New Septic Systems for Dunwoody Properties

Whether you are building a new home in Dunwoody or replacing a system that has reached the end of its life, septic installation is a project that starts with the soil. The right system depends on your lot, your soil and the size of your household.

Request a call and a local septic company that installs systems in Dunwoody and Sandy Springs, Doraville, Chamblee will explain the process from site evaluation to final inspection.

The installation process step by step

It starts with testing the soil to see how well it absorbs water. A designer or engineer then sizes the tank and dispersal area for the number of bedrooms. After the permit is approved, the crew excavates, sets the tank, installs the pipes and field, and schedules an inspection before backfilling.

Choosing the right system

The best system is the one your soil and lot can support. Good, deep soil often allows a conventional system. Clay, high groundwater or shallow bedrock may call for a mound, pressure distribution or an aerobic unit. Each has different costs and maintenance needs, so ask your installer to explain them.

Permits and approvals

New and replacement systems almost always need a permit. Expect a soil evaluation, a design that meets local code, plan review and at least one inspection during installation. the DeKalb County health department or your state agency sets the requirements, and many installers handle the application for you.

Understanding installation quotes

A complete quote should cover design, permits, excavation, the tank, the dispersal system, inspections and site restoration. Ask what is excluded, such as tree removal, electrical work for pumps or driveway repair. Compare quotes for the same system type.

Protecting your investment

A new system can last decades with basic care. Know where every part is, avoid planting trees near the field, send roof water away from it, and keep grease, wipes and chemicals out of the drains. Schedule the first inspection and pumping so you have a baseline for later visits.

Questions for a septic installer

Ask who will do the soil test and design, whether they pull the permit, and which system types they recommend for your lot and why. Ask how long the project will take, what warranty they give, and whether the quote includes restoring the yard. Ask for references from recent jobs near Dunwoody.
