Springs protection projects
Implementation projects to improve the health of Florida’s springs and their ecosystems are a major component of the St. Johns River Water Management District’s Springs Protection Initiative. These projects support solutions to the springs in a multitude of ways, and, for example, include reclaimed water projects that decrease nitrate pollution by reducing or eliminating direct wastewater discharges and using this water to replace other irrigation sources, so that nutrient uptake and improved reductions can occur in the irrigated turf or other plants. Also, the reclaimed projects protect spring flows by reducing demand for surface and groundwater withdrawals.
Projects, listed by the spring system within their influence, include:
Volusia Blue Spring
City of DeLand Reclaimed Water Retrofit, Part B and Wiley Nash Water Reclamation Facility Upgrades
This project includes additional filtration facilities to treat surface water to augment reclaimed water supplies. The project will result in 4 million gallons per day (mgd) treatment capacity. Funding for the $3.8 million project comes from the local government and the district.
City of DeLand Wastewater Treatment Plant (WWTP) Aeration and Instrumentation Upgrades to Enhance Nutrient Removal
This $1.32 million cooperative project will expand and upgrade the 6 mgd Wiley M. Nash Water Reclamation Facility in the city of DeLand. The project will upgrade the treatment system process to increase nitrogen reduction capabilities by 45 percent. The project will benefit Blue Spring with an expected reduction of approximately 35,000 pounds of total nitrogen annually. In addition to contributing to the draft total maximum daily load (TMDL) reductions required for Blue Spring, the project will enable implementation of the proposed aquifer recharge components of the adopted Blue Spring Minimum Flows and Levels (MFLs) Prevention and Recovery Strategy.
West Volusia Water Suppliers Reclaimed Water Interconnect Phase 2-A
This project includes the construction of interconnect transmission lines to the reuse distribution systems of the cities of DeLand and Deltona and Volusia County. Funding for the $6 million project comes from the local governments and a 2013 legislative appropriation for St. Johns River restoration and protection.
Orange City Reclaimed Water Main and Meters
This $490,000 project will help protect and improve spring flow at Volusia Blue Spring by reducing Orange City’s groundwater withdrawals by nearly 18 percent. This project is anticipated to help to achieve Volusia Blue Spring Minimum Flows and Levels Prevention/Recovery Strategies. The reclaimed waterline project will extend from Harley Strickland Boulevard northward along Veterans Memorial Parkway in Orange City. Additionally, 160 homes in the Oakhurst subdivision will receive new individual water meters for the reclaimed water and backflow prevention devices for the potable water system. This conversion to reclaimed water will reduce potable water demand in the neighborhood.
City of Deltona Golf Course Reclaimed Water Expansion
This $1.8 million cost-share project includes the construction of an interconnection of the city’s reclaimed water distribution system to the city’s golf course. Approximately 0.9 mgd will be made available from this project and includes a new reclaimed water pumping station and a 1.0 million gallon ground storage tank for the golf club. The new pump station and storage tank will enable the golf course to cease its use of groundwater for irrigation.
City of Deltona Howland Boulevard Phase 3 Reclaimed Water Expansion
This project will extend the reclaimed water main to provide reclaimed water to businesses and schools along a 4.5-mile portion of Howland Boulevard. Multiple shallow irrigation wells will be taken off-line as a result of this supply of reclaimed water.

Volusia County will expand the availability of reclaimed water to residents in the DeBary area. Funding for the $3.4 million project comes from the local governments and a 2013 legislative appropriation for St. Johns River restoration and protection.
City of Sanford Enhancements to Aquifer Storage Recovery (ASR) System
The use of ASR will contribute to an overall reduction in the rate of regional groundwater withdrawals during times of the year when spring flows are at their lowest, thereby reducing stress to Wekiwa‐Rock springs located to the west and Volusia Blue Spring located to the north. ASR will be used to supplement limited groundwater supplies for meeting peak potable demands. Up to 2.0 mgd of water would be injected into the ASR well in January, March, September and December, for a total groundwater offset of 240 million gallons per year, representing approximately 7 percent of the city’s annual consumptive use permit allocation. Total project cost is $1.66 million.
