Septic Service in Thonotosassa, FL

Thonotosassa is a rural unincorporated community in northeastern Hillsborough County, named for Lake Thonotosassa, one of the larger lakes in the county. Many homes here are on septic systems and private wells, including homes near the lake and its surrounding wetlands. Near surface water, a working septic system protects both your household and the lake.

Septic systems near lakes and wetlands

Florida rules generally require septic systems to be set back from surface waters, wetlands, and wells. Older lakefront homes may have systems installed under older standards. If a system near the water needs repair or replacement, the new design may have to meet current setbacks and water table requirements, which can change where and how it's built. Ask the septic company what options fit your lot.

Why lakefront drainfields struggle

High water tables near the lake, especially in the summer rainy season.
Low ground that holds water after storms.
Older, smaller systems serving homes that have been expanded.

Signs of trouble include soggy ground or odors over the drainfield and slow drains after rain. See drainfield problems and repair.

Good habits for homes near water

Pump the tank on a regular schedule; see septic tank pumping.
Avoid fertilizing over or near the drainfield.
Keep grease, chemicals, and medications out of drains.
Direct gutters and runoff away from the drainfield.

Wells and water testing

Many Thonotosassa homes rely on private wells. After a septic backup, flood, or any change in water quality, have the well tested. The Florida Department of Health has information on private well testing.

Flood zones

Some properties near the lake and creeks are in mapped flood zones. Check yours at the FEMA Flood Map Service Center, and after flooding, have the septic system checked before returning to normal use.

Docks, seawalls, and access

On lakefront lots, the septic system is often between the house and the water or squeezed beside the home. Before building a dock path, a boathouse, a seawall, or a new patio toward the lake, have the system located so heavy equipment stays off the tank and drainfield. Tell the septic company about any gates or narrow side yards so it can plan how to reach the tank with a hose.

Frequently asked questions

Do septic systems near Lake Thonotosassa have special rules?

Florida rules generally set minimum distances between septic systems and surface waters, wetlands, and wells. Older systems may predate current rules, which matters when they're repaired or replaced.

Why does my lakefront drainfield stay wet?

A high water table and low ground near the lake can leave the drainfield little room to absorb wastewater, especially in the rainy season. Have it checked if it's soggy in dry weather.

Should I fertilize over my drainfield?

It's best to avoid it, especially near a lake. Keep fertilizer and chemicals off and near the drainfield.
