Water and the sink line in Summerville

Summerville CPW has received all of its water from the Santee Cooper Regional Water System since October 1994 — a surface-water treatment plant on Lake Moultrie, expanded to 40 million gallons per day in 2018 and delivered through a transmission main about 20 miles long — with three emergency standby wells and an emergency connection to Charleston Water System as backup (https://www.summervillecpw.com/history; https://www.summervillecpw.com/water). Summerville CPW has completed a system-wide lead service-line inventory and states it can certify that no lead service lines are present in its distribution system (https://www.summervillecpw.com/serviceinfo).

Soil, drainage and the base

Summerville sits inland on the higher, well-drained sandy ridges of the Atlantic Coast Flatwoods — the reason 19th-century Lowcountry planters built summer homes here to escape the mosquito-heavy rice lowlands — and the USDA Dorchester County soil survey maps nearly level sandy upland ridge soils dissected by lower, wetter flats (https://www.govinfo.gov/content/pkg/CZIC-s599-s58-e64-1990/html/CZIC-s599-s58-e64-1990.htm).

What the local stock means here

Summerville sits in Dorchester County, served by Summerville Commissioners of Public Works (Summerville CPW). 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

Summerville CPW is a self-supporting Commissioners-of-Public-Works utility that runs entirely on water and sewer fees and receives no tax revenue, serving over 27,887 water customers about 9.25 million gallons a day (https://www.summervillecpw.com/history).
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).
