Attention: Mr. John Lynn
Dear Mr. Lynn:
Subject: On Site Waste Water Disposal System for Tract D-2, Woodhaven Addition
Attached please find a copy of Alaska Test Labs report regarding the above
mentioned project. The report outlines-that within the five acre tract, 4
test holes were drilled and one percolation test performed within test hole
3A. The percolation rate measured 30 minutes per inch.
In addition to t, he~rilled test holes, a backhoe pit was dug by Mr. Bill
Prosser to a depth of 18 ~eet on March 16, 1981, approximately 100 feet sou~th~.
· e__~rly of test hole 3~k~T_b~hole was left open ove~ night and in~pecte~ ~e
following day. No water table was observed.
' in reviewi~gthe teS~ report, the sit'conditions and the proposed usage
' of the five acre tract as a church site, It appears that an adequate location
for an~ite septic disRosal system and a replacement drain field is available.
It is recommended that the system be designed in accordance with Part
II of the Manual of "Septic-tank Practice", U.S. Dept. of Health, Education
& Welfare, Septic-tank Systems for Institutions, Recreational Areas and other
establishments. It is also recommended that the seepage trenches be inspected
p~ior to installing the system in order to adjust the final desi§n to actual
conditions encountered.
