How do you get a new septic system installed near Madison, GA?
Outside Madison's sewer, a new home needs a septic system permitted by Morgan County Environmental Health. The office reviews the site plan, issues the construction permit and inspects the finished system; the residential inspection fee is $350, or $400 for five bedrooms. We lay out, permit and install the system.↗↗

The Madison story
Building in the country around Madison
Madison sits on a ridge that divides the county's drainage, and once you leave the city limits the sewer ends. The county's plan says housing in unincorporated Morgan needs wells and septic systems, and it cites 0.6 acre as the least land a septic system needs.↗↗
The practical sequence is well, then septic, then house. Once the well is placed, the tank must sit 50 feet away and the field 100 feet, and the remaining ground decides how big a home the lot can carry.↗↗
More about Madison
New subdivisions and commercial buildings
Developers laying out rural lots around Madison go through a separate county review before individual permits: the subdivision plat is reviewed, then each lot. Businesses outside town are permitted by expected daily flow, with inspection fees that climb with each tier.↗
Lots on the Morgan side of Lake Oconee add one more reviewer. Georgia Power protects a 25-foot vegetative buffer along its shoreline and does not allow clearing or regrading of its project land without written approval, so tank and field locations, and the path the equipment takes to reach them, have to be planned from the uphill side.↗

Soil & terrain
What the ground allows
Around Madison the soils are mostly well drained, with Cecil sandy loam mapped at one point near the city and severely eroded Lloyd clay loam at another. Where erosion has stripped the topsoil, the field goes into denser subsoil and usually needs more trench length.↗
Tank size follows bedroom count, not soil: 1,000 gallons through four bedrooms, 250 more for each additional bedroom, and half again if the kitchen has a garbage disposal.↗
