The submitted data shall consist of at least 12 <br /> previous consecutive monthly total water consumption readings and at least 30 consecutive daily water <br /> consumption readings. The daily readings shall be taken during a projected normal or above normal <br /> sewage flow month. A peaking factor shall be derived by dividing the highest monthly flow as <br /> indicated from the 12 monthly readings by the sum of the 30 consecutive daily water consumption <br /> readings. The adjusted design daily sewage flow shall be determined by taking the numerical average <br /> of the greatest ten percent of the daily readings and multiplying by the peaking factor. Further <br /> adjustments shall be made in design sewage flow rate used for sizing nitrification fields and <br /> pretreatment systems when the sampled or projected wastewater characteristics exceed those of <br /> domestic sewage,such as wastewater from restaurants or meat markets. <br /> (2) An adjusted daily sewage flow rate may be granted contingent upon use of extreme water-conserving <br /> fixtures, such as toilets which use 1.6 gallons per flush or less,spring-loaded faucets with flow rates of <br /> one gallon per minute or less, and showerheads with flow rates of two gallons per minute or less. The <br /> amount of sewage flow rate reduction shall be determined by the local health department and the State <br /> based upon the type of fixtures and documentation of the amount of flow reduction to be expected <br /> from the proposed facility. Adjusted daily flow rates based upon use of water-conserving fixtures shall <br /> apply only to design capacity requirements of dosing and distribution systems and nitrification fields. <br /> Minimum pretreatment capacities shall be determined by the design flow rate of Table I of this Rule. <br /> History Note: Authority G.S. 130A-335(e); <br /> Eff.July 1, 1982; <br /> Amended Eff.January 1, 1990;January 1, 1984. <br /> 15A NCAC 18A.1950 LOCATION OF SANITARY SEWAGE SYSTEMS <br /> 100 <br /> 21 <br />
