If the bottom of the scum layer is within 3 inches of the bottom of the outlet baffle or the top of the sludge layer is within 12 inches of the outlet baffle, your tank needs to be pumped. Whether or not the pumper determines the tank should be pumped, sludge and scum levels should be noted in your operation and maintenance records. This information will help you decide how often pumping is necessary.		The contents of the tank should be pumped through the main lids only, not through the baffles. Everything should be removed out of every compartment; 'starter' is not needed to reactivate the tank.    In the service report, the pumper should note whether the tank is in good condition or damaged. Any repairs made by the pumper during this visit should be recorded. If the pumper recommends repair but cannot perform this service, note the recommendation and hire someone to make the repairs as soon as possible.
