Applicant Information: University of Florida, Gainesville, Florida Principle Investigator: Eban Bean, Assistant Professor and Extension Specialist, Department of Agricultural and Biological Engineering, University of Florida Institute for Food and Agricultural Sciences, 2295 Mowry Rd., PO Box , Gainesville, FL , , Section 2: Project Specifics A. Project Goals and Objectives The goal of this project is to facilitate restoration of ecological integrity in the Indian River Lagoon (IRL) through restoring water quality by reducing stormwater runoff discharges and pollutant loadings from residential developments. Several septic decommissioning projects are on-going or scheduled throughout the IRL to reduce nutrient loadings over the next five years. When homes are hooked up to sewer systems, septic tanks are typically abandoned in place by puncturing the bottom and filling with sand or stone. These tanks are often 1,000+ gallons (equivalent to 20+ rain barrels) and, as an alternative, can be repurposed for rainwater harvesting to capture and eliminate stormwater runoff from roofs, provide an alternate water supply for irrigation, and/or facilitate groundwater recharge (F.A.C 64E-6.011(4)). This project seeks to promote conversion of septic tanks to cisterns by monitoring multiple conversion sites, using these data to develop an assessment tool, and creating a public outreach extension program focused on the effects of septic tanks and stormwater runoff on water quality in the IRL. Our objectives, outputs, and outcomes for this proposal are listed below.

3 Objectives 1) Coordinate with local government partners to identify and convert at least eight septic tanks planned for decommissioning to cisterns for capturing roof runoff that recover storage volume via infiltration or irrigation. 2) Evaluate water quantity and quality benefits of cistern conversions by regular monitoring and sampling at sites. 3) Develop and deliver an extension outreach program to educate citizens within the IRLNEP about septic systems, water reuse, and stormwater runoff. 4) Develop a publicly available tool for citizens and local governments to estimate runoff volume reductions, nutrient load reductions, and associated costs of converting septic tanks to cisterns. Outputs Photo documentation and total costs of converting septic tanks to cisterns from at least eight sites. Reductions in runoff volumes (eight sites: 183,000 gallons), pollutant loadings (eight sites: 3.1 lbs N/yr; 0.46 lbs P/yr), and potable water usage (four sites: 91,500 gallons), and increase in groundwater recharge (four sites: 91,500 gallons) based on monitoring data at eight sites. Fact sheets explaining benefits of septic decommissioning, reducing stormwater runoff, and reuse. A guide for homeowners with detailed instructions for converting septic tanks to cisterns. At least two peer-reviewed publications, including a UF/IFAS Electronic Database Information Sources (EDIS) publication. A Microsoft Excel tool that will calculate estimated: a) nutrient load reductions; b) runoff volume reductions; c) groundwater recharge; d) water conservation; and e) costs associated with septic conversion projects. Outcomes Short-term Outcomes: 1) At least eight homes identified for septic-to-sewer conversion will retrofit their decommissioned septic tank to a cistern for a) stormwater capture for infiltration, or b) rainwater harvesting for irrigation. Expected completion September ) At least 250 residents, county and municipality employees will increase their knowledge about a) how OSDS may be a pollutant source and/or b) beneficial reuse options, by 75% as determined by post-survey evaluations. Of those, twenty-five homes that have been previously identified for septic-to-sewer conversion will receive one-on-one site visits. Presentations and site visits will begin in 2017 and will be ongoing. 3) Determine the nitrogen and phosphorus load reductions and water conservation savings associated with beneficial conversions of decommissioned OSDS. Expected completion late 2018/early ) A Microsoft Excel tool will be developed to evaluate the expected volume reductions, loading reductions, water conservation, recharge, and costs based on site characteristics such as contributing roof area, tank volume, irrigable area, irrigation frequency, soil types, and depth to water table. Expected completion March Mid-term Outcome: 1) 1-5% of all homes identified for septic-to-sewer conversion within the SOIRLPP will retrofit their decommissioned OSDS for a) stormwater capture for infiltration, or b) rainwater harvesting for irrigation as determined by DOH abandonment permits. Expected completion December Long-term Outcomes: 1) Restore water quality and ecological integrity to the IRL by reducing stormwater runoff. Broadly promote and demonstrate benefits of stormwater harvesting and reuse as alternative water supply

