Pump Tank Sizing <br /> Assuming a pump height of 20" and a tank with 125 gallons per inch: <br /> Pump submergence volume =2500 Gallons <br /> Dosing Volume =429 <br /> Equalization Volume = 5142 Gallons <br /> Emergency Storage Volume = 3000 Gallons *(highest daily flow) <br /> Adding the volumes yields a required dosing/equalization tank volume of 11,071 <br /> Gallons. <br /> Dosing Regime: 429 gallons every 8 hours. Given a measured pump delivery rate <br /> of 50 gpm. The repeat cycle timer would be set at 8.6 minutes "on" and 8 hours <br /> (or 7.86 hours) "off'. <br /> VI. Installation and Testing Procedures: <br /> a. A pre-construction conference shall be required to be attended by the system <br /> designer, installer, local health department, licensed soil scientist and registered <br /> professional engineer, as applicable, prior to beginning construction of the flow <br /> equalization system. <br /> b. The septic tank, dosing tank, risers, and pipe penetrations shall be demonstrated to <br /> be watertight by a 24-hour leak test(no measurable leakage in 24 hours). The test <br /> shall be run with risers and inlet/outlet pipes installed. <br /> c. Care shall be taken during system installation to prevent extraneous debris from <br /> entering the tanks, supply lines or distribution network. Supply lines, manifolds <br /> and orifice control devices shall be flushed out prior to system startup. <br /> d. A pump delivery rate shall be measured and the timer control device adjusted <br /> according to the measured delivery rate to achieve the equalized daily flow. The <br /> time dosing control panel manufacturer's recommendations shall be followed for <br /> system start-up. The timer control device shall be setup per the system design <br /> specifications in accordance with the measured pump delivery rate by the operator <br /> in responsible charge (ORC). All floats, counters, meters, timers, and alarms shall <br /> be tested for functionality. If needed the control panel manufacturer's <br /> representative shall be present during system start-up. <br /> e. All other mechanical components, pump(s), pump cycling, filters, etc., as <br /> applicable must be demonstrated to be fully operable in accordance with their <br /> design. <br /> 9 <br /> 109 <br />
