THE FOLLOWING GUIDELINES SHOULD HELP YOU IN REPAIRING YOURFAILING SEPTIC
SYSTEM:
1. System is 6aif ing because:
? Poor soil conditions
Too much water use for size of system
High water table.
aSludge getting into drainfield - tanks need repair/replacement
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 %equiAes 2 tanks .in a nonmat nes.identiat gnay.ity-6.tow system:
1-1000 gaUon, 1-750 gallon precast eonchete tanks .in 6eni.e6. These she minimum
sizes - you may wish to in6taU .ta&gen tanks. 16 you have only 1 .tank, iT'.0
no)unaGty neguited to add a second when nepaiAing a 6aiti.ng system. I6 you have
2 .tanks but .they ahe zubstantcatty undeuized (504-600 gatt.ons, bon .instance),
it is recommended that .they be tepZaced. 16 youh %epaiu w;_U tequiAe a pump,
outd be ptaeed .in a th,ihd tank (500-1000 gatton recommended).

3. A note about pumps: Pumps and pump contnotz have out o6 necessity become better
designed and move duhab.te .in .the .tact hew yewL.6. Nea ty one septic system .in
6ouh .instaUed .in Ouno makes use o6 a pump, due to site conditions. A pump may
be needed: - when basement 61-oon d4a,i.n6 on Zowest seweh tine are betow .the area
to be used as d4a.i.n6.ie.td. - .in aU mound systems, which are used wheAe high wateh
tab.te on sZowty peheo.tati.ng zo.c s ahe bound.
There are ess enti.atty two types o6 pumps used .in septic systems app.ei.cations :
1. E66tuent pumps - pump on.ty ti.quid6, nohmatty used a6ten the second septic
tank, on bon .taundhy in .the basement; and
2. Gni.ndeA on 4oZi.ds-handting pumps, used bon basement toitets and sometimes
.instaP,ted in an outside sump, which pump sewage up to septic -tanks on
high ground.
Pump 6altuhe6 .in the past have been due mo6.tty to switch 6aiewces (co%vco,6ion
on weati,ng out) and etectAi.e connection conhos.ion. Both o6 these p4ob.tem6
have been reduced by use 66 eonhos.ion-nez ,6tent 6.toat 6w,c tche.a and connection
boxes. White pump 6ac.tuhes she .tes6 common than .in the past, a high water
a.taAm costing appnox,i.matety $75-$100 is nonmatty hequveed whehe a pump is used.
It's wett worth the phice i6 it Eaves you a co6tty basement cteanup.
IJRepairs to system will likely require a pump, including a pump tank
and alarm system.
