Hamilton County Public Health inspects septic systems

Hamilton County Public Health inspects septic systems throughout   Hamilton     County with the exception of Cincinnati Norwood, Springdale, Sharonville (we now serve Sharonville) and     Indian Hill .This video shows just one example of a system we may encounter.     which in this case is an Oldham Aerobic Treatment Unit or ATU for short A     technician in our Water Quality Division recently inspected this system in Green     Township In a  gallon per day Oldham system there are four lids leading to     different chambers of treatment within the system. The first access lid     typically contains an inner lid which helps keep odors to a minimum because     this chamber is where raw waste water is stored during the settling and     separation phase of treatment Here the technician is looking for proper baffles     signs of infiltration and obvious need for pumping ATUs should be pumped     every two to three years with normal usage of less than  gallons per day.

The resulting clear effluent from the first compartment moves into the second     compartment of the tank The second compartment is the aeration chamber     where a majority of the treatment happens On an Oldham system there is     typically a light on top of the lid that covers this compartment the light turns     on to notify the system owner if the motor on the ATU is not in working order     The riser over the second compartment houses the aeration blower and timer     This system has a timer that is not approved but according to Health     District records has existed in the system for many years; the next time the     system owner replaces the timer it will have to be replaced with an approved     timer System owners should always verify with the health district that sub]]     replacement parts such as aerators and timers are approved prior to purchasing     replacement parts It is customary for our inspectors to switch the aerator on     to verify the system is working correctly as the technician does here     the technician is looking for many signs of problems here such as foul odor     incorrect timer setting and clogged or broken Airlines Effluent leaving the     second compartment enters the clarifying chamber where final settling of any     solids or floatables are separated and returned back to the aeration chamber In     this system that is accomplished by mechanical skimmer when the system is     actively aerating and by gravity settling when the aerator is in its rest     cycle Not all Olham systems have mechanical skimmers In systems without a     mechanical skimmer floatables are trapped in the third compartment by the     outlet baffle and must be removed manually by a registered contractor on a     routine basis Most ATUs need to be serviced at least every six months     Amongst other things the technician is looking for signs of proper service and     a working baffle when inspecting this compartment Under the fourth lid the     technician gains access to a separate chamber that is actually a completely     different tank called an upflow filter As the name implies here the effluent is     filtered through a gravel bed where final polishing happens In Oldham     systems the up flow filter is aerated to improve effluent quality Again the     technician looks for signs of infiltration, poor effluent quality,     proper aeration, and signs of effluent or the filter being bypassed The technician     also ensures that the up flow filter contains chlorine to kill up any     pathogenic bacteria prior to the effluent being discharged to the     environment Once the technician is finished inspecting the system he fills     out the proper paperwork and uploads it to the Health District databases The     system owner will typically receive the inspection results and associated     invoice within a few business days For more information on septic system     inspections go to HERE