4 2) Increase resilience to sea level rise and salt-water intrusion by increasing freshwater recharge and reducing potable consumption for irrigation. B. Technical Merit/Justification Elevated concentrations of nutrients have been problematic in the ground and surface waters along the Indian River Lagoon and have resulted in environmental health issues including algal blooms, eutrophic conditions, and the largest fish kill in recorded history. The majority of the Indian River Lagoon as well as the St. Lucie Estuary are under Basin Management Action Plans for impairment due to excess nutrients. Stormwater runoff is a major source of nutrients to the IRL and St. Lucie Estuary and Onsite Septic Disposal Systems (OSDS) have been shown to contribute N and P to groundwater and surface waters along the Indian River Lagoon. Thousands of homes will have their septic systems decommissioned and connected to sewers in the IRLNEP at an estimated cost of $43 million over the next five years. Another $11 million will be spent to reduce stormwater pollutant loadings. Within the area BMAPs, counties and municipalities are seeking additional technologies that can help them achieve the required TP and TN total maximum daily loads (personal communication). The proposed project will enhance current and planned septic decommissioning programs specifically in Brevard Co. (Breeze Swept, Rockledge; Merritt Island; Phase B, Palm Bay) and Martin Co. (North River Shores, Stuart; homes entering Grinder program). Converting septic tanks at the time of sewer connection is optimal to limit landscape disturbance, limit costs, and avoid tank abandonment and filling with stone or sand. In addition, offering home owners an opportunity to reduce their water usage and associated water and wastewater costs could incentivize them to proceed with sewer hookup. This project would also provide additional nutrient load reduction of 3.0 lb N/yr and 0.46 lb P/yr, and runoff volume reductions of 183,000 gallons/yr, which will be validated via monitoring. This project will be completed by March However, these program tools and materials, once developed can be used and adopted ad infinitum. C. Benefit(s) to the IRL Each site is unique (roof area, tank volume, and lawn area). However, a 1000 gallon tank can capture 1.25 in. of runoff from a 2,000 ft 2 roof area. Assuming 55 inches of rainfall per year and a capture efficiency of 50% results in a volume of 22,000 gal/year for each installation. Assuming runoff has concentrations of 2.0 mg N/L and 0.30 mg P/L, the runoff load reduction from this project is estimated to be 3.0 lb. N/yr and 0.46 lb. P/yr for eight homes. These estimates will be validated by monitoring at the eight conversion sites. Water levels will be continuously monitored within each cistern to quantify volume reductions. At least six samples will be collected from each cistern and analyzed for nutrient concentrations. At least one site will be paired with a control site (remaining on septic) and each will be instrumented to monitor runoff and groundwater (water level logger in multiple wells) flow rates. At least six runoff and groundwater samples will also be collected for nutrient analysis. Water quality analyses will include NH 4-N, NO 2+3-N, TKN, and TP. Brevard Co. will be conducting similar monitoring within the Breeze Swept neighborhood in Rockledge. Public knowledge increase will be quantified by post-survey evaluations. Other resource benefits of this project will include increased groundwater recharge, water conservation, and flood protection. D. Local commitment This project is not part of the Save Our Indian River Lagoon Project Plan (SOIRLPP), but it has been developed with input from Brevard County Department of Natural Resources (Virginia Barker, personal communication) and Martin County Utilities Department (Liz Wood, personal communication) so that it can be conducted in concert with the septic to sewer conversion projects, including those identified in the 2017 Supplement to the SOIRLPP.

5 E. Project Readiness Each conversion site will require a septic permit for decommissioning the septic system (F.A.C. 64E ). These will be filed once sites are identified and homeowners commit to participation. The design for the study is complete but the locations have yet to be determined. Well permits will be required for installation and will be filed once monitoring locations are identified. The project is ready to for awarding, as Brevard Co. is currently connecting homes to sewer within the Breeze Swept neighborhood of Rockledge.

Project Monitoring/Evaluation and Maintenance Plans Runoff Reduction: Runoff reductions will determined by monitoring water levels in each cistern. Water levels and tank geometries will be used to calculate a volume time series, which will then be analyzed with rainfall data and contributing roof area to calculate overall runoff reduction. In addition, we will monitor runoff from a converted lot and a control lot, prior to and after conversion. If multiple lots are adjacent to each other, every effort will be made to increase the number of converted lots draining to a runoff monitoring location, to more holistically evaluate runoff changes. Water Quality: Runoff will be sampled from converted and control monitoring locations. Three groundwater monitoring wells will be installed at a converted location and a control lot. Samples will be collected from wells on four occasions prior to conversion and six occasions after conversion. Water levels will also be continuously monitored in groundwater monitoring wells to estimate flow direction and rates based on soils information. Samples from cisterns will be collected on six occasions after conversion. Runoff, groundwater, and cistern samples will be analyzed for TKN, NH 4+ -N, NO 3- -N and TP. Flowrates and volumes will be used with water quality results to estimate nutrient loadings. Public Education: Attendees at public education events will complete post-surveys to evaluate knowledge gained. This project will be sustained by UF/IFAS extension offices in the IRL area continuing to deliver educational materials. The assessment tool will be made publicly available via the internet and through personal communications with county and municipal officials.

6 G. Citizen/Volunteer Engagement and Outreach Components Outreach programs will initially target homes in neighborhoods undergoing septic-sewer connection in Brevard and Martin Co., but will then expand to all five counties within the IRL. Outreach efforts will include one-on-one site visits to these communities as well community educational efforts through the St. Lucie County Florida Yards & Neighborhoods Homeowner Program. These programs are expected to reach 250 residents as measured by site visit and workshop evaluations. Upon completion of the Microsoft Excel tool, demonstrations will be made to county and municipal officials. H.

