $11.70 million ($15,000/parcel) Sewer impact fee and on-site improvements: $3.90 million ($5,000/parcel) Total: $15.60 million ($20,000/parcel)

4.3 The Blue Spring Basin is the groundwater/drainage basin that contributes to water flow in Blue Spring, a first magnitude spring located along the St. Johns River, west of Orange City. The Blue Spring Basin, as established by the St. Johns River Water Management District, is identified on Figure 4.3-1. A Total Maximum Daily Load (TMDL) has been established by the Florida Dept. of Environmental Protection (FDEP) for excess nutrients in Blue Spring and the Blue Spring run. A significant contributor of nutrients to Blue Spring is septic systems located within the spring basin. Figure 4.3-2 depicts the developments in Southwest Volusia, within Volusia County’s utility service area, that have been identified for elimination of septic systems. Due to the high costs associated with central sewer retrofit, the developments have been broken out into projects to take advantage of state and/or of federal funding as it becomes available. The project areas are numbered based on their proximity to Blue Spring. There are several developments on the map with relatively large (one acre or greater) lots that are not a high priority for central sewer retrofit in this plan. The following is a description of each of the priority areas identified in Figure 4.3-2 along with planning level costs to retrofit each area with central sewer: Area 1 Orange City Terrace This area contains approximately 610 lots. It is bounded by Fern Street, Shirley Street, Live Oak Avenue, and the FEC Railroad to the west. The development is characterized as medium density. Water service is provided by individual, on-site wells. The development is located within the Blue Spring Basin. The planning level costs to retrofit the area with central sewer and water are as follows: Construction: $11.09 million Engineering: $1.11 million Subtotal, public improvements: $12.20 million ($20,000/parcel) Sewer impact fee and on-site improvements: $3.05 million ($5,000/parcel) Water impact fee and on-site improvements: $1.22 million ($2,000/parcel) Total: $16.47 million ($27,000/parcel)

4.4 The Gemini Springs Basin is the groundwater/drainage basin that contributes to water flow in Gemini Springs, a second magnitude spring located south of Dirksen Drive, east of 17/92 and west of I-4 in the City of DeBary. Gemini Springs discharges to the DeBary Bayou, which empties into Lake Monroe, a water body along the along the St. Johns River. A significant contributor of nutrients to Gemini Springs is septic systems located within the spring basin. Figure 4.4-1 depicts the developments in the Gemini Springs Basin, within Volusia County’s utility service area, that have been identified for elimination of septic systems. Due to the high costs associated with central sewer retrofit, the developments have been broken out into projects to take advantage of state and/or of federal funding as it becomes available. The project areas are numbered based on their proximity to Gemini Springs. There are several developments on the map with relatively large (one acre or greater) lots that are not a high priority for central sewer retrofit in this plan. The following is a description of each of the priority areas identified in Figure 4.4-1 along with planning level costs to retrofit each area with central sewer and water (where currently not available): Area 1 Plantation Estates This area contains approximately 480 lots.
