-^1 <br />TO:Alan P. Olson, City Planner <br />FROM:Michael P. Gaffron, Septic System Inspector <br />DATE:April 6, 1982 <br />SUBJECT: Northern Avenue, Septic Systems Review <br />Northern Avenue is an unsewered street in the sewered area of <br />Orono, and is one of two such remaining areas of the City <br />surrounded by adjacent sewered properties. Six residences are <br />served by five septic systems on Northern Avenue, with an additional <br />residence near Togo Road having sewer stub available but needing <br />an easement over another property to make the connection. <br />Although all the existing systems are substandard, no failures <br />have been recorded and the residents have done a fairly good <br />job of keeping their systems operable. <br />A review of each existing system follows: <br />3590 Northern Avenue - Small residence on .27 acre lotc System <br />has two tanks and a drainfield. No surfacing observed during <br />inspection of lot in 1979. House is connected to City water. Not <br />much room to expand system should it fail, however. <br />3640 Northern Avenue - System consists of one (maybe 2) tanks <br />with drainfield. House sits on 0.60 ac: e lot with •** acre vacant <br />lot with storage building adjacent. No record of prcolems with <br />the system. Some room for expansion of drainfield exists. <br />Connected to City water. <br />3670 Northern Avenue - House on 0.44 acre lot. Added second <br />tank and new drainfield in 1978. No record of problems since <br />then. Connected to City water. Not much room for future <br />expansion of system if needed. <br />3680 Northern Avenue - House sits on 0.69 lot. System has <br />one (maybe two) tanks and a bed drainfield. No record of failure. <br />Still using well water. Some room exists for future expansion <br />if necessary. <br />^690-3700 Northern Avenue - These two houses are connected to <br />a single septic system consisting of a 20'+ deep cistern-type <br />septic tank and an unknown length of drainfield. This system <br />was not failing during my last inspection, but because of its <br />design it is extermely substandard. The two houses are located <br />in the southwest portion of a 5 acre + tract. Ample room for <br />system expansion is available. The houses are connected to City <br />water. <br />mar riffc^‘rr»ft ^ •
