What changes in Hilliard

Pine flatwoods hold a shallow table that comes up in the wet months, and a Hilliard replacement is designed to the seasonal high rather than to a dry-season visit: the tank set and backfilled against flotation, the field sized and elevated to keep the required separation, and a mound where the natural ground cannot provide it. The county health department in Nassau permits and inspects it.

The wellhead's distance from the new field is measured and the ground graded so surface water runs away from both.

How the job runs

How a tank is replaced

The failed tank is pumped and inspected so the replacement is quoted from what is seen. The permit is filed with the county environmental health office, with the new tank sized to the bedroom count. The drain field is inspected honestly before the new tank is connected to it. The new tank, precast concrete or polyethylene depending on access and groundwater, is set level with risers to grade and inlet and outlet connected. The old tank is pumped, crushed and filled, or removed. The county inspects before backfill and the record is closed. Financing through Hearth is available.

Straight answers

Septic Tank Replacement questions from Hilliard

Why does the design depend on the season?

Because the flatwoods table rises every autumn, and a field designed in May fails in September.

Will the new system need a mound?

Where the separation does not exist in the natural ground, yes.
