You bought a new build in Foxbank Plantation. The house is solid. The neighborhood is growing. The 67-acre lake is a selling point.
But the water flowing through your brand-new pipes comes from the same source as every other CPW customer in the Lowcountry. Here's the cited data for Foxbank.
Your Water Source
Foxbank Plantation sits in Berkeley County, within the Moncks Corner area. Your water is supplied by Summerville Commissioners of Public Works (CPW), sourcing from Lake Moultrie via the Santee Cooper Regional Water System.
This is the same utility that serves Nexton, Cane Bay, Carnes Crossroads, and Summerville proper. The chemistry is identical.
7.2 Grains Per Gallon
CPW water measures about 7.2 gpg, moderately hard per the USGS scale. Charleston Water System, which serves the peninsula and parts of the metro, runs about 3.4 gpg.
If you PCS'd from a base in a softer-water region, that jump explains the showerhead crust, the dishwasher spots, and the soap that doesn't rinse like it used to.
What 7.2 gpg Means for Your DR Horton or Dream Finders Build
Your home is new. Your pipes are new. Your water heater is new. But 7.2 gpg hard water starts depositing scale on those new components from day one.
- **Showerheads** scale inside 30-60 days
- **Dishwasher** leaves film on glasses
- **Water heater element** begins accumulating calcium scale
- **Soap** leaves residue on skin and hair
- **Laundry** comes out stiffer
Your new home won't protect you from old water.
Foxbank Community Context
Foxbank Plantation covers about 800 acres with 141 acres of wetlands and a 67-acre signature lake. Builders include DR Horton, Dream Finders Homes, and Crescent Homes. The price range runs roughly $200,000 to $400,000, which makes it accessible for military families on VA loans.
The community is about 25 miles from downtown Charleston and sits within Berkeley County School District. It's a growing neighborhood with new builds going up consistently.
Chlorine Disinfection
CPW uses chlorine. If you notice a pool smell from the tap, especially in the morning, that's normal at regulated levels. A carbon filter at the kitchen tap addresses the taste.
If you've been stationed somewhere that used chloramine (which many larger metro water systems do), the chemistry here is different. Chlorine is simpler to filter but produces different disinfection byproducts than chloramine.
EWG Flags: 11 Contaminants Above Health Guidelines
The EWG Tap Water Database flagged 11 contaminants above EWG health guidelines for Summerville CPW (testing 2014-2023). The most notable include disinfection byproducts (TTHMs at 168x EWG guideline, HAA9 at 368x) and PFAS compounds (PFUnA at 1,183x guideline).
All readings are within EPA legal limits. EWG applies stricter benchmarks. The detailed breakdown is in our Nexton water report and Summerville PFAS report. Both cite the same CPW data because the same utility serves all these communities.
Zero Lead Service Lines
CPW completed its lead service line inventory and found zero lead pipes in the system. Your Foxbank service line is not lead per the published data. This is different from Charleston Water System, which identified about 6,000 lead service lines concentrated in peninsular Charleston and the North Charleston Neck corridor.
The March 2026 Boil-Water Advisory
On March 17-18, 2026, a contractor punctured the Santee Cooper main line at the Lake Moultrie Regional Water Plant. About 70,000 CPW customers were placed under a boil-water advisory. Foxbank Plantation was in the affected zone. The advisory was lifted 24 hours after repair.
CPW activated its three emergency wells (combined capacity of about 5 million gallons per day) as supplemental supply during the repair.
Foxbank's New-Build Reality
The builders serving Foxbank (DR Horton, Dream Finders Homes, Crescent Homes) use modern plumbing materials. PEX or copper supply lines. No galvanized steel, no lead solder. Your internal plumbing is clean.
But new plumbing doesn't change the incoming water chemistry. Your brand-new PEX line delivers the same 7.2 gpg water that a 20-year-old copper line in Summerville proper delivers. The pipes are new. The water is the same.
Most newer builds in Foxbank route the main water shutoff through the garage, which makes whole-home conditioning installation straightforward. A typical install takes about 4 hours from the shutoff valve to the final test.
For Military Families
We work with active-duty and spouse families who've PCS'd into the Foxbank area. If the service member is deployed, we work directly with the at-home partner for everything from the free water test to the install. The process is straightforward: test, quote, schedule, install. Paper trail clean. Schedule flexible.
If you're renting off-base housing, check with your landlord about install approval. If you're buying on a VA loan, the system is a home improvement that you own.
FAQ: Foxbank Water
Is Foxbank water different from Cane Bay water?
No. Both are on Summerville CPW. Same source, same hardness, same disinfection. The only variable is your home's internal plumbing and distance from the distribution main.
I'm on well water near Foxbank. Is that different?
Yes. Well water in Berkeley County can have a different set of issues: iron, hydrogen sulfide, manganese, and variable hardness. The free water test covers well water with a full appropriate panel.
What about the 141 acres of wetlands?
The wetlands are part of Foxbank's ecosystem design. They don't directly affect your tap water, which comes from the CPW municipal supply, not from the local water table. But if you have a well (some properties near Foxbank's perimeter do), the local water table and its interaction with the wetlands can influence well water chemistry.
How does Foxbank's price range ($200K-$400K) affect financing?
Our standard whole-home install is around $7,999. Financing is available through a partner lender, subject to credit approval. We walk through the exact APR, term, and total of payments in person before you sign anything. See the financing page on our website for the full Truth in Lending disclosure.
