The condition of the baffles should be checked when the tank is being pumped. Replace those in poor condition with sanitary tees. Any repair or new installation of a septic system must be approved by the local sanitarian and a permit issued by the local health department. Water conservation reduces the amount of water the absorption field must accept. It also reduces the flow through the septic tank allowing more time for solids to settle out.
Water conservation can prolong the life of any soil absorption system.
Installing an alternate soil absorption field involves constructing a second soil absorption system and diverting all of the wastewater to it for at least one year to rest the original field. The fields can then be alternated. Repair physical damage such as leveling the distribution box or repairing crushed or broken pipe to restore the system. Tree roots interfering with the operation of the soil absorption field must be removed. Improve surface and subsurface drainage by diverting all surface and groundwater away from the soil absorption field.
