:his lot was previously tested by us on October 1-11, 1919 for
a proposed house t'iat was never constructed. Six percolation holes
Were te3te3d at that time and three soil borings taken in an area
that is stil ;7snbl:� for a drainfileld site. The percolation holes
were dvf- i n- .,.e.s ce •r and 6 incL-e3 in dia►-.ete -, the ,.oil
borings were inches In diamoter to the 1� foot depth and 3 in-
ches in dianetor to the & foot depth.
5a results are shown on the next page with the average per-
colation rate for the b holes being 50.4 ninutes per inch. One hole
had a much slower rate probably because of its location near a
shall scale. ene drainfiald should be kept to the north to avoid
tiAs area and also allow more root. for the house and driveway to be
built. Since the soil appeared well drained and no evidence of a
higa water table existed, a standard grainfield system could be used
for both the primary and alternate sites.
For the proro:�ed 3 bedroom hou:;e the estimated sewage flow is
`0-450 ia. lons .,or day. :'ith an average percolation r//e of 50 minutes
