Water and the sink line in Mount Pleasant

Mount Pleasant Waterworks (MPW) is the town's independent public-works commission, and it buys its treated water wholesale from Charleston Water System, so the supply originates from the Bushy Park Reservoir / Edisto River surface-water system (https://www.charlestonwater.com/139/What-We-Do). MPW's own August water-quality report lists a hardness of 44 ppm, alkalinity of 72 ppm and pH of 8.6, and the utility runs its own lab that collects over 1,000 samples and performs more than 14,500 tests a year (https://mountpleasantwaterworks.com/; https://mountpleasantwaterworks.com/your_water/water/water_quality_reports.php).

Soil, drainage and the base

Most Mount Pleasant lots are underlain by the Charleston series loamy fine sand over fine sandy loam — friable, low shrink-swell, non-expansive and very strongly acid — on flats near Shem Creek and the Wando River, with rapid-draining hydrologic group A profiles that sit close to tidal water tables (https://soilseries.sc.egov.usda.gov/OSD_Docs/C/CHARLESTON.html).

What the local stock means here

Mount Pleasant sits in Charleston County, served by Mount Pleasant Waterworks. Charleston is a humid-subtropical Atlantic port where onshore sea breezes off the harbor and tidal rivers carry airborne chlorides inland, relative humidity runs high year-round (mornings commonly 83-86%), and summer dew points sit near 73 F, so outdoor surfaces are wet almost every night from May through September (https://www.northcharleston.org/visitors/attractions_points_of_interest/weather_and_climate.php; https://www.weather.gov/chs/). Salt deposition is severe within roughly a mile of tidal water and high out to about five miles, with ASTM G92 chloride-deposition rates reported as high as 10x inland baselines, and the National Hurricane Center's June 1 to November 30 Atlantic hurricane season brings wind-driven rain plus salt-laden storm surge across the whole metro (https://sccoastalpools.com/blog/salt-air-corrosion-pool-equipment-charleston-coast/; https://www.nhc.noaa.gov/climo/). On an outdoor kitchen, salt plus constant moisture attacks the fasteners first — standard 304 stainless and uncoated metal pit, tea-stain and seize within a few seasons — so marine-grade 316 stainless hardware, powder-coated aluminum or masonry cabinet shells instead of wood framing, and sealed non-ferrous countertops (granite, quartzite or sintered stone) are the spec that holds up here (https://charlestonoutdoorliving.com/kitchen-corrosion/). Heat cycling compounds it: metal expands and contracts, coatings micro-crack, and chlorides wick into the joints, where corroded connections become the usual point of failure (https://charlestonoutdoorliving.com/kitchen-corrosion/).

What to check in this town

MPW is a public-works commission governed by an elected Board of Commissioners — not a city department — with its operations center at 1619 Rifle Range Road, Mount Pleasant, SC 29464 (https://mountpleasantwaterworks.com/).
Permits: The City of Charleston issues residential structural (building), plumbing, electrical and fuel-gas permits through its Department of Development and Construction Services — Building Inspections Division, i.e. the Permit Center at 2 George Street, Charleston, SC 29401, phone 843-577-5550, with applications accepted in person and via the city's online Customer Self Service portal (https://www.charleston-sc.gov/856/Permit-Center). Properties in unincorporated Charleston County permit instead with Charleston County Building Inspection Services, and Mount Pleasant, Summerville, North Charleston and Goose Creek each operate their own building department — confirm which jurisdiction governs the parcel before filing.
Call 811 before anyone breaks ground for the island footings, the gas run or a water line — free locate, several days' notice.
South Carolina's Contractors' Licensing Board interpreted on July 21, 2016 that anyone performing natural-gas piping must hold a South Carolina Mechanical Contractors license with a Plumbing (PB) classification, which covers running a natural-gas line to a residential grill; LP/propane gas work instead requires an SC LP Gas Installer license issued by the State Fire Marshal's Office (https://llr.sc.gov/clb/updates.aspx). Separately, the statewide-adopted South Carolina Fuel Gas Code requires a permit from the local code official before fuel-gas piping is installed, altered or replaced, so a grill gas line needs its own fuel-gas permit and inspection apart from the building permit (https://up.codes/viewer/south_carolina/ifgc-2021/chapter/1/scope-and-administration).
Three approval layers can apply before an outdoor kitchen is built in the Charleston area. (1) Private HOA covenants and architectural-review-committee rules: most Charleston-area planned communities require design sign-off before a permanent outdoor structure is built, so read the covenants first. (2) Historic-district review: in the City of Charleston's Old and Historic District and other local districts, any exterior work visible from the public right-of-way needs a Certificate of Appropriateness from the Board of Architectural Review before a building permit will issue (https://charleston-sc.gov/BAR). (3) Flood-zone compliance: in the Special Flood Hazard Area the City of Charleston requires new residential construction to be designed 2 feet above Base Flood Elevation and documented with a FEMA Elevation Certificate, and marsh-adjacent lots may also trigger SC OCRM critical-area review (https://www.charleston-sc.gov/1944/Floodplain-Management).
