Fort Walton Beach Resolution — 2008-10-Adopting 2008 EAR — reading text

previously, the City places a great deal of emphasis on public education and public outreach programs to infonn citizens of various water conservation measures and water reduction the City by programs. These programs, while expensive to implement, provide an indirect benefit to promoting wise and efficient use of the community water supply. However, the total volume of inefficient use of the water system through the implementation of these programs is difficult to quantify. REGIONAL WATER SUPPLY PLAN 35 CITY OF FORT WALTON BEACH  As part of the City's Public Education campaign, the Utilities Department began offering Water Saver Kits to citizens upon request several years ago. These kits contain several devices to conserve water in the home including toilet tank displacement bags, leak detection tablets, replacement showerheads, water faucet aerators, and conservation tips. Collectively when installe~ these devices can reduce household water consumption by 100 gallons, or more, per day. Customers that call regarding abnonnally high water bills or those wishing to reduce their nonnal monthly consumption are offered these kits as an incentive to reduce their monthly expense for water use. Though public education is very important, its impact is not included in the preparation of future water production needs. 6. 7 PLUMBING CODE REVISIONS In 1992, the federal government established National Water Efficiency Requirements for plumbing products with the passage of the Federal Energy Policy Act. Almost every toilet, urinal, shower head and faucet manufactured after January 1, 1994 must meet Uniform National Conservation Standards. The Southern Standard Plumbing Code allowed two years for supply houses to clear inventories of old style fixtures. As of January 1, 1996 all new or renovated buildings must install fixtures meeting the new standards. Residential water savings from retrofitting conventional toilets, showerheads, and faucets range from 13. 5 gpcd for replacement of fixtures installed after 1980 to 33. 5 gpcd for pre- 1980 fixtures. Reductions in water demand from more efficient plumbing fixture usage over the next 25 to 40 years will be continuing and incremental as existing high-volume equipment is replaced with new, more efficient models. Per capita residential use from faucets, showerheads, and commodes is projecte~ on a national average, to drop from 45 gpcd in 1995 to 21 gpcd by 2026 (Vickers, 1993). As of January 1, 1996, all new or renovated buildings must install plumbing fixtures that meet the new standards. These new efficient plumbing devices will certainly lessen the impact of new construction on potable water demands, however, given the fact that the City expects very limited new construction in the next ten years, any reductions in future water production needs would be minimal. SECTION 7 - WATER SUPPLY NEEDS The City of Fort Walton Beach maintains records of raw water withdrawals and metered consumption on a monthly basis each year. The following table indicates the raw water withdrawals and metered consumption from 2000 to 2007.

As noted in Table X,the actual average level of service provided by the City' s water system is less than the standard level of service, allowing a " safety factor" for future planning. 7. 1 FUTURE WATER NEEDS PROJECTIONS Based on the projected annual growth rate of 0.70 percent per year and the withdrawal rates and production from 2007, the future raw water withdrawal and treated water production needs were projected from 2008 through 2017 ( See Table XI). 1thdrawal & T reate dWater Pod T able .XI Future Raw W ater w. r ucUon Pr01ecuon . s Future Raw Water Withdrawals Future Treated Water Production Average Maximum Maximum Average Maximum Maximum YEAR Day Day Month Day Day Month 2008 2, 917, 000 3, 929,000 103, 969,000 2, 891, 000 3, 887,000 103,431, 000 2009 2, 938, 000 3, 957,000 104, 697, 000 2, 911, 000 3, 914,000 104, 155,000 2010 2, 958,000 3, 985, 000 105,429, 000 2,932,000 3, 942,000 104,884,000 2011 2,979,000 4,012,000 106, 167, 000 2,952,000 3, 969,000 105, 618,000 2012 3,000,000 4,040,000 106,911, 000 2,973, 000 3, 997,000 106,358,000 2013 3,021, 000 4,069,000 107, 659, 000 2, 994,000 4,025,000 107, 102,000 2014 3,042,000 4,097, 000 108,413, 000 3, 015,000 4,053, 000 107, 852,000 2015 3, 063, 000 4, 126, 000 109, 171, 000 3, 036,000 4,082,000 108,607, 000 2016 3, 085,000 4, 155, 000 109, 936, 000 3, 057,000 4, 110,000 109,367, 000 2017 3, 106,000 4, 184,000 110, 705,000 3, 078,000 4, 139,000 110, 133,000 REGIONAL WA1ER SUPPLY PLAN 37 CITY OF FORT WALTON BEACH  Through the year 2017, the City' s water system has the capacity to provide sufficient potable water from the Roridan aquifer. At this time, there is no need to increase current production levels at any of the existing water wells. In the latest CUP renewal application, the City did request an increase in the Maximum Monthly Rate of Withdrawal (MMR) from 120 million gallons per month to 125 million gallons per month based on the 2006 withdrawal rates. The 2006 withdrawal rates were much higher than average due to the drought conditions the area experienced. In 2007, the withdrawal rates returned to below average conditions. The average daily demand for the ten year projection was detennined by utilizing the withdrawal rates from 2007 and adjusting the rates by the 0.70 percent annual growth rate each year to 2017. The average daily demand in 2007 was 2, 897,000 gallons per day, and the average daily demand projected for 2017 is 3, 106, 000 gallons per day. A surplus of 494,000 gallons per day will exist in the City' s CUP withdrawal limit. The surplus would be capable of serving an additional 3,290 persons using the standard level of service of 150 gallons per capita per day. SECTION 8 - WATER STORAGE AND DISTRIBUTION SYSTEM NEEDS The ability of the City' s existing system to meet both current and future water supply needs can be assessed by reviewing the current and future demands versus the supply capacity of the City's nine wells. The limitation of the City' s existing system is not the wells or the equipment, it is the withdrawal rate limits imposed by the NWFWMD as part of the Consumptive Use Permit. The City's existing system is capable of providing over 9. 2 million gallons of potable water per day. However, the CUP limits the system to 3. 60 million gallons per day on an
