In many areas centralized sewer service may become available, providing homeowners with an environmentally responsible option for wastewater treatment. Testing is also under way to determine whether new septic systems that remove nitrogen are appropriate for Florida. Meanwhile, homeowners with septic systems in their yards are responsible for properly maintaining the systems to reduce health and pollution hazards. A septic tank should be opened and inspected every two to three years by a septic tank contractor, who will determine whether it needs to be pumped out. Do not plant trees or shrubbery over a septic tank or drain field.
Roots can choke the drain field, reduce the tank's capacity or block the tank's inlet or outlet.
Do not place grease or fibrous products, such as fruit peelings, in the garbage disposal. Replacement is the only remedy for a clogged drain field. It cannot be repaired by cleaning or the infusion of enzymes. Do not add yeast or bacteria to your septic tank. Avoid overtaxing your septic system by spacing laundry loads throughout the week rather than several loads on just one or two days.
