ON-SITE SEWAGE TREATMENT - REPAIRS OR ADDITIONS TO EXISTING SYSTEMS
THE FOLLOWING GUIDELINES SHOULD HELP YOU IN REPAIRING YOURFAILING SEPTIC
SYSTEM:
1. System is 6aifi.ng because:
❑ Poor soil conditions
F] Too much water use for size of system
F1 High Water table.
Sludge getting into drainfield - tanks need repair/replacement

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 requites 2 tanks ,in a notmat ncs.ide,ttint g•tay.i.ty-6£oa, system:
1-1000 gaUon, 1-750 gatton precast conc.%e.te ,tanks in se -ties. Thcse ate mi►ti►rttm

3. A note about pumps: Pumps and pump coatof.5 have out o6 nece-6.5ity become bette,t
de.s.igned and more dtitabtc in .the tast bete yeau. Neatty one septic system .in
hour, .installed .in Unono makes use o6 a pump, due to ai-te conditions. A pump may
be needed: - Aen basement 6toon dna.ins on toacest ze;v n fine arc b. tote th,: arca
to be used a„5 dtain6ietd. - .in att mound systems, avhich ate used t0ine high ttutet
tabte on atctrty pncotating aoi,ts ate 6ou►td.
There cute essentially tiro types on' pumps used .in septic systems appLications:
1. F66tuett ptumpa - pump onto tiquZds, nonmat•£y used a6.tn the second septic
tank, on 6or taundty in the basement; and
2. G't,inden wt sotids-handt.ing pumps, used 6o•t basement toc,tcts and sometfine.5
•i►tataf£ed in an outside sump, which pump seirage up to septic to -,U on
high ground.
Pump 6aiP.utes .in the past have been due mostty to s,ei,tch 6aituAcs (cn•vtos.ion
on weaAi.ng out) and etect�tic connection conh.oa.ion. Both o6 these ptobtems
have been reduced by use 06 co4Aoaion-,'tUiatent 6toat bwi,tchea and connection
boxes. White pump 6aituAee a,te tela common than in the past, a high tuate.t
ataAm costing appnox.&na,tety $75-'100 .is no•tma.tty nrqu.iAed t4ine a pump iz used.
It's weft w 4th the pt,ice .i6 it saves you a coAtty basement c.tcanup.
F] Repairs to system will likely require a pump, including a pump tank
and alarm system.

F1No Recommendation on system type; you should have soil testing done and have
a system designed by a site evaluator, site conditions are too marginal or
unknown to make a reasonable recommendation without testing.
