It is not always possible <br />to determine the exact cause of system failure, but those listed are <br />common factors. . <br />2. Tanks - City Code requites 2 tanks in a nonmat taidenti.at g4avity-6Zow system: <br />1-1000 gatl.on, 1-750 gaZton precast concrete tanks in smi.es.

A note about pumps: Pumps and pump eonttots have out 06 necessity become better <br />designed and none dutabte in the last hew yewes. Neahly one septic system .in <br />bout .insta.Pted .in Ouno makes use o6 a pump, due to site conditions. A pump may <br />be needed: - when basement 6toon dta ns on lowest seven sine ate below the area <br />to be used as d4ain6ietd. - .in aU mound systems, which ate used where high water <br />table on slowly peneotating soils ate bound. <br />There are essentiaUy two types o6 pumps used in septic systems appPi.cations: <br />1. 666tuent pumps - pump only Zi.qu,ids, no�unaUy used a6tet the second septic <br />tank, on bon taundty .in the basement; and <br />2.
