Exh 4CAGENDA ITEM #4C AUGUST 13, 2001 CITY OF ATLANTIC BEACH CITY COMMISSION MEETING STAFF REPORT AGENDA ITEM: Reclaimed Water Report SUBMTTTED BY: Donna Kaluzniak, Utility Director ~~ DATE: August 2, 2001 BACKGROUND: As part of the NPDES Permh Studies, Camp, Dresser & McKee (CDM) prepared a.Reuse Feasibility Study for both the Atlantic Beach and Buccaneer wastewater treatment plants. Reclaimed water is highly treated effiuent from a wastewater treatment facility that can be used for irrigation, aesthetics, industry or environmental enhancements. Potential reclaimed water users in our area include the Selva Marina golf course and the Mayport Navy Base golf course. If a reclaimed water system were constructed at the Atlantic Beach Wastewater Plant #1 (1100 Sandpiper Lane), this water could also be used for irrigation at Russell Park. Regulatory requirements fox reclaimed water are more stringent than our existing effiuent limitations, which would require capital improvements to the treatment plant(s). Additional capital would be needed to provide piping to the golf course(s). Operating costs would increase due to requirements for additional staffing, electrical costs and chemicals. A summary of the estimated capital and operating costs for alternative reclaimed water systems is as follows: Description Atlantic Beach Buccaneer WWTP Buccaneer WWTP WWTP #1 to Selva #2 to Selva Marina #2 to Navy Golf Marina Golf Course Golf Course Course *CapitalImprovements $639,450 $475,000 $475,000 to Treatment Plant **CapitalImprovements $472,500 $1,016,000 $533,000 _ pi Total Ca ital $1,111,951 $1,491,002 $1,008,002 Estimated Annual $10,000 $52,000 $52,000 O eratin Costs *Includes estimated amounts for engineering and. contingency. **Includes $105,000 for piping to Russell Park. AGENDA ITEM #4C AUGUST 13, 2001 Representatives of Selva Marina Golf Course have expressed an interest in obtaining reclaimed water from the City of Atlantic Beach. As shown above, capitat expenditures to construct the reclaimed water system would be considerable. Selva Marina currently uses water from the lagoon for irrigation, with an estimated cost of $0.03 per 1000 gallons. Based on CDM's analysis, the cost to provide reclaimed water from the City of Atlantic Beach would be approximately $1.00 per 1000 gallons, based on a 20-year financing period and assuming a 6.375 percent interest rate. This cost is based on providing the golf course with their average demand of 220,000 gallons per day. BUDGET: No funds aze being requested at this time. RECOMMENDATION: This report is provided for information purposes only. The City will provide copies of the Reuse Feasibility Study to the Selva Marina Golf Course, and Navy Public Works. ATTACHMENTS: 1. *Reuse Feasibility Letter Report from CDM, dated July 20, 2001. REVIEWED BY CITY MAN The full Reuse Feasibility Study Report for At~antic Beach Wastewater Treatment Plant is on file in the City Clerk's office, This is a lengthy document, and it is impractical to make copies.

This letter is intended to supplement the reuse feasibility study that was completed for the Atlantic Beach WWTP. This letter report will identify potential users of reclaimed water in the vicinity of the Buccaneer WWTP and identify the estimated costs to serve those users with reclaimed water. This evaluation will also identify potential sources of revenue that are available to aid in the construction of these facilities. Existing Facilities The Atlantic Beach Utility Department operates the Buccaneer WWTP. This facility is a 1.9 mgd ADF sequencing batch reactor wastewater treatment plant that discharges chlorinated/dechlorinated effluent to the Intracoastal Waterway byway of two vertical turbine effluent pumps. Space for new facilities at the plant site is limited, however the Utility Department has recenfly acquired additional property outside the existing WWTP fence. The existing chlorine contact chamber is sized to adequately provide a minimum of chlorine contact time of 15 minutes and is split into two redundant chambers that will provide Class I redundancy. Selected Reclaimed Water Application Sites The two most logical application sites to receive reclaimed water from the Buccaneer WWTP are the Selva Marina and Mayport Navy Base golf courses. These two points represent the largest nearby demands that would be feasible to deliver reclaimed water to. AGENDA ITEM #4C CDM Camp Dresser & McKee lu.;. AUGUST 13, 2001 Ms. Donna Kaluzniak July 6, tool Page 2 Representatives of the Selva Marinagolf course were contacted as pazt of the preparation of the Reuse Feasibility study for the Atlantic Beach W WTP. The Selva Marina golf course would be receptive to receiving reclaimed water. For this reason, it was included as a potential site for the Buccaneer W WTP. The Navy operates a golf course to the north of the Buccaneer W WTP. This course has the potential to