Inspection Report: Septic System Serving 3125 Pox Street
I inspected this system on August 2, 1984, and wish to make the
following observations:
1. The house is served by one known septic tank of approximately
750 gallons capacity. It is possible but not likely that a second
tank exists. Orono has required two-tank system since 1961—this
system probably predates that time.
2. Our records indicate repair work done in 1967, which according
to Mr. Gibbs was addition of drainfield. I could not verify the
actual amount of drainfield existing, but if there are three lines
as Mr. Gibbs seems to remember, there might be as much as 500 or 600
square feet. This would likely be less drainfield than is
normally installed for a house of this size today.
3. The existing drainfield shows no evidence of current or past
discharge, and from this I infer it is adequately handling the
current effluent load. Should the effluent load increase
appreciably, it is not possible to accurately predict on the
sketchy specs available, how this would function.
4. The existing septic tank appeared to need pumpout at this
time. I noted a fairly thick layer of solids in probing the tank.
I would also suggest that to do a thorough job of cleaning and
maintaining this sytem, the tank should actually be uncovered,
solids pumped out, and baffles checked and replaced if necessary.
I would also recommend that, due to the depth of this tank below the
surface and the need for strict and judicious maintenance since
there is only one tank, it would be wise to replace the tank cover if
necessary and add a 20” manhole to the surface so the solids can be
adequately stirred and removed.
5. This property is about seven acres and has ample room to expand
the system should it ever be necessary.
