Sewer, Soils and Shoreline: What Is Different in Myrtle Grove
Myrtle Grove is an unincorporated community: the Census Bureau counts it as a census designated place, wholly in New Hanover County. County zoning, building permit and floodplain rules apply. The Cape Fear Public Utility Authority (CFPUA) says its service is not yet available in some areas, so check with CFPUA about sewer for your lot.
In USDA soil survey data for the Myrtle Grove area, Leon sand covers the most ground, then Murville fine sand, Lynn Haven fine sand, Wakulla sand and Kureb sand. USDA's series descriptions call Leon poorly and very poorly drained, its water table at depths of 6 to 18 inches for 1 to 4 months during most years. Lynn Haven is poorly or very poorly drained, and Murville very poorly drained, its water table at or near the surface most of the time except in summer or where artificially drained. Wakulla is somewhat excessively drained, Kureb excessively drained. NC State Extension says a soil survey helps with planning but cannot replace an on-site evaluation.
State rules require 12 inches or more of naturally occurring soil below a trench bottom in natural ground, down to any limiting condition, plus pressure dispersal where a soil wetness condition lies within 18 inches and more than six of those inches are sand or loamy sand. Tidal water is one cause of that condition. Advanced pretreatment can allow smaller separations, but 12 inches to tidal water must always remain.
Myrtle Grove sits in a Coastal Area Management Act county, and the state classes nearby stretches of the Intracoastal Waterway and Masonboro Sound as SA (market shellfishing) and Outstanding Resource Waters, and Everett Creek as SA. State rules generally keep a septic system 100 feet from SA waters and 50 feet from marshes and other tidal waters, measured from the mean high-water mark.
The New Hanover County Permit Path for a Myrtle Grove Lot
Unless you use a private permit route, New Hanover County Environmental Health's On-Site Water Protection section (230 Government Center Drive, Wilmington; 910-798-6667) issues Myrtle Grove septic permits. Its pages and state law give this order:
- Application. File a Septic System Improvement application in the county's COAST portal, with a site plan, survey or plat showing structures and driveways, plus, where applicable, nearby wells, sewer connections, marshes and CAMA setbacks.
- Lot preparation. Mark the corners and lines with stakes or flags and bush-hog heavy undergrowth.
- Evaluation. The county's Environmental Health Specialist judges whether site and soil meet minimum requirements; you may instead retain a licensed soil scientist.
- Improvement Permit (IP). Issued only for a site classified suitable, it lets the site be used.
- Construction Authorization (CA). Following a field investigation, the CA determines the system type; it may accompany the IP and comes before building permits.
- Installation. With a few exceptions, state law says the installer must hold contractor certification matching the system.
- Inspection and Operation Permit (OP). The county inspects before cover, or an Authorized On-Site Wastewater Evaluator you hire does. After a county inspection confirms proper installation, the county issues the OP for use and occupancy.
Matching the System Design to a Myrtle Grove Site
The EPA lists household size, soil type, slope, lot size and nearness to sensitive water bodies among design factors, and on the county route your CA settles the type.
We install whichever design your permit requires, such as:
- Conventional. Effluent flows from the tank into a trench or bed. Its best sites, per NC State Extension, slope gently, with deep water tables under thick, permeable soil.
- Conventional with a lift station. A lift station pumps water to drain lines set too far from the tank.
- Chamber. The drain field is built from connected chambers, a type the EPA calls well suited where groundwater tables are high; state separation rules still apply.
- Low-pressure pipe (LPP). Light pressure, three to six feet of head, pushes effluent through small pipes across the entire field.
- Drip distribution. Per the EPA, drip lines lie at a depth of 6 to 12 inches, and a large dose tank delivers timed doses.

Had an unknown emergency with our septic tank during Hurricane Debby. Tracy quickly confirmed it was an emergency, had the crew out within 1.5 hours. When they got there, they were efficient, informative, professional, & honest. Thank you Tracy, Ej & Josh. I highly recommend.

Coastal Septic Solutions was contracted to fix an issue caused by another company. They were super professional and polite and extremely helpful anytime I needed to call to find out the process and when I would expect or could expect the repairs to take place. The day they arrived everybody was in and out very quickly and took into account that I work from home and managed to keep the noise to a minimum and most of the time I forgot they were even outside my house. Definitely recommend their services.

I contacted Coastal about coming out to take a look at my septic tank lines. I had a issue with roots growing into the lines causing them not to drain properly. When I contacted them they were very understanding and came right out to look at the issues. They corrected the problem and even put out grass seed where they had to dig up the lines!