accept reclaimed effluent should it be made available. This service could be extended to the Navy as part of an overall agreement to provide utility service. For this reason costs to deliver reclaimed water from the Buccaneer WWTP to point at the center of the golf courses was assumed to be a delivery point to an existing irrigation pond. Modifications to Provide Reclaimed Water Several on-site improvements would be necessary to supply the golf courses with reclaimed water that meets the requirements for public access irrigation. These improvements consist of a filtration unit, reclaimed water monitoring and control (flow, chlorine and turbidity), and modifications to the valves and controls of the effluent pumps to send the water to the golf courses or the existing discharge outfall. An evaluation was performed on the existing Buccaneer effluent pumps to determine if they would be adequate to deliver reclaimed water to the proposed golf course systems. System Capital Costs Table 1 provides a summary of the anticipated capital costs of the proposed reuse system. The capital costs for the on-site improvements is $430,000.00. The costs of the pipelines to serve the two golf courses is $1,550,000.00. (Navy $1,016,000.00, Setva Marina $533,000.00) System Operation and Maintenance Costs Tables 2 and 3 present the operation and maintenance cost differential for providing reclaimed water at the Atlantic Beach and Buccaneer WWTP's respectively. The additional costs for providing reuse aze $0.02 for the Atlantic Beach system and $0.16 for the Buccaneer system. The primary additional cost component is the anticipated additional labor required by the FDEP staffing requirements. System Production Costs Including Capital and O & M Using the preceding analysis and the capital costs developed for the system, a cost per thousand gallons of reclaimed water produced can be calculated. From discussions with the City, a payback period of 20 years was used for analysis. At an interest rate of 6.375 percent the capital costs for the proposed reuse system components at the Atlantic Beach and Buccaneer WWTPs were converted to a series of equal annual payments. These CDM Camp Dresser & McKee Inc. Ms. Donna Kaluzniak July 6, 2001 Page 3 AGENDA ITEM #4C AUGUST 13, 2001 payments and the additional operation and capital costs were used to calculate the cost to the City in dollars per thousand gallons of reclaimed water produced. This analysis is based on the current annual average flows to the plants and assumes that the City would be able to use all of its effluent as reclaimed water. Cost Per 1,000 allons of Reclaimed Water Produced Project Capital Cost per Operation and Total 1,000 Gallons Maintenance Cost per Cost per 1,000 1,000 Gallons Gallons Produced Atlantic Beach $0.18 $0.02 $0.20 Buccaneer WWTP $0.12 $0.16 $0.28 Selva Marina $0.25 $0.25 Pi eline (Buc) Mayport G.C. $0.13 $0.13 Pi eline (Buc) This analysis based on the break-even point assumes that the Golf Courses or other users can take all of the effluent from the wastewater plants. As detailed in the earlier Reuse Feasibility study for the Atlantic Beach WWTP, the Selva Marina golf course currently uses 0.22 million gallons of water per day. Reclaimed water, like any commodity is subject to the pressures of supply and demand. Although the production costs are attractive at the Atlantic Beach WWTP, based on the limited amount of demand for reclaimed water, the price to break even would need to be increased to the $1.00 per 1,000-gallon rate as detailed in the Reuse Feasibility Study. Until such time as the economics change in favor of utilizing reclaimed water, either by an increased demand or a reduction in the quality of stormwater for irrigation use, the city would be required to subsidize the cost of implementation of a reclaimed water system Potential Sources of Additional Funding Additional funds for the construction of reclaimed water facilities are available through the several state programs. The first source that the Utility Department should explore is the St. Johns River Water Management Districts Alternative W ater Supply Construction Cost Sharing Grant Program. This program provides up to a 50 percent share of construction related expenses for projects that can demonstrate a reduction in potable water use that would be realized by the project. Awards are based on the amount of available funding and number of projects that are awarded grants. The total funded capacity of this grant usually limits this grant to a range Of $75,000 to $100,000 per award. AGENDA ITEM #4C C©M Camp Dresser & McKee Inc. AUGUST 13, 2001 Ms. Donna Kaluzniak July 6, 2001 Page 4 Another source of alternative funding is byway of the Florida Department of Environmental Protections State Revolving Loan program This program funds wastewater related construction projects utilizing low interest (3 to 4) percent loans.
