Mound Systems
Raised drain fields engineered for sites where groundwater sits too high for conventional trenches.
How mound systems work →Coastal soils and high water tables rule out conventional systems on many Ravenel properties. We connect you with independent local specialists who design and install the engineered systems these sites actually require — permitted, inspected, and built for the ground you own.
Tell us about your property and we will match you with an independent local pro who specializes in the system type your site requires.
Raised drain fields engineered for sites where groundwater sits too high for conventional trenches.
How mound systems work →Mechanical treatment for tight lots and poor soils, producing cleaner effluent before dispersal.
How ATUs work →Pressurized shallow dispersal for thin soils over restrictive layers — common near the coast.
How drip systems work →The soil workup that determines which system your property can legally support — required first.
The evaluation process →Failing fields, backups, and surfacing effluent diagnosed by pros who understand coastal soils.
Request an evaluation →Tank locate, open-and-pump evaluation, and a written report before you close on rural property.
Schedule an inspection →Call (803) 000-0000 or send the quote form. New build, existing home, or land you are evaluating — it takes about a minute.

Ravenel sits in the rural southern end of Charleston County, between the ACE Basin's protected wetlands and the growing edges of Hollywood and Johns Island. It is large-lot country — farmland, equestrian properties, and wooded acreage — and most of it has never had public sewer. With the town's recent limits on larger subdivisions, new homes here go on septic as a matter of course; local listings now routinely note that septic is required.
The ground is the story. Coastal soils around Ravenel pair sandy surface layers with restrictive clay underneath and a seasonal water table that can sit uncomfortably close to the surface. South Carolina's onsite wastewater rules (Regulation 61-56, administered by SCDES) require the system design to fit the site: where a conventional gravity drain field cannot meet the separation distances, the permitted answer is an engineered system — a mound, an aerobic treatment unit, or drip dispersal — sized from a soil evaluation done on your specific lot.
Properties near wetlands and waterways face an additional layer of review, and that review is only getting more attention statewide. That is why the soil evaluation comes first and the system design follows it — never the other way around. When you request a quote through Ravenel Septic Pros, tell us the property's location, whether it is a new build or an existing system, and anything you know about wet areas or past drainage issues. The specialist we connect you with will take it from there.
Our network of independent specialists covers Ravenel and the surrounding Charleston County communities.
Much of the area sits on coastal soils with a high seasonal water table. State rules require the system design to match the site's soil and groundwater conditions, which a soil evaluation determines. Where a conventional drain field won't work, engineered options like mound systems or aerobic treatment units are used instead.
A mound system is a drain field built up above the natural ground surface in layers of sand and gravel. It is used where the water table is too high or the soil too shallow for a conventional in-ground field, because it creates the separation distance the treatment process needs.
Yes. SCDES must approve the site and issue a Permit to Construct before a system can be installed, and the county building permit depends on it. The independent pros in our network handle the application as part of the job.
