Installing a water line means trenching from a meter or well to the house, bedding pipe of at least 3/4 inch, and backfilling. Georgia code keeps the line out of septic tanks and drain fields and 5 feet from a sewer unless sleeved or raised. Public mains need 24 inches of cover and 10 feet from sewers.

Plain definitions
The whole story
Around the two lakes a water line can start in three very different places. In town it starts at a utility meter: Baldwin County's water ordinance has the county install the service line to the road right-of-way and set the meter, typically within 3 feet of it, and everything from there to the house is the owner's. Outside the towns it often starts at a private well. Morgan County's service delivery strategy names Rutledge, Bostwick, Buckhead and Madison as the only water providers, and says all other areas rely on in-ground wells and pump houses.
Lake homes add distance. A house set well back from the road on a deep lot, or a cabin down a long gravel drive, can need hundreds of feet of service line, and that line has to dodge the septic tank, the drain field and its repair area. Georgia's septic rule keeps drain fields 10 feet from water supply lines, and the plumbing code keeps water pipe out from over or under any part of a septic system. On a tight lake lot those two rules decide the route before anything else does.
Older public lines are part of the picture too. Baldwin County's 2023 comprehensive plan says every galvanized water line in the Coopers area needs replacement, and the same plan flags water pressure southeast of Lake Sinclair as needing to rise with development. When a utility replaces its main, owners often find their own aging service line is the next thing to go.
How the job runs
We locate the meter or well head, the entry point at the house, and the septic tank, drain field and sewer line, then lay out a route that respects the separations in the code.
Georgia State Minimum Standard Plumbing Code 2018, Chapter 6 Water Supply and Distribution (UpCodes)
Any trench dug by machine needs a locate request first. Inside the marked tolerance zone, the facility width plus 18 inches each side, the digging switches to hand or vacuum methods.
Georgia 811 — Georgia Utility Facility Protection Act (O.C.G.A. 25-9) summary
On a utility system the tap and meter are bought from the utility; EPWSA, for example, lists $1,330 for a 3/4-inch water tap plus a separate capacity charge. On a well system the line ties into the pressure tank or pump house.
EPWSA Schedule of Rates, Fees, and Penalties (effective 5.16.25, corrected)
The trench is cut to the planned depth. Where the Piedmont throws up stone, rock is removed for at least 6 inches below the pipe, the same clearance EPD sets for public mains.
Georgia EPD — Minimum Standards for Public Water Systems (revised March 2021)
Pipe goes on continuous, uniform bedding. On mains, bends, tees and valves get thrust blocking or restrained joints, and non-metallic pipe gets detection tape so it can be found later.
Georgia EPD — Minimum Standards for Public Water Systems (revised March 2021)
The line is pressurized and checked for leaks before it is buried. Backfill is tamped in layers around and above the pipe so it is supported and protected.
Georgia EPD — Minimum Standards for Public Water Systems (revised March 2021)
New lines are flushed to clear trench debris, the surface is graded, and bare soil is seeded or mulched so the trench line does not wash.

OPTION 01
When it fits: New service lines, new distribution lines on open ground, and any run that has to change depth or direction often.
OPTION 02
When it fits: Short crossings under a driveway, road or mature landscaping where digging would cost more to repair than to bore.
OPTION 03
When it fits: The old line follows a clear, legal route and simply failed from age.

Homes & businesses
Residential
Most residential work is a service line from a meter or well to the house, or a branch to a barn, shop, guest house or boathouse. We plan these routes around the septic system first, since that is the code constraint most often missed.
Commercial
Waterline distribution systems and mains serve more than one connection and follow Georgia EPD's Minimum Standards when they are part of a public system: 2-inch minimum mains, 6-inch where hydrants attach, 24 inches of cover and 10 feet from sewers. We install to the engineer's plan and the utility's specifications.

(678) 863-5620National cost guides put main water line installation at $75 to $225 per linear foot, with most owners paying $100 to $200 per foot, and whole jobs from about $1,500 to $12,000 (Fixr, 2025). Length is the biggest driver. Any utility tap or meter fee is separate; EPWSA's 3/4-inch water tap is $1,330 before its capacity charge.

For public water mains Georgia EPD requires at least 24 inches of cover over the top of the pipe to protect it from freezing. Private service lines follow the plumbing code and local practice, which generally means burying them below frost and deep enough to protect them from traffic. Lines under driveways need more cover or a sleeve.

Not over, under or through it. Georgia's plumbing code bars potable water service pipe in, under or above septic tanks, drain fields and seepage pits, and the septic rule keeps absorption fields 10 feet from water supply lines. If a crossing cannot be avoided, the line goes at least 12 inches above the gravel layer inside a larger sleeve pipe.

Only when the sewer is made of the pressure-rated materials listed in the plumbing code's Table 702.2. Otherwise the two pipes need 5 feet of undisturbed or compacted earth between them, or the water line must be at least 12 inches above the top of the sewer wherever they are within 5 feet. Public mains need 10 feet.

Usually the property owner. Under Baldwin County's water ordinance, for example, the county installs the service line to the road right-of-way and sets the meter near it; the pipe from the meter to the house belongs to the owner. Check your own utility's rules, since a few draw the line at the property line instead.

If the line comes from a new private well, the well itself needs a permit from county Environmental Health before drilling, and in Greene County a lot on a private well must be at least 1.5 acres for a septic system, not counting land within 75 feet of Lake Oconee's high-water line. The service line from the well follows the plumbing code.
Source: Greene County Board of Health — Lot Size Ordinance (effective Sept 7, 2018)
Georgia's plumbing code sets 3/4 inch as the minimum water service size and says the line must be sized to deliver the flow and pressure the building needs. Long runs, big houses with many fixtures, and lines that also feed irrigation often justify 1-inch pipe. Utilities price taps by size, so the choice also affects the tap fee.

Georgia Power's Lake Oconee guidelines allow irrigation pumps for single-family homes next to its land, provided the pump sits on land, is centrifugal, does not exceed 2.5 horsepower, and is installed and wired by a qualified electrician. That water is not potable and must never connect to the house's drinking-water plumbing.

Ready when you are
A water line is a long, narrow excavation that has to miss your septic system, your sewer and everyone else's buried utilities. We trench it, bed it, lay the pipe and backfill it, from a single service line to a distribution system.
