August 9, 1977 Pitkin County Environmental Health Dept. 506 East Main Street Aspen, Colorado 81611 Attention: Mr. Bob Nelson Re: Paul Rubin Residence, E/T System Inspection Lot 6, Capitol Woods Subdivision Our File No. 77137 Dear Bob: On August 5, 1977, I inspected the above referenced system and found same to be in substantial conformance to our plans and standard E/T system construction practice. The system was com- plete to the point that the sand layer over the distribution lines and some topsoil were in place. I assume you will make the final inspection of topsoil, seeding and air vent lids. For the record, I note that the "As -Built" bed dimensions were approximately 40' x 45' (1800 S.F.) rather than the proposed 55' x 31' (1705 S.F.) but the required bed area was more than adequate. Just a general note regarding the P.V.C. tee inlets and outlets. I share your concern regarding possible damage. If not from sur- face loads there is a good chance that the C.I.P. settlement could cause the tee bell to split, crack, or break in time. I believe I would require either C.I.P. tees or more support for the P.V.C. tees. On this particular system I would caution the builder/owner to be sure there is adequate supporting backfill under that inlet tee. ;Very truly urs, H.L. Graham P.E. and L.S. cc: Mr. Paul Rubin ■ 1`000 .n ,c- ir-7/C TAN < 1 114 I 0 V4 rQ ii -3 m ad t <+' 4 ;r- ,�: �FE --rp 4 4 -r 121 S "' 1,1—::3 C.., 7710q P}, 4E3El5Jp .-rap f� EVAP0 -T AJ5F1 r,4-r/0th ` J +-V 00 7' r I r t c a e r Fi c - 4/Z } 14 o 11 ! rV'1,� L.