Our septic tank wasn't draining properly and Jonathan came and assessed the situation quickly that we needed a new drain field. He obtained the necessary permit, all the materials needed were delivered the next day, and he and his crew came the next day. They laid a 55ft drain field, cleaned up the yard and were done by mid afternoon. He and his crew work well together and do a beautiful job!!! They are all very personable and we highly recommend Coastal Septic Solutions for any septic problems. Charles and Marysusan Rice.

Sam and Josh showed up on time and were very polite and knowledgeable with my overload of questions about how the system functions and ways to better maintain our system. They found our tank, inspected the system, cleaned the system out, and cleaned up the area with ease and speed. I highly recommend these guys for your next service. I was able to learn alot also. Thanks and be safe.
The Stages of a Myrtle Grove Septic Installation
- Sewer answer and permits. Check sewer with CFPUA, and on the county route a qualifying lot gets its IP and CA.
- Free estimate. Email the CA or attach it to this page's form, and we estimate the system it names.
- Site clearing. Trees or brush standing where the system goes may need removing.
- Tank and drain field. We install both as your permit specifies.
- Inspection. On the county route, backfill follows the county's or your evaluator's inspection.
- Cover. Settled cover must be at least six inches deep, runoff is directed away, and grass keeps the soil from eroding.
- Going into use. On the county route, the OP or a hired evaluator's written verification clears the system for use.
What Can Stretch the Timeline in Myrtle Grove
Outside steps that can change your schedule:
- Sewer letter. CFPUA replies to a completed Request for Information form within five business days; that letter does not approve a connection.
- Flood zones. In a Special Flood Hazard Area, development waits for a county Floodplain Development Permit describing all covered development, septic included.
- CAMA permits. Within 75 feet of an estuarine shoreline or 575 feet of an Outstanding Resource Water shoreline, development is probably in a CAMA Area of Environmental Concern. Ask the county's CAMA permit officer whether your septic work needs a permit; minor permits are decided within 25 days unless extended 25 more.
When You Are Building, Replacing a System or Running a Business
New construction. On the county route, building permits wait for the CA. State rules generally set a home's minimum tank at 1,000 gallons for four or fewer bedrooms and 1,250 for five, doubled if a grinder or sewage lift pump precedes the tank.
Replacement systems. Barring a private option, a failing system needs a health department permit before repair; New Hanover posts a Homeowner Interview Form for its evaluation. Most housing sites permitted since the early 1980s need a repair area, where a more sophisticated system may be required.
Businesses. Their tanks are generally sized from design daily flow rather than bedrooms.
Coastal Septic Solutions installs septic systems for residential and commercial properties.
Septic Care Once Your System Is Running
- For a new house, request the installer's as-built diagram; NC State Extension notes such drawings can carry details absent from the permit.
- The EPA advises an inspection at least every three years and says household tanks are usually pumped every three to five years; see our septic tank pumping service.
- Have systems with pumps, float switches or other mechanical parts inspected about once a year.
- Never park or drive on the drain field, or pave it without approval.
- Keep native grasses or ground covers on the field, and plant trees well beyond root reach.

Myrtle Grove Septic Questions for Lot Buyers and Homeowners
Before buying a lot in Myrtle Grove, what should I find out?
Ask CFPUA Development Services about sewer for the lot; its existing service map does not address vacant lots. If the lot will rely on septic, NC State Extension advises an Improvement Permit before you buy, and a county plat certificate says plat approval guarantees neither septic approval nor CFPUA service.
Can I hire my own experts instead of relying on the county's evaluation?
You may retain a licensed soil scientist to evaluate soil and site, and state law allows two private permit routes, an Engineered Option Permit or the Authorized On-Site Wastewater Evaluator option, with county-posted forms for both. The owner then submits a Notice of Intent to Construct to the local health department before work begins.
How long can I hold a septic permit before building?
Under state law, an Improvement Permit issued with a plat does not expire; one issued with a site plan lasts five years, and changing the plat, site plan or intended use can lead to revocation. The CA's validity runs with its IP.
What if CFPUA sends me a letter about connecting to sewer?
Under CFPUA's posted connection deferral policy, an owner has 60 days after a mandatory connection letter to request a deferral, which, if granted, lasts up to three years and may be reapplied for once. It is void if the septic system fails or needs a repair the County Health Department mandates, and the owner must then connect.
Can I add a pool, an addition or an accessory dwelling later?
NC State Extension advises clearing plans with the county health department first, so the system and repair area stay undisturbed and big enough. If a project will not increase design daily flow or wastewater strength and will meet local and state setbacks, state law allows an existing system inspection exemption affidavit (Appendix H) with the permit application. A detached accessory dwelling on a septic-served property must meet county Environmental Health well and septic standards.
