(or 90 ft.x 135ft.) <br /> The leach pits also require the following setbacks; <br /> a. Property line—75 feet <br /> b. Storm pond deeper than 6 feet—100 feet(10 feet for ponds< 6 feet deep) <br /> c. Onsite water wells-150 feet <br /> d. Buildings- 10 feet <br /> 6. Domestic and Fire Suppression Water <br /> Offsite water services are not available at this site.The site can be served by a well and storage tank <br /> system.A well exists onsite, however,the size, performance and viability of this well are unknown at <br /> this time. <br /> For domestic, potable use,State and County water quality standards must be met to utilize this <br /> water system. <br /> Based on our preliminary findings, in order to utilize an onsite water well for fire protection, one of <br /> two alternatives must be provided; <br /> a. An onsite well and back-up generator system capable of producing 1,500 gallons per minute <br /> (gpm)• <br /> b. In accordance with NFPA 1142, an onsite storage tank with a 115,000 gallon capacity(for Type <br /> VB Building) and associated fire pumping system capable of pumping 1,000 gpm.This is roughly <br /> a 30 foot diameter by a 24 foot high tank.The tank size can be reduced to 77,000 gallons for a <br /> Type 1116 building. <br /> The storage tank is generally the more economical option for this type of site. eROF ESS/oV <br /> cl <br /> N0. 0-3 <br /> EXP. 12/31/191/19 <br /> r <br /> Anth yJ.
