Alternative Septic Systems in Onslow County, NC

When a conventional system isn't an option

A conventional septic system relies on gravity and a good depth of suitable soil to absorb and treat wastewater. Plenty of properties in Onslow County and coastal Eastern North Carolina don't have that. When a lot doesn't qualify for a conventional system, an alternative system is usually how the property can still be served.

Common reasons a lot needs an alternative system include:

• Poor soils — tight clays or soils that don't absorb water well
• High water table — groundwater close to the surface, common in low-lying coastal areas
• Limited space — small or irregular lots without room for a conventional field and the required setbacks
• Elevation — a drainfield area that sits uphill or far from the house

Your options

The approved permit decides the system

You don't pick an alternative system off a menu. The county health department evaluates the property and issues a permit and site plan that specify the system type, its size and where it goes. We review that approved plan with you, explain what it calls for in plain language, and install the system exactly as approved.

Basic upkeep these systems need

Alternative systems have more moving parts than a gravity system, so a little attention goes a long way:

• Never ignore a control panel alarm — it usually means a pump or float problem
• Keep the tank pumped on a regular schedule so solids don't reach the pump or lines
• Keep vehicles, heavy equipment and structures off the field and tubing
• Spread out laundry and heavy water use rather than doing it all at once
• Follow any maintenance or service requirements listed on your permit
