What is different about installation in Coral Gables
New septic systems in Coral Gables are almost always replacements or rebuilds on established lots; the city has 7,934 septic parcels in the County's 2020 count and a median home built in 1969. A new system needs DERM approval and an advanced treatment unit, and none is allowed where a public sewer abuts the property.
On a knock-down rebuild, plan the system early with the architect. The drain field and its reserved area, the 100-foot setback from canals and the 36-inch separation from the wet-season water table all shape where the house, pool and driveway can go.
Coral Gables lots often carry protected trees, coral rock walls and pools, and the County requires the whole system to stay 100 feet from surface water. With a median home value of about $1.09 million, owners usually also want the finished system to disappear into the landscape: low lids at grade and a field planned around the garden.
