Lyon, R.S. <br />4s-lw-2D TL ¢600; Site #95-14850 <br />Columbia Aeronautics Association Clubhouse; <br /> <br />Aurora, Or. <br /> <br /> Hello Bob, thank you for your consideration of these new test <br />pits, please find the soils work sheet enclosed. Zf we agree a <br />capping fill drainfield will work in these soils, there will be <br />room for over 1,500 Lf. We could use a redundant configuration to <br />include the repair. Of course this will need to be staked out <br />later, we are only requesting a conceptual design & soil sizing <br />approval at this point. <br /> <br /> We also have enclosed water use data from 1988 to Hay 1995. <br />The average use is 299 GPD, but this is actually high due to the <br />faulty plumbing...note the usage when the building was vacant. <br />From this and the fact that they will only use the facility once a <br />week where -65 members attend (215 members) we propose using the <br />Airport sizing of 5 gallons per person listed in Table 2 of the <br />D.E.Q. rules. These ideas are certainly open to modification as you <br />see fit, actual water usage is probably going to be less than ~200 <br />GPD, maybe metering flow can be incorporated. We look forward to <br />discussing this further at your convenience. <br /> Again, thank you in advance for your careful attention in <br />this matter, I hope this provides some help, If you have questions <br />feel free to call at 265-8826. <br /> <br />Richard E.