City of Sanford — International Airport Reclaimed Water Expansion Phase 1
This $683,048 project provides for a reclaimed water extension along Lake Mary Boulevard, westward from the Sanford Water Resource Center to the Brisson West Development and Silvestry Development, for irrigation to 1,025 homes. This benefits springs protection by reducing the amount of water withdrawn from the aquifer. The project will conserve 0.277 mgd of potable water, addressing the city’s projected 2030 water supply deficit in advance, and will reduce groundwater withdrawals impacting Lake Sylvan. Future phases of the project will address nutrient reduction to the Middle St. Johns River Basin.
Silver Springs and lower Santa Fe River
Gainesville Regional Utilities “Smart” Meter and Automatic Meter Infrastructure (AMI) Implementation (lower Santa Fe River)
This $212,000 project is a continuation of a water conservation program within GRU’s service territory. This program encompasses a meter change-out that will more accurately reflect customer consumption as well as provide on-demand meter reading, leak detection, theft detection and backflow detection. By using the “smart” meter and customer-side leak functionality, 50 percent of existing leaks should be captured and fixed, potentially reducing unaccounted for water use by 6 percent, or 120,000 gallons per day. The project will support the protection and restoration of the Lower Santa Fe and Ichetucknee rivers and their associated priority springs.
Gainesville Regional Utilities (GRU) Smart Meter Installation Program (lower Santa Fe River)
This cost-share agreement includes the installation of “smart” meters within GRU’s service territory, saving 0.10 mgd through the installation of up to 2,000 smart meters and the implementation of an Automatic Meter Infrastructure (AMI) Program.

The objective of this project is to issue rebates for the replacement of a maximum of 700 older water-wasting toilets with 1.28 gallons per flush toilets within the district’s boundaries. The project will save 6.5 million gallons per year. Total project cost is $100,000.
City of Ocala Water Reclamation Facility (WRF) 2 Nutrient Reduction Project (Silver Springs)
The city of Ocala, the district and Florida Department of Environmental Protection (DEP) are working in partnership on a $12 million water quality improvement project that will reduce up to 623,000 pounds of nitrogen pollution per year going into Silver Springs. The project involves upgrading the city’s Wastewater Facility #2, located near Silver Springs, to advanced treatment, significantly improving the quality of the effluent discharge of the facility.
Marion County Silver Springs Shores Reuse to Spruce Creek Golf and Country Club (Silver Springs)
This cooperative project will upgrade the existing wastewater treatment plant located in Silver Springs Shores to reclaimed water quality effluent standards. It will also relocate the wastewater discharge from the facility, which is located near Silver Springs, and redirect it for beneficial reuse at area golf courses, further away from the spring. The combined plant upgrade and relocation of the discharge will eliminate a nutrient source near the head of the spring, and result in an estimated reduction of more than 40,000 pounds of nitrogen entering the aquifer per year. The project will reduce water withdrawals for the area golf courses and improve the flow of Silver Springs. Funding for the $8.2 million project comes from local government funds, the district, DEP and a 2013 legislative appropriation for St. Johns River restoration and protection.
Lake County Soil and Water Conservation District Water Savings Partnership
This $396,900 project proposes to implement water-saving practices, including automatic shut-off valves, soil moisture indicators and rain sensors, more efficient irrigation equipment replacement or upgrades, and management tools recommended by its Mobile Irrigation Lab staff. The Mobile Irrigation Lab conducts nearly 125 irrigation evaluations per year, and this project will increase water efficiency by converting current, less-efficient systems to newer, more-efficient systems. Some participating growers and nurseries are located in the Wekiwa springshed.
City of Apopka Kelly Park Road Reclaimed Water Main Extension and Ponkan Road Reclaimed Water Main Extension
This $1.4 million water supply project will extend the city of Apopka’s reclaimed water distribution system to provide 5.5 mgd of reclaimed water to the future Kelly Park Crossings development in Apopka. The Kelly Park Road and Ponkan Road extensions provide necessary connections and further expands their regional system that provides reclaimed water sources for current and future development and will offset groundwater withdrawal needs in the springshed of the springs of the Wekiva River. This project, along with the Orange County Utilities’ Wekiwa Springshed alternative water supply expansion, and in combination with the city of Altamonte Springs’ project introduced the previous year and known as A-FIRST, provides multiple sources of alternative water supply to the city of Apopka.