The Northern Indian River Lagoon (Project #s ROCK-26) and St. Lucie River (Project #s MC-16, PSL-9, S-14) BMAPs receive a TMDL credit for septic planned and/or ongoing phase out projects. This project will be a collaboration with these and other planned septic phase out projects. Once quantified, counties and municipalities may be able to receive extra credits through management actions associated with any additional nutrient reductions associated with conversion projects. This project promotes climate change adaptation by increasing stormwater capture capacity and conservation by providing alternate water supply for irrigation. Promoting infiltration of fresh water would protect against salt-water intrusion resulting from sea level rise. Palm Bay is one of the targeted conversion areas for this project and is classified as economically distressed due to low income and high unemployment. Section 3: Project Funding A.

8 Statement of Work Septic to Cistern Conversion: Repurposing septic tanks to reduce potable water use, runoff volumes and nutrient loadings, and increase freshwater recharge I. Introduction/Background The Indian River Lagoon (IRL) is a highly impaired water body as a result of excess nutrient inputs. In many areas these nutrients originate from urban areas being contributed at the surface through stormwater runoff and subsurface via Onsite Septic Disposal Systems (OSDS). Homes are being disconnected from septic systems and hooked up to centralized sewer collection systems to reduce this nutrient source. Typically, the septic tanks are abandoned by puncturing the bottom and filling them with sand or aggregate and left on site. This project proposes to repurpose septic tanks, which commonly have a volume of at least 1000 gallons, as cisterns that would either infiltrate into the subsurface or provide a supply for landscape irrigation, which has already successfully been done in the Florida Keys. This provides an additional benefit of the existing infrastructure to further reduce stormwater runoff volumes and loadings, increase groundwater recharge, and increase conservation. As sewer connections typically cost approximately $20,000, along with typically having a wastewater fee, many home owners are resistant to do so on their own. Utilizing an onsite cistern could reduce water and wastewater costs for homeowners, incentivizing them to proceed with sewer connection. II. Objectives 1) Coordinate with local government partners to identify and convert at least eight septic tanks planned for decommissioning to cisterns for capturing roof runoff that recover storage volume via infiltration or irrigation. 2) Evaluate water quantity and quality benefits of cistern conversions by regular monitoring and sampling at sites. 3) Develop and deliver an extension outreach program to educate citizens within the IRLNEP about septic systems, water reuse, and stormwater runoff. 4) Develop a publicly available tool for citizens and local governments to estimate runoff volume reductions, nutrient load reductions, and associated costs of converting septic tanks to cisterns. III. Location of Project In collaboration with Brevard County Department of Natural Resources and Martin County Utilities and Solid Waste Department, this project will target homes scheduled for septic to sewer conversion in Rockledge, Merritt Island, Palm Bay (Brevard County), and North River Shores (Martin County) communities. Extension education will occur throughout Brevard, Indian River, St. Lucie, and Martin counties. IV. Scope of Work Septic Tank Conversion to Cistern and Monitoring

9 In collaborate with Brevard County and Martin County agencies, this project will convert up to eight septic tanks to cisterns for rainwater harvesting. These will be residential properties undergoing sewer connection or otherwise decommissioning their septic tanks. Pre-conversion and post-conversion monitoring will be conducted at a minimum of one conversion home and one control site. Concentrations and flow data will be used to assess post-conversion nutrient loadings and load reductions compared to pre-conversion. Cistern water level records will be used to quantify volumetric runoff reductions and compare with runoff measurements from the site scale at cistern and control homes. For irrigating systems, irrigation volumes will be quantified to estimate potable water savings. Cistern Assessment Tool An excel spreadsheet tool will be developed to estimate the costs and benefits of converting septic tanks to cisterns. The tool will use contributing roof area, irrigable area, soil conditions, cistern volume, and utility rate structures to estimate long-term runoff volume reductions, nutrient loading reductions, water conservation, and costs. The tool will be based on long-term weather records to estimate rainfall and landscape irrigation needs and soil infiltration rates. While this tool will account for septic to cistern conversion, it will also assess implementation of new cistern and rainwater harvesting systems. This tool will provide home owners and local decision makers with valuable information to evaluate the benefits of septic tank conversion to cisterns. Extension Education Program Outreach programs will initially target homes in Brevard, and St. Lucie Counties septic-to-sewer conversion projects. At least 250 residents, county and municipality employees will increase their knowledge about 1) how OSDS may be a pollutant source and/or 2) beneficial reuse options by 75% as determined by post-survey evaluations. Of those, homes that have been previously identified for septicto-sewer conversion will receive one-on-one site visits. Outreach efforts will also include community educational efforts through the St. Lucie County Florida Yards & Neighborhoods Homeowner Program. These programs are expected to reach 250 residents as measured by site visit and workshop evaluations. These impacts are not inclusive of social media outreach including Facebook, IFAS blogs, and Twitter. Additionally, the project team will coordinate with Brevard County Department of Natural Resources, Martin County, and St. Lucie County Stormwater/Water Quality Division and relevant municipalities to introduce the cistern assessment tool and encourage participation within the reuse conversion program as part of current and future septic to sewer conversion and phase out projects.
