1-1 Other
Unknown; or a combination of the above factors. It is not always possible
to determine the exact cause of system failure, but those listed are
common factors.
2. Tanks - City Code %equ Aes 2 .tanks .in a normat nes.identiae gray.c ty-6tow system:
1-1000 gatton, 1-750 gatfon precast concAe-te -tanks .in seni.es. These aAe minimum
sizes - you may wish to instatt taAger tanks. 16 you have onty 1.tank, it--"
noAmatty requ Aed to add a second when %epaiAi.nc, a 6a.iting system. 16 you have
2 .tanks but they aAe substantiatty undmized (500-600 gateons, bon instance),
it .is recommended that .they be reptaced. 16 youA %epaiAs wits %equiAe a pump,
it shoutd be ptaeed .in a thvcd .lank (500-1000 gateon recommended).
aSystem will likely require replacement/addition of 1 or more
tanks:
3. A note about pumps: Pumps and pump eontAots have out o6 necessity become betteA
designed and more duAabte in .the tact hew years. Neatey one septic system .in
6ouA instateed .in Orono makes use o6 a pum;-, due to site conditions. A pump may
be needed: - when basement 6toor dAa.ins or towest sewer tine are betow .the aAea
to be used as dnain6ietd. - in att mound systems, which cute used wheAe high water
tabte or stowty pereotati.ng zoitz are bound.
There ate ess enti.att y .two -types 06 pumps used .in septic systems appt.icat ions .
1. E66tuent pumps - pump onty t.iquids, normatty used a6teA the second septic
.tank, or 604 taundAy .in .the basement; and
2. Gn i.ndeA or s ot.id6 - handt i.ng pumps, used 6oA basement .toi t e is and sometimes
.instatC.ed in an outside sump, -hich pump sewage up to septic .tanks on
high ground.
Pump 6aiC.uAes .in .the past have been due mostty `o switch 6aituAes (eonAos.ion
or weaA.ing out) and etectni.c connection corrosion. Both o6 these probtems
have been reduced by use o6 eo4Aos.ion-4e.6istent 6toat switches and connection
boxes. White pump 6ai.tuAes aAe tens common than in the past, a high water
atahm costing approx,i.mateey $75-$100 is nonmatty %egUi,Aed wheAe a pump .ch used.
It's wett worth the price 16 it saves you a eostty basement cteanup.
FlRepairs to system will likely require a pump, including a pump tank
