This system consists of a 1,000 gallon concrete tank and 375' of drainfield with a curtain drain above <br /> the drainfield. The tank and the drop boxes are currently uncovered, and the system appears to be in good <br /> working condition. <br /> Proposed: I have laid out both initial and replacement areas, with three additional test holes within these <br /> .areas. The original evaluation by Bob Foster required 125' LF of drainfield for each 150 GPD of effluent. <br /> Based on DEQ's factor of 5 gallons per seat per day the required lineal footage for 200 seats is 833.33'. <br /> Using these factors, I have laid out a total of 1,735 LF of drainfield as shown on the drawings. The initial area <br /> is utilizing 326' of the existing drainfield and adding the remainder down slope of the existing system. The <br /> existing tank is to be abandoned. <br /> Please call me if you have questions. <br /> Thank You, <br /> Todd Z. <br /> 503-991-6578 <br />
