However, we do know the number and type of existing fixtures, as well as the proposed fixture <br /> types to be installed in the Hospitality Room. Therefore,the only plausible scientific method to <br /> estimate flow volumes without knowing the number of people, is to estimate flow volumes under <br /> "worst-case scenario" conditions based on fixtures. <br /> The following is an itemization of the existing and future fixture units within the Clubhouse/Future <br /> Hospitality Room: <br /> Existing;Men's RR: Existing Women's RR: Existing Office RR: <br /> 1 Toilet/Stalls 3 Toilets/Stalls 1 Toilet <br /> 2 Urinals 3 Sinks 1 Sink <br /> 3 Sinks <br /> Future Fixtures: <br /> 1 Bar Sink <br /> 1 Triple (3 Compartment) Sink <br /> 1 Hand Sink <br /> Estimating a fixture usage of one use, every ten minutes (excluding the Office RR since this is <br /> private and rarely used) over an 8-hour time period,we find the following: <br /> Men's RR: <br /> 1 Toilets/Stalls x 2 gals/use(1.6 gpf+0.4 gals sink hand wash)=2 gals/use x 6 uses/hr x 8 hrs=96 gals <br /> 2 Urinals x 1.4 gals/use(1.0 gpf+0.4 gals sink hand wash)=2.8 gals/use x 6 uses/hr x 8 hrs= 134 gals <br /> Women's RR: <br /> 3 Toilets/Stalls x 2 gals/use(1.6 gpf+0.4 gals sink hand wash)=6 gals/use x 6 uses/hr x 8 hrs=288 gals <br /> 2 Urinals x 1.4 gals/use(1.0 gpf+0.4 gals sink hand wash)=2.8 gals/use x 6 uses/hr x 8 hrs= 134 gals <br /> Estimated flow volumes for the future Hospitality Room Sinks are somewhat more difficult to <br /> project. However, we will use 10 gallons/sink/hr: <br /> 3 sinks x 10 gals/hr/sink= 30 gals/hr x 8 hrs=240 gals <br /> Therefore, a projected Average Daily Flow(ADF) from the existing and proposed expansion = <br /> 96+ 134 + 288 + 134 + 240 = 892 gals/day <br /> Wastewater Flow Characteristics <br /> T d_pre os itabl Room is to be designated as a"Catering Kitchen." <br /> ere will ben king within the entire�facility; food will be brought in, with on-site warming <br /> ovens to keep food warm. oo wasted must be, handled as solid wastes and <br /> disposed of in the trash. Therefore, there should be no concentrated organic loading. The <br /> characteristics of the wastewater flow will be blackwater from toilets, with smaller volume of <br /> graywater from the sinks. Additional wastewater constituents may consist of alcoholic drinks, <br /> coffee,juices or other similar type liquids to the system. No industrial or commercial chemicals, <br /> solvents, etc. are to be introduced into the septic system. <br /> Chesney Consulting <br />
