Confirm the Reason for Replacement
Rule out an outlet blockage, faulty pump or localized distribution issue first. When the receiving soil no longer functions adequately, recurring pump-outs may offer only short relief. Findings should explain why replacement is recommended and what can remain.
Plan the Disposal Area
A suitable footprint needs the required separation from structures, wells, boundaries and other features. Evaluate usable soil and wet-season groundwater. Landscaping, paving and additions can limit both available space and construction access.
Field-Only Versus Complete Replacement
Retaining a suitable tank while replacing a field is different from replacing both. Miami-Dade prohibits conventional Type 1 systems for new and complete replacement projects. Determine the proper repair or replacement pathway for the work actually proposed.
Replacement and Aeration Are Different
A replacement creates a new disposal area. Aeration or an advanced aerobic conversion changes a restoration or treatment approach. It must be suitable and approved for the system. The $11,000 starting figure does not mean aeration can save every failed field.
Protect the New Field
Keep vehicles and paving off the designated area. Maintain the tank and outlet filter. Spread out high-water-use activities and fix leaks. Keep the approved layout so later landscaping or construction does not damage the new system.
